    The Swiss Franc rose in early Monday trading as US-Israeli strikes on Iran drove demand for safer assets. EUR/CHF fell to about 0.9030, the lowest since 2015, then rebounded to near 0.9110 after the Swiss National Bank said it was “increasingly prepared” to intervene. The Franc weakened against the US Dollar, with USD/CHF up 1.25% to about 0.7780, and it later lost ground against other major currencies by the end of the US session. The SNB policy rate is 0%, inflation is near zero, and the bank forecasts 0.3% average inflation for 2026. Swiss data were weaker, with January real retail sales down 1.1% year-on-year versus 2.7% expected, after 2.8% in December. February SVME PMI was 47.4 versus 50 forecast, down from 48.8. Markets expect Wednesday’s February CPI at 0.4% month-on-month and -0.1% year-on-year. USD/CHF was at 0.7789, with resistance near 0.7830 and 0.7900, and support around 0.7730 and 0.7625. The Franc is among the top ten traded currencies and was pegged to the Euro from 2011 to 2015; removal of the peg led to a rise of more than 20%. Some models put EUR-CHF correlation at more than 90%, and the SNB meets four times a year with an inflation aim below 2%. As we see it today on March 3rd, 2026, the Swiss Franc is caught between a geopolitical safe-haven bid and a central bank determined to weaken it. The US dollar is winning the safe-haven battle, primarily due to its significant yield advantage with a Federal Funds Rate near 3% compared to the Swiss National Bank’s (SNB) 0% rate. This interest rate difference is a powerful force that should continue to support USD/CHF. The SNB’s strong warning about being “increasingly prepared” to intervene is the most important factor right now. The combination of falling retail sales, a contracting manufacturing sector, and the risk of deflation from this week’s CPI data puts immense pressure on the central bank to act. We have seen this playbook before, as the SNB has a long history of massive currency interventions to prevent the franc from getting too strong. For derivatives traders, this suggests the 0.9000-0.9100 range in EUR/CHF is a line in the sand that the central bank will likely defend vigorously. This could make selling out-of-the-money puts on EUR/CHF an attractive strategy for collecting premium, betting that SNB action will limit further downside. The recent sharp plunge and quick recovery show the market is already pricing in this intervention risk. Looking at USD/CHF, the fundamental picture now clashes with the recent bearish technical trend. Given the SNB’s dovish stance and the attractive US yields, buying call options on USD/CHF could be a good way to position for a potential breakout above the 0.7830 and 0.7900 resistance levels. A deflationary CPI print this Wednesday would be the catalyst needed to fuel such a move higher. The weak economic data from Switzerland cannot be ignored and supports the case for a weaker franc. The PMI reading of 47.4 signals a deeper manufacturing contraction than we saw for much of the 2023 slowdown, reinforcing the SNB’s need to avoid a strong currency harming exports further. This weak domestic backdrop makes it very difficult for the franc to sustain strength on its own merits.
