I agree the Fed definitely screwed up and should have started raising rates last year, or at least began cutting back their bond purchases much earlier, but they felt supply chain issues would repair themselves throughout 2021. But then delta hit and caused supply problems all over again through the middle of 2021, and then omicron wave caused more problems in late 2021.
So they felt inflation would ease by itself, which was wrong, so they concentrated more on their other mandate for full employment, so they wanted to stay at zero until it was still not back to pre-pandemic levels.
Now they realize supply chains will take longer than expected to repair, especially with some of Covid waves currently hitting Asia, so they can only try to affect the other side of the equation by slowing down demand by raising rates.
I doubt it will have much effect either way, supply chain is the primary problem and higher rates won't help with that.
It's funny reading earnings reports the last few weeks, where every CEO has mentioned not getting pushback from customers from their price hikes, they just keep buying at increasing levels. Which is so weird since according to this board everyone in the country is doing terrible right now.
