Japanese 10-Year Government Bond

This asset is futures listed on the venue linked above — a typed relationship in the dataset, not a name that happened to match. The parties named after it (OTC interdealer market) matter to how it trades but are not entities here.

No live level is shown for this asset: our open, keyless sources cover crypto, major FX crosses, the ECB policy rate, the US 10-year yield and US CPI — index levels and commodity prices are only available from licensed vendors, and we do not publish figures we cannot source openly.
