  • Citigroup told employees late Wednesday in a memo that they will now be required to wear masks in U.S. corporate offices, according to a person with knowledge of the situation.
  • The bank is following CDC guidance that changed this week, according to the person who declined to be identified speaking about the company's plans. Other Wall Street firms including Morgan Stanley are closely monitoring the situation, said another person with knowledge.
  • JPMorgan Chase had no changes from its latest guidance, which allowed the vaccinated to relinquish masks and daily health attestations as of this month, according to a person familiar with its planning.
Traders wearing masks work inside posts, on the first day of in-person trading since the closure during the outbreak of the coronavirus disease (COVID-19) on the floor at the New York Stock Exchange (NYSE) in New York, U.S., May 26, 2020.

For a few glorious weeks, Wall Street employees who were vaccinated against Covid-19 could ditch their masks at the office.

That appears to be ending after the Centers for Disease Control and Prevention recommended this week that even fully vaccinated people should wear masks indoors in areas with significant transmission rates.
