They would've had to go to 0%. As cormacrelf mentions, short-term treasuries in 2021 were yielding < 0.1%. That's a pretty hard sell when inflation is running 8-9%.
Some banks did exactly that. Even now, when SVB is advertising 4.5% rates on business checking [1], First Republic Bank is offering 0.01% on Business Interest Checking [2]. But note that SVB's failure impacts all sorts of household names like Roku, Roblox, Coinbase, Stripe, while FRB reports that tech is only 4% of their business. Companies that don't offer yield lose out to companies that do in the yield-chasing competitive marketplace.
We're observing some form of anti-survivorship bias, where risky behavior was incentivized by the market, so market participants had to engage or get pushed out of the market, and so now we hear about the risky behavior because that's what failed. We're not talking about banks like FRB or Wells Fargo that offer 0% on their bank accounts.
