The Consumer Financial Protection Bureau is suing Capital One for allegedly misleading customers about its high-yield savings account options and cheating them out of close to $2 billion in interest.

The bank misled its customers after promising a new savings account with a higher interest rate not already provided to existing accounts, regulators said.

In response, Capital One said that it strongly disagreed with the CFPB’s allegations and plans to “vigorously defend” itself in court. The banking giant added that it was “deeply disappointed to see the CFPB continue its recent pattern of filing eleventh-hour lawsuits ahead of a change in administration.”
