The Chicago Mercantile Exchange resumed trading on its Globex platform on Friday after a roughly 10-hour outage halted futures and options markets across Asia and Europe, according to a report by Bloomberg.
The disruption, caused by a cooling-system malfunction at CME’s main Illinois data centre operated by CyrusOne, prevented trading in Treasury futures and SOFR-linked contracts during a week shortened by Thanksgiving in the US.
Activity remained light after reopening, with traders reporting thin liquidity and wider spreads. The incident, triple the length of CME’s 2019 disruption, has prompted questions over the exchange’s contingency protocols, while underscoring the concentration of global futures trading.
