is 1 pound the same as 1 dollar
The result of the 2016 UK referendum on EU membership caused a major decline in the pound against other world currencies as the future of international trade relationships and domestic political leadership became unclear. The referendum result weakened sterling against the euro by 5% overnight. The night before the vote, the pound was trading at €1.30; the next day, this had fallen to €1.23. By October 2016, the exchange rate was €1.12 to the pound, a fall of 14% since the referendum. By the end of August 2017 the pound was even lower, at €1.08. Against the US dollar, meanwhile, the pound fell from $1.466 to $1.3694 when the referendum result was first revealed, and down to $1.2232 by October 2016, a fall of 16%.
