A technical glitch halted most FX futures trading on the Chicago Mercantile Exchange's electronic dealing platform Globex on Friday, according to a report by Reuters.
Reuters says trading in the Japanese yen, Canadian dollar, Mexican peso, British pound, Swiss franc and EuroFX futures was suspended at 8:15am CDT because some traders were unable to enter or cancel currency orders on the Globex system.
Trading on CME's open-outcry trading floor was not affected.
A CME spokesperson told Reuters that the exchange's technical teams resolved the problem and trading resumed at 9:45am CDT.
The systems failure is the second to hit Globex this year - in April exchange was forced to halt Eurodollar futures trading on the platform for three hours after some users experienced trouble accessing the system.
On Wednesday this week a systems glitch forced both the New York Stock Exchange and the American Stock Exchange to close trading four minutes early.
Nyse chief executive John Thain told reporters that the problem occurred by a "network storm" - the exchange's computer system and backup were overwhelmed by an error message that duplicated millions of times.
He says Nyse has taken measures to ensure the problem does not happen again.
