Six Dumfries and Galloway branches of the Bank of Scotland are set to close by March 2026.
Lloyds Banking Group has announced it will close nearly 150 branches of Lloyds, Halifax and Bank of Scotland over the next couple of years.
And among them are the Annan, Moffat, Thornhill and Sanquhar outlets of Bank of Scotland.
The firm had already announced the Newton Stewart and Langholm branches were to close over the next few months.
That will leave just three Bank of Scotlands in the region – in Dumfries, Castle Douglas and Stranraer – although banking hubs are proposed for Annan and Langholm.
A spokeswoman for Lloyds Banking Group said: “Over 20 million customers are using our apps for on-demand access to their money and customers have more choice and flexibility than ever for their day-to-day banking.
“Alongside our apps, customers can also use telephone banking, visit a community banker or use any Halifax, Lloyds or Bank of Scotland branch, giving access to many more branches.
“Customers can also do their everyday banking at over 11,000 branches of the Post Office or in a banking hub.”
The Langholm branch is due to close on April 7, with the Newton Stewart branch closing on June 25.
Newton Stewart could be home to a new banking hub, where people can use banking services regardless of who their account is with.

Cash machine operator LINK is also looking into the possibility of a hub in Annan, where Bank of Scotland is pencilled in to close on March 2, 2026.
The Sanquhar branch is due to close on May 28 this year, with Moffat on October 29 and Thornhill on November 3.
Dumfriesshire MP, David Mundell, said: “This news will come as an extremely heavy blow to the communities which stand to be affected and are, in effect, evidence of the Bank of Scotland giving up on providing traditional banking services in rural communities.
“The effect of these closures, if they are followed through, will be profound and will leave several of the communities without any easily accessible bank branches whatsoever, particularly impacting older residents and those without private means of transport.
“I will be seeking to raise this with Ministers at the earliest opportunity and believe the Bank of Scotland must now examine each of those communities which stand to be stripped of their high street branches with a view to providing banking hubs within them.”
