JPMorgan has asked its US employees to reveal their Covid-19 vaccine status and highlighted it could make vaccines mandatory, as large investment banks on Wall Street prepare to ramp up return-to-office plans.

The investment bank told its US-based employees that they must reveal their vaccine status by 30 June, according to a memo sent to employees yesterday. Staff have the option of not revealing their vaccine status, but still need to respond to the request, the bank said.
