LONDON—Global securities regulators began reviewing on Thursday whether to toughen up operational resilience at exchanges and other market infrastructure in light of the extreme trading volatility in 2020 when economies went into lockdown amid the pandemic.
While much trading is already electronic, the curbs led to the New York Stock Exchange and London Metal Exchange temporarily closing their floors at a time when trading in markets was at its most volatile since Black Monday in 1987 in the United States.
