The Swiss National Bank kept its key policy rate unchanged at 0% on Thursday, signaling continued caution amid lingering global uncertainties from the Iran conflict, while explicitly reaffirming its willingness to intervene in currency markets to prevent disruptive appreciation of the safe-haven franc.
The decision, widely anticipated by markets, leaves Swiss borrowing costs significantly below those in other major economies and reflects the central bank’s delicate balancing act between low domestic inflation and external pressures. In his remarks, SNB Governing Board Chairman Martin Schlegel highlighted how the outbreak of hostilities on February 28 initially drove investors toward the franc, though that safe-haven demand has since moderated.
“As the interest rate differentials with other countries have widened, the Swiss franc has depreciated somewhat. However, the geopolitical situation remains uncertain. The risk of strong upward pressure thus persists,” Schlegel said.

The central bank stands prepared to act against any “rapid and excessive appreciation” of the franc, which could harm Switzerland’s export-oriented economy. This readiness echoes the SNB’s historical approach to currency management, where interventions have occasionally drawn international criticism.
Inflation in Switzerland rose to 0.6% in May from 0.1% in February, driven primarily by higher energy prices linked to disruptions from the Middle East conflict. While this marks a noticeable uptick, it remains modest by global standards. The SNB assessed that medium-term inflationary pressures had stayed largely stable, giving it room to maintain its accommodative stance for now.
Diverging Global Policy Paths
The decision comes as other central banks shift toward tighter policy. The European Central Bank raised its key rate by a quarter-point to 2.25% in its latest move, aiming to counter inflation risks from elevated energy costs. The U.S. Federal Reserve held its benchmark rate steady at 3.5%-3.75% this week but signaled potential hikes later in the year as it monitors the fallout from the conflict.
These widening interest rate differentials have contributed to some recent softening in the franc. Yet Schlegel emphasized that the geopolitical backdrop keeps the risk of renewed safe-haven flows alive. A stronger franc would make Swiss goods more expensive abroad, potentially weighing on the country’s manufacturing and export sectors, which are vital to its economy.
Swiss economic activity has held up better than expected during the conflict, with the SNB now forecasting growth of around 1% for 2026 and 1.5% the following year. Still, the central bank warned that the primary risks to this outlook stem from the broader global environment, particularly U.S. trade policies and ongoing Middle East uncertainties.
“If necessary, we therefore have an increased willingness to intervene in the foreign exchange market. Uncertainty about inflation and economic development is still high. We will therefore continue to monitor the situation and adjust our monetary policy if necessary, to ensure appropriate monetary conditions,” the bank said.
Tensions with Washington
Economists expect any renewed intervention to put the SNB on a collision course with Washington. Last year, the U.S. Treasury Department placed Switzerland on its monitoring list for currency practices, reviving accusations from President Donald Trump’s first term that Bern manipulates its currency to gain trade advantages.
The U.S. subsequently imposed a 39% tariff on Swiss goods, one of the highest applied to any nation, citing both currency issues and trade barriers. Swiss officials have consistently rejected those claims.
Trump has previously criticized the SNB’s currency strategy, and fresh interventions could reignite those tensions at a delicate moment in international economic relations. The SNB’s careful wording on Thursday appears designed to signal resolve without provoking immediate backlash.
Switzerland’s economy, long known for its stability and financial sophistication, faces a unique set of challenges. As a small, open economy heavily reliant on exports, it is particularly sensitive to currency swings. At the same time, its safe-haven status, amplified during periods of global stress like the current Middle East conflict, can create appreciation pressures that run counter to domestic needs.
By holding rates at zero while keeping intervention options on the table, the SNB is attempting to thread a narrow needle: supporting growth and price stability at home while guarding against excessive franc strength that could undermine competitiveness. The central bank’s assessment that medium-term inflation risks remain contained gives it flexibility, but the unpredictable nature of geopolitical developments means policy could shift quickly if conditions change.
