Traders Think Even a Narrow Win Will Boost Pound

The pound could be set for a further rally if U.K. Prime Minister Theresa May avoids defeat in a confidence vote Wednesday, though a victory won’t end turmoil for the currency.The result of the no-confidence vote could come into the currency market’s so-called witching hour if it runs late.It’s due at 9 p.m. London time, but a delay could see it pushed between the end of the New York close and the start of trading in Tokyo, when thin liquidity could exaggerate any moves.
