FAQs
The 15 year TONA swap rate is the annual fixed interest rate that market participants exchange for annually paid, compounded TONA over the next 15 years. It is set in the interdealer swap market and moves continuously with expectations for Bank of Japan policy.
The rate shown on this page is the previous Japanese business day's close; the live rate is available in the BlueGamma app.
Three common reasons:
- Timing: this page shows the previous Japanese business day's mid-market close, while banks quote off the live curve, which moves through the day.
- Spread: the mid-market rate is the raw interbank level. A bank's quote adds a credit and execution charge, and on a loan a lending margin on top.
- Conventions: a quote using a different payment frequency or day count will differ slightly from the annual/annual rate shown here.
If you are comparing a quote against the market, compare it with the live mid rate at the time of the quote.
Lenders fund fixed-rate commercial and real-estate loans by hedging with interest rate swaps of the matching term, so a 15 year fixed quote is priced off the 15 year TONA swap rate plus a lending margin.
Borrowers on floating TONA loans watch the same rate: it is the market level at which their bank will fix the debt, before the bank's spread.
This page shows the last 12 months of daily closes, the 52-week range and dated lookbacks.
The BlueGamma app carries the full daily history for every TONA tenor, alongside 20+ other currencies, with downloads straight to Excel.
BlueGamma takes quotes directly from leading inter-dealer brokers and exchanges, bootstraps them into ready-to-use curves, and validates the output for consistency on a regular basis.
