Interpreting Recent Changes in the Credit Spreads of Japanese Banks

This paper examines the recent period of relatively low credit spreads in Japan, with particular emphasis on the marketfs assessments of the credit risks of large Japanese banks implicit in the prices of credit derivatives. We extract the market-price implied likelihood of a credit event in the future, and explore the nature of the default risk premiums underlying recent changes in bank bond and credit derivatives prices. We document substantial increases in the gjump-at- defaulth default risk premiums for the large Japanese banks examined during the early part of 2006. These patterns in risk premiums are related to the recent patterns in market indicators of global event risk, local equity market volatility, and an estimate of the duration of the Bank of Japanfs zero interest rate policy.
