The deal party hit the brakes
Global mergers and acquisitions didn’t vanish, but they definitely stopped acting like there was an open bar. According to LSEG, M&A volume in the last three months came in at $993 billion, down 41% from the second quarter of 2026.
That matters because deal volume is often the market’s mood ring. When companies are eager to buy, it usually means confidence is high and financing is relatively friendly. When the rush fades, it can mean the exact opposite: borrowing costs are making CEOs and bankers think twice.
Why investors should care
Higher borrowing costs are the villain in this episode. Buying a company with cheap debt is one thing; buying it when money costs more starts to look a lot less glamorous. That can slow down:
- private equity exits
- mega-mergers
- debt-funded buyouts
- advisory fees for banks that live off transaction flow
The bigger signal
This was the first quarter to fall below $1 trillion since the second quarter of 2025, which is a pretty big psychological line in the sand. Not because $1 trillion is magic, but because Wall Street loves round numbers almost as much as it loves bonuses.
If dealmaking stays soft, that can ripple through investment banks, law firms, consultants, and the broader “let’s restructure the world” ecosystem.
Big picture: when financing gets expensive, even ambitious CEOs start acting like they’ve seen the credit card bill.
