European stock markets climbedFriday, led by London as the pound hit near four-week lows against the dollar.
Earlier, Asian equities closed lower following declines Thursday on Wall Street where the impeachment inquiry into US President Donald Trump weighed on sentiment.
But on Friday, Wall Street was on the front foot again, with Forex.com analyst Faward Razaqzada saying the US market were ready for a breakout after absorbing so much negative news recently.
"What can't break you makes you stronger," he said. "I wouldn't bet against a sharp rally for the US indices today."
A move towards easier central bank monetary policy was helping sentiment, he said.
Bank of England board member Michael Saunders also appeared to open the door to a rate cut, said Fiona Cincotta, senior market analyst at City Index trading group.
But very same factor boosting stock sentiment caused the pound to "tank", she said.
"The comments from Saunders highlight the marked weakening of the UK economy over recent quarters; dragged down not only by Brexit uncertainty but also softer global growth," Cincotta added.
The pound fell to $1.2271, the lowest point in nearly four weeks, before clawing back some of its losses.
The weaker sterling pushed up share prices of multinationals listed on London's benchmark FTSE 100 index.
In commodities, crude prices slipped following the swift recovery in Saudi production that slumped in the wake of attacks on its oil infrastructure two weeks ago.
"The market has been trading lower as oil bulls have been discouraged by the quicker-than-expected return of Saudi oil output," said Stephen Innes, Asia Pacific market strategist at AxiTrader.
Meanwhile, the British-flagged oil tanker Stena Impero, which had been held by Iran for more than two months, set sail and reached international waters Friday, its Swedish owner said.
