In the current situation, it is best to raise rates once and then hint at a freeze for the rest of the year

Personally, I think a freeze would be more appropriate,
but regardless of that, in the current market, it is better to raise them once as the market expects.
Otherwise, uncertainty may actually increase, and there is a high possibility of chaos arising from the politicization of the Fed and bond market volatility caused by inflation concerns.
So, if they raise rates once as the market desires, long-term Treasury yields will at least come down,
and at the same time, they can convey that the economy is strong, inflation from rising oil prices is temporary, and overall inflation is showing a slowing trend.
If the dot plot also points toward a freeze by year-end, I think that would be the best approach...
However, if they commit to a rate hike, it seems likely that the dot plot will show the possibility of another hike later this year.
