There are banks & credit unions that pay interest close to the fed funds rate. Unfortunately just not the mainstream consumer banks.
Some examples:
Goldman Sachs (1.90%): https://www.marcus.com/us/en/savings/high-yield-savings
Ally Bank (1.85%): https://www.ally.com/bank/view-rates/
Alliant Credit Union (1.80%): https://www.alliantcreditunion.org/rates
