Europe has allocated only €4.2 billion in new military aid to Ukraine through October 2025, placing the continent on track for its lowest annual aid allocation since Russia's full-scale invasion in February 2022, according to the latest Ukraine Support Tracker update from the Kiel Institute published December 10. The allocation rate represents a dramatic slowdown from the record-high levels recorded in the first half of 2025 and falls far short of offsetting the halt in US military support under the Trump administration. At current monthly rates, total 2025 allocations will significantly undershoot the €41.6 billion annual average maintained across 2022–2024.
The data underscores a dual crisis in European support architecture: widening disparities among major donors, and institutional paralysis over the financial mechanisms designed to sustain multi-year aid. As diplomatic efforts intensify—including recent talks in Berlin hosted by German Chancellor Friedrich Merz with US envoys—Europe's capacity to backstop Ukraine's defense hinges on whether member states can resolve legal constraints on frozen Russian assets and reverse the allocation decline before 2026 budget cycles lock in.
Allocation collapse follows summer spike
After peaking in early 2025 on the strength of several large procurement packages, European military aid commitments fell sharply over the summer and continued to decline through September and October. The Kiel Institute data shows that to match the 2022–2024 average, Europe would need to allocate an additional €9.1 billion by year-end—a monthly rate more than twice the pace observed in recent months. The slowdown coincides with the US shift toward increased arms sales and constraints on drawdown authority packages, leaving a capability gap that European industry and budgets have proven unable to fill at speed.
The trajectory matters not only for Ukraine's near-term battlefield sustainability—particularly air defense and artillery munitions—but also as a test of European strategic autonomy rhetoric. Berlin talks between Merz, US presidential envoy Steve Witkoff, and senior advisor Jared Kushner took place against Merz's public warning that "Pax Americana" is largely over, reinforcing the burden-shift pressure. Yet institutional constraints and diverging risk appetites among member states have stalled the very instruments intended to stabilize long-term support.
Burden-sharing gap widens within Europe
Disparities among European donors have grown sharper in 2025. Germany nearly tripled its average monthly allocation versus the 2022–2024 baseline, while France and the United Kingdom more than doubled their contributions. Germany leads cumulative European military aid with €16.5 billion as of mid-2025; the UK had committed €9.4 billion by August 2024. Yet measured relative to GDP—the metric that captures fiscal effort—all three major economies still lag the Nordic donors: Denmark, Finland, Norway, and Sweden continue to outpace larger states in per-capita terms, according to Kiel Institute researchers Christoph Trebesch and Arianna Nishikawa.
At the other end of the spectrum, Italy reduced already modest allocation levels by approximately 15 percent compared to the 2022–2024 average, while Spain recorded no new military aid commitments in 2025. The bifurcation reflects diverging threat perceptions, domestic budget pressures, and differing industrial capacities, but the aggregate effect is clear: a handful of states are carrying a disproportionate share of the continent's security investment.

What comes next
Ukraine faces a dual timeline: diplomatic efforts around security guarantees—President Volodymyr Zelensky recently signaled openness to binding guarantees in lieu of immediate NATO membership—and the material reality of continued Russian drone and missile campaigns against energy infrastructure. Europe's capacity to underwrite the latter depends on decisions in the coming weeks. Key variables include whether the European Council can agree on indemnification structures that unlock the broader frozen-assets loan, whether the EPF receives another substantial top-up before year-end, and whether monthly allocation rates rebound in the final quarter of 2025.
National budget cycles for 2026 will lock in much of the answer. If current trends hold, Europe will enter the new year with its lowest new military aid allocation since the invasion, widening intra-European burden-sharing disparities, and a frozen-assets mechanism stalled by unresolved legal exposure. The data from Kiel offers a clear benchmark: Europe must more than double its recent monthly allocation rate simply to match prior-year averages, let alone compensate for the US withdrawal. Whether institutional caution or strategic urgency prevails will define European security policy for the next phase of the conflict.
