The Swiss franc on Thursday plunged to its lowest level so far this year after the Swiss National Bank said it was set to make purchases in the foreign exchange market to halt the currency’s rise.
The Swiss franc’s haven status has been heightened by the recent market turmoil and has helped the currency rise 9 per cent on a trade-weighted basis since July and come close to its record high around SFr1.43 against the euro in recent weeks.
