Liquidity crunch, probably as startups are drawing down cash to pay bills/payroll/interest payments… Trying to convert eg. long term treasuries held by the bank to cash for satisfying customer withdrawals takes time, and has costs. If too many customers attempt to do this in a short period of time, you start having to delay withdrawals, panic spreads and the process escalates and feeds back on itself.
