The holidays will disrupt financial transactions in the stock markets, normal commercial deals, export shipments, import consignments and salary payments, Assocham said.
It said that March 28 is holiday on account of Ram Nawami followed by Sunday. The banks open on March 30 for a day for public and would be out of reach for the general public on March 31 and April 1 due to annual closing.
"From March 28 till April 6, the banking transactions are going to be affected," it said.
"We would urge the Reserve Bank of India (RBI) to step in and advise the banks to make some arrangements. With the government being the majority owners of the public sector banks, the Finance Ministry should also prevail on the bank managements to avoid this kind of huge customer inconvenience and widespread disruption to the business environment," Assocham Secretary General Mr D S Rawat said in a statement.
