The British pound declined against the euro as the European Union and Britain said substantial differences remained over a Brexit trade deal as the EU chief negotiator prepared to travel to London in a last-ditch attempt to avoid a tumultuous finale to the five-year Brexit crisis.
Along with the data and Brexit headlines, Erik Bregar, head of FX strategy at Exchange Bank of Canada in Toronto, cited month-end selling of the U.S. dollar as investors balance portfolios after solid monthly gains for equities.
"There's been talk all week that the U.S. dollar will see waves of selling going into Monday," said Bregar who also noted "dollar selling into the London fix every day this week."
But with many U.S. traders still on vacation a day after Thursday's Thanksgiving holiday, Bipan Rai, North America head of FX Strategy at CIBC Capital Markets, said thinner trading volume was likely exaggerating the dollar move.
"It started with the impressive industrial profits data in China and that's translating into what is a very patchy backdrop for liquidity in the North American time zone," said Rai.
However, "over the longer term this is probably the right trend for the dollar. We think the dollar has further room to the downside," he added.
Wall Street indexes advanced, with the Nasdaq closing at a record high, in Friday's truncated session as retailers kicked off the year-end shopping season and COVID-19 hospitalizations hit records.

Citing Brexit, Scottish leader Nicola Sturgeon said an independence vote should take place in the earlier part of the devolved parliament's next term, which begins next year.
The euro was up 0.39% at $1.1952, barely reacting to downbeat comments from the European Central Bank's chief economist Philip Lane on Thursday.
