Under the auspices of “protecting clients from criminal activity,” JPMorgan Chase has decided to impose withdrawal limits on certain ATM transactions. As WSJ reports, following the bank's ATM modification to enable $100-bills to be dispensed with no limit, some customers started pulling out tens of thousands of dollars at a time. This apparent bank run has prompted Jamie Dimon to cap ATM withdrawals at $1,000 per card daily for non-customers.

Most large u.s. banks, including Chase, Bank of America Corp., Citigroup Inc. and Wells Fargo & Co. have been rolling out new ATMs, sometimes known as eATMs, which perform more services akin to tellers. That includes allowing customers to withdraw different dollar denominations than the usual $20, typically ranging from $1 to $100.

The efforts run counter to recent calls to phase out large bills such as the $100 bill or the €500 note ($569) to discourage corruption while putting up hurdles for tax evaders, terrorists, drug dealers and human traffickers.

The Wall Street Journal reported in February that the European Central Bank was considering eliminating its highest paper currency denomination, the €500 note. Former U.S. Treasury Secretary Lawrence H. Summers also has called for an agreement by monetary authorities to stop issuing notes worth more than $50 or $100.

This move appears to have backfired and created a ‘run' of sorts on Chase…

A funny thing happened as J.P. Morgan Chase & Co. modified its ATMs to dispense hundred-dollar bills with no limit: Some customers started pulling out tens of thousands of dollars at a time.

While it was changing to newer ATM technology, J.P. Morgan found that some customers of banks in countries such as Russia and Ukraine had used Chase ATMs to withdraw tens of thousands of dollars in a single day, people familiar with the situation said. Chase had instances of people withdrawing $20,000 in one transaction, they added.
