Food is not included in the computation of inflation.
I read the FED reports. “Historical Norms” are never mentioned.
The FED says its job is too keep inflation at a target rate (currently 2%, which according to them is where we are at) and to keep the business cycle at “full” employment, which they also say we have reached.
If they keep raising they’ll just have to lower again when employment and inflation drop below their targets.
The only thing I can come up with is that they think the job market is too hot, and they know politically they can’t raise rates much once the presidential campaign really takes off. The 4th year of presidential terms usually sees a quiet FED. They can’t blame inflation, it’s right where they say they want it.
