idk how many companies are doing this right now, but recurring investment on 4 week T-bills are safe, can absorb arbitrary amounts of cash, and yield much more than the large banks. But it can take a bit to set up a TreasuryDirect account.
Everyone and their mother aping into T-bills will also have the effect of lowering the rates on Treasuries, making 1.5% bonds a reasonable choice again.
