Lebanese banks will remain shut "indefinitely" due to a lack of security protection by authorities, say their association, BBC reported.
The announcement by the Association of Lebanese Banks follows a string of raids by customers demanding access to frozen savings last week.
It said their employees faced risks which had not been mitigated.
A woman armed with a toy gun staged a hold-up at a bank on Wednesday to pay for family medical bills.
There have since been other copycat raids, with reports of at least five last Friday.
Lebanon is in a severe economic crisis, with more than 80% of the population struggling to afford food and medicine, according to BBC.
Banks have limited withdrawals of dollars since 2019, when the value of the Lebanese pound plummeted and inflation soared.
