Global M&A Financial Sector Grows H1 2026

Volume up, ticket size down

EY's latest financial-sector M&A readout frames the divergence cleanly. Banks, insurers, and asset managers announced 1,137 deals globally in H1 2026 against 1,101 a year earlier. Aggregate disclosed value, however, contracted from $191.3 billion to $134.5 billion — a direct function of far fewer $1B-plus transactions clearing.

Concentration metrics reinforce the signal. The top 10 deals in H1 2026 captured 58% of total value ($78.7 billion), identical in proportion to the 58% share booked by the top 10 in H1 2025 ($111.3 billion). Top 20 concentration actually rose to 75% from 72%. In absolute terms, average ticket at the top decile compressed to roughly $7.9 billion from $11.1 billion — a meaningfully thinner bid at the upper tail. Fewer megadeals at a fixed concentration share means the median deal moved further away from the summit, not closer to it.

European sub-sector stress points

Europe carried 375 of the global deals, a 7% YoY increase from 350. Aggregate disclosed value there fell from $74.9 billion to $63.9 billion.

Within Europe, the banking and capital-markets book is the weakest read: deal count slipped to 88 from 96, and aggregate value collapsed from $50.7 billion to $19.3 billion — a roughly 62% drawdown in transacted value against a single-digit decline in transaction count. Insurance ran the inverse on volume (146 to 153 deals) but saw disclosed value shrink from $21.6 billion to $13.4 billion. The translation: European bank M&A is still completing, but at materially smaller scale; insurance is doing more deals at compressed multiples.

What to track into H2

EY's Global Financial Services Leader Omar Ali characterizes the operating environment as volatility-baked-in, with slower global growth, persistent inflation, and supply disruption continuing to suppress ticket size. Boards, per his framing, are positioned to accelerate strategic execution in H2 — a setup worth monitoring for reactivation at the megadeal tier.

Practical watch list for allocators: megadeal count versus the H2 2025 baseline of 55; European bank deal-value recovery off the $19.3 billion trough; insurance check-size stabilization near the $13 billion mark. Until megadeal flow re-accelerates, mid-cap financial-sector M&A carries the volume, while the upper tail remains a thinner, harder-to-source pipeline — a structurally smaller alpha surface for dedicated dealflow strategies built around $1B-plus transactions.
