About USD/JPY
USD/JPY is the exchange rate between the US dollar and the Japanese yen, one of the most traded currency pairs. It shows how many yen one US dollar buys.
Spot forex closes each weekend, but WeekendIndex shows a live USD/JPY rate 24/7, implied from markets that trade continuously. These are implied market prices, not official fixings.
Frequently asked questions
Can I see the USD/JPY rate on weekends?
Yes. The interbank forex market closes from Friday evening until Sunday evening New York time, so the official USD/JPY rate stops updating. WeekendIndex shows a live USD/JPY rate 24/7, so you can check it on Saturday and Sunday.
Where does this USD/JPY rate come from?
It is implied from markets that trade the same currencies around the clock, cross-checked across venues. It is an implied market rate, not an official interbank fixing, and it can differ slightly from where the pair reopens.
Why is USD/JPY moving when the forex market is closed?
Because the markets it is derived from never stop trading. USD/JPY often reacts to weekend news before the interbank market reopens on Sunday evening, which is why it is useful to watch when forex is shut.
