European defense stocks plummeted on Friday after news broke of a planned summit to address the Ukraine conflict. This sector, which has thrived in 2025 due to rising geopolitical tensions and boosted defense budgets, faced a sudden setback.
On Thursday, U.S. President Donald Trump spoke with Russian President Vladimir Putin for two hours.
Trump called the talk productive, and they agreed to meet in Budapest within two weeks to discuss Ukraine. This sparked hopes for peace but also uncertainty among investors.
Defense Index Takes a Hit
By 8:52 AM GMT, a key aerospace and defense index dropped 3.4%. It hit its lowest level in over a month, marking the biggest one-day fall since July. Investors grew cautious, fearing a diplomatic resolution could reduce demand for defense products.
Since Russia invaded Ukraine in February 2022, the defense index has soared by over 200%. European governments have poured funds into security, driving this growth.
What Analysts Are Saying
Stephan Maichl, an analyst at Landesbank Baden-Wuerttemberg, said, “The upcoming Trump-Putin summit in Budapest has renewed hopes for peace in Ukraine.
Investors are playing it safe, but if the talks fail, we could see a quick reversal, like after the Alaska summit.” His comments highlight the defense sector’s volatility.
Defense stocks have helped lift the STOXX 600 index by 13% in 2025, hitting record highs. Expectations of ongoing military spending have fueled this rise.
Major Companies Feel the Impact
Friday was tough for top defense firms. Germany’s Rheinmetall, Hensoldt, and Renk each fell about 6%. Italy’s Leonardo and Sweden’s Saab dropped around 4.5%. BAE Systems, Europe’s largest defense company by market value, lost 3.4%.
These drops show how sensitive the market is to geopolitical shifts. Investors worry that successful talks could slow defense spending, though many doubt a quick resolution.
What’s Next for Defense Stocks?
The sell-off reveals how defense stocks react to changes in global politics. The Budapest summit could ease tensions, but past talks have often failed to deliver lasting results.
This suggests investor caution may be short-lived. For now, the defense sector remains vital to European markets, but its future depends on the outcome of these high-stakes talks.
