Ahhhhh, the unintended consequences of gubermint meddling in the economy. No return on savings = no savings (or find another place to invest)...this will hurt the banks long-term because it dries up the reserves they need to make loans. I already cashed in my CDs...it wasn’t even paying enough to offset the risk of bank failure.
There are other ways to build capital, but in the O-conomy it is a very slow and laborious process.
Paying higher rates on savings hurts financial institutions through them having to pay for a higher cost of funds. That's why you will find savings on the debit side of a financial institution's ledger, not the asset side.
