How much would loosening German borrowing limits boost growth?
Core argument: German borrowing costs rose by the most since 1997 after Friedrich Merz and the Social Democrats agreed to exempt defence spending above 1% of GDP from the constitutional borrowing limit and create a €500bn off-balance sheet infrastructure vehicle.
Chancellor-in-waiting Friedrich Merz agreed with the rival Social Democrats to exempt defence spending above 1% of GDP from Germany’s strict constitutional borrowing limit, set up a €500bn off-balance sheet vehicle for debt-funded infrastructure investment and loosen debt rules for states. Deutsche Bank economists described the deal as “one of the most historic paradigm shifts in German postwar history”, adding that both the “speed at which this is happening and the magnitude of the prospective fiscal expansion is reminiscent of German reunification”. Analysts at Goldman Sachs said the package could boost German economic growth to as much as 2% next year — up from the bank’s current forecast of 0.8% — if it is approved and implemented quickly. The euro rose 0.7% against the dollar to $1.070, its highest since November, and German stocks surged. Europe’s defence sector extended a blistering rally. Shares in Rheinmetall, Germany’s largest defence company, were up 7.2% while Paris-listed Thales rose 7.6%.
