As the pricing of the Federal Reserve's interest rate cut continues to escalate, investors are increasing their short selling efforts in the US dollar. Exchange data shows that the net short position size of US dollar index derivatives has increased by over 150% in the past week. Multiple institutions predict that the US dollar will further weaken next year. For money fund investors benefiting from high interest rates this year, the interest rate reduction may affect the yield of related products, trigger the readjustment of asset portfolio allocation, and the stock market and long-term treasury bond bonds may become important options.
