July 15 (Reuters) - Morgan Stanley ( MS ) beat Wall Street estimates for second-quarter profit on Wednesday, driven by strong mergers and acquisitions activity, while macroeconomic uncertainty resulted in record trading revenue at the investment bank.

A lenient regulatory environment and buoyant equity markets have helped company executives across sectors to pursue large-scale deals, generating a windfall in advisory fees for investment banks.

Mega-deals helped drive the total value of announced mergers and acquisitions to $2.8 trillion in the first six months of the year, up 48% from a year ago and marking the highest first-half total since LSEG records began in 1980.

Among the notable deals in the quarter, the bank acted as a financial advisor on Fertitta Entertainment's agreement to buy Caesars Entertainment in a deal valued at $17.6 billion.

Morgan Stanley ( MS ) served as a lead underwriter for the record $2 trillion market debut of Elon Musk's SpaceX, a landmark initial public offering that was a part of the revival of activity in U.S. listings market.

The investment bank was a lead underwriter on chipmaker Cerebras' stellar New York IPO and a joint book-running manager on Alphabet's equity capital raise announced last month.

JPMorgan Chase, Bank of America and Goldman Sachs ( GS ) - who were also part of the bookrunning syndicate for the landmark SpaceX IPO - reported a similar jump in investment banking on Tuesday.

Morgan Stanley's ( MS ) investment banking revenue soared to $2.44 billion from $1.54 billion a year ago, boosted by a rise in M&A advisory fees.

Net income applicable to the investment bank came in at $5.58 billion, or $3.46 per share, in the three months ended June 30, compared with $3.54 billion, or $2.13 per share, a year earlier.

Analysts were expecting ​a profit of $2.94 per share, according to data compiled by LSEG.

WEALTH MANAGEMENT RECORD

Morgan Stanley's ( MS ) wealth management revenue rose to a record $8.9 billion in the quarter, up from $7.8 billion a year ago, solidifying the bank's reliance on the unit to offset potential volatility in its trading and investment banking businesses.

The bank cited the performance in the unit to strong asset management fees, robust client activity and higher net interest income.

Total client assets across wealth and investment management hit a record $10 trillion in the second quarter, reaching a major target the bank set several years ago.

Net revenue came in at $21.35 billion in the three months ended on June 30, compared to $16.79 billion in the year earlier.

Analysts were expecting a revenue of $19.64 billion in the second quarter.

TRADING REMAINS STRONG

Global markets navigated significant turbulence during the quarter as the U.S.-Iran standoff triggered uncertainty over global crude supplies, resulting in a sharp rise in oil prices.

Persistently high inflation and shifting monetary policy expectations also injected more unpredictability, even though major equity benchmarks demonstrated robust resilience.

Such volatile conditions typically create a favorable environment for Wall Street's trading operations.

Clients executed a higher volume of transactions to hedge against risks and capitalize on pricing swings, boosting Morgan Stanley's ( MS ) trading desks. The portfolio reshuffling drove robust quarterly revenue gains across its trading division.

Equities revenue surged over 69% to $6.3 billion. Fixed Income net revenue rose 13%.

JPMorgan Chase, Bank of America and Goldman Sachs ( GS ) - who also beat quarterly profits on Tuesday - reported a similar jump in trading.

Morgan Stanley ( MS ) shares were up about 1% in trading before the bell. The investment bank's shares have gained 28.5% in 2026, underperforming Goldman Sachs ( GS ), but outpacing the benchmark S&P 500 index.
