It's been a decent year for banks, especially given the industry's return on assets hit a 10-year high. But there are signs it might not last. With Halloween near, here is a look at some potentially frightening developments that could keep bankers up at night.

Cybersecurity and breach notification procedures have caught the most public attention following the massive hack at Equifax, but lawmakers are also interested in the accuracy of credit reports.

Congress may soon try to limit the personal identifiable information that companies and the government can collect on consumers based on their reaction to the massive data breach at Equifax.

Wells Fargo CEO Tim Sloan took heat from Senate Democrats, who questioned his fitness for the job, the bank's use of mandatory arbitration clauses and even whether its charter should be revoked.

Sen. Elizabeth Warren, D-Mass., is broadening her probe into the data breach to look at whether the company should have disclosed the breach sooner and if it plans to claw back compensation.
