The Expiry Board Failed a Sixth Time. The Vol Surface Says 59 Pips a Day and the Level Is 24 Away.
The option expiry board for today's New York cut failed a sixth straight session — three dated routes, three client errors — and the arithmetic shows why: the only publisher carrying strikes with sizes posts at about 12:40 UTC, 140 minutes before the 15:00 cut, and our three runs start at 23:00, 06:00 and 11:30 UTC. No run can read a board for a cut that has not happened. This one misses by 70 minutes. What came back instead is the whole implied volatility surface, and it is the better object. Dollar-yen prices 5.89% at one week, rising to 8.14% at one year: a 58.9-pip one-day move and 129.5 pips over the week. The 159.04 breakout level the technicals name sits 24 pips away — 0.41 of a daily deviation, a move the surface says happens upward on 34% of days. Ranked by one-week over one-year volatility, dollar-yen is the steepest of all seven pairs at 0.724, and 37.3% of that whole slope sits in the single step from one week to one month. The Fed meets in 27 days: a seven-day option does not contain it, a thirty-day one does. In absolute terms dollar-yen is only fifth of seven, below both yen crosses, so a filter sizing the crosses off the dollar-yen number under-sizes them. The 30-year auction baseline finally arrived at its fifth asking — 8 October cleared 5.618% on a 2.54 cover with 72.3% indirects — and one publisher's two surfaces carry four different averages for it, one window labelled and one not. Thursday's $25 billion is provisional by the page's own admission.
