On June 8, 2026, the National Credit Union Administration (NCUA) announced the adoption of an Interim Final Rule clarifying the authority of federal credit unions (FCUs) to impose non-interest charges and fees, including interchange fees associated with payment card transactions. The rule, which becomes effective on June 30, 2026, reinforces NCUA’s position that federal law exclusively governs FCUs’ authority to assess such fees and that state laws purporting to regulate those fees are preempted.
