Europe is increasing defence spending after decades of cuts, linked to the war in Ukraine, wider power rivalry, and uncertainty over US security support. Higher budgets can lift GDP in the short term by boosting demand through public purchases and hiring.
The spending acts like fiscal stimulus when governments recruit personnel, buy equipment, build facilities, and fund cyber capabilities. This can raise activity in industry and the labour market.
Medium Term Risks From Rapid Buildups
IMF research points to medium-term risks when defence outlays rise quickly and are financed through larger budget deficits. It also notes a risk of higher inflation and higher interest rates.
The IMF says defence build-ups can push prices up temporarily, especially when an economy is already near full capacity. These effects depend on multipliers, debt dynamics, and inflation conditions.
Some European governments are also seeking to expand domestic production of ammunition, AI, satellites, cyber defence, and other advanced technologies. This could shape industrial policy and influence longer-term productivity and competitiveness.
The ongoing rearmament in Europe is acting as a major fiscal stimulus, much as we saw during previous buildups. Germany just confirmed its defense budget will hit 2.5% of GDP this year, a trend echoed across the continent, with NATO’s European members collectively adding over $80 billion in new spending since early 2025. This government-led demand is directly boosting industrial output and employment figures.
Market Implications For Rates And Inflation
This spending is fueling the inflation that we have seen prove stubborn over the last year. April’s Eurozone CPI reading came in at 2.8%, higher than expected and driven by industrial input costs, raising concerns at the European Central Bank. This suggests the era of disinflation we experienced after the energy shock of the early 2020s is firmly behind us.
For traders, this points toward positioning for higher interest rates for longer. We should consider using interest rate swaps to hedge against rising rates or buying puts on long-dated government bond futures, like the German Bund. The market is now pricing in a 40% chance of an ECB rate hike by the fourth quarter, a sharp reversal from sentiment at the start of the year.
This environment is creating clear winners in the equity markets, particularly in defense and high-tech industrial sectors. The STOXX Europe Aerospace & Defence index is already up 18% year-to-date, extending the powerful rally we saw through all of 2025. This momentum suggests that buying call options or structuring bull call spreads on companies like Rheinmetall and BAE Systems remains a viable strategy.
The potential for sustained Eurozone inflation and corresponding central bank action could also lend strength to the Euro. Given the Federal Reserve is signaling a more neutral stance, long positions on the EUR/USD through futures or call options could offer upside. This trade benefits from the widening interest rate differential expectations between the ECB and its global peers.
Looking at volatility, the divergence between a strong growth outlook and the risk of rising interest rates is creating uncertainty. Implied volatility on the Euro Stoxx 50 remains elevated compared to historical averages for this point in the economic cycle. Buying calls on the VSTOXX index could be an effective way to protect portfolios from any sudden market shocks caused by hawkish policy surprises.
