Asian Currencies Tumble Most in 21 Months on Fed Exit Outlook

Asian currencies tumbled by the most in 21 months this week as Federal Reserve Chairman Ben S. Bernanke said the central bank will probably taper stimulus that has fueled fund flows to emerging markets.

India’s rupee touched a record low and Malaysia’s ringgit had its worst week in three years after Bernanke said June 19 that $85 billion a month of debt purchases, known as quantitative easing, may be trimmed this year and ended in 2014 as long as the U.S. economy performs in line with Fed estimates.
