Ukraine’s Defense Budget Gap Has Reached $27 Billion: Why Europe Wants the New Need Explained

When European leaders and officials arrived in Kyiv for Independence Day, they heard a figure many had not expected. President Volodymyr Zelensky said Ukraine would be short roughly $27 billion for defense needs by the end of 2026, despite the massive external financing that had already been agreed.

Zelensky explained the gap by saying that the Defense Ministry had used part of the resources earlier in the year that, under the budget plan, were supposed to be spent much later. In effect, future money was pulled forward to pay more quickly for urgent military needs.

That is fundamentally different from a situation in which the state suddenly created $27 billion in entirely new spending. A significant part of the problem is about timing: the war forced Ukraine to pay for weapons and operations earlier than the budget calendar anticipated, while the revenues meant to offset those costs remained tied to later dates.

At the same time, there is still no full public breakdown of the entire amount. Zelensky has referred to weapons, military pay and support for the families of those killed in action, but the government has not published a table that would allow an outside observer to add up every component and arrive at exactly $27 billion.

Daycom’s analysis indicates that the absence of such a transparent calculation helps explain the nervous reaction among some European partners. The issue is not that Ukraine is spending heavily on the war — no serious actor disputes that. The question is why such a large deficit became apparent so late and how it fits with resources that had already been approved.

The scale of Ukraine’s military spending has indeed risen sharply. From January through July 2026, general-fund spending on security and defense reached UAH 1.63 trillion, almost 20% more than during the same period a year earlier. The sector accounted for more than 63% of all general-fund expenditure.

In June, the Verkhovna Rada had already carried out a huge budget revision. Funding for the security and defense sector was increased by UAH 1.56 trillion, bringing the annual total to UAH 4.367 trillion. Of the additional amount, UAH 174.3 billion went to personnel payments and UAH 1.371 trillion to weapons, equipment, ammunition and repairs.

That means the current $27 billion gap appeared after one of the largest wartime revisions of the defense budget. That is precisely what makes Kyiv’s request so important for its partners: it shows how quickly the actual needs of the front can outrun even very large budget decisions.

Part of the explanation lies on the battlefield. Russia is increasing the production and use of strike drones and missiles, while Ukraine is forced to expand interceptor systems, domestic drone production, long-range capabilities, ammunition stocks and component purchases. The government openly acknowledges that the cost of sustaining the war is rising.

Air defense is becoming especially expensive. Kyiv is simultaneously trying to obtain more U.S.-made interceptors, expand domestic production and sign weapons contracts years in advance. The shift from short-term purchases to large, long-term contracts alone creates the need for substantial advance payments today.

A second factor is the structure of military spending itself. Soldiers’ salaries, compensation to the families of those killed and payments related to injuries cannot simply be postponed to the next quarter. In early September, the government separately reallocated UAH 33.6 billion for such needs, including UAH 25.9 billion for military pay in September.

That is why discussions about budget austerity quickly collide with political and military reality. Ukraine can cut some administrative programs, delay civilian investment or search for additional revenues. But a soldier’s salary, ammunition for a unit or compensation to the family of someone killed in action is not an ordinary budget item that can easily be deferred.

There is also a third problem: the war is increasing expenditure while simultaneously damaging the sources of revenue. Russian attacks on businesses, energy infrastructure, ports and transport networks reduce production and exports precisely when the state needs to collect ever more taxes to finance defense.

The result is a double pressure. Moscow spends resources to force Ukraine to spend more on protection while at the same time attacking the economic assets that help finance that protection. For a wartime budget, this is one of the most dangerous forms of attrition: the cost of defense rises faster than the fiscal base.

Against this backdrop, the dispute surrounding former Defense Minister Mykhailo Fedorov has also become a dispute over responsibility for the $27 billion figure. Zelensky linked the deficit to the decision under the ministry’s previous leadership to pull future spending forward. Fedorov has firmly denied that he left behind a gap of that scale.

According to Fedorov, the projected deficit during his tenure was significantly smaller, and his team expected to offset it through procurement savings and international assistance. He suggested that new projects may have appeared later or that the financial plan may have changed. That makes the origin of the full amount a political dispute as well as an accounting one.

The public argument is particularly sensitive because of the circumstances of Fedorov’s departure. His removal from the Defense Ministry in July triggered protests, while military management had already become part of domestic political debate. Responsibility for financial planning has now been added to the conflict over strategy and reform.

For Europe, the dispute has arrived at an awkward moment. In April, the EU formally approved a €90 billion loan for Ukraine covering 2026 and 2027. Roughly €30 billion was designated for budget support and €60 billion for the defense sector and procurement.

