We can see (short term) past weekly auction rate results for T-Bills of various duration, but wondering if it makes sense to wait until an upcoming expected increase is made official to yield the best short term rate? If so, the day after or about a week after for things to "catch up/adjust"? Or, are the rates currently "priced in" with the expected increase, hence doesn't really make a difference?
It would be easier to answer by myself if I could find historical data that I could cross against rate hikes/decreases to see average results on rates, but was unsuccessful.
Thanks!
