ZURICH, March 19 (Reuters) - The Swiss National Bank has increased its willingness to intervene in foreign exchange markets to counter the rapid appreciation of the Swiss franc since the start of the Middle East conflict, Chairman Martin Schlegel said on Thursday.
"A rapid and excessive appreciation of the Swiss franc poses a risk to price stability," said Schlegel after the SNB's latest interest rate decision.
"To counter this risk, our willingness to intervene in the foreign exchange markets has increased," he added.
