The euro fell to its weakest level in 17 months against the dollar on Monday, dropping below $1.12 as investors worried about France's debt burden and political instability across the eurozone.

The currency declined as much as 0.8% in early trading, marking its lowest point since May 2025, according to The Guardian. The euro has fallen about 1.2% this month alone and has lost roughly eight cents from its January peak of $1.20.

France's Cac 40 stock index also slid during the period. The Guardian cited growing concern about France's debt position as a threat to the wider single currency bloc. An announcement of a snap election in Spain added to eurozone uncertainty, the outlet reported.

The source material does not provide specific detail on the size of France's debt, recent policy announcements, borrowing costs, or the timeline and mechanics of the Spanish election. It does not name French or Spanish officials or explain what particular actions triggered the moves. The Guardian's attribution of the euro's decline to "growing concern" about French debt does not specify which investors are concerned, what threshold or trigger prompted the shift, or whether France's debt metrics have recently worsened or simply drawn fresh attention.

The absence of named sources, recent French fiscal data, or concrete political developments limits the depth of explanation for the currency move beyond the stated worry about debt and election uncertainty.
