Trading in the three big currencies on the platform - the dollar, euro and Japanese yen - rose by as much as 52 percent from October, ICAP said, as expectations of higher inflation under Trump drove a sustained dollar rally.

"Increased confidence about a December rate hike by the U.S. Fed also spurred buying of the greenback," ICAP said.

London-based ICAP said last month its platforms saw the second-biggest volume of business in U.S. Treasuries on record and a doubling of currency volumes on the night of the U.S. presidential election.
