Every clever debt structure carries a clause that can turn against it, and Zambia’s buyback has found its own. The instrument at the centre of the country’s restructuring was designed to reward recovery, but that same design is now the reason some creditors tried to stop the deal. The buyback that was meant to lighten the load comes attached to a trigger that could make it heavier.
The Clause: How the Step-Up Works
The US$1.36bn notes carry a step-up coupon. They pay a low 0.5% now, but that rate jumps to 7.5% if Zambia’s debt-carrying capacity improves, the kind of contingency built into restructured paper to share the upside of recovery with creditors. Frontier Markets News reported on 5 June 2026 that creditors sought to block the buyback over exactly this feature.
The logic of the objection is straightforward. A holder of paper that could one day pay 7.5% is being asked to sell it back while it still pays 0.5%, surrendering the upside the clause was meant to protect. The very mechanism that made the restructuring palatable has become the obstacle to retiring it.
A step-up of this kind is not exotic. Instruments that emerge from sovereign workouts often carry contingent features that let creditors recover more if the borrower’s fortunes turn, a way of bridging the gap between what a distressed government can promise and what lenders are willing to accept. The trade is deliberate: the country gets breathing room at a low coupon today in exchange for sharing the gains of any recovery later. Zambia accepted that bargain to exit default, and the bargain is now doing exactly what it was written to do.
The takeaway: a clause that rewards recovery also gives creditors a reason to hold on.
The Warning: What Fitch Flagged
Fitch warned that the step-up risk remains, and the warning matters for how Zambia’s improving story is priced. A rating agency keeping the step-up on its risk list tells the market that the country’s contingent liabilities are not fully resolved even after a buyback. The headline figure of debt retired is not the same as the risk retired.
This is the awkward edge of success. If Zambia’s economy recovers and its debt-carrying capacity genuinely improves, the trigger could fire and lift the coupon fifteenfold on whatever notes remain outstanding. Good news on growth becomes a fiscal cost, which is a difficult thing to manage and an unusual thing to explain. A finance ministry can find itself in the position of quietly hoping its own metrics do not improve too visibly before the paper is retired, which is an inversion of the usual incentive and a sign of how tightly the clause binds.
The takeaway: when recovery itself raises your interest bill, progress has to be carefully sequenced.
The Stakes: Why the Buyback Still Matters
None of this makes the buyback a mistake. Retiring paper that carries a built-in step-up removes the future liability before it can fire, which is arguably the most prudent reason to do the deal at all. The tension is one of timing and price: how much Zambia pays now to extinguish a risk that might or might not crystallise later.
For an operator reading the Zambian macro picture, the signal is to watch the resolution rather than the headline. How the dispute with creditors settles, and at what price, will say more about the country’s negotiating position and the credibility of its recovery than the size of the buyback itself. The Bank of Zambia and the Ministry of Finance are managing a delicate trade-off between cost today and contingency tomorrow, and the terms they accept will set a reference point for how the market reads the next restructured instrument the country issues.
The takeaway: the number that matters is not what is bought back, but what the step-up risk is settled for.
The Read
Zambia’s buyback is a test of whether a country can defuse a coupon time-bomb before its own recovery sets it off. The structure that helped the country exit default now has to be unwound carefully, with creditors who have every incentive to hold the upside. For anyone pricing Zambian risk, the clause is the thing to track, because it is where the next surprise will come from. The lesson sits one level above Zambia too: the features that make a workout possible are the same features a country must later pay to undo, and the cost of that undoing is part of the true price of the original deal.
