The Bank of Japan published its May 2026 basic figures on Japanese government bond settlement fails, reporting 5,349 failed transactions, 10,666 fail occurrences, an average fail period of 1.91 business days per transaction, and zero buy-ins. The release also includes reference data on Japanese government bond delivery-versus-payment settlement volumes and Government Bond DVP direct debit transactions. The survey is based on monthly reports from recipients of JGBs in failed transactions and covers 245 institutions as of the end of April 2026 that are direct participants in the JGB book-entry system and users of BOJ-NET JGB DVP services. It includes settlements through institutions' own accounts, customers' accounts, and trust accounts. A fail is defined as non-delivery of JGBs on the scheduled settlement date, while a buy-in is a purchase used to settle a failed transaction under Japan Securities Dealers Association or Japan Securities Clearing Corporation rules.
