The pound is the world’s worst-performing currency this month, trailing behind about 150 peers, as the first signs of how Brexit will look emerged in October.
Sterling posted its biggest monthly decline versus the dollar since the U.K. voted in June to leave the European Union amid speculation that the government is headed for a so-called hard Brexit, where unfettered access to Europe’s single market is sacrificed for immigration controls. The pound dropped after political headlines and comments from lawmakers and central-bank officials underlined its vulnerability as concern about Britain’s exit from the world’s largest trading bloc intensified.
