The resurgent pound jumped higher against the euro and dollar as traders welcomed news that the Brexit Party will not contest previously Conservative-held seats in the upcoming General Election.
Currency traders were optimistic on Monday that Nigel Farage’s decision to stand down some Brexit Party candidates could reduce the likelihood of a hung parliament.
The value of the pound increased 0.6% versus the US dollar at 1.286, and up 0.42% against the euro at 1.165.
Sterling’s bounce came after a steady improvement in recent months as investors hope for Brexit certainty, pulling the pound up to a six-month high against the euro.
Connor Campbell, financial analyst at Spreadex, said: “Sterling’s hero came in an unlikely form on Monday: The Brexit Party.
“Nigel Farage announced that his single-issue group would not contest the 317 seats the Tories won back in 2017. Investors have read this move as one that makes it easier for Boris Johnson to secure a majority.”
Political news drove the change in the value of the pound, as it was left largely unaffected by a mixed set of GDP figures.
Improvements in sterling weighed down international-focused blue-chip companies, while UK-oriented firms, such as banks, were lifted by the currency swing.
