SNB's Schlegel says U.S. tariffs present 'major challenge' to economy

ZURICH, Sept 25 (Reuters) - U.S. tariffs are a "major challenge" and will likely dampen economy activity, Swiss National Bank Chairman Martin Schlegel said on Thursday after the central bank held its interest rates at 0%.

"Against this backdrop, our monetary policy is supporting economic development, " said Schlegel, in remarks prepared for a press conference, although he noted uncertainty currently remained high.
