Africa Pays USD 75 Billion a Year Extra to Borrow Money. A New Rating Agency Wants to Change That. The Question Is Whether It Can Be Trusted.

The Tax That Nobody Calls a Tax There is a charge that every African government pays every time it borrows money on international markets. It does not appear as a line item in any budget. It is not negotiated in any treaty. It is not voted on by any parliament. But it is real, it is large, and it is extracted with the precision of a toll booth positioned at the only road into the capital market. It is called the Africa premium, and it is the difference between what African sovereigns pay to borrow and what comparably situated economies in other regions pay for the same money. Data from the IPI Global Observatory reveals that in 2024, African countries paid approximately 9 percent interest on dollar-denominated bonds, the highest rate of any emerging region globally. Latin America averaged 6.5 percent for comparable instruments. Emerging Asia averaged 4.7 percent. The spread between Africa and Asia, on debt with similar underlying economic characteristics, is 4.3 percentage points. On a continent where external debt repayments are projected to exceed USD 90 billion in 2026, that spread represents tens of billions of dollars annually in excess interest payments that flow out of African economies and into the balance sheets of international creditors. The United Nations Development Programme quantified the aggregate cost of this premium in a 2023 report that is worth sitting with for a moment. Subjective judgments about political risk and institutional strength, the report found, cost African countries an estimated USD 75 billion per year in excess interest and lost lending opportunities. To put that figure in context: it exceeds the entire Official Development Assistance flows to Africa in 2021, which totalled approximately USD 30 billion. The continent's governments collectively pay more in excess borrowing costs driven by rating methodology bias than they receive in total foreign aid. Africa is, in aggregate, a net exporter of development finance to the international capital system, not a net recipient. This is the structural reality that the Africa premium debate is about, and it is the context in which the establishment of an African Credit Rating Agency must be assessed. How Three Agencies in New York and London Price an Entire Continent Moody's, Standard and Poor's, and Fitch collectively control approximately 95 percent of the global sovereign ratings market. Their assessments determine whether institutional investors, pension funds, insurance companies, and sovereign wealth funds can hold a country's debt instruments at all, and at what yield they will demand to do so. This concentration of rating power is itself a structural feature of global capital markets that deserves more analytical attention than it receives. The Big Three agencies use assessment frameworks that combine quantitative measures, debt levels, GDP growth, foreign reserve adequacy, current account balances, with qualitative judgments about governance quality, institutional strength, political stability, and policy effectiveness. The quantitative components are relatively objective, though data quality variations between developed and frontier markets affect their accuracy. The qualitative components are where the structural bias argument is most substantive. A 2023 UNCTAD report on credit rating agencies and developing countries documented several forms of bias in rating assessments of African sovereigns. Home bias, where analysts located in New York and London apply frameworks calibrated against North Atlantic economic institutional contexts to economies whose institutional structures, market dynamics, and development trajectories are fundamentally different. Methodological bias, where indicators applied in rating scorecards generate different marginal impacts on ratings for African countries compared to similarly situated non-African sovereigns. And market power preservation bias, where the agencies' commercial interests in maintaining relationships with the major investors who use their ratings create incentives for conservatism in upgrading frontier market sovereigns whose investor base is smaller and less commercially significant. The practical consequences of this bias are visible in specific cases that illustrate the pattern rather than represent isolated anomalies. Nigeria's President Bola Ahmed Tinubu noted that Nigeria's November 2025 dollar-denominated bonds were oversubscribed 5.5 times by investors, reflecting market confidence substantially ahead of what sovereign ratings would suggest. The market was pricing Nigeria's debt at yields consistent with better credit quality than the rating agencies assigned. The divergence between market sentiment and agency assessment is precisely what the Africa premium thesis predicts: institutional investors relying on agency ratings pay more than the market's own risk assessment would require, and African governments bear the excess cost. The Afreximbank downgrade in 2025, when Moody's moved the institution from Baa1 to Baa2 and Fitch moved it from investment grade BBB-minus to junk status BB-plus, illustrates the systemic consequences when rating actions affect institutions rather than just sovereigns. Afreximbank functions as a critical bridge between international capital markets and African trade finance. When its rating falls, its borrowing costs increase, and those costs are passed through to the African countries and companies that rely on its financing. A rating action on a single institution transmits its effects across the entire continent's trade finance ecosystem. What This Means for the Uchumi360 Coverage Region The Africa premium is not an abstraction for the countries Uchumi360 covers. It is a specific and quantifiable drag on the development capacity of every