India's finance minister tried to allay fears on Tuesday after media reports of shortages at ATMs across several states sparked memories of the chaotic scenes two years ago following the government's shock demonetisation move.
Local media reported from a string of central, eastern and southern states showing people queuing up at empty ATMs or complaining about a lack of notes.
"Have reviewed the currency situation in the country. Overall there is more than adequate currency in circulation and also available with the banks," Finance Minister Arun Jaitley said on Twitter.
"The temporary shortage caused by 'sudden and unusual increase' in some areas is being tackled quickly," he added, without elaborating on what might have caused the sudden increase in demand for notes.
The reports of cash shortages come at a sensitive time for the government of Prime Minister Narendra Modi with the annual harvest season and a crunch local election in southern Karnataka state coming up.
The country last saw such shortages in wake of Modi's shock decision to withdraw almost 86% of the cash in circulation with a single order in November 2016.
The move was a bid to clamp down on corruption and wipe out illicit or untaxed wealth, a move that had significant popular support.
But Indians were also forced to queue for hours to exchange their suddenly worthless bills with the poor struggling to buy daily essentials.
Many economists later linked job losses across many sectors to this decision.
Modi's opponents have latched on to the latest reports of cash shortages, questioning his government's handling of the economy.
"Seeing reports of ATMs running out of cash in several states. Big notes missing. Reminder of Demonetisation days," Mamata Banerjee, the firebrand chief minister of eastern West Bengal state said on Twitter.
"Is there a financial emergency going on in the country? #cashcrunch #cashlessATMs," she added.
India's finance ministry said that it had "adequate reserves" to meet the "extraordinary demand" of currency notes.
"The government would also like to assure that it would be supplying adequate currency notes to meet even higher levels of demand if such demand were to continue in the coming days/months," it said in a statement.
