KUALA LUMPUR, Sept. 19 (Xinhua) -- S&P Global Ratings on Friday affirmed its "A-" long-term and "A-2" short-term foreign currency sovereign credit ratings on Malaysia. The rating agency said in a statement that it also affirmed its "A" long-term and "A-1" short-term local currency ratings for the country. The outlook on the long-term ratings is stable, and the transfer and convertibility assessment remains "A+," it said. "The stable outlook reflects our expectation that Malaysia's growth momentum and prevailing policy environment will allow modest improvements in fiscal performance over the next two to three years," said S&P. It noted Malaysia's consistently strong economic growth and high degree of monetary policy flexibility underpin its ratings.
