Long-term development is predicated on achieving relative sustainability, according to researchers and policy-makers alike. Most African economies rely on natural resource wealth to drive fiscal stability and development, but they are often buffeted by economic instability and uncertainty due to the inelastic nature of their export commodities on the international market. Any changes in commodity prices can lead to misalignments in the economy, potentially hindering economic development (Onyekwena & Edafe, 2024).

Moreover, as globalization has made nations relatively interdependent, most national economies are becoming increasingly susceptible to external shocks that affect their growth rate, either positively or negatively (Shykina et al., 2025). The World Economic Forum’s Chief Economist’s Outlook (January 2025), cautions that the global growth prospects are weak, with 56% of leading economists predicting weaker economic conditions, and highlighting that increasing debt and inflation present significant risks to macroeconomic stability (World Economic Forum, 2025).

Sub-Saharan Africa’s average annual GDP growth is projected to increase from 3.3% in 2024 to 3.5% in 2025, and then to 4.3% during the period 2026 to 2027, driven by stronger private consumption and investment, as inflation moderates and exchange rates stabilize (World Bank, 2025). Yet, this growth rate is not enough to significantly reduce poverty because many countries are facing high debt servicing costs, limited fiscal space, and continued exposure to climate and conflict-related shocks (World Bank, 2025; International Monetary Fund, 2024). To maintain macroeconomic stability and promote inclusive structural development, African countries need to rebuild their financial sectors, increase domestic resource mobilisation, and improve public financial management.

Recent data show that private banking credit in Sub-Saharan Africa increased from the early 1980s through to the 1990s. This was partly due to accelerated financial reform during 1986-1996 when numerous financial restrictions were removed, promoting access to long-term investment financing. Some scholars have recognized financial reform as an essential component of inclusive development, as it facilitates access to credit (Levine, 2005; Beck, 2011). Still, there are lingering concerns about the potential adverse consequences of financial liberalization, such as financial crises and economic volatility (Demirgüç-Kunt & Detragiache, 1998; Kose et al., 2006). More recent evidence suggests that while private sector credit in SSA continued to expand in the 2000s and 2010s, its growth has been uneven across countries, and financial depth remains significantly below the global averages (World Bank, 2023; International Monetary Fund, 2024). Scholars have further emphasized the dual challenge of deepening financial systems in order to support inclusive growth while safeguarding macroeconomic stability and resilience (Beck & Poelhekke, 2023). The question is: how have policies of financial sector reform in the past three decades influenced the achievement of macroeconomic stability on the African continent? Can the current level of macroeconomic performance be linked to the depth of financial sector reform in the SSA region over the past decades? In this regard, a possible policy for a developing country seeking to achieve long-term inclusive growth and macroeconomic stability is financial reform through financial intermediation and easier access to credit for the real economy.

Numerous studies have examined the correlation between resource availability and economic growth (Sachs & Warner, 1995; Sala-i-Martin & Subramanian, 2003; Carmignani & Chowdhury, 2010; Ogbeide & Mustapha, 2013; Ogbeide & Kanwanye, 2016; Mondjeli et al., 2024; Nwani et al., 2023). According to the extended Solow growth model, the abundance of resources hinders the trajectory of growth. Several scholars have studied the phenomenon of dependence on natural resources and its potential negative impact on economic growth, institutional quality, and civil peace. Auty (1993, 2001), Obadan & Obioma (1999), Beck (2011), Collier & Hoeffler (2005), Oyefusi (2007), and Mehrara & Rezaza (2011) have contributed to the understanding of how dependence on natural resources can lead to a decline in institutional quality and aggravation of civil conflicts, showing that the voracious rent-seeking behaviour of public officials plays a key role (Adegboye et al., 2022; Denly et al., 2022; Ezirim & Nwokolo, 2021; Djimeu et al., 2024).

