Friday was the 9th worst day for the pound since 1862 - here are the other 8
Sterling's 7.64% drop on Friday against the dollar was the largest drop since the collapse of the Bretton Woods currency system in the early 1970s.
It may be rallying a little on Tuesday, higher against the dollar on the day to trade at $1.3296, a gain of around 0.5% from the close on Monday, but, according to Deutsche Bank's Jim Reid, this week has been one for the history books.
Only 8 other days have been more negative for Sterling since 1862 - more than 38,000 trading days.
Deutsche Bank put together a list of the most infamous drops. Here they are in reverse order:
8) 19 June 1866: (-7.76%).
7) 25 Sep 1931: (-7.89%) A few days after the Gold Standard was abandoned, the pound continued to depreciate although it did jump by 7.14% next day.
6) 10 May 1940: (-9.79%) War related deviation from the dollar peg.
5) 25 Mar 1863: (-10.90%).
