Every FOMC meeting, people watch the rate decision. Hold, cut, or hike. One number. It moves markets for a day.
The rate decision is the least informative thing the Fed releases.
Four times a year, the Fed also releases its Summary of Economic Projections. The SEP is the real signal. It is a window into what the committee actually believes about where the economy is heading and what policy path it thinks it needs to get inflation back to 2%.
Most people skip it. The people who read it carefully tend to see the market's next move before most others do.
