BNY Mellon is set to introduce 24/7 settlement for U.S. Treasuries by 2027, responding to the digital asset market's impact on traditional finance. The bank plans to launch tokenized U.S. Treasuries by the end of 2026 and conduct pilot trading on its private blockchain. Earlier this year, BNY Mellon facilitated after-hours Treasury trades with stablecoin issuers Ripple and OpenEden, demonstrating the potential for continuous market activity beyond traditional hours.
