An Argentine court on Monday ordered Citibank Argentina not to take any further steps toward quitting its role as custodian of some Argentine sovereign bonds while a row with U.S. creditors over unpaid debt rages on, the government said. President Cristina Fernandez’s government announced last month it was suing the local subsidiary of Citigroup Inc (C.N) for striking an illegal deal with a group of New York-based hedge funds fighting for full payment on defaulted debt.
