Global financial services mergers and acquisitions (M&A) maintained their upward momentum in 2025, with total transaction value surging roughly 40% year-on-year to hit $499 billion. According to data from McKinsey & Co., global deal volume remained virtually flat, tracking 612 transactions in 2025 relative to 605 in 2024.
This dramatic rise in total value was fueled primarily by a shift toward larger corporate combinations. The average transaction size jumped from $590 million in 2024 to $815 million in 2025, with mid-to-large tier deals valued between $1 billion and $10 billion commanding more than half of the year’s total market value.
The financial technology (fintech) sector served as a primary engine for this dealmaking resurgence. Fintech recorded 55 transactions in 2025, generating a total deal value of $64 billion—a staggering 108% increase over 2024. This spike was accompanied by a 131% year-on-year surge in average fintech deal value, which climbed to approximately $1.2 billion, driven largely by massive consolidation within the payments space. Traditional banking institutions also aggressively pursued targeted technology acquisitions to upgrade legacy infrastructure and broaden their digital product suites. Notable examples included Banca Ifis acquiring Illimity in January 2025, followed by Allica Bank’s purchase of Kriya’s embedded finance platform in October 2025.
This sustained turnaround follows a sharp downturn in global financial services M&A in 2023. Enhanced banking profitability and an elevated interest rate environment materially strengthened corporate balance sheets, laying the groundwork for strategic, large-scale acquisitions. Despite banks pulling in a combined $1.2 trillion in net income in 2024—outperforming all other macroeconomic sectors—the banking industry continued to trade at a compressed average price-to-book value of roughly 0.9 times. Because numerous banks continue to hold substantial excess capital reserves, this persistent valuation gap could fuel additional M&A deal flow throughout 2026, especially among financial institutions prioritizing scale, technological modernization, and market share consolidation.
