In October 2025, the International Monetary Fund upgraded its growth forecast for sub-Saharan Africa to 4.1 percent, reflecting modest optimism amid persistent headwinds. That figure underscores a region balancing between promising reform momentum and foundational structural risks. Key pressures loom large: rising debt service costs, tightening external financing, inflation pressures, and weak fiscal buffers.
During the IMF’s African Department press briefing, Director Abebe Aemro Selassie highlighted that growth in 2026 may see a modest pickup, but warned that risk intensification is real. The future trajectory hinges heavily on domestic revenue mobilization, debt sustainability strategies, and more efficient public spending.
Against this backdrop, the nine nations under focus—Zimbabwe, Zambia, Uganda, Rwanda, Tanzania, Kenya, Nigeria, Burundi, and Ghana—offer instructive case studies of how African states are confronting crises and opportunities in 2025.
Zimbabwe: Reforms, Arrears & the Path to Credibility
Zimbabwe has long faced acute debt stress, currency instability, and liquidity constraints. In October 2025, the IMF publicly acknowledged that recent reforms—particularly limiting central bank financing of fiscal operations and efforts to stabilize the exchange rate—represent positive steps toward macroeconomic normalisation.
Yet, despite these reforms, Zimbabwe’s access to new IMF lending remains blocked due to massive outstanding arrears estimated at US$12.2 billion, owed to creditors like the African Development Bank, World Bank, and bilateral lenders.
In response, the IMF and Harare have embarked on a structured dialogue anchored in a staff-monitored program (SMP)—a framework that does not require full Board approval but is designed to build policy discipline and credibility as Zimbabwe works toward debt resolution and eventual normalization.
Zimbabwe’s roadmap includes targeting bridge financing of US$2.6 billion by mid-2026, negotiating arrears clearance, and serial commitments to structural reforms in governance, public finance, and external sector liberalization.
Outlook & Risks:
If Harare can maintain reform consistency and debt credibility, it may gradually unlock new development financing.
However, risks remain high: inflationary pressures, exogenous shocks (commodity price volatility), and a fragile social contract may derail progress.
Zambia: Nearing the Exit from Default
Zambia, after nearly four years in a de facto sovereign default, has made significant strides in restructuring external liabilities. Over 90 percent of holders of nearly US$4 billion in external dollar bonds endorsed the restructuring plan—crucial for avoiding a prolonged debt impasse.
That success hinges on further negotiations with Chinese and private commercial creditors, where unresolved claims still amount to more than US$3 billion.
The restructuring involves reducing face values, extending maturities, and payment relief—measures designed to bring debt service burden into sustainable alignment and signal Zambia’s willingness to fulfill obligations on realistic terms.
With the staging of an IMF bailout program also underway, Zambia now stands at a crossroads: cementing hard-won credibility or risking a relapse into default stress if implementation falters.
Implications for Zambia:
Lower yields and risk premiums may resume on Zambian external issuance.
Improved investor confidence could unlock more foreign direct investment.
However, macro vulnerabilities—drought, revenue shortfalls, governance gaps—remain binding constraints.
Kenya: From Debt Stress to Digital Financial Leadership
Kenya is navigating a delicate balancing act: high debt servicing burdens, political pressures, and an ambition to lead digital finance innovation in Africa.
Converting Dollar Debt to Yuan
In early October 2025, Kenya announced the conversion of a US$5 billion railway loan from U.S. dollars to Chinese yuan. The objective: reduce interest burden, mitigate currency risk, and manage debt servicing volatility. The finance minister projected savings of approximately US$215 million annually from the shift.
This maneuver signals growing sophistication in debt structuring—leveraging alternative debt instruments to ease fiscal pressure.
Crypto Regulation Law Passed
A landmark in East Africa, the Kenyan Parliament approved the Virtual Asset Service Providers Bill, creating a regulatory framework for cryptocurrencies and stablecoins. Under the new law, the Central Bank of Kenya will license stablecoins, while the Capital Markets Authority will regulate crypto exchanges and trading platforms.
