The Federal Reserve's sudden decision to cut interest rates marked a major turning point in U.S. financial policy and also attracted widespread attention in the global currency circle. This interest rate cut is not only decisive and significant, but also a one-time reduction of 50 basis points, indicating that the U.S. economy is facing unprecedented pressure. The market generally interprets that the United States has officially "surrendered" to economic difficulties, and the smoke of the financial war seems to have temporarily dissipated. However, there is a deeper consideration hidden behind the interest rate cut - the U.S. economic situation is far more severe than it appears, and it may no longer be able to sustain it until next year's election. This move is not only a direct response to the domestic economic crisis, but also indicates that the global financial landscape is about to usher in a new round of turmoil. For the currency circle, the recession in the U.S. economy may generate new demand for safe havens, further promoting the status of cryptocurrencies as safe haven assets.
