The Option Market Priced a Sixty-One-Pip Day. Tokyo Traded Forty, and There Is Still No Expiry Ladder.
One vendor put one-week dollar-yen implied volatility at 6.17 per cent this morning.
On our conventions that is about 61 pips of one-day standard deviation and 135 over the week - and the entire Tokyo session traded 40 pips, two-thirds of one sigma. The dollar index ran 102.20 to 102.075 and back to 102.238, finishing just above a ten-day line the publisher gives as 102.161 and does not label. 159.04 now has a third reader naming it, 69 pips away, 1.12 sigma. Fifth straight slot with no expiry ladder for the 14:00 cut, and two searches returned nineteen results with not one from 2026. Plus a correction: the issuer has published 9 October at 5.24 per cent, so Monday night was not a phantom close, and our 0.32-basis-point figure should have been 2.32.
