The Swiss National Bank stepped into the foreign‑exchange market in Q1, selling Swiss franc to curb a sharp rally triggered by the outbreak of hostilities in the Middle East. When the US and Israel launched attacks on Iran, investors scrambled for the franc’s perceived safe‑haven status, pushing the currency higher. The move also underscored the fragility of safe‑haven flows when conflict spikes.

By flooding the market with franc supply, the SNB aimed to prevent a disruptive appreciation that could hurt exporters and inflate the domestic price index. A stronger franc typically squeezes Swiss‑based manufacturers, whose margins are already pressured by global supply‑chain strains, while also raising the cost of foreign‑denominated debt held by banks. Analysts warn a sustained rally could tighten monetary conditions.

The intervention signals that the central bank will not tolerate excessive currency moves amid geopolitical risk, reinforcing its commitment to monetary stability. Market participants will watch forthcoming SNB policy minutes for clues on the duration of the sell‑off, as any reversal could reignite franc buying pressure. Investors should therefore calibrate currency exposure as the SNB readies its next rate decision.
