Euro slides as French fiscal worries grip markets

On Monday, the euro plummeted to a 17-month low of $1.1161 as France's fiscal concerns gripped markets. This downturn in the euro was exacerbated by a surge in bond market volatility, which stoked worries of contagion risks across the region. The single currency had been on a four-week decline, slipping four times in a row. French debt levels and uncertainty surrounding the upcoming 2027 elections intensified the market's apprehension.

Brent Donnelly, president of foreign exchange trading at Spectra Markets, noted that the French politics trade has now reached a boiling point due to the imminent election. The euro's decline was also influenced by the aftermath of last week's bond market rout, which led to multi-decade high global borrowing costs and a sharp drop in French debt.

The US 10-year Treasury note yield was 5.262 percent, a slight relief following a recent 24-year high. Sterling and the Japanese yen also faced downward pressure, while the dollar index rose 0.47 percent to 102.37. Analysts anticipate that if interest rate volatility persists, it could further strain carry trades, cyclical currencies, and the euro, while safe-haven assets like the Swiss franc and the dollar might retain their appeal.
