Many European countries have decided to significantly increase their military spending, led by Germany. Will this effort be conducive to growth? This will depend on whether or not Europe is able to increase its production of military equipment. It will also depend on the possible crowding-out effects (inflation, interest rates) associated with an increase in public debt. The ability of European industry to meet demand (an increase in EU military spending from 2% to 3.5% of GDP) will be decisive. A reallocation of currently underutilised production capacity (mainly in the automotive and intermediate goods sectors) could help to increase production.
