A rally that made European defence stocks one of the biggest equity trades of recent years has gone into reverse. The reversal comes as higher government borrowing costs and changes in warfare weigh on the sector.
Investor sentiment has soured as rising sovereign debt yields pressure the fiscal capacity of European governments to sustain elevated defence spending. Simultaneously, technological shifts—including the growing role of drones, cyber warfare, and AI—are challenging the traditional cost-plus contracting model that benefited legacy defence primes.
The selloff has hit a broad swath of European defence names, with the Stoxx Europe Aerospace & Defense Index declining after a sustained period of outperformance. The reversal marks a stark contrast from the sector's prior momentum, which was fueled by geopolitical tensions and pledges to boost military budgets.
Analysts caution that the correction could deepen if bond yields continue to climb or if procurement priorities shift further toward asymmetric capabilities. However, some investors view the pullback as a buying opportunity, arguing that baseline defence spending remains structurally higher than pre-2022 levels.
