What will happen to bank deposits if stablecoins pay interest?

It's quite obvious that banks aren't very popular among their own customers. And yet banking is essential for the current system to sustain itself. It's something like the circular system of the planet. This is undoubtedly because banks aren't doing their basic job: taking money from depositors in exchange for a certain return and lending in exchange for higher returns, taking a small commission. Instead, their greed leads them to charge high rates to some and not remunerate the deposits of others. Perhaps this is due to the reserve requirement, which allows banks to manipulate the market, or perhaps it's due to the near-zero-cost loans provided by central banks.

Lately, I've read many articles discussing the potential impact of stablecoins on passive returns for their holders. In fact, this is what USDT does by buying US Treasury bonds, but it keeps the profits for itself. Some of these articles discuss central banks' fear of a run on or capital flight from commercial banks. Customers would seek returns if they have confidence in these stablecoins. But that could lead to a financial collapse of the system.
Do you think this could happen? Have you withdrawn significant fiat currency from your bank?
