Mumbaikars started queueing up as early as 6 AM in the morning, nearly 3-4 hours before the banks open.
Several bank officials said most of the branches were witnessing unprecedented huge rush and therefore, they have sought the deployment of police personnel to deter any unwarranted circumstances.
The customers, however, seemed frustrated with some banks exchanging only Rs 2,000 with Rs 100 notes.
Clarifying on the issue, an executive of the bank said, "We are facing liquidity crisis. As and when the RBI supplies us sufficient notes we would start disbursing the notes with full permissible limit".

He also said that they have opened additional counters and cancelled the leaves of the staff to meet the demands.
Some customers who approached post office branches were seen displeased as they were unable to exchange the now defunct currency notes.
Some people were also miffed with the exchange limit of Rs 4,000.
Venting out her disappointment, Pramodini Naik, a housewife, said, "It seems we have to spend five to six hours daily for one month or two months to exchange the notes. This is really disgusting. Banning black money is ok, but certainly not this way".
Meanwhile, some banks issued SMS on cell phones to inform their customers regarding the process to be followed to deposit the notes.