This study aims to determine whether the presence of natural resources has a detrimental effect on the macroeconomic stability of Sub-Saharan African countries. This study focuses on examining the Staples theory of export-led growth, which emphasizes the significance of traditional commodities or staple products in the development of resource-rich economies (Mackintosh, 1967; Innis, 1967; Hartwick, 1977; Hamilton, 1983; Sid-Ahmed, 1989; Ploeg & Poelhekke, 2009; Odhiambo, 2021). The paper seeks to establish the role of financial sector reforms¹ and natural resource dependence in achieving macroeconomic stability on the African Continent. The existing studies have not investigated the impact of SSA countries’ income levels on the effects that natural resources and financial reforms can have on macroeconomic stability in the region. The present paper attempts to fill the research gap by bringing together these two important policy variables and strategies in a modelling framework. Unlike previous studies, it does not focus on one variable or strategy.

A systematic review of recent empirical literature has not identified any study that examines directly whether a country’s income level determines the combined effect of natural resources dependence and financial sector reforms on macroeconomic stability in Sub-Saharan Africa. Recent research has closely examined related moderation channels. For example, Nwani et al. (2023) investigated the role of financial development and institutions in mitigating resource-driven structural stagnation, while Taylor (2025) explored the fiscal and welfare consequences of resource dependence. These studies are relevant but they do not test income-level interactions that are the focus of our paper. This lack of exploration motivates our analysis, which specifically examines if income levels in Sub-Saharan Africa determine the impact of natural resources and financial reforms on macroeconomic stability indicators.

The paper is divided into five sections. Following this introductory section, section 2 reviews the relevant literature. Section 3 discusses the fundamental theory, methodology, and model specifications of the study. Section 4 presents the empirical results, and section 5 concludes with final remarks and policy suggestions.

Financial sector reforms have long been seen as an integral part of the policy agenda in developing countries. It was previously thought that they would improve the efficiency of resource mobilization and allocation in the real economy, leading to higher growth rates. Recent research has also considered financial reforms crucial for macroeconomic stability (International Monetary Fund, 2024; World Bank, 2025). Joya (2012) identified the main elements of macroeconomic stability, and outlined the components that contributed to sustainable growth of the gross domestic product, while maintaining low levels of unemployment and moderate volatility in prices. These included internal and external balances, and predictability in broad-based indicators of macroeconomics.

Resource abundance² and financial sector development through financial reform policies have a direct impact on both economic performance and the economy’s sensitivity to external events. Economists used to believe that having abundant natural resources is always advantageous. For example, Walter Rostow (1961), highlighted natural resource abundance as a requirement for taking off from the agricultural phase to industrial development in countries such as Australia, Britain, Canada, Sweden and the United States. According to Balassa (1980), the wealth of natural resources can help a country’s industrial development by providing funds for investment and creating demand through market links. However, recent theoretical and empirical research suggests that these resources might prove to be a hindrance. Auty (1993 and 2001) coined the term ‘natural resource curse’ to describe this phenomenon, and econometric evidence was provided by Sachs and Warner in 1995. They showed that countries with a high proportion of natural resources in their GDP experienced lower growth rates in the 1970s and were more vulnerable to economic shocks. The negative impact of natural resources on economic development should be examined, first, in terms of its effects on economic performance and potential for increased civil unrest and, second, the extent to which these effects determine institutional quality and governance. Recent evidence specific to SSA appears to support this hypothesis. Nwani et al. present panel data showing that resource dependence impedes structural transformation unless accompanied by stronger financial intermediation and improved institutional quality. Boulat uses a shift-share method to link mineral trade shocks with increased conflict in African local areas. Meanwhile, Mondjeli disaggregates resource types and forms of corruption to demonstrate the heterogeneous impact of institutions.

Inadequate management of a single natural resource that is narrow and inelastic can lead to institutional weakness and civil conflict. It can also promote greedy rent-seeking, which often neglects poor and disadvantaged people in the economy (Sachs & Warner, 1995; Sala-i-Martin & Subramanian, 2003; Oyefusi, 2007; Mehrara & Rezaza, 2011). The resource curse theory posits a negative correlation between the abundance of natural resources and a country’s long-term economic growth. The potential negative consequences associated with these resources may also be indicative of the “resource curse” phenomenon in the financial sector. This is because resource abundance and dependence can reduce the motivation for savings and investment. (Beck, 2011; Kurronen, 2015). Recent fiscal analyses (Taylor, 2025) show that resource windfalls in SSA have been linked to reduced non-resource tax effort, increased procyclical current spending, and weaker national savings rates. However, these effects can be mitigated if fiscal rules and institutional capacity are strengthened. Gravin and Hausman (1998), and Ross (2004) established a link between the abundance of natural resources and increase in poverty and inequality among the majority of the population of a country.

