Tulsa Teachers Credit Union (TTCU) has agreed to an $8.5 million class action settlement involving overdraft and non-sufficient funds (NSF) fees assessed on checking accounts. These fees are common across banks and credit unions and typically arise when transactions exceed an account’s available balance or when payments are returned unpaid. The settlement covers current and former TTCU checking account holders who were charged overdraft or NSF fees during the period from August 31, 2015 to May 1, 2024, reflecting a decade in which consumer scrutiny of “surprise” or allegedly unfair fee practices intensified across the retail banking industry. The lawsuit was filed because plaintiffs alleged TTCU’s fee practices improperly charged members in certain situations—claims often seen in similar cases involving “authorized positive, settled negative” debit card transactions, multiple NSF fees on the same item after repeated re-presentments, or transaction-posting methods that can increase the likelihood of overdrafts. While TTCU’s settlement is not an admission of wrongdoing, it is significant because it provides monetary relief to affected members and signals continuing pressure on financial institutions to ensure fee disclosures, account agreements, and posting practices match what consumers reasonably understand. The case fits within a broader national wave of overdraft/NSF class actions and regulatory attention from agencies such as the CFPB, with institutions responding by revising fee policies, limiting repeat NSF charges, enhancing real-time balance information, and tightening compliance with federal rules like the Truth in Savings Act and Electronic Fund Transfer Act requirements around clear disclosures and consumer authorization for certain overdraft services.
