New York state’s top financial regulator has demanded documents from more than a dozen banks including Barclays, Deutsche, Goldman Sachs and RBS as a probe widened into trading practices in the $5.3tn-a-day global foreign exchange markets.
Benjamin Lawsky, New York's financial services superintendent, made the move following the banks’ decision to fire or suspend at least 20 traders following reports that employees at some firms had shared information about their currency positions with counterparts at other companies.
A source in Lawsky’s office said the investigation, which also brought in Credit Suisse and Standard Chartered, was at an early stage. “We are investigating a broad range of concerns about foreign exchange trading at these institutions,” said the source, who asked not to be identified.
Lawsky’s move marks the latest escalation in a global investigation by regulators into the manipulation of benchmark rates. The currency probe comes as regulators are still investigating the manipulation of the Libor lending rate by traders at some of the world’s biggest banks.