In contrast, Mauro (1995 and 1998) proposes a hypothesis which suggests that compensation for rent-seeking activities occurs more quickly than for productive work, leading to talent misalignment. The countries in question consistently express concerns about managing the effects of fluctuating commodity prices on macroeconomic and financial stability. Fluctuation in commodity prices poses challenges for both fiscal and monetary policymakers because of its consequential impact on exchange rates, export revenues, economic output, and employment levels. Aghion and Banerjee (2005) site empirical evidence pointing to the detrimental impact of volatility on investment and economic growth. Recent policy reviews (IMF, 2024; World Bank, 2025) emphasise that commodity‑price volatility and high public debt narrow fiscal space and increase vulnerability of commodity‑dependent SSA economies.

Several studies have shown that the abundance of resources has a negative impact on economic performance. These include Gelb (1988), Gylfason, Herbertsson, and Zoega (1999), Kaldor, Karl and Said (2007), Sala-i-Martin and Subramanian (2003), and Sachs and Warner (1995). There is ample evidence that countries reliant on natural resources for economic stability often have weaker long-term rates of growth than countries with a more varied range of exports. (UNCTAD, 2012). Collier and Gunning (1999), Collier and Hoeffler (2005), Dabán and Helis (2010), and Guriev, Plekhanov, and Sonin (2010), have contributed to the academic literature on the role of institutional weaknesses in the adverse effects of resource booms. Besides, it has been argued that countries with rich natural resources often suffer from Dutch disease, as discussed in the works of Sala-I-Martin and Subramaniam (2003) and Achille (2008) and Arezky and Ismail (2010). More recent cross-country and sub-national analyses confirm existence of these relationships in SSA. Mondjeli et al (2024), provide disaggregated evidence of corruption channels that exacerbate the “resource curse” in specific contexts.

In light of these findings, Auty (1994) suggested that the resource curse theory was not an iron law, and that the availability of natural resources in huge deposits was not inherently harmful to economic growth, but rather, the government should resolve to avoid a subsequent rent-seeking behavior and institutional weaknesses through careful use of revenue from resource exports. Countries such as Australia, Botswana, Canada, Indonesia, Malaysia, Mexico and Norway are known to have avoided the resource curse by implementing pro-development policies and prudent macroeconomic measures. (Ross, 2001; Sy et al., 2012). The World Bank (2025) and IMF (2014 policy reviews) confirm that governance, fiscal framework, and institutional capacities are essential to avoid resource-related macroeconomic instability in sub-Saharan African countries.

Numerous studies in the field of finance and development have shown that countries with more advanced financial systems are likely to experience greater and faster increases in economic growth (Schumpeter, 1911; McKinnon, 1973; Shaw, 1973; Levine, 2005). Endogenous growth models emphasize the importance of financial development in promoting economic stability and growth in the real sector of the economy. Greenwood and Jovanovic (1990), Pagano (1993), King & Levine (1993), Greenwood and Smith (1997), and Acemoglu, Aghion, LeLarge, Van Reneen, and Zilbotti (2006), show how a well-developed financial sector can promote economic growth by optimally allocating scarce resources to investment. Some researchers argue that financial liberalization increases economic agents’ interactions through effective mediation between savers’ decisions and investment opportunities (Levine, 2005; Demirguc-Kunt, 2006; Ahmed & Islam, 2010; Beck, 2011). According to the financial liberalization thesis, liberalizing the financial sector supports domestic financial institutions, helps improve the effectiveness of monetary policy, and enhances the efficiency of intermediation and domestic savings. Guiso, Sapienza and Zingales argue that bank deregulation can enhance lending accessibility and lower interest rates through increased competition. They caution, however, that this deregulation could also lead to an increase in bad loans, posing a hidden risk to macroeconomic stability. Recent empirical studies on SSA have shown that the depth of the financial sector and strict supervision are crucial for maintaining stability and promoting growth (International Monetary Fund, 2024; World Bank, 2025).

