While the U.S. late last year extended the retirement date of key dollar Libor tenors by 18 months, such a move has proven impractical in Japan due to a lack of support from the panel banks that help determine the rate. Decisions made by Japanese authorities in recent years have also added an extra layer of complexity to certain parts of the transition.
Unlike in the U.S. and U.K., Japanese officials aren’t pushing market participants toward a single Libor alternative. The decision to reform and keep alive the Libor-like Tokyo interbank offered rate, or Tibor, may slow adoption of TONA, according to Fitch. TONA will be used mainly for derivatives while another benchmark, the Tokyo term risk-free rate, or TORF, will be employed for loans and bonds.
