MUMBAI: If you were greeted by empty automatic teller machines (ATMs) over the past few days, it is not because there is cash shortage only in your locality: the whole country is facing cash crunch once again, reminding people of the post-demonetisation days.About 60% of the ATM machines are working, but most of them are running out of cash very fast as they are not being loaded to their full capacity, sources said, adding that though cash supply had improved at the turn of the new year, it had not gone up significantly.According to industry insiders, ATMs are not being filled to the maximum capacity of around Rs 30 lakh because of insufficient cash supply. In fact, only Rs 10 lakh is being loaded in each machine."We are still loading less than 70% of the full capacity of ATMs and there are concerns around the (inadequate) supply of Rs 100 denomination notes," said the chief executive of one of India's big gest ATM manufacturing companies, which also manages ATMs.According to experts, cash withdrawals are usually very high towards the end of a financial year, which might have added to the scarcity."Every year we usually see a spike in supply of currency notes to meet this higher demand. The demand this year has been high as usual, but there was no increase in supply, causing a serious cash shortfall across the country ," said another top executive with a cash logistics company responsible for transporting cash and managing ATMs. "Usually we see about 35% of the entire cash supply for the month of March happening in the fourth week. But that much cash was not supplied this year," he said.
