The Russian ruble plunged past the mark of 70 to the British pound on Thursday morning amid an ongoing currency rout driven by weak oil prices and Western sanctions on Moscow over Ukraine.
A pound was worth 70.14 rubles on Monday morning as the ruble fell sharply following the U.S. Federal Reserve's announcement that it was ending its quantitative-easing program and ahead of a meeting of the Russian Central Bank on Friday.
The ruble was the world's worst performing currency over the last three months, according to data from Bloomberg.
The ruble has lost 37 percent of its value against the pound since Oct. 30 last year and 22.3 percent since the beginning of 2014. Just seven weeks ago, a pound was worth less than 60 rubles.
