MBridge

mBridge (a.k.a. Multiple CBDC Bridge) is a multi-CBDC platform developed to support real-time, peer-to-peer, cross-border payments and foreign exchange transactions using CBDCs. Based on a blockchain called the mBridge Ledger, the platform is designed to ensure compliance with jurisdiction-specific policy and legal requirements, regulations, and governance needs.[1]

Currently five entities are jointly developing mBridge. They include the Hong Kong Monetary Authority (HKMA), the Bank of Thailand (BoT), the Central Bank of the United Arab Emirates (CBUAE), the Digital Currency Research Institute of the People's Bank of China (PBC DCI), and the BIS Innovation Hub Hong Kong Centre (BISIH Hong Kong Centre).[1]

Development

A pilot involving real corporate transactions was conducted on the platform among participating central banks, selected commercial banks, and their customers in four jurisdictions. The project focused on developing hypothetical use cases in the Greater Bay Area (GBA) as a way to demonstrate the technology and operational improvements that mBridge can offer.[2]

In September 2021, the Bank for International Settlements (BIS), in collaboration with Thailand, Hong Kong, China, and the UAE, published a report regarding the second phase of the mBridge project, aiming to establish a system involving multiple CBDCs to enable faster, more cost-effective, and efficient methods for conducting cross-border transfers and foreign exchange operations.[3]

The HKMA expressed the intent to collaboratively launch a minimum viable product in 2024, with the effort built on the G20's focus on exploring new technologies to provide more cost-effective and secure real-time cross-border payments and settlements.[4]

Alongside mBridge, there are also other ongoing projects aiming to improve cross-border transactions with CBDCs.[4]

Dunbar

On 22 March 2022, the BIS Innovation Hub, the Reserve Bank of Australia, Bank Negara Malaysia, the Monetary Authority of Singapore, and the South African Reserve Bank announced the completion of prototypes for a shared Dunbar platform, enabling international settlements using multiple CBDCs.[5]

Cedar x Ubin+

The Cedar x Ubin+ project, the flagship venture of the New York Innovation Center (NYIC) in collaboration with the Monetary Authority of Singapore, is a multi-phase technical research initiative that evaluates the potential applications of wholesale CBDCs, built with distributed ledger technology to enhance the efficiency and transparency of cross-border payments.[6][7]

Mariana

In October 2023, the Bank for International Settlements, in partnership with the central banks of France, Singapore, and Switzerland, confirmed the successful completion of the Mariana project, which explored cross-border trading and settlement of wholesale CBDCs among financial institutions while integrating decentralized finance technology on a public blockchain.[8]

Icebreaker

In March 2023, the Bank for International Settlements, in collaboration with the central banks of Israel, Norway, and Sweden, completed the Icebreaker project, which examined the technical feasibility of using retail CBDCs in international payments.[9]

Jura

In November 2021, the consortium responsible for Jura project, comprising the Bank for International Settlements, Banque de France, Swiss National Bank, and various private firms, explored the direct transfer of Euro and Swiss franc wholesale CBDCs between French and Swiss commercial banks on a single distributed ledger platform. The group officially confirmed the experiment's success in a report released on December 8, 2021.[10][11]
