The Swiss National Bank (SNB) has sent a clear signal that it's ready to step into the currency market to manage the Swiss franc's strength.
This move is driven by a classic chain of events. First, recent geopolitical tensions in the Middle East, specifically disruptions in the Strait of Hormuz, have made investors nervous. In times of uncertainty, they seek 'safe-haven assets', and the Swiss franc (CHF) is a prime example. This 'flight to safety' has led to a surge in demand for the franc, causing its value to appreciate against other currencies.
Second, this strengthening franc creates a major headache for the SNB because of Switzerland's extremely low inflation. With inflation already hovering near zero, a stronger currency makes imported goods cheaper. While that might sound good, it can push the overall price level down, raising the risk of deflation—a harmful economic condition where prices persistently fall. The SNB is keen to avoid this scenario.
Third, the SNB has limited options to respond. Its main policy interest rate has been at 0.00% since June 2025, meaning there's little room for further cuts to weaken the currency. This leaves direct FX intervention—selling Swiss francs to buy foreign currencies—as its most powerful and immediate tool to counteract excessive appreciation.
The SNB's recent warnings aren't coming out of nowhere. Throughout March, officials have been gradually 'hardening' their language, starting with an unusual unsolicited warning and culminating in Chairman Martin Schlegel's explicit statement. This consistent messaging makes their threat of intervention credible and actionable for market participants.
In short, the combination of an external shock (geopolitics) and specific domestic conditions (low inflation, zero rates) has pushed the SNB to a point where intervention to counter rapid CHF gains is not just possible, but highly probable.
