The Swiss National Bank (SNB) has repeatedly stated its increased willingness to intervene in foreign exchange markets, particularly since the Iran crisis in early 2026. This stance was adopted to combat the appreciation of the Swiss franc, which surged as investors sought safe haven assets amid geopolitical uncertainty. On March 2, 2026, the SNB issued a rare verbal intervention, threatening to act against gains in the franc as the impact from US action in the Middle East rippled around the world. The euro dropped to $0.9037 francs, its lowest level since 2015, prompting the SNB to signal its intention to check the strengthening franc to avoid negative inflation and protect Swiss exporters.
Analysts, such as UBS economist Alessandro Bee, expected the SNB to sell francs to slow its appreciation but did not anticipate the central bank defending a specific level, understanding that strong inflows could reverse quickly. ING Bank senior economist Charlotte de Montpellier suggested the SNB's statement, though a surprise, reflected its difficult situation and hoped it would impact the franc. She also noted that the US, which monitors Switzerland for currency manipulation, might be more tolerant of Swiss interventions given the crisis.
Even with a subsequent Middle East peace deal in discussion, the SNB maintained its hawkish posture. On June 18, 2026, policymakers, led by President Martin Schlegel, kept the interest rate at zero and reiterated their willingness to intervene "if necessary." Vice President Antoine Martin confirmed in an April television interview that the SNB maintains an elevated willingness to intervene, stating, "What we have seen since the start of the conflict in Iran is that the Swiss franc has fallen in value. So yes, we are concerned about the strength of the Swiss franc, we have said that we are prepared to take action."
The central bank's consistent message underscores its commitment to managing the franc's strength and mitigating the economic ramifications of geopolitical events. This strategy aims to ensure price stability in Switzerland and support the competitiveness of its export-oriented economy, without necessarily resorting to interest rate cuts or other emergency measures unless the situation indicates long-term structural problems rather than short-term geopolitical risk aversion.
