Czech National Bank brief links higher European defense spending to short term output gains, inflation after two to three years

The Czech National Bank published a research brief examining the macroeconomic and financial effects of Europe’s post-2022 rearmament. Based on a panel of 28 European countries, it finds that higher defense spending is associated with a quick increase in output, while inflationary pressures emerge with a lag of about two to three years. The brief also finds that the inflation effect is uneven across countries, with earlier and stronger price pressures where defense equipment is produced domestically and weaker near-term effects where procurement relies more on imports. The analysis places these findings in the context of a sharp rise in European military expenditure since 2022, led increasingly by equipment procurement rather than personnel spending and occurring as defense demand appears to be outpacing production capacity. A one-standard-deviation increase in defense spending relative to GDP, about 0.12 percentage point, is associated with roughly a 0.5 percentage point rise in GDP growth in the first year and a similar increase in inflation by the third year. For the Czech Republic, which the brief describes as combining a relatively strong domestic defense industry with a significant import component, the inflation effects are likely to be moderate and gradual relative to countries with predominantly domestic production. The brief also notes that financial markets moved ahead of budgets, with global defense stock valuations more than doubling to EUR 3.5 trillion by 2026-Q1 and Czech household holdings of defense stocks rising from EUR 94 million at end-2021 to EUR 635 million by 2026-Q1, indicating active net purchases rather than valuation gains alone.
