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.