That move positions Kenya to attract global fintech investment (e.g. Binance, Coinbase) and bring legitimacy to youth-driven digital asset usage. It also aligns with Kenya’s broader ambition to become a fintech hub.
Sovereign Wealth & Infrastructure Funds
To reduce dependence on debt, President William Ruto announced two new financial vehicles: a sovereign wealth fund and an infrastructure fund, to be capitalized via privatization proceeds. The first share offer is expected from Kenya Pipeline Company, aiming to raise KSh130 billion (~US$1.01 billion).
These funds are intended to finance strategic sectors—agriculture, power, industry—while preserving fiscal space and reducing reliance on debt.
IMF Visit, Reforms & New Programme
Simultaneous to these moves, an IMF staff mission visited Kenya to assess macro risks and prioritize structural reforms in public finance, external sustainability, and institutional strengthening.
Kenya’s prior IMF program expired this year. The country is now courting a new agreement that would anchor external debt repayment efforts and restore fiscal confidence.
Risks & Opportunities for Kenya:
Successfully regulating crypto may attract capital but also requires robust supervision to prevent misuse.
Sovereign funds offer fiscal innovation, but execution must avoid governance pitfalls.
The debt conversion strategy is attractive, but shifts exposures to Chinese currency and creditor risk.
A new IMF program may provide policy anchor, but conditionality could be politically sensitive.
Nigeria & Ghana: Financial Markets, Fintech & Macro Pressures
Nigeria: Upgraded Growth, Fintech Surge
The IMF’s revised regional outlook raised Nigeria’s 2025 GDP forecast to 3.9 percent, reflecting stabilizing commodity prices and reform momentum.
Nigeria’s fintech sector continues its ascendancy: large scale digital payment platforms, micro-lending apps, and embedded finance are reshaping how individuals and small businesses transact.
Yet the country still wrestles with inflation, exchange rate stress, and policy continuity concerns that may hinder foreign portfolio inflows.
Ghana: Inflation Relief & Market Optimism
In Ghana, inflation recently dipped below 10 percent—a first since 2021—offering relief to households and triggering renewed investor interest.
Equity markets responded positively: Ghana’s stock index (GSE-CI) rose over 3.5 percent in early October, boosted by gains in banking and industrial counters.
Still, the risk of external financing gaps and debt rollover challenges looms for Accra.
Uganda, Rwanda, Tanzania & Burundi: Case Studies in Resilience, Integration & Innovation
Uganda & Rwanda: Fast Growth, Fintech Adoption
Uganda and Rwanda stand among Africa’s fastest-growing economies. As noted in IMF commentary, both nations are among those leading growth in the region.
Their strengths lie in focused reforms, digital financial push, and lower debt burdens. Fintech firms such as Numida in Uganda, providing mobile microcredit to SMEs, reflect the innovation underway.
Rwanda’s lean governance model has enabled modular scaling of fintech tools, digital ID, mobile money, and cross-border digital services.
Tanzania: Balancing Natural Resources & Fiscal Reform
Tanzania’s resource wealth in gas, minerals, and agriculture is a latent advantage, but converting that into growth requires careful public investment and debt discipline. The country has avoided severe crisis episodes thus far, but must contend with inflation, revenue constraints, and global capital conditions.
Burundi: Fragility, Debt & Development Gaps
Burundi remains one of the more fragile economies in East Africa. Low per capita income, high aid dependence, limited export diversification and weak institutional capacity make it especially vulnerable to external shocks and policy missteps.
Africa’s Debt Dynamics & Domestic Borrowing Risks in 2025
A central theme across these countries is rising domestic debt—a double-edged sword. The IMF recently warned that sub-Saharan governments’ increasing reliance on domestic borrowing is crowding out private investment and heightening banking sector vulnerability.
In many states, internal debt is now more costly than external borrowing due to shallow financial markets, illiquidity, and high spreads.
Such dynamics create a feedback loop: governments borrow more domestically → banks concentrate exposure to sovereigns → financial stability weakens, reinforcing sovereign risk.
