French bond contagion fears are rattling the euro

The euro has been sliding to its lowest level in 17 months, triggering concerns among policymakers about rising borrowing costs in France that are spreading to the broader eurozone. Investors are dumping French bonds in favor of safe German debt, leading to a widening yield gap between the two countries. This has sparked fears of "contagion" in the euro area, where political uncertainty and inflation are already putting pressure on the currency.

The French government is seeking to pass an unpopular 2027 budget to reduce its deficit and debt, a difficult task in a politically divided parliament ahead of next year's presidential election. The situation is further complicated by elections in Spain and Italy next year. With inflation driven by energy costs and higher yields increasing borrowing costs, the European Central Bank faces a delicate balancing act between fighting inflation and calming bond markets.

The spread between French and German 10-year bond yields has hit its highest level in decades, while the gap between Italian and German yields has reached almost 130 basis points. This has led to a broader sell-off in euro-denominated assets, with the euro falling against major currencies including the dollar, yen, and Swiss franc.

Analysts warn that tighter fiscal coordination and measures to stabilize markets will be crucial if the fiscal contagion risk is not contained.
