Sterling fell 3.75% against the dollar through the month, logging a decline not seen since the end of last summer. The pound also slid 1.26% against the euro last month, notching its weakest performance since December 2022. Exchange rates have been impacted over the past two years by interest rate expectations, with higher rates generally making a currency more attractive for foreign investment.
