Perhaps they should try and introduce decentralization to all the financial institutions to avoid these recurring issues.
The sec is a centralized agency, how can they or the U.S government introduce decentralization. The decentralized options are available for persons and institutions to use, though the government and their centralized agencies do not like them.
The collapse of Silicon Valley bank and Signature bank is similar to what happens in centralized crypto exchanges, their users feel these institutions have reserves to cover a bank run or a massive withdrawal, but they do not, they function through a fractional reserve system, and what you see in your account, or address is just digits, as your money has been used for trading or to buy high or low risk assets. If whatever trade these institutions use your money for fails, then withdrawal is only possible for a few people, and the many who could not withdraw their money have to wait for a long and hopeless law proceeding.