The process of liberalizing domestic financial sector has the potential to increase the depth and resilience of a country’s financial system, making it better able to withstand various types of economic shocks (International Monetary Fund, 2008). This can help mitigate the negative effects of unfavourable terms of trade and changes in foreign interest rates on a country’s output costs. The enhanced accessibility of credit brought about by financial reforms has emerged as a crucial mechanism for stabilizing the overall economy. Allen and Gale (1997) argue that a liberalised financial system can improve a country’s ability to cope with shocks generated by the real economy as it strengthens the link between the real rector and the financial sector.

Chinn and Ito (2002) examined the relationship between capital account liberalization and financial development using panel data from 1977 to 1997. Their findings suggest that strong institutional quality, especially in terms of legal and property rights, is associated with a significantly positive correlation between financial development, measured by private lending and stock market activity, and the imposition of capital controls. These findings were largely consistent with data from developing and emerging countries. Chinn and Ito (2002) examined whether financial account openness promotes equity market development. They concluded that capital account openness deepened the stock market, or had a beneficial effect on it. Bekaert, Harvey and Lundblad (2005), and Tressel and Detragiache (2008), found that financial liberalization deepened the financial sector: financial reform promotes financial intermediation through improved risk management as more efficient foreign banks enter the market, increasing the availability of new financial products and services. Acemoglu and Zilibotti (1997) wrote about a potential relationship between financial depth and economic diversity, suggesting that financial depth may facilitate economic diversity, mitigate cyclical risks and thus attenuate cyclical swings. According to Greenwald and Stiglitz (1993), efficiency in financial markets helps reduce information asymmetry, which allows economic actors to process information more effectively, leading to a decrease in growth volatility. Furthermore, the study conducted by Aghion, Banerjee, and Piketty (1999) revealed a correlation between the development of the financial sector and unpredictability of economic growth, particularly in developing countries. According to Bekaert, Harvey, and Lundblad (2001), equity market liberalisation led to an average increase of 1% in real economic growth. This conclusion was drawn based on an analysis of four distinct sample sizes (28, 50, 75, and 95) spanning the period from 1980 to 1997.

Other researchers, however, have expressed skepticism regarding the veracity of the effects of financial liberalization, arguing that they have been overemphasized. Stiglitz (1993) and scholars associated with the Neo-Structuralist movement present a comprehensive analysis of potential benefits of fiscal repression for economic growth. They have identified three distinct mechanisms by which financial repression can exert a positive influence on the economy. Firstly, a decrease in interest rates can mitigate the probability of loan defaults arising from speculative actions undertaken by investors seeking to maximize their gains. Secondly, a decrease in interest rates generally leads to a reduction in the overall cost of capital. Thirdly, the implementation of selective credit programmes — a key component of financial repression — can promote lending to targeted sectors with the potential for significant technological spillover effects and inclusive economic growth.

A body of scholarly literature establishes a connection between banking crises and financial deregulation. Moreover, recent research has progressively shown a correlation between the frequency of financial crises and the increasing resolve of monetary authorities to promote liberalization within the domestic financial system. The objective of the present study is to examine the association between banking crises and policies of financial liberalisation, as explored by Demirgüç-Kunt and Detragiache (1998). These authors use data from a sample of 53 nations spanning the period from 1980 to 1995. The data indicate that financial systems which have undergone significant liberalization are more susceptible to banking crises. Demirgüc-Kunt and Detragiache also showed that the impact of financial liberalization on a volatile banking sector is limited, even in a stable institutional environment. The binary variable serves as a representation of the financial reform indicator proposed by Demirgüç-Kunt and Detragiache (1998). The variable assumes a value of one in the inaugural year when specific interest rates underwent liberalisation and a value of zero in all other instances. According to Seck and El Nil (1993), the potential influence of financial liberalisation on intermediation margins depends on various factors. Specifically, they suggest that lack of competition, together with interest rate liberalization, reduction of reserve requirements, and ease of entry into the banking sector, may hinder the expected fall in intermediary profits. According to the findings of Caprio (2000), based on a panel analysis, the presence of government control over banks is linked to higher probability of a financial crisis.

