NatWest Markets, a British financial firm, pleaded guilty on Monday to fraud charges tied to the bank’s manipulation of U.S. Treasury markets in a case Justice Department officials touted as part of its clampdown on repeat corporate wrongdoers.

NatWest Markets, which was represented by a team at Wilmer Cutler Pickering Hale and Dorr, pleaded guilty to one count each of wire fraud and securities fraud in federal court in Connecticut, and agreed to pay $35 million in fines and restitution and submit to three years of probation.