government in the coverage region that accesses international capital markets. Tanzania's B+ rating, which Uchumi360's sovereign credit analysis documented in detail, places the country firmly in speculative grade territory. At current market rates for B-rated African sovereigns, Tanzania's international borrowing costs reflect the Africa premium in full. Every Eurobond Tanzania issues, every external commercial loan it takes to finance the infrastructure gap between its concessional financing access and its development investment requirements, carries a cost premium above what its genuine economic fundamentals would justify if assessed without the structural bias the UNCTAD report documents. The arithmetic connects directly to the investment surge analysis. Tanzania registered USD 10.95 billion in approved investment capital in 2025. A significant proportion of the public infrastructure investment underlying that surge, the road upgrades, the airport expansions, the port capacity additions, requires government financing that draws on the international capital markets where the Africa premium applies. Every basis point of excess yield on Tanzania's sovereign borrowing is a direct transfer from Tanzania's development budget to international creditors, money that would otherwise fund the infrastructure, health, education, and institutional capacity that would close the structural gaps the rating agencies themselves cite as justifications for the speculative grade assessment. The circularity of this dynamic is one of its most frustrating features. African governments are rated as speculative grade partly because their fiscal capacity is constrained. Their fiscal capacity is constrained partly because they pay excess borrowing costs driven by the speculative grade rating. The premium feeds the very condition that justifies it, and breaking this cycle requires either improving fundamental economic indicators, which takes time and investment, or challenging the rating methodology that is generating systematically high assessments of African sovereign risk relative to underlying economic reality. Zambia's debt crisis, which resulted in a default and restructuring process that dragged on for years, followed the same pattern documented in Ghana: successive rating downgrades drove up borrowing costs, reduced market access, and created a self-reinforcing deterioration that made eventual default more likely by the same mechanism it was supposedly warning investors about. The rating agencies did not cause Zambia's debt problems, but their downgrades accelerated the trajectory in ways that reduced the policy space available to manage the situation. The African Credit Rating Agency: The Ambition and Its Limits The African Credit Rating Agency, championed by African heads of state including Nigeria's President Tinubu and endorsed by the African Union, represents the continent's most structured institutional response to the Africa premium problem. The agency was originally slated for launch in September 2025, with first sovereign ratings expected in early 2026. As of the time of writing, the timeline has shifted and the launch is still pending, a delay that is itself symptomatic of the institutional development challenges AfCRA will need to overcome. The analytical case for AfCRA is straightforward. Rating assessments grounded in deeper, more current, more contextually specific knowledge of African economies, produced by analysts with direct familiarity with the institutional structures, policy dynamics, and economic realities of the countries being assessed, should in theory produce more accurate risk assessments than assessments produced from New York and London using sparse data and broad regional proxy indicators. More accurate risk assessments should close the gap between Africa's rated creditworthiness and its actual creditworthiness, reducing the premium that the mispricing imposes. The institutional challenges that AfCRA faces in delivering on this case are significant and deserve honest engagement rather than cheerleading. Misheck Mutize of the African Peer Review Mechanism, one of the architects of AfCRA's governance design, has been direct about the central credibility challenge: the agency must be designed to prevent the favourable bias that critics anticipate as the mirror image of the unfavourable bias it is being created to correct. An AfCRA that systematically upgrades African sovereigns regardless of their genuine credit condition would not reduce the Africa premium. It would create a parallel rating market that institutional investors would discount, generating two-tier pricing with African issuers still paying the premium when accessing mainstream capital that relies on Big Three ratings. The governance structure Mutize describes, with shareholding driven primarily by African private sector entities rather than governments, is designed to insulate the agency from political pressure to produce favourable ratings. Whether this structure is sufficiently robust to maintain credibility under the inevitable pressure that will arise when AfCRA's first assessments disappoint sovereign clients is the test that will determine the agency's long-term institutional value. The data quality challenge is equally fundamental. Part of the Africa premium reflects genuine information asymmetry: the Big Three agencies work with data that is often less current, less granular, and less reliably produced for African sovereigns than for OECD country sovereigns. AfCRA's ability to produce more accurate assessments depends on its access to better data than the Big Three currently use, which requires both investment in data collection and analysis capability and cooperation from African governments in providing timely, accurate, and comprehensive economic statistics. The same data quality gaps that contribute to current rating inaccuracies will constrain AfCRA's