SNB board member says negative rates still an option if needed

ZURICH, April 3 (Reuters) - The Swiss National Bank could introduce negative interest rates if necessary because the policy has worked in the past, though it would prefer to avoid it, governing board member Petra Tschudin said on Thursday.

Speaking at an event in Zurich, Tschudin said she was surprised by how high the U.S. import tariffs imposed by President Donald Trump on Switzerland were.
