Banker Accidentally Leaks Internal Information. He Immediately Regrets It.

A Morgan Stanley employee accidentally leaked an internal list containing more than 100 potential deals the Wall Street giant was pitching and monitoring this week.

The document contained potential initial public offerings across China, South Korea and India, as well as information about private equity and pension funds backing companies and projects that had been put on hold, according to Bloomberg. The blunder highlighted the risks financial institutions face protecting closely guarded client and transaction information, even from mistakes made inside their own ranks.

Morgan Stanley’s Asia-Pacific head of financial sponsors, Mohamed Atmani, sent the internal list to clients before attempting to recall the email, according to the Financial Post. The document primarily covered Asia but also included deals involving Europe, the Middle East and Africa.

Morgan Stanley told Bloomberg that it takes client confidentiality “extremely seriously.”

“We promptly took steps to address this inadvertent sharing of information and we continue to engage with relevant parties,” the bank said.

Morgan Stanley paid more than $249 million in 2024 to resolve federal investigations involving the disclosure of confidential information surrounding block trades.

The Securities and Exchange Commission (SEC) charged Morgan Stanley in January 2024 with failing to enforce policies concerning the misuse of material nonpublic information after employees disclosed confidential information about impending block trades to select investors.

The SEC found Morgan Stanley failed to enforce information barriers intended to prevent material nonpublic information from crossing from the private side of the bank to a public-side trading division. The regulator said the information involved potential block trades that could move stock prices.

Morgan Stanley’s own policies at the time prohibited employees from sharing confidential information with colleagues unless they had a legitimate business reason to receive it, according to the SEC’s order. The firm also maintained watch lists and surveillance procedures designed to prevent the misuse of material nonpublic information.

Morgan Stanley agreed to pay approximately $138 million in disgorgement, $28 million in prejudgment interest and an $83 million civil penalty in the SEC case. The firm paid roughly $249 million in total under the SEC and parallel criminal settlements after credits between the resolutions were applied.

The latest incident differs from the conduct alleged in the 2024 case, which involved intentional disclosures of confidential block-trade information.

Morgan Stanley did not respond to the Daily Caller News Foundation’s additional questions about whether the document contained material nonpublic information, whether regulators or affected clients had been notified and whether the bank implemented additional safeguards following the incident.

The SEC did not respond to the DCNF’s request for comment on whether it was aware of or reviewing the incident and whether an inadvertent disclosure of confidential transaction information could trigger regulatory obligations.