The study conducted by Anyanwu (1995) found that the implementation of financial reforms in Nigeria led to an improvement in the country’s financial sector. This conclusion was based on using M2/GNP as a proxy indicator for measuring the level of financial development. Based on the findings of Oyaromade (2005), it could be observed that financial liberalisation in Nigeria contributed to the expansion of the country’s financial market, enhancing its efficacy in facilitating financial intermediation. This resulted in an increased responsiveness of savings to fluctuations in financial variables. Obamuyi and Olorunfemi (2011) investigated the potential impact of financial reform and interest rates on the economic growth of Nigeria. Cointegration and error correction modelling techniques were employed to analyse time series data spanning the period from 1970 to 2006. The results of the analysis indicate that financial reform and interest rates exert a positive influence on economic growth. Fowowe (2011) conducted a study based on unbalanced panel data spanning from 1980 to 2006. The study revealed a noteworthy positive impact of financial reform legislation on private investment in Sub-Saharan Africa (SSA), which supports the financial liberalization hypothesis. In their study, Ogbeide and Adeboje (2020) examined the impact of financial reform policy on entrepreneurship in 22 Sub-Saharan African (SSA) countries using dynamic Generalised Method of Moments (GMM) models. They found that in these countries the outcome of financial reform policy did not have a consistent effect on entrepreneurship. The authors suggest that, to fully benefit from the growth-promoting effects of financial sector reform, comprehensive reforms should be implemented in the financial sectors of SSA countries.

In their study, Berube and Cote (2000), discovered that the coefficient associated with financial liberalization exhibited a significant positive impact on long-term savings in Canada. This suggests that the implementation of financial reform has yielded advantageous outcomes in terms of allocation of resources and mobilisation of savings. According the empirical findings of Burkett and Dutt (1991), financial reform is associated with increased volatility in production, which in turn leads to macroeconomic instability. Obadan (2006) argues that the susceptibility to a financial crisis in a country is heightened if its financial institutions show weaknesses or lack adequate regulation. Soyibo (1994), who used the M2/GDP ratio, noted a decrease in the financial depth of Nigeria after financial deregulations were implemented, specifically between 1987 and 1989. Nevertheless, there was also an increase in the financial depths in the subsequent years, 1990-1991. Based on discriminant analysis, Ikhide and Alawode (2001) showed that Nigerian banks’ health deteriorated after the introduction of financial reform policies. However, their study identified incorrect sequencing of policy initiatives as a major factor hindering the effectiveness of financial reforms. Arestis and Demetriades (1999) suggested that the banking sector instability observed in developing countries during the post-liberalization era could be attributed to an unsustainable increase in interest rates, which further intensified pre-existing information-related issues. In the absence of proper competition, financial liberalisation led to an increase in the disparity between interest rates on loans and deposits. This further exacerbated existing financial inefficiency in the region.

Demirguc-Kunt and Detragiache (1998) and Kaminsky and Smukler (2001 and 2002), have demonstrated that domestic financial liberalization has the potential to increase economic volatility and make economies more vulnerable to external shocks. One possible explanation is that financial liberalization can lead to increased risk-taking behaviors often resulting in higher default rates on loans. This happens because financial institutions may be more willing to finance businesses that are considered risky in order to have larger profits. The findings also indicate that information asymmetries arising from market distortions reduce the allocative efficiency of financial systems, thus adversely affecting economic growth. Recent analysis of Sub-Saharan Africa has found that rapid credit expansion not supported by regulatory infrastructure can sow the seeds of banking stress, as seen in Nigeria’s boom-and-bust lending cycles. (International Monetary Fund, 2025; International Monetary Fund, 2014).

