A debt ratio falling this sharply usually means one of two things: either an economy has grown its way out of the problem, or the debt itself has been rewritten. For Zambia, it was the latter. According to the International Monetary Fund's sixth review of its Extended Credit Facility, Zambia's projected debt service-to-revenue ratio will average 13.4 per cent between 2026 and 2031, successfully falling below the multilateral lender's 14 per cent sustainability threshold. This data point represents the mathematical culmination of the sovereign's comprehensive restructuring under the G20 Common Framework. Ministry of Finance statistics indicate that total public debt declined from 133 per cent of gross domestic product at the close of 2023 to 86 per cent by mid-2025.

The restructuring required a fundamental transition in domestic fiscal architecture over a condensed timeframe. Following its 2020 sovereign default, the state relied heavily on accumulating arrears to fund operational budget deficits. The accumulation of external arrears had severely constrained state operations. The multilateral intervention -- which secured agreements on 94 per cent of debt within the restructuring perimeter by early 2026 -- resolved immediate maturity walls by terming out repayment schedules. Think of it as a debt that once arrived all at once, like a single overdue bill, now spread across a much longer corridor of smaller payments. By shifting from an era of rapid default accumulation to a smoothed redemption curve, the government was able to stabilise the overarching debt stock. However, securing these terms was contingent upon the implementation of rigid fiscal consolidation measures designed to systematically close the structural deficit between domestic revenue and state expenditure.

The analytical core of Zambia's restored debt sustainability lies in the mandated elimination of systemic state subsidies and the application of proactive monetary policy. The International Monetary Fund programme necessitated the removal of implicit fuel subsidies and the restructuring of tariffs at the state utility, ZESCO, directly improving overarching public cash flows. There is a structural irony here. The same kind of subsidy spending that helped build the pressure which led to the 2020 default is precisely what creditors then required the government to remove as a condition of relief from that default. Concurrently, the Bank of Zambia maintained a strict monetary policy stance -- holding a 14.50 per cent policy rate for much of 2025 before executing a marginal reduction to 14.25 per cent late in the year. Bank of Zambia reports confirm that this monetary tightening, combined with a resurgence in copper production and export revenues, drove a significant appreciation of the kwacha. This currency strength organically suppressed the domestic cost of servicing dollar-denominated external liabilities, mathematically improving the sovereign's debt service-to-revenue ratio.

Maintaining this trajectory requires stringent adherence to new fiscal targets. The 2026 national budget targets a record primary surplus of 4.1 per cent of gross domestic product on a cash basis, an objective that demands continuous domestic revenue mobilisation. Rating agencies, including Moody's and Fitch, have acknowledged the technical completion of the commercial debt exchange through positive post-default rating actions. Both, however, caution that long-term solvency remains vulnerable to external commodity shocks. To mitigate hot-money volatility, the central bank has deliberately capped non-resident participation in primary domestic bond issuances at 15 per cent over the medium term. The restructuring architecture successfully averted continued default. What it has not done, and was never designed to do, is guarantee that growth will outpace the cost of new capital.

This post-restructuring macroeconomic profile closely parallels the trajectory observed in Ghana. Following its own G20 Common Framework debt exchange, Ghana also experienced an initial mathematical reduction in overarching debt-to-GDP and immediate debt servicing pressures, supported by a parallel International Monetary Fund programme. Ministry of Finance data from both nations highlights a shared structural vulnerability. The immediate mathematical relief provided by creditor haircuts and term extensions generates vital fiscal space, but the continuous demand for aggressive domestic taxation heavily constrains organic private sector growth. For both sovereigns, the data demonstrates that while multilateral interventions can resolve immediate liquidity crises, the long-term overhang of commercial debt cycles continues to dictate restrictive domestic economic policy.
