TIBOR
The Tokyo Interbank Offered Rate is the Japanese yen term reference rate, administered by the JBA TIBOR Administration. It is published for each business day across tenors from one week to twelve months.
How it is put together
TIBOR is a submission-based rate. Each reference bank submits its rate for every tenor on every business day. The highest and lowest submissions are excluded and the rate is the average of what remains, so no single panel bank can move the fixing on its own.
Because it is a term rate, TIBOR carries both the expected path of overnight rates over the tenor and a bank funding component. That second part is what the spread against compounded overnight TONA is measuring, and it is where most of the interesting movement shows up.
