Ukraine's public debt stands at roughly 122% of GDP. In a conventional emerging market that number would be a warning; applied here it obscures more than it reveals. Understanding why is the difference between assessing Ukrainian sovereign risk and merely reacting to a ratio.
The starting numbers
| Indicator | Reading |
|---|---|
| Public debt to GDP | ~122% |
| GDP growth, 2026 forecast | 1.8% (NBU) to ~1% (independent) |
| Domestic borrowing cost | 15.2–16.2% recent placements |
| EU package, 2026–27 | €90bn, zero-interest |
| IMF EFF | $8.1bn over 48 months |
| Financing gap, 2026 | ~$52bn |
Why the ratio misleads in both directions
The denominator is compressed. GDP contracted sharply after 2022 and has not recovered. A ratio rises when the numerator grows or when the denominator shrinks, and a substantial part of Ukraine's increase is the second. Occupied territory, destroyed capacity and a reduced labour force mechanically inflate the ratio without any additional borrowing. Recovery in output would improve it without repaying a single hryvnia.
The composition is unusually favourable. Debt sustainability depends far more on the terms of the stock than on its size. A large share of Ukraine's external debt is concessional: the €90 billion EU package carries zero interest, IMF lending is at Fund rates, and G7 ERA loans are serviced from the profits of immobilised Russian assets rather than from Ukraine's budget. Debt at 122% of GDP at near-zero cost is a fundamentally different obligation from 122% at commercial rates.
The domestic component is expensive but small in relative terms. Government paper placing at 15–16% is a genuine cost, and it compounds. But it is the portion the state controls directly, and it exists partly to give domestic savers an instrument that beats inflation — a monetary and financial-stability objective as much as a funding one.
What actually determines sustainability
Three things, none of them the headline ratio.
Whether external support continues on concessional terms. This is the entire question. Ukraine's debt is sustainable in a world where partners keep lending at zero or near-zero cost, and it is not sustainable in a world where that stops and the stock must be refinanced commercially. The assessment is therefore political rather than financial.
Whether output recovers. Growth of 2.8–3.7% projected for 2027–2028 would begin repairing the denominator. Stagnation at 1% would not.
Whether reform conditionality holds. Concessional terms are contingent on programme compliance. The IMF's warning against retreating from reforms, issued with its July disbursement, is directly relevant to debt sustainability — the terms and the reforms are the same conversation.
The part worth stating plainly
Anyone holding Ukrainian government paper — including domestic savers attracted by 15–16% yields against 10% forecast inflation — is underwriting the continuation of international support. That is the risk, stated honestly. It is not primarily a bet on Ukrainian tax revenue or on GDP growth; it is a bet that partners keep funding the gap on terms the budget can carry.
That bet has been correct for three years and is currently supported by an €90 billion package and an active IMF programme. It remains a bet on political decisions in other capitals, and it should be sized as one.
Bottom line
At 122%, the ratio is high, the denominator is artificially compressed, and the composition is far more concessional than the headline implies. Sustainability rests on whether concessional support continues — which makes this a political credit rather than a fiscal one.
