Santander is going to close 140 of its UK branches - including in Monmouth.
More than 1200 jobs are at risk - but the bank says it hopes to offer new roles to around a third of those affected.
It has announced its Monmouth branch in Agincourt Square will close on 30th May.
The Spanish-owned company says it's making changes because more banking is done online and via apps.
Susan Allen, Santander's head of retail and business banking, said: "The way our customers are choosing to bank with us has changed dramatically in recent years, with more and more customers using online and mobile channels.
"As a result, we have had to take some very difficult decisions over our less-visited branches, and those where we have other branches in close proximity.
"We will support customers of closing branches to find alternative ways to bank with us that best suit their individual needs."
