Ukraine's 2026 defence deficit stands at $27 billion; $7 billion to be covered domestically, $20 billion sought from partners
Ukraine's government has confirmed a $27 billion gap in this year's defence financing, out of an estimated $155 billion total war cost. Roughly $7 billion is to be closed through austerity and reallocation, while the remaining $20 billion is the subject of talks with international partners. Prime Minister Serhiy Koretsky said the partner portion is critical to Ukraine's ability to fight in the first quarter of 2027 and to pre-pay for long-range weapons production.
Key points
- Defence budget deficit for 2026: $27 billion, out of an estimated $155 billion total war financing need.
- About $7 billion to be covered domestically through savings, optimisation and postponement of non-priority spending.
- Remaining $20 billion is the subject of negotiations with international partners.
- Prime Minister Koretsky says the $20 billion is critical to active combat operations in Q1 2027 and to paying in advance for long-range weapons production.
- Ukraine risks losing $29.5 billion in additional international financing if it fails to meet commitments by October 15, including laws to be voted by the Verkhovna Rada, Ukraine's parliament.
- The $155 billion total includes both budget financing and off-budget in-kind partner assistance such as PAC-2 and PAC-3 missiles, launchers and aircraft.
- MP Serhiy Rakhmanin said he could not confirm the precise $27 billion figure and described the gap as a matter of underfunding rather than debt.
Why it matters
The $27 billion gap is the central fiscal challenge of Ukraine's war effort. Failure to close it could affect payments to soldiers, disrupt the pre-financing of long-range weapons, and constrain active combat operations into the first quarter of 2027. The $20 billion the government is asking from partners is also linked to wider risks: Ukraine stands to lose an additional $29.5 billion in international financing if it does not meet specified commitments by mid-October, including adopting the laws the Verkhovna Rada, Ukraine's parliament, still needs to pass. Closing the gap domestically requires a 'strict regime' of austerity, including suspension of cultural programmes and postponement of infrastructure projects under the 'Resilience Plans'.
What happened
Ukraine's government confirmed a $27 billion deficit in this year's defence financing. Roughly $7 billion is to be covered through savings, optimisation and reallocation of expenditures, including postponement of non-priority spending, with the freed funds directed to payments to military personnel and support for their families. The remaining $20 billion is the subject of negotiations with international partners. Prime Minister Serhiy Koretsky told journalists that the $20 billion is critical to Ukraine's ability to conduct active combat operations in the first quarter of 2027 and to pay in advance for the production of long-range weapons, including the capacity to 'bring the war back to where it came from'. He described the $7 billion domestic effort as a 'strict regime of state finance austerity'. The government is working with the Verkhovna Rada to hold a session on 12 October to vote on draft laws needed to unlock the financing, with the broader commitments due by 15 October. Ukraine has asked the European Commission to bring forward the second tranche of EU support planned for next year, called on the EU to use frozen Russian assets to cover 2027 needs, and is pursuing new 'Drone Deals' with partners.
Where reporting differs
MP Serhiy Rakhmanin, a member of the Verkhovna Rada's national security, defence and intelligence committee, said he does not have a precise figure for the defence budget deficit and cannot confirm or deny the $27 billion cited by President Zelensky and Prime Minister Koretsky. He characterised the gap as more a matter of underfunding than debt, and pointed to what he described as 'not entirely careful' handling of the defence budget by the previous leadership of the Ministry of Defence. President Zelensky, Prime Minister Koretsky and other government statements affirm the $27 billion figure. Forbes Ukraine's analytical unit estimates the 2026 general-fund defence budget deficit can be reduced to $6–8 billion through reallocation from other budget items.
Background
Ukraine's total war-related financial needs for 2026 are estimated at $155 billion, a figure that combines budget financing and off-budget material-technical assistance from partners — weapons such as PAC-2 and PAC-3 missiles for Patriot systems, launchers and aircraft provided in-kind rather than as cash. The figure was first presented to partners at the Ramstein-format meeting in February 2026 by the then-leadership of the Ministry of Defence and was reaffirmed in the 'Financial Strategy' document the government submitted to the EU in March 2026 as part of negotiations over the Ukraine Support Loan, a 90 billion euro concessional loan Ukraine is negotiating with the EU. President Zelensky first cited the $27 billion figure publicly on 24 August during a meeting of the 'Coalition of the Willing', specifying that $8–10 billion is needed for weapons procurement for January–February 2027, including air-defence assets. Rakhmanin noted that the official defence budget, excluding the Czech Initiative and the Danish Model, is 4.4 trillion hryvnias, and that war-related spending grows by 15–20% each year, driven in part by strikes on defence-industry facilities, rising component costs and mobilisation. The IMF cannot finance military needs, and Ukraine has asked the European Commission to bring forward the second tranche of EU support originally planned for next year. Ukraine has also called on the EU to use frozen Russian assets to cover financial and military needs in 2027, and President Zelensky has said Ukraine expects €30 billion in European funds to be directed to defence.
