After suspending interest rate hikes in September, the Federal Reserve's next move will affect the sensitive nerves of the market. Recently, Federal Reserve Chairman Powell stated that the inflation level in the United States is still too high and will retain the option of further interest rate hikes. Since March last year, the Federal Reserve has raised the target range of the federal funds rate from near zero to between 5.25% and 5.5%. Economists from many countries believe that the high interest rate policy of the United States has led to the soaring yield of US treasury bond bonds and the strengthening of the US dollar, resulting in capital outflows, high inflation, currency devaluation, rising financing costs, and even the risk of debt default in many countries and regions, seriously dragging down the recovery of the world economy.
