TIBOR
From ACT Wiki
Tokyo Interbank Offered Rate.
There are two types of TIBOR: JPY TIBOR and Euroyen TIBOR.
The underlying market for JPY TIBOR is the Japan unsecured market.
JPY TIBOR is widely used as a base rate for bank loans in Japan including syndicated loans.
Euroyen TIBOR's underlying market is the Japan Offshore Market (in which financial institutions including banks and non-residents execute JPY transactions).
Euroyen TIBOR is mainly used for derivatives and is not used as often for loan transactions.
Not to be confused with JPY LIBOR.
