Most major currencies have weakened against the dollar since the end of last year. Comparing currencies on April 22nd, the biggest loser has been the Swiss franc, which has fallen by 8.4% this year. This was in part because of the intervention of the Swiss central bank in currency markets on March 12th to push the franc's value down. But the euro, the Korean won and the Swedish krona have also weakened by more than 6% against the dollar, and the yen has fallen by 7.6%. The Australian dollar, the Canadian dollar and Chinese yuan were almost steady.
