Ukraine's government has committed to funding the coming period without raising headline taxes. Fiscal pressure is rising anyway, and the mechanisms by which it does are more instructive than any single budget line.
The pressure points
| Source | Direction |
|---|---|
| Petrol excise, 2026 | rising from €271 to €300 per tonne |
| Petrol excise, 2027 | €330 per tonne |
| Public debt to GDP | ~122% |
| Domestic borrowing cost | 15.2–16.2% on recent placements |
| Subsidised mortgage programme | ongoing budget commitment |
| GDP growth, 2026 forecast | 1.8% (NBU) to ~1% (independent) |
How pressure arrives without a tax rise
Excise trajectories are legislated, not announced. Fuel duties are scheduled to rise through 2026 and again in 2027. This is a tax increase in effect — it raises the price of a good that flows into the cost of nearly everything else — but it does not read as one politically, because it was decided earlier and is partly framed as EU harmonisation.
Debt service compounds. Borrowing domestically at 15–16% while the economy grows at one or two percent means debt service claims a rising share of revenue arithmetically. External support arrives largely on concessional terms, including the zero-interest EU package, which mitigates this considerably — but the domestic component is expensive and it accumulates.
Subsidy commitments extend forward. Every preferential mortgage issued under єОселя at 3% or 7% against a 15.5% policy rate commits the budget to covering that spread for the life of the loan. The cost of a programme is not what it disburses this year; it is the stream of compensation payments already contracted.
A narrow base under strain. Growth of one to two percent does not expand the tax base meaningfully, while informality remains high — one of the structural issues the IMF programme explicitly targets.
Why this constrains policy
The practical consequence is that Ukraine's fiscal space is set externally rather than domestically. With a financing gap around $52 billion for 2026 and total international assistance projected above $53 billion, the budget is balanced by decisions made in Brussels, Washington and G7 capitals, not by revenue decisions in Kyiv.
That has a specific implication for the reform conditionality attached to those flows. When external financing covers a gap of this magnitude, conditions attached to it are not advisory. The IMF's caution against retreating from reforms, delivered alongside its July disbursement, describes exactly this dynamic — the fiscal position leaves no room to decline the terms.
What to watch
The subsidy line is the most likely place for adjustment, because it is discretionary in a way that defence and social spending are not. Any reduction in єОселя volumes would be felt immediately in residential transaction activity, where subsidised lending currently drives a large share of demand.
The second is the excise path itself. It is a reliable revenue source and it is already legislated through 2027 — but it also guarantees continued upward pressure on fuel, which was the single largest contributor to inflation this year at roughly 0.7 percentage points. Fiscal policy is therefore working against the National Bank's inflation objective in one specific and measurable channel.
Bottom line
Taxes do not need to rise for the fiscal squeeze to arrive: legislated excise increases, compounding domestic debt service and forward subsidy commitments deliver it regardless. The binding constraint is external financing, which means the terms attached to that financing set the boundaries of domestic policy.
