Recent movements in financial markets suggest a subtle change in the market's anticipation of the Federal Reserve's actions in September. By analyzing US short-term interest rate futures contracts, market participants have observed a shift from a consensus expectation of a 25 basis point cut to a preference for a more aggressive move of 50 basis points. This transformation indicates a reassessment of the current economic environment and the direction of the Fed's policy. Amidst slowing global economic growth and increased uncertainty in domestic economic data, there is growing demand for the Fed to adopt a more lenient monetary policy to spur the economy. As a result, it is anticipated that within the next few weeks, the Fed will respond to these market expectations by implementing the corresponding rate cut measures.
