Uneducated guess: this is not a pure financial crisis. This crisis results from the expectation that the virus is going to slow down the economy and businesses across all sectors/countries.

Movements of capital are expected to slow down as people stay home, lose their jobs, consume less... Hence why crypto (broadly described as currencies not controlled by central banks), used to transact, dived as well.

This said, I would advise you not to worry (perhaps accumulate even), as I do not expect banks to do well in such an economic downturn. The trust in financial institutions that keeps the people from going all-in on crypto will erode in due time.
