The New York Stock Exchange has partially reopened its famous Wall Street trading floor, with around a quarter of brokers returning after a two-month shutdown caused by the coronavirus crisis.

New York governor Andrew Cuomo rang the opening bell after roughly 100 brokers, mostly from small firms dependent on a physical space on NYSE’s floor, were assigned desks behind Plexiglas screens, and navigated by markers to show where each person may work.

Traders were prohibited from using public transport to get to work, required to sign papers indemnifying the exchange if they caught coronavirus, and asked to follow the exchange’s health regulations — all practices that could become commonplace as financial hubs try to pack up home offices and get back to work.
