According to Jinshi, on March 22, the RMB exchange rate fell, breaking through the consolidation range that had lasted for nearly two months. Guo Yiming, investment advisory director of Jufeng Investment Consulting, said that this week is the "Super Central Bank Week", and changes in the monetary policies of global central banks may have a certain impact on the market. After the Swiss National Bank unexpectedly cut interest rates and the Federal Reserve hinted at three interest rate cuts this year, the U.S. dollar index recorded its largest one-day rise in more than a month, which may have an impact on the RMB exchange rate. Fan Ruoying, a researcher at the Bank of China Research Institute, said that the main reason for the decline in the RMB exchange rate was the rise in the US dollar index. Since the beginning of this year, the U.S. dollar index has maintained a high operating trend overall, non-U.S. currencies such as the pound have depreciated against the U.S. dollar, and the overall performance of the RMB exchange rate has been stable.
