The United Forum of Bank Unions (UFBU), which represents nine trade unions, said they will also hold a three-day strike from March 11-13.
"From April 1, we have decided to go on an indefinite strike," UFBU state convenor Siddartha Khan told PTI.
UFBU is seeking at least a 15-per cent hike, but the IBA has capped the raise at 12.25 per cent, he said.
"This is not acceptable," Khan said.
The last wage revision meeting was held on January 13.
