Morgan Stanley Leaks 100+ Asia Deal List in Employee Email Misfire

Morgan Stanley is investigating how an employee accidentally sent an internal document containing a confidential list of more than 100 investment-banking deals the firm is pitching and monitoring, primarily across Asia but also spanning Europe, the Middle East, and Africa. The leak occurred when a bank staffer sent the list via email this week; the employee later attempted to retract the message, but a blurred copy was also posted on Instagram by an unknown account.

The document detailed the bank's pipeline of potential transactions, including initial public offerings spanning China, South Korea, and India, as well as private equity and pension fund backing arrangements and projects that have been put on hold. According to people familiar with the matter and a copy reviewed by Bloomberg News, the list represents some of the most significant deals underway in Asia's investment-banking market.

In a statement to Bloomberg News, Morgan Stanley said: "We take 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 is assessing the scope and impact of the incident, though it remains unclear whether affected clients have contacted the firm or what remedial steps are underway.

The incident is a significant embarrassment for Morgan Stanley, which has maintained a top ranking in underwriting Hong Kong stock sales and Asia mergers for years. While such breaches are rare, industry observers note that investment-banking teams typically maintain strict controls over deal information. The leak of 100 deals at once is unusual; similar accidental disclosures at other financial institutions in recent years have led to regulatory penalties and reputational damage. In July 2026, Bank of Baroda disclosed that an employee's email account was compromised, resulting in unauthorized data access.
