Swiss Franc Surges as French Fiscal Stress Spills Into FX Markets

EUR/CHF has recorded its biggest weekly decline since the April 2025 tariff shock as concerns around French politics and fiscal conditions weigh on the euro and drive demand for the Swiss franc.
The move is notable because Switzerland's policy rate remains at zero, suggesting investors are prioritizing perceived safety over yield. The currency move also shows stress in French bond markets spilling into foreign exchange.
A persistently strong franc could increase pressure on the Swiss National Bank, which has previously intervened in currency markets to limit excessive appreciation.
