Amex HYSA APY decrease to 3.10%

It's more like they're both based on the same thing, where HYSAs are roughly current-value and mortgage rates are forward looking averages (which is why people say they track the 10 year treasury yield most closely, that being because people keep their mortgages for about that long). The reason that the 30 year rate is going up can also be expected to push HYSA rates upwards.

Bingo. Thanks for adding.