For 2026, €45 billion from that package was expected to be made available. Of that amount, €16.7 billion was to go to budget support and €28.3 billion to Ukraine’s defense-industrial capabilities. The remainder of the overall loan was scheduled for 2027.

As of Sept. 7, the European Commission said €11.6 billion had already been disbursed from the new instrument and that further tranches were expected in the coming weeks. Brussels has stressed that its current objective is to deliver the agreed €45 billion in financing this year.

That points to the most obvious immediate option: give Ukraine some of the money intended for 2027 earlier. Kyiv is asking for so-called frontloading — accelerating payments from the already approved loan. Politically, that is easier than creating an entirely new European package within a matter of months.

But there is no financial magic in the mechanism. If money planned for 2027 is spent in the autumn of 2026, the present gap can be reduced, but fewer resources will remain for next year. If the war continues at its current intensity, Europe will simply encounter the same problem sooner.

That is why the $27 billion question is turning into a debate not about one tranche, but about the cost of the war in 2027. The government is already discussing with the IMF and the European Commission how to assess needs over the next two years and prepare a balanced budget for the coming year.

In practical terms, Ukraine’s partners need to understand whether the current shortfall is a one-off consequence of accelerated procurement or whether it signals a new, permanently higher level of Ukrainian military spending. In the latter case, shifting money between years would only postpone the need for much larger financial decisions.

Another potential source remains frozen Russian assets. Roughly €210 billion in assets belonging to the Russian central bank are immobilized in the European Union. Ukraine currently benefits mainly from the income generated by those assets rather than from confiscation of the principal itself.

Kyiv argues that this is not enough. Ukrainian officials are again pushing the idea of using the Russian funds themselves, or cash balances linked to them, as the basis for much larger financing. For a country spending enormous sums to repel Russia’s invasion, the political logic of such an approach is straightforward.

The idea has never fully disappeared inside the EU. At the end of 2025, the European Council instructed officials to continue legal and technical work on a possible reparations loan linked to Russian assets. But there is still not enough political support to implement such a model.

The strongest concerns involve legal risk, possible litigation and the consequences for confidence in Europe’s financial system. That is why the EU learned far more quickly how to use profits generated by frozen assets than it has been willing to touch the underlying principal.

This means Russian assets are unlikely to close Ukraine’s financing need within the next few weeks. Even if political support grows, the mechanism would require complicated legal decisions. For an autumn shortfall, the faster route remains accelerating programs that already exist.

Ukraine is also appealing not only to the EU, but to Britain, Canada, Japan and other partners. That matters especially as the United States steps back from directly financing Kyiv: the less Washington assumes, the larger the share of the cost of Ukraine’s defense that falls on Europe and other allies.

For European governments, that is politically harder than it was during the first years of the full-scale war. Every additional billion for Ukraine now competes with spending on national armed forces, social programs, infrastructure and debt servicing. Even governments firmly committed to Kyiv must explain those choices to their own voters.

The demand for a detailed answer to the question “why exactly $27 billion?” therefore does not necessarily signal weakening support for Ukraine. It also reflects the war’s transition into a different financial phase. When assistance is measured in tens of billions every year, allies will inevitably demand more precise forecasts, budgets and oversight mechanisms.

For Kyiv, that creates an uncomfortable balance. A forecast that is too optimistic risks producing another unexpected deficit. A request that is too large in advance may trigger suspicion that needs are being overstated. And war makes every precise projection provisional, because one new form of Russian attack can change the structure of spending within months.

That is why the budget story of 2026 goes far beyond accounting. Ukraine is gradually moving from a model in which partners cover individual emergency needs to one of financing a prolonged major European war, where the annual requirement for tens of billions becomes structural.

For Europe, this is also a moment of choice. If the continent assumes Ukraine must continue defending itself regardless of how long the war lasts, financing will have to be built not as a sequence of crisis packages, but as a predictable multi-year system linked to weapons production, the state budget and Russian assets.

Such a system, however, will require greater financial transparency from Ukraine. Partners will want to see not only the headline figure, but how much is required for personnel, procurement, domestic production, imports, air defense, long-term contracts and which expenses can be deferred without creating a direct risk to the front.

The $27 billion figure therefore matters not only because of its size. It has shown how quickly the financial reality of the war can overwhelm a plan that only months earlier appeared both massive and sufficient.

Ukraine now has to persuade Europe not simply to provide more money, but to accept the calculation of what the war now costs.

And Europe has to decide whether it is prepared to finance that cost not for a few more months, but for as long as the war requires.
