European defence spending surge raises inflation and debt concerns

European nations are undergoing a significant period of rearmament, leading to substantial increases in defence spending that carry potential macroeconomic consequences. In the European Union, defence spending is projected to reach approximately €454 billion this year, a sharp rise compared to the €218 billion recorded in 2021.

European Central Bank Chief Economist Philip R. Lane has highlighted the risks this fiscal acceleration poses to inflation, debt, and monetary policy. While increased spending can provide a short-term boost to GDP, historical data suggests that sustained defence build-ups tend to widen fiscal deficits by an average of 2.6 percentage points of GDP and increase debt-to-GDP ratios by roughly 7 percentage points within three years.

In the United Kingdom, the government has committed to increasing defence spending to 2.5% of GDP by April 2027. This shift represents an end to the ‘peace dividend’ enjoyed after the Cold War, as resources are diverted from sectors such as healthcare, education, and infrastructure toward military capabilities.
