Herkness, Albert Joseph, Jorge Velazquez, Titus Davidson, Charles Laurencin and Security Director Rick Rescorla) in the towers, while 2,687 were successfully evacuated by Rick Rescorla. The surviving employees moved to temporary headquarters in the vicinity. In 2005 Morgan Stanley moved 2,300 of its employees back to lower Manhattan, at that time the largest such move. In 2003, NewYork–Presbyterian Hospital named the Morgan Stanley Children's Hospital in recognition of the firm's sponsorship of the hospital, which largely funded its construction through philanthropy. The initiative began under CEO Philip J. Purcell and was completed under John Mack. Employees at the firm have been involved with the hospital since the 1990s and personally donated to the construction of the current child-friendly building, which opened in November 2003. The company found itself in the midst of a management crisis starting in March 2005 that resulted in a loss of the firm's staff.

On December 19, 2006, Morgan Stanley announced the spin-off of its Discover Card unit. The bank completed the spinoff of Discover Financial on June 30, 2007.

Aisha de Sequeira, a Managing Director in the Mergers and Acquisitions group, was made Head of Investment Banking. In order to cope with the write-downs during the subprime mortgage crisis, Morgan Stanley announced on December 19, 2007, that it would receive a US$5 billion capital infusion from the China Investment Corporation in exchange for securities that would be convertible to 9.9% of its shares in 2010. The bank's Process Driven Trading unit was amongst several on Wall Street caught in a short squeeze, reportedly losing nearly $300
