BNY, the world’s largest custody bank, plans to support round-the-clock settlement of conventional and tokenized U.S. Treasuries in 2027, after completing an after-hours trade involving the reserves of 2 stablecoin issuers. The bank will test tokenized Treasuries on a private blockchain by the end of the year and will extend its existing settlement network later this year to cover more of the Asian, European and U.S. trading days, according to a letter sent to clients reported by Bloomberg.
