What bankers expect from bank M&A this year

Banks are expected to increase M&A activity due to favorable regulations, with Bain predicting a fifth $1 trillion asset bank by 2029. Santander's CEO plans a deliberate integration of its Webster Financial acquisition. M&A boosted noninterest income for large banks in 2025, and mid-size regional banks grew deposits by 8% through mergers. Large deals are now closing faster due to regulatory changes.
