HSBC is to close 69 branches across the UK, affecting around 400 staff, as customers shift to online and mobile banking.
The lender said that fewer than 50% of the its customers now actively use its branch network, with the average footfall declining over 50% since 2017.
HSBC said the shift towards online and mobile banking had accelerated since the start of the pandemic.
It follows the announcement in January last year of 82 branch closures for similar reasons.
HSBC said that it hoped to redeploy staff affected by the latest announcements to other roles within the bank.
The lender will be left with 441 UK branches after the closures, it said.