Loayza, Schmidt-Hebbel, and Serven (2000) assessed the impact of financial liberalisation on the savings rate. They used a time-series macroeconomic dataset covering 30 years and encompassing both developed and developing countries. The study found that the process of financial liberalisation had negative consequences for individual savings. Moreover, the expansion of the banking sector and the increase in the real interest rate did not have a significant effect on the overall aggregate savings level. Bandiera, Caprio, Honohan, and Schiantarelli (2000) analyzed time-series data covering the period from 1970 to 1994 for eight countries. Their findings were consistent with previous research, as they also found no empirical evidence to support a positive relationship between real interest rates and savings. However, more recent studies on panel data suggest that in SSA (Sub-Saharan Africa), greater financial development can reduce macroeconomic volatility by improving the smoothness of consumption and the absorption of shocks.

Financial reform has had varying effects on macroeconomic stability in different countries. Having been successful in some of them, it could have failed in others. The Indian economy has exhibited a sustained pattern of robust development. This has helped mitigate the adverse effects of South East Asian crises, and India has accumulated substantial foreign exchange reserves. It has also proactively repaid part of its external debt and implemented measures to restructure domestic debt. Similarly, sub-Saharan African economies with prudent reserve management and fiscal buffers have fared comparatively well during the process of financial sector liberalisation (World Bank, 2025). Ikhide (1996) classified efforts to initiate change in the financial sector in Nigeria into five main areas: restructuring the financial system; reform of monetary policy; foreign exchange reform; liberalization of capital movements; and reform of the capital market. Each of these areas has yielded measurable results.

In summary, the literature provides valuable insights into the link between financial reforms, natural resource use, and economic performance. However, there is a noticeable gap in explicitly modelling these interactions within a coherent growth framework. To address this challenge, the next section outlines the theoretical framework and methodology adopted in this study.

Building on the insights from the literature review, which highlighted both the contributions and gaps in understanding how natural resources, financial reforms, and country-specific factors influence macroeconomic stability, this study now turns to the theoretical and methodological framework. To formally investigate these relationships, the analysis employs the standard Cobb–Douglas production function as the starting point. In line with the traditional Solow growth model, the following aggregate CD production function with two-factor inputs as specified in Equation 1:

Y=f(K,L)=AKtαLt1−αwhere0<α<1 (1)

Labour (L) and capital stock (K) as input into the production process are well known in economic theory to contribute significantly to achieving the desired level of output. In Equation (1), output (Y) denotes macroeconomic instability. We quantified macroeconomic instability by creating a misery index³ for each country. The economic misery index is employed as the dependent variable, whereas aggregate financial reform and other control variables are used as explanatory variables, in line with extant literature. The primary objective is to determine if financial sector reform policies and resource dependence exacerbate or alleviate macroeconomic uncertainty in SSA countries.

We use an index derived from the financial reform database created by Abiad, Detragiache, and Tressel (2010), which includes data from 91 countries, to measure the extent of domestic financial reforms. The scope of our analysis was limited because only 14 sub-Saharan African countries were included in the database for the financial reform index. Financial reform or liberalization can be broadly categorised into two main types: domestic sector liberalisation and external sector liberalisation. Domestic liberalisation refers to the process of deregulating interest rates and reducing government intervention, particularly in the domestic financial sector. On the other hand, external sector liberalisation involves liberalisation of the capital account and implementation of policies in the securities market to encourage greater foreign participation in the domestic financial sector. For this study, a simple average of five elements from the financial reform database was used. These elements comprise credit controls, interest rate liberalisation, entrance and exit barriers, government ownership of banks, and prudential regulation and banking supervision. The index of securities market legislation and capital account reform were excluded from the analysis. The variable A represents the degree of technical advancement and is expected to remain constant.

To modify the CD function, we include a finance variable as an input to the production process to create output. The modelling technique is based on the idea that financial intermediation is a significant input that leads to widespread economic benefits. Financial reform policies play a crucial role in mobilization of savings within the financial sector, which enables the provision of essential credit to individuals and businesses seeking funds for investment purposes. These policies boost income and economic performance. Financial reform is added to the Comprehensive Development (CD) strategy to achieve macroeconomic stability. Equation (1) above has been modified to take into account the typical economic structures of most countries in SSA, which are broadly driven by revenue from natural resources (NR) that is used to finance growth-inducing economic activities.

