Morgan Stanley’s accidental leak of confidential information about its Asian deal pipeline has raised questions about the potential impact on customer relationships.
The disclosures may have affected competition, the people said, but they do not necessarily mean Morgan Stanley will lose power as a result, raising questions about how much lasting damage it could cause to the bank’s deal business.
For example, one buy-side official currently working on deals with Morgan Stanley said Morgan Stanley has no plans to reconsider its mandate with the bank.
The person said many of the transactions disclosed were already widely known in the industry and did not expect the leaks to have a material impact.
Another person whose company is currently working with Morgan Stanley to raise capital said the company has no plans to reconsider its authority over the case and said the issue has received little attention.
Still, bankers familiar with the matter said the impact could vary depending on the customer and how they view the incident, giving a more cautious assessment of the potential impact.
Some trades were still in progress, and other banks could have used that information to see if they missed out on potential deals, the banker said.
The banker added that while customers will be dissatisfied with the incident, it is unlikely to fundamentally erode customer trust in Morgan Stanley.
Last week, it was reported that Morgan Stanley’s top bankers mistakenly sent some clients an internal list containing more than 100 deals the bank was working on or monitoring, primarily in Asia but also in Europe, the Middle East and Africa.
Morgan Stanley did not respond to CNBC’s request for comment.
