British Pound futures declined following a straight down session, closing near daily lows. The downturn came despite positive UK economic indicators, as the final manufacturing PMI for May reached a four-year high of 53.9 and services PMI came in at 49.3, both beating flash estimates. However, the drop in services below the 50 threshold signaled softening momentum ahead of the June 18 Bank of England rate decision. Additionally, sentiment was weighed down by a new U.S. proposal introducing additional tariffs of 10% to 12.5% under Section 301, with the UK specifically positioned in the 10% tier.
