Alloa will lose its TSB branch later this year.
36 branches across the country are set to close.
TSB say it's due to a lack of customers using branches - with 96% of transactions taking place outside of a branch.
Around 250 jobs are to be lost when the sites close in September.
Clackmannanshire and Dunblane MSP Keith Brown said:
"I am both shocked and appalled at the news that the TSB branch in Alloa is to close.
This will leave one bank in Alloa.
Closing it will mean that Alloa town centre is left with only two cash machines which will be concerning for those people who rely on cash.
Many businesses and residents will have moved to TSB in good faith when the other banks shut, and in my view, TSB should rethink this decision.
There are other cash machines in Alloa - at Tesco and Asda - but that takes people out of the town centre, and stops people spending cash in local businesses.
That’s before mentioning the impact that this closure will have on those employed at the branch.
Alloa went without a Post Office for a good amount of time, and this caused a number of issues - so local people and businesses will have some reservations about relying on banking services here.
I have previously tried to push the idea of a banking hub for Alloa town centre, as they have in Carluke - a centre which offers a Post Office, personal & business banking and bill payments for multiple banks, all under one roof. I think this could be a workable solution for Alloa.
I’ll be writing to TSB, and urging them to look again at this decision."
A TSB spokesperson said:
"Our priority is to consult with impacted colleagues to ensure they're fully supported, maximising redeployment opportunities where we can."
"We remain committed to a national branch network and through innovation and integration with video, telephone, digital, branch and other face-to-face services TSB customers have more ways to bank with us than ever before."
