The HKMA and the BOT published a research report on project Inthanon-LionRock, which aimed to study the application of a central bank digital currency to cross-border payments.
A blockchain corridor network was developed to allow the 10 participating Hong Kong and Thai banks to conduct fund transfers and foreign exchange transactions on a peer-to-peer basis, which helps reduces transactions layers.
The authorities said that the project was successful and confirmed the technical feasibility of implementing practical solutions to address key pain points of cross-border payments, including inefficiencies, high cost, limited traceability and complex regulatory compliance.
Leveraging on smart contracts, the cross-border funds transfer process is enhanced to a real-time and atomic payment-versus-payment (PvP) manner.
The report said:
"The cross-border funds transfer process is enhanced to enable real-time transfers and atomic [payment-versus-payment] settlements. Leveraging smart contracts, funds transfers, and foreign exchange transactions are bundled together. The corridor network is designed to enhance banks’ foreign currency liquidity management, adopted the liquidity saving mechanism for multiple currencies and incorporated compliance to local regulations where possible."
The project, which was completed in December 2019, follows on the memorandum of understanding the HKMA and the BOT signed in May 2019.
