according to data provided by Crane Data, which has long been researching the currency market fund field, as of the week of November 13th, the management assets of US currency market funds increased by about $91 billion, and the total scale exceeded $7 trillion for the first time, which is a milestone for the industry. Due to the high and reliable yield, the popularity of this industry among investors has risen sharply. Before reaching the $7 trillion mark, the scale of US currency market assets hit a historic high for several consecutive months, which refuted doubts about whether the industry could continue to be popular as Federal Reserve officials lowered interest rates from their highest level in 20 years. After US policy makers cut interest rates by 50 basis points in September and another 25 basis points this month, investors continued to pour into currency market funds, mainly because the yield of these funds is higher than other tools, especially bank deposits. Compared with banks, the speed at which these funds transmit the impact of low interest rates is often slower.
