Switzerland's SNB sharply reduces foreign currency purchases in third quarter

ZURICH, Dec 31 (Reuters) - The Swiss National Bank bought 75 million Swiss francs' ($95 million) worth of foreign currencies in the third quarter of 2025, ?a sharp reduction from the previous three-month period, data from ?the central bank showed on Wednesday.

During the second quarter, ?the SNB bought 5.06 billion francs' worth ?of foreign ?currencies as economic uncertainty stirred by U.S. trade policy piled appreciation ?pressure on the safe-haven Swiss ?franc.

U.S. President Donald Trump unveiled a raft of tariffs against trade partners in ?the second quarter, and ?the ?value of foreign currencies purchased by the SNB in that period was the highest quarterly total in ?more than three years.

In August, Trump imposed 39% tariffs on Switzerland. A deal to reduce those levies was not reached until November.

The franc has appreciated by almost 15% against the ?dollar this ?year, according to LSEG data. Against the euro, however, it has only gained slightly. The ?bulk of Switzerland's foreign trade is with euro zone countries.

Buying foreign currencies can help the SNB contain the appreciation of the franc. A rapid strengthening of the franc can put downward pressure on import costs.

The SNB ?targets annual inflation of 0-2% and the rate is currently right at the bottom end of that range.
