Citi has become the first digital custodian participant of BondbloX Bond Exchange (BBX), the world’s first fractional bond exchange using distributed ledger technology. BBX was launched in 2020 to simplify bond investing by allowing investors to track and trade bonds electronically. The partnership enables Citi’s clients that meet certain criteria to become BBX participants and begin trading bonds (both fractionalized and full-sized) almost immediately, with Citi providing settlement and custody services. Citi was initially chosen by BondbloX in 2021 to act as custodian for the underlying bonds issued and traded on its exchange as fractionalized assets.