A more sustainable path demands stronger debt management, transparent borrowing practices, market development (e.g. local currency bond markets), and selective external borrowing.
Regional Integration & Digital Finance: The COMESA Payments Breakthrough
A major development in regional integration arrived in October 2025 when COMESA launched a Digital Retail Payments Platform, enabling cross-border trade in local currencies without converting to U.S. dollars.
In a pilot phase between Malawi and Zambia, the system aims to reduce transaction costs (target <3 percent) and enhance financial inclusion for SMEs.
That platform represents a potential paradigm shift: de-dollarized trade within Africa, improved liquidity, and deeper regional economic cohesion. Kenya, as the new COMESA chair, has emphasized its importance.
The platform is also synchronized with Kenya’s push into fintech and digital asset regulation, positioning the country as a regional digital finance anchor.
Beyond COMESA, such integration may catalyze more interoperable payment rails, pan-African settlement systems, and macro financial stability.
Fintech as Africa’s Growth Engine: Scale, Risk & Promise
Across the nine countries, fintech is not just a buzzword—it’s central to financial inclusion, credit access, and capital flow. In fact, seven of Africa’s top 20 fastest-growing companies (by revenue CAGR) are fintechs, spanning Nigeria, Kenya, Zambia, Ghana, Rwanda, Uganda and others.
Examples:
eShandi (Zambia): Mobile lending, payments, and insurance services operating across Zambia, Kenya, Zimbabwe.
Numida (Uganda): Microfinance via mobile lending tools targeting small businesses.
PalmPay (Nigeria): Large mobile payments ecosystem.
These firms are scaling revenue 150–500 percent annually, reflecting:
Underserved markets (tremendous unmet credit demand)
Mobile penetration and digital infrastructure enabling leapfrogging
Demand for seamless payments, savings, lending, insurance
Challenges ahead:
Regulatory clarity and consumer protection (as seen in Kenya’s crypto law)
Credit risk, fraud, cybersecurity
Monetization models and sustainability
Interoperability across platforms, currencies, and jurisdictions
If carefully regulated and integrated with public systems, fintech may unlock new capital flows, especially for SMEs and rural actors.
Policy Prescriptions & Strategic Imperatives for 2025–2026
From the patterns across these nations, certain lessons emerge for governments, investors, and multilateral institutions:
1. Anchor Credibility through Transparent Reforms
To attract capital and restore market confidence, countries must demonstrate consistency in public finances, open procurement, anti-corruption, and adherence to macro frameworks (e.g. via staff-monitored programs).
2. Strategic Debt Structuring & Restructuring
Debt conversion (e.g. Kenya’s yuan switch) and managed restructuring (e.g. Zambia) must be balanced to address immediate pressures without replacing one risk with another. Currency risk, creditor mix, and maturity profiles matter.
3. Advance Domestic Revenue Mobilization
With external financing contraction, revenue mobilization is essential. Digitization of tax systems, broadening tax base, eliminating inefficient exemptions, and strengthening compliance are vital (an IMF priority).
4. Deepen Local Capital Markets
Robust government bond markets in local currencies reduce reliance on external debt. This requires investor development, transparency, and better regulation.
5. Adopt Progressive Digital Finance Regulation
Kenya’s crypto regulation, COMESA’s payments platform, and fintech advances show direction. Balanced frameworks that enable innovation while protecting consumers and preserving stability are key.
6. Strengthen Regional Integration & Currency Cooperation
Cross-border payments platforms like COMESA’s reduce currency friction, deepen trade, and localize capital flows. Expansion of such models across ECOWAS, EAC, SADC could catalyze deeper capital markets integration.
7. Prioritize Resilience & Climate Finance
Given climate stress (drought, commodity volatility), governments must embed resilience funding, blended finance instruments, and shock buffers into fiscal planning.
8. Mobilize Private Capital & Blended Finance
As traditional aid flows decline, leveraging private capital through guarantees, de-risking instruments, and public-private partnerships becomes ever more urgent.
