Abstract

Pricing in the euroyen market is based on LIBOR, the London Interbank Offered Rate, set at 11:00AM London time or TIBOR, the Tokyo Interbank Offered Rate, set at 11:00AM Tokyo time. The changing TIBOR-LIBOR spread reflects the credit risk associated with Japanese banks or the “Japan premium”. The spread is modeled as a function of determinants of bank default and firm value. Systematic variation in the spread can be explained by interest rate and stock price effects along with public information flows of good and bad news regarding Japanese banking, with a separate role for bank credit downgrades and upgrades.
