FDIC Opens the Door to US Bank Mergers, Unlocking a Landmark M&A Deal

The US Federal Deposit Insurance Corporation, or FDIC, proposed revisions to bank merger rules in mid-September 2026 to unblock a bottleneck that had left mid-sized regional banks with assets between 10 billion and 50 billion dollars waiting more than a year for review. The new proposal rests on four pillars: expediting small de minimis transactions to completion within five business days; setting a timeline of no more than 90 days for mid-sized banks; revising the competition calculation to include credit unions and digital deposits instead of the old branch-based deposit concentration test under the Bank Merger Act; and limiting the use of arbitrary discretion to delay transactions based on meritless complaints. The revision comes alongside a Bain & Company report forecasting that the structure of the US banking industry will be radically transformed by 2030, with the number of mega banks holding more than 1 trillion dollars in assets rising from four to five to seven, while the number of regional and community banks nationwide falls significantly. The main drivers are the enormous cost of developing artificial intelligence and cloud systems, heavier regulatory compliance burdens, and demand for low-cost deposit sources, as well as the excess capital held by many financial institutions that is ready to keep driving acquisition deals forward.
