The FTSE 100 led a forward charge of global stocks as the UK’s private companies felt the pinch in a tough November.
The blue chip index rose 88.26 points, or 1.22%, to 7,326.81, to finish Friday on a week high.
The engines were fired up under Britain’s biggest stocks after the pound crashed. Sterling was pushed lower by new November figures showing the private sector contracted at its fastest rate since July 2016, the month after the Brexit referendum.
One pound bought 1.2828 dollars by the end of the day, a 0.6% decrease. Meanwhile, against the euro, the currency fell 0.34% to 1.1631.
The FTSE 100 is full of companies that depend heavily on exports. A fall in the value of the pound pushes down the price that foreign companies have to pay for FTSE 100 goods and services, therefore boosting the index.
But the index’s rise was not unique. The Dow Jones was trading up 0.27% to 27,841.89, while Germany’s Dax rose 0.2%, and the Cac index of Paris’s biggest companies also closed up 0.2%.
