Global investors are holding their breath for the "most unpredictable" Fed meeting in history:

Is it a 25 basis point or 50 basis point rate cut?

However, according to Ray Dalio, the founder of the world's largest hedge fund Bridgewater and a billionaire investor, the magnitude of the "first cut" is actually not that important. Judging from the overall situation of the US economy, the Fed may cut interest rates slightly this week, and the magnitude of 25 basis points is appropriate.

The "most unpredictable" in history, at present, the market generally expects the Fed to cut interest rates at this meeting, but there have been differences on the magnitude of the rate cut.

The CME Fed Observation Tool shows that the probability of a 50 basis point rate cut is as high as 61%, but there is also a 39% probability of a 25 basis point rate cut. This Fed meeting can be said to be the most unpredictable in history.

Analysts at investment company Deutsche Bank commented that the Fed's decision is likely to be "the biggest surprise in 15 years."
