Abstract: Zambia’s 2024 Eurobond restructuring, agreed in June 2024 under the G20 Common Framework, provided significant headline relief but included a performance-linked hazard known as the Upside Case, a trigger that converts the long-dated, low-coupon Bond B into a far more expensive instrument if Zambia’s economy performs well over the period January 2026 to December 2028. Using a scenario-based framework for net present value (NPV) calibrated to public terms and to the independent estimates of Debt Justice, this study answers three questions of direct relevance to policymakers, creditors, and citizens: the likelihood and consequences of activation; whether the clause represents a growth penalty; and how future restructurings can be designed to aid rather than tax recovery. The research reveals that activation would boost the NPV of repayments to around US$2.8 billion (approximately 51% above the Base Case), squeezing effective relief from about 44% to about 15%, with yearly Bond B interest increasing from less than US$7 million to more than US$100 million. The trigger was finely balanced, with the IMF Composite Indicator hovering between 2.58 and 2.60 against a 2.69 threshold, but recalculations using newer data placed it at the cutoff, while the export and revenue route strengthened on a copper-led rebound. The study demonstrates that the clause constitutes a genuine growth penalty because it is procyclical and asymmetric, reversing the countercyclical logic of state-contingent debt. The decisive evidence is Zambia’s own response: in June 2026 the Government repurchased 97.91% of Bond B, financed through a US$600 million African Development Bank loan, domestic reserves, and a novel energy-sector debt-for-development swap, while announcing a cleanup call to retire the residual by 25 June 2026, thereby extinguishing the trigger at a cost exceeding one billion US dollars. The study concludes by proposing a design agenda for growth-friendly and development-aligned sovereign debt restructurings.
