French financial markets and sovereign debt have entered a period of significant volatility driven by fiscal and political uncertainty. The CAC 40 index has declined, with major banks such as Societe Generale, BNP Paribas, and Credit Agricole experiencing notable share price drops. Specifically, Societe Generale shares fell by 4.1%, while BNP Paribas and Credit Agricole dropped by 3.4% and 3.5%, respectively.

Investor concern is centered on France’s high fiscal deficit and the political instability surrounding the 2027 presidential elections. The lack of a clear parliamentary majority complicates the passage of the 2027 budget, while populist economic proposals—including suggestions to cancel French debt—have increased nervousness regarding the country’s long-term economic direction. Political tension is expected to intensify as polls suggest potential matchups between radical left leader Jean-Luc Mélenchon and far-right leader Marine Le Pen.

This shift in sentiment has caused French borrowing costs to rise, leading to a situation where France has surpassed Italy as a primary source of concern for European government bond investors. While Italy has gained confidence through fiscal tightening and a decreasing debt-to-GDP ratio, France faces a widening fiscal deficit exceeding 5% of GDP. Consequently, the yield on Italian 10-year BTPs has fallen below that of French government bonds (Oats). As economic conditions deteriorate, market participants are monitoring Fitch, which is scheduled to re-evaluate France's A+ credit rating.