Y = f (FINR, K, L, NR) (2)

Using the dynamics of K and L in a typical economy, we know that, at time t, K is determined by savings (a function of interest rate) and income from labour, whereas Labour, L, is determined by the population’s natural growth rate. Equations (3) and (4) depict the Capital and Labour, K and L, dynamics over a 2-period case.

∑t=12[Kt]α=St⋆Rt−i⋆Lt⋆Wt (3)

∑t=12Lt=(1+n)∗Lt≈Lt(1+n) (4)

Functional form Equation (2) is modified by introducing Capital and Labour, K and L dynamics, and our estimated model is put in a natural log-form, including an error term and a constant, which results in Equation (5):

Y=α0+α1( FinR t)+α2(St)+α3(Rt)+α4(Wt)+α5(Ht)+α6(NRt)+εt (5)

Where InY is the extent of macroeconomic stability (captured by Misery index); In (FinR_t) represents financial reform index computed from the financial reform database for the 14 Sub-Saharan African economies. We expect policies of financial reform to positively influence macroeconomic stability outcomes for included countries; In (S_t) is national savings growth; In (R_t) is interest-rate variables; In (W_t)is growth in wealth-related variables; In (H_t) is proxy by secondary school enrolment rate, capturing human capital development at time t; In (NR_t) is rent from natural resource export. All variables except those expressed in growth rates, which are already in percentage form, are expressed in their absolute values and then transformed using natural logarithms. The present analysis uses yearly data spanning from 2000 to 2021 for a panel of 14 African nations and their corresponding income classifications, as detailed in the Appendix.

The financial reform index was derived from a financial reform database developed by Abiad et al. (2010). This database was subsequently expanded by Ogbeide and others in (2020). The development of the financial reform index required careful examination of seven factors that have an impact on the banking sphere. These factors include stringent credit controls and reserve requirements, controls over the interest rates, barriers that hinder market entry, government ownership in the banking sector, limitations on capital accounts, regulations and supervision aimed at ensuring the stability of the banking sector, and policies related to securities markets. Each factor was evaluated and assigned scores ranging from 0 to 3, following the methodology of Abiad et al. (2010), indicating the degree of advancement on the indicators within the respective countries. In contrast to previous studies on financial liberalization (Edison & Warnock, 2003; Kaminsky & Schumkler, 2002), which had a narrow focus on the financial sector, Abiad et al. (2010) proposed a comprehensive index to assess financial reforms. This index assesses the degree of financial sector liberalisation in each country by considering seven fundamental components of the industry. The present study adopted a similar methodology. An annual calculation is performed to determine the financial reform index for each country, which involves the combination of seven different parameters related to financial reform. Given that each of these parameters take on values ranging from 0 to 3, their sum yields a value within the range from 0 to 21. Therefore, the lowest possible financial reform score that a country can attain in a given year is 0, and the highest possible score is 21.

We used the GMM technique to obtain reliable results by including lagged dependent variables as regressors. Because highly biased and inconsistent OLS (ordinary least squares) can lead to unsatisfactory results, we employed both the fixed-effects model and random-effects model. The Hausman model specification test was conducted to determine the preferred model, which was then compared with system GMM estimates.

Furthermore, this study investigated the extent to which financial reform is associated with macroeconomic stability, by examining whether income levels matter. We accounted for the income effect by conducting independent panel data estimations for countries with different income levels. The sample used in the study covers three out of four income classes in the World Bank classification (2023). The list of countries and their income classes can be found in Appendix 1. The OLS technique was only used for South Africa, as it is the only country in the upper-middle-income group.

