Finance leaders from the Group of 20 economies will pledge on Saturday to commit themselves to pursue market-determined exchange rates and refrain from 'competitive devaluation' of their currencies, a G20 source said.

A communique to be issued at the conclusion of G20 finance ministers' and central bank governors' meeting here will state: 'We're all committed to moving toward market determined exchange rates that reflect underlying fundamentals and refrain from competitive devaluation,' said the official, who spoke on condition of anonymity. – Reuters