ability to produce the superior assessments its mandate requires unless they are addressed simultaneously. The Deeper Reform That AfCRA Cannot Substitute For AfCRA addresses the symptom of the Africa premium more directly than it addresses the structural conditions that the premium partially, even if imperfectly, reflects. This distinction is important for how the agency's potential contribution should be assessed. Some portion of the premium that African sovereigns pay is attributable to bias, data inadequacy, and methodological flaws in the rating agencies' approaches to African economies. This portion is genuinely reducible through better rating methodology, and AfCRA's contribution to better methodology, whether through its own assessments or through the competitive pressure it places on the Big Three to improve their African coverage, could meaningfully reduce borrowing costs for African sovereigns. But some portion of the premium reflects genuine risk that is accurately assessed. African economies face higher political risk, weaker institutional capacity, shallower financial systems, narrower export bases, and greater external shock vulnerability than their OECD counterparts. These are real characteristics that justify some yield premium above risk-free rates, and the honest goal of AfCRA should be to ensure that the premium reflects actual risk accurately, not to eliminate the premium by rating away the genuine underlying conditions that warrant it. For Tanzania specifically, the structural gaps that Uchumi360's credit rating analysis identified, the external account dependency, the revenue mobilisation constraint, the financial system shallowness, the informality that limits fiscal capture, are real conditions that the investment surge is beginning to address but has not yet resolved. A more accurate rating of Tanzania would still place it below investment grade. The legitimate case for AfCRA is not that Tanzania deserves a better rating than it currently has, but that the excess premium above accurately assessed risk should be reduced by more context-specific, more current, and less biased assessment methodology. That distinction, between eliminating bias and eliminating accurate risk pricing, is the analytical line that AfCRA's credibility will depend on holding clearly and consistently in its assessments. The Competition That Would Matter Most The most powerful mechanism for reducing the Africa premium is not institutional: it is competitive. The Big Three's dominance of the ratings market, at 95 percent market share, is itself a structural feature that reduces the incentive to improve African assessment quality. When an agency faces no credible competitor for the business of rating African sovereigns, the commercial incentive to invest in deeper, more accurate African coverage is limited. AfCRA's most valuable contribution to the Africa premium problem may not be its own ratings. It may be the competitive pressure its existence places on Moody's, S&P, and Fitch to improve the quality and accuracy of their African sovereign assessments in order to defend their market position. If AfCRA establishes credibility with a meaningful segment of institutional investors, the Big Three face a competitive incentive to narrow the gap between their assessments and AfCRA's more contextually grounded ones. That competitive dynamic could improve rating quality across the market more effectively than AfCRA's own ratings could achieve in isolation. This is the mechanism through which the African Credit Rating Agency could generate economic returns that justify the institutional investment it requires, even if its own ratings never achieve the global acceptance of the Big Three. The value of a credible African voice in the rating market is not only in the ratings it produces. It is in what its existence forces the incumbent agencies to do differently. The Bottom Line Africa pays USD 75 billion per year in excess borrowing costs driven partly by rating methodology that systematically overestimates African sovereign risk. This is not an academic argument. It is a development finance transfer of a scale that dwarfs official aid flows, extracted through the mechanism of credit ratings that shape institutional investor mandates and therefore the yields African governments must pay to access international capital markets. The African Credit Rating Agency is a legitimate institutional response to a real structural problem. Its credibility will depend on its willingness to issue downgrades where conditions warrant them, its independence from political pressure toward favourable ratings, and its investment in the data quality and analytical depth that would allow it to produce genuinely more accurate assessments than the Big Three currently provide for African sovereigns. For Tanzania and every other country in the Uchumi360 coverage region, the practical implication is direct. Better rating methodology that closes the gap between assessed and actual creditworthiness reduces borrowing costs. Lower borrowing costs increase the fiscal space available for the infrastructure, institutional development, and human capital investment that would close the structural gaps the ratings are assessing. The circle, between rating accuracy and development capacity, runs in both directions. AfCRA is an attempt to make it run in the right direction for once. Whether it succeeds depends on whether it can build the institutional credibility that the Big Three have accumulated over decades, in a fraction of the time, against the structural advantages of incumbency, and under the political pressures that will inevitably test its stated independence. That is a difficult task. It is also a necessary one. _______________________________________________________________________________________ Sources: Finance in Africa, Why Africa Is Pushing for Its Own Credit Rating System, 2026.
