What would change Antevo's mind about the current view?
This is the case the library exists to publish. The policy call was right and the price call was wrong, and the gap between them is information: the currency is being set by where capital is going rather than by what it earns. We record the failure at the same size as we would have recorded the success.
**Marked to market, 20 September — the named test resolved, and the view it tested did not survive intact.** The single falsifier carried here for the currency view was the Bank of Japan decision of 18 September, carried at 1.25% against a standing 1.00%. It was delivered. The yen then weakened rather than firmed, settling 156.85 per dollar and 2.21% lower across the week, and it did so with the largest speculative net long in three months already in place — 120.4 thousand contracts in the report dated 18 September, from 10.8 thousand a week earlier and minus 163.4 thousand on 31 July. A view that is proved right on the policy and still loses on the price has been falsified on its mechanism even though its forecast was correct, and that is the honest way to record it: the rate differential is not currently setting this exchange rate.
Read the rest
Every position carries a falsifier stated before the fact, and it is scored when events touch it rather than only when it resolves.
The two conditions this position last named have both resolved. The first required a five-year yield breaking below 4.23% with crude still near $88; the five-year rose to 4.55% and Brent settled $97.21, so it went the other way on both legs. The second required euro-area headline inflation at or below 2.9%; it printed 3.3% on 1 September, against 2.9% the month before. Neither fired, and the view they tested was kept.
One did fire, in a different position and against us. Crude net length was named as a falsifier if defended rather than reduced; it was rebuilt to 94,281 contracts in the week to 1 September from 84,020, above the level that set the test. That reading is published as weakened.
The current view carries its own condition, and it is a single dated event. The brief holds that the dollar's fall to 153.90 against the yen on 7 September was a repricing of the Japanese policy path rather than a crowded position unwinding — evidenced by a dollar index that finished unchanged on the same session and a euro that moved forty times less over the window. It names one way to be wrong: the Bank of Japan holding at 1.00% on 18 September with the pair retracing through 158. That is measurable inside a fortnight, and it will be scored.
