The Wall Street Journal writes "World’s Largest Money-Market Fund Will Lower Its Returns, Shed Risk," which says, "The manager of the world's largest money-market fund said it would take steps to reduce risk in its investments and lower the lofty yields that have helped draw a flood of cash into the fund over the past year. Tianhong Asset Management Co., a Beijing-based company that manages a money-market fund with more than $200 billion in assets, is making changes to comply with liquidity rules imposed recently by Chinese regulators, according to Wang Dengfeng, general manager of Tianhong's fixed-income department. "We will step up efforts to adhere to the original function of money-market funds as a cash management tool that carries low risk, low yield and high liquidity," Mr. Wang said in an interview with The Wall Street Journal. The result will be a gradual slide in the fund's investment yields, he added." The piece explains, "The giant fund, called Yu'e Bao, recently saw its seven-day investment yield top 4% on an annualized basis, up from 2.3% a year earlier. Its yield is in line with that of other Chinese money-market funds but dwarfs interest rates on short-term Chinese government debt and bank deposits, as well as returns on money-market funds in the U.S. and Europe."