This study aimed to examine the effects of domestic financial reform on macroeconomic stability in 14 countries in Sub-Saharan Africa (SSA). To do this, it used both static and dynamic panel data modelling techniques. The sample size was determined by the number of SSA countries that have implemented gradual financial reform, as outlined in the study conducted by Abiad et al. (2010) and extended in accordance with the established approach described in the literature. The study examined the time-series characteristics of each data set and investigated whether income levels played a role in the relationship between financial sector liberalization and macroeconomic instability in SSA countries, using World Bank income groupings. The results of this study confirm the dual and often contradictory effects of financial sector reforms on macroeconomic stability in Sub-Saharan Africa. While reforms were found to worsen instability in lower- and upper-middle-income countries, they contributed to stability in low-income economies. This outcome reflects the uneven pace of institutional development across the region, where fragile supervisory systems in middle-income economies often leave financial systems exposed to volatility. Conversely, in low-income economies, reforms that expand access to finance have created channels for resilience by promoting financial inclusion and consumption smoothing. These findings highlight the need for differentiated reform strategies that are sensitive to income levels and the maturity of financial institutions in each country.

The evidence on natural resource rents further reinforces the resource-curse thesis, as dependence on resource revenues was shown to have a generally destabilizing effect across SSA income groups. However, the overall panel results suggest that, when resource rents are effectively managed, they can serve as buffers to stabilize the economy. The contrasting effects emphasize that resource abundance in itself is not inherently harmful; rather, the quality of governance, fiscal institutions, and the capacity to implement counter-cyclical policies determine whether resource revenues translate into stability or volatility. This result is particularly relevant given recent commodity price shocks that have once again exposed the vulnerability of resource-dependent African economies.

The findings also reveal a “human capital-misery trap,” where higher levels of secondary school enrolment were associated with greater macroeconomic instability. This paradox suggests that a gap between human capital development and economic structure can lead to underemployment and frustration, contributing to economic instability. It emphasizes the importance of matching educational policies to labor market realities, promoting vocational training and technical education that can drive structural transformation and industrialization. Inflation and government consumption were also found to exert mixed but significant effects on macroeconomic stability, underscoring the critical role of prudent fiscal and monetary management.

From these results, several policy implications arise. First, financial reforms must be sequenced carefully and accompanied by stronger regulatory and supervisory frameworks. Best practices can be drawn from countries such as Kenya and Ghana, where gradual liberalization was complemented by regulatory strengthening, compared to Nigeria, where abrupt liberalization in the 1980s and 1990s heightened instability. Strengthening central bank independence, improving risk-based supervision, and deepening capital markets can help ensure that financial reforms deliver stability rather than volatility.

Second, the management of natural resource rents requires stronger institutional frameworks and fiscal rules that ensure that revenues are directed into stabilization funds, sovereign wealth funds, or productive investments. Botswana offers an example of prudent management of diamond revenues, which helped sustain macroeconomic stability over decades, in contrast with Nigeria, where oil revenue dependence amplified instability during price downturns. SSA governments should also expand non-resource tax bases to reduce vulnerability to commodity price shocks and pursue long-term diversification through targeted investments in agriculture, manufacturing, and services.

Third, to address the human capital-misery trap, education policies should be reoriented toward demand-driven skills. Expanding vocational and technical training linked to industrial policies can provide immediate employment opportunities while aligning labor supply with productive sectors. This approach is essential to prevent underemployment of educated youth, which often contributes to social unrest and political instability.

Finally, macroeconomic stability requires coordinated policy frameworks that balance fiscal and monetary policy. Inflation management should avoid excessive reliance on monetary tightening that stifles growth; instead, governments must complement monetary policy with disciplined fiscal expenditure and measures to reduce structural inflationary pressures, such as food price volatility. Public spending should focus on social and economic infrastructure that enhances productivity while being implemented under strong accountability frameworks to minimize rent-seeking.

Therefore, this study contributes to the literature by showing that the relationship between financial reforms, natural resources, and macroeconomic stability in SSA is conditional on income levels and institutional quality. It underscores that one-size-fits-all policy prescriptions are inappropriate for the region. Effective policies must be country-specific, sequenced carefully, and accompanied by institutional strengthening. Only then can financial reforms and natural resource wealth serve as instruments of stability and long-term development rather than sources of fragility.
