U.S. banks reported a record 24,454 suspected cases of elder financial abuse to the Treasury Department last year, more than double the amount five years earlier, according to government data.

The increase occurred as new federal and state laws are prompting banks to take a more active role in trying to address frauds and scams that target older customers. For their part, banks are beefing up training programs for employees on how to detect, stop and report issues without violating a customer’s privacy. Employees are even learning to recognize early signs of cognitive decline.

The issue of elder financial abuse is likely to grow even more pronounced. An average of 10,000 Americans turn 65 a day, a pace expected to continue through 2030. In that year, one in every five people will be 65 or older, according to the U.S. Census Bureau.

Meanwhile, people over 50 represent one-third of the population but account for 61% of bank accounts and 70% of bank deposits, according to 2017 research by the American Bankers Association.

“Anything having to do with elder financial abuse or exploitation affects a huge part of our customer base,” said Rob Rowe, associate chief counsel at the American Bankers Association.
