Morgan Stanley staff, clients and visitors that have not been vaccinated against coronavirus are to be barred from entering the bank's offices in New York.

“Starting July 12 all employees, contingent workforce, clients and visitors will be required to attest to being fully vaccinated to access Morgan Stanley buildings in New York City and Westchester,” said an internal memo, signed by chief human resources office Mandell Crawley, reported by the Financial Times.

A person familiar with the memo said all Morgan Stanley staff in the US have to give evidence of their vaccination status via an internal tool by July 1.

Those in New York City and Westchester County that haven't been inoculated will have to work from home from July 12 and restrictions like using face coverings and physical distancing will then be lifted. It is unclear if this policy will be rolled out across all of the bank's offices in America.

Morgan Stanley has already put in place some “vaccine-only” workspaces across some business lines including institutional securities and wealth management, which will be expanded across all areas on July 12.

New York, where the investment bank was founded and is headquartered, has lifted nearly all remaining Covid-related restrictions.

Morgan Stanley's decision comes as firms grapple with getting people back to the office, clashing with staff over the future of working life.

Last week boss James Gorman told bankers that if they are happy going to restaurants, then they can return to the office. Mr Gorman said: "If you can go into a restaurant in New York City, you can come into the office and we want you in the office."

He added at the time that more than 90pc of employees in its Broadway headquarters were now vaccinated and that remote working from locations such as Florida would not be accepted.

"Make no mistake about it, we do our work inside Morgan Stanley offices," he added, saying he would be disappointed if everyone was not back by Labor Day on September 6.

Rival Goldman Sachs, meanwhile, told all US staff they must be back full time from last week, following repeated arguments by boss-turned-DJ David Solomon that working from home will not become permanent after the pandemic.

In the UK earlier this month, book publisher Bloomsbury said it will make Covid vaccines compulsory for all of its employees returning to the office, a decision which proved controversial.

Morgan Stanley has been contacted for comment.
