Ukraine faces $27 billion 2026 defence funding gap, plans $7 billion in domestic cuts

Why it matters

The gap funds both immediate military payments and long-range and air defence capabilities that will determine Ukraine's position on the battlefield into early 2027. The $20 billion being negotiated with partners represents roughly 13% of Ukraine's stated 2026 war financing need, and failure to secure it would force deeper cuts to non-defence spending — the government has already frozen cultural programmes, road-repair debts and "Resilience Plan" infrastructure projects to close part of the gap.

What happened

Ukraine's government has identified a $27 billion shortfall in 2026 defence financing out of a total war financing need estimated at $155 billion, a figure first presented by the previous leadership of the Ministry of Defence at the Ramstein meeting in February 2026 and reaffirmed in the "Financial Strategy" document submitted to the EU in March 2026. Prime Minister Serhiy Koretsky outlined a plan to cover about $7 billion domestically through savings, optimisation and reallocation, which he described as a "strict regime of state finance austerity" involving postponement of non-priority expenditures. The remaining $20 billion is the subject of negotiations with international partners and is, according to Koretsky, critical to Ukraine's ability to conduct active combat operations into the first quarter of 2027, since weapons production — particularly long-range capabilities — must be paid for in advance.

President Volodymyr Zelensky first publicly cited the $27 billion figure on 24 August during a meeting of the "Coalition of the Willing," and Koretsky on 14 September described Ukraine's public finances as "close to critical." The government is also racing to meet conditions attached to $29.5 billion in partner budget support, working to fulfil all required obligations by 15 October and asking the Verkhovna Rada to hold a session on 12 October to vote on the necessary draft laws. Ukraine has approached the European Commission about bringing forward the second tranche of EU assistance originally scheduled for next year, as the IMF cannot finance military provision. Part of the funding is also expected to come from new "Drone Deal" arrangements with partners. MP Serhiy Rakhmanin, a member of the national security, defence and intelligence committee, told Radio NV he could not confirm or deny the $27 billion figure and characterised the deficit as more about underfunding than about debts.

Where reporting differs

Sources differ on how much of the $27 billion defence deficit can be closed through domestic reallocation. The government's plan, as stated by Prime Minister Koretsky, is about $7 billion via savings, optimisation and reallocation. Forbes Ukraine's analytical team puts the figure higher in potential terms, estimating the 2026 general fund defence budget deficit could be reduced to $6–8 billion by reallocating from other budget lines.

Background

The $155 billion total 2026 war financing need was first presented to partners by the previous leadership of the Ministry of Defence at the Ramstein meeting in February 2026 and was reaffirmed in the "Financial Strategy" document the government submitted to the EU in March 2026. The $155 billion includes both budget financing and off-budget partner material-technical assistance such as missiles — including PAC-2 and PAC-3 for Patriot systems — launchers, aircraft and other weapons provided in kind rather than as cash. Ukraine is negotiating a €90 billion concessional Ukraine Support Loan from the EU; the IMF cannot finance military provision, and Ukraine has asked the European Commission to bring forward the second tranche of planned EU support. Ukraine also risks losing $29.5 billion in partner budget financing if it fails to meet a set of international commitments tied to 15 October and to draft laws the Verkhovna Rada is being asked to consider on 12 October. Part of the deficit is expected to be filled through new "Drone Deal" arrangements with partners.
