New York: The dollar appreciated in late trading on Friday amid falling sterling, as market participants awaited more updates concerning Brexit.
The dollar index, which measures the greenback against six major peers, was up 0.20 per cent at 97.8311 at 3:00 p.m. (1900 GMT), the Xinhua news agency reported.
Sterling was under pressure as Brexit uncertainty lingered.
British Prime Minister Boris Johnson on Thursday called for a December 12 general election, in an effort to break the political deadlock over Brexit.
The move came days after the Brexit legislation was in limbo after MPs rejected Johnson's plan to get it through the House of Commons in three days.
