AlQa'dah 05, 1436, August 20, 2015, SPA -- Malaysian Prime Minister Najib Razak said on Thursday he would not peg the ringgit to the U.S. dollar or implement capital controls as he sought to calm fears about the sliding currency and capital flight from Southeast Asia's third-largest economy, Reuters reported. "The flexibility of our exchange rate is important to absorb global adjustments and volatility," Najib said in a statement. The ringgit, Asia's worst performer this year with losses exceeding 17 percent against the dollar, was steady on Thursday after the comments and found some respite as China's yuan rallied.
