Is now a good time to make major financial investments given current market volatility?

Global M&A volumes totaled $993 billion in the third quarter of 2026, marking a 41% decline from the second quarter. This result pushed quarterly deal activity below $1 trillion for the first time since Q2 2025.

Why it matters

Rising bond yields and market volatility have created significant valuation uncertainty, discouraging buyers and sellers from completing transactions. Consequently, companies are adjusting their IPO plans as investors display increased selectivity regarding valuations.

Global M&A volume reached $993 billion in the third quarter, reflecting a 41% decrease from the prior period. This drop marks the first time quarterly volume has dipped below the $1 trillion threshold since the second quarter of 2025.

The players

Bank of America

This multinational investment bank and financial services holding company reported investment banking fee results that differed from the majority of other major U.S. banks during the quarter.

Holtec

This company is among the entities that chose to postpone its initial public offering due to current market conditions.

Oura

The technology firm decided to delay its initial public offering amid the broader market downturn.

SB Energy

This firm elected to delay the launch of its U.S. IPO roadshow as deal activity faced downward pressure.

The details

While investment banking fees rose for most major U.S. banks, firms like Bank of America reported results that diverged from this trend. Several companies, including Holtec, Oura, and SB Energy, have opted to postpone their IPO roadshows or public launches as market conditions remain unfavorable.

Q2 2025 marked the last period M&A volume remained below $1 trillion.
September 2026 saw a notable market slowdown for deal completions.
Q3 2026 total global M&A volume reached $993 billion.
Q4 2026 is expected to feature softer IPO activity.

Market Dynamics

The current downturn in merger activity represents a shift back to conditions last observed during the second quarter of 2025. This contraction highlights the impact of tightening monetary environments on long-term corporate deal cycles.

The slowdown in IPOs and deal flow suggests that retail investors may face fewer new public offerings in the coming months. Furthermore, continued high interest rates may influence future dividend policies and overall portfolio performance for those heavily invested in banking and industrial sectors.

The takeaway

The cooling IPO market highlights the importance of timing for companies looking to go public in a high-interest-rate environment. Investors should remain cautious as deal activity remains sensitive to volatility and borrowing costs through the end of the year.
