European military aid to Ukraine has experienced a significant decline over the summer months, according to a report from the Kiel Institute for the World Economy. In July and August, European nations collectively contributed or earmarked approximately 3.3 billion euros (around $3.8 billion) for military assistance, averaging 1.65 billion euros monthly. This marks a staggering 57 percent decrease from the first half of the year, during which 3.85 billion euros (approximately $4.5 billion) were allocated monthly.
The downward trend is not isolated to European contributions; overall military aid from all nations has fallen by 43 percent during the same period, which coincided with the announcement of a substantial aid package from Canada at the end of August.
Christoph Trebesch, head of the Ukraine Support Tracker and Research Director at the Kiel Institute, observed that Europe appears to be reducing its overall military support for Ukraine. Looking ahead, he noted the importance of monitoring aid levels as autumn approaches, suggesting that developments in the coming months will be critical.
A significant portion of the military supplies delivered this summer was facilitated through NATO’s Prioritized Ukraine Requirements List (PURL), a mechanism initiated by former U.S. President Donald Trump and NATO Secretary General Mark Rutte. This program allows NATO countries to purchase U.S. defense systems and munitions from American stockpiles, which are then dispatched directly to Ukraine. This process is designed to expedite support and minimize wait times for critical armaments.
By the end of August, eight NATO member countries—Belgium, Canada, Denmark, Germany, Latvia, the Netherlands, Norway, and Sweden—had engaged with the PURL, contributing a total of 1.9 billion euros (about $2.2 billion) in military assistance.
Overall, European nations, including the United Kingdom, have provided or earmarked a total of 83 billion euros ($96.5 billion) in military aid to Ukraine since the onset of the Russian invasion in February 2022, surpassing the 64.6 billion euros ($75.1 billion) allocated by the United States.
The U.S. had previously been the leading provider of aid to Ukraine until the transition in leadership in January 2025, which saw Trump deviate from the support strategies established under his Democratic predecessor, Joe Biden.
In contrast to military aid, financial and humanitarian assistance has remained stable, with 7.5 billion euros ($8.7 billion) provided, despite a lack of new contributions from the U.S. Trebesch emphasized the need for this stability to extend to military support, highlighting Ukraine’s reliance on sustained assistance to maintain its defense efforts against ongoing aggression.
