DBS (D05), Singapore's largest bank by market cap, said it has become the first Asian bank to use JPMorgan's (JPM) blockchain-based fixed income trading network Onyx, joining international heavyweights including Goldman Sachs (GS) and BNP Paribas (EPA).

The Onyx Digital Assets network uses tokens for short-term trading in fixed income markets, enabling investors to lend assets for a period of hours without them leaving their balance sheets.

Trades on the repurchase – also known as "repo" – market are for the most part backed by government bonds, making it a vital source of source of collateral for banks to fund their balance sheets.

The aim of the Onyx network is to allow banks to settle such transactions in a matter of hours, as opposed to the one or two working day-period it has taken historically.

Over $300 billion of intraday repo deals have been carried out on Onyx since JPMorgan launched it in 2020.
