Overlooked details about the Tokyo 9:55 fix and USD/JPY
Posted: Sat Oct 31, 2026 11:27 am
The 9:55 Tokyo fix gets mentioned constantly and understood rarely. A few things that tend to get skipped:
- The fix is a rate set by Japanese banks around 9:55 local time, and it is used by importers and others who need a reference price for dollar settlements. Importers often need to buy dollars, which is why the pressure is usually described as dollar-buying into the fix.
- The effect is widely said to be stronger on gotobi days, meaning days of the month that are multiples of five, because payment dates cluster there. That is a market observation, not a law, and it varies from year to year.
- Weekends and holidays move the payment date, so the 5th falling on a Saturday can shift the pressure to the Friday before or the Monday after.
- The buying often shows up before 9:55 as a gradual grind higher, and the unwinding can follow once the window is over. Entering at 9:50 because of the story means joining late.
- Large flows can be offset by exporters or by macro news that morning. A weak yen story does not override a strong risk-off headline.
- Spreads on USD/JPY at that hour are usually fine, but cross pairs like EUR/JPY can look different depending on the broker.
None of this makes the fix a signal on its own. It is a bias that shows up some days and not others.
If USD/JPY on gotobi days is part of anyone's routine, has the pattern held up across the last couple of years, or has it faded?
