BANK FOR INTERNATIONAL SETTLEMENTS WILL TEST DEFI IMPLEMENTATION IN FOREX CBDC MARKETS

Last updated: June 19, 2025, 22:19 | Written by: Changpeng Zhao

The financial world is on the cusp of a significant transformation, driven by the convergence of traditional finance and decentralized finance (DeFi).In a groundbreaking initiative, the Bank for International Settlements (BIS), in collaboration with the central banks of France, Singapore, and Switzerland, is embarking on a project dubbed ""Mariana"" to explore the potential of DeFi in automating foreign exchange (forex) markets and settlement using central bank digital currencies (CBDCs).This pilot program signifies a pivotal moment, potentially rewriting the rules of cross-border transactions and paving the way for a more efficient, transparent, and secure global financial system.Project Mariana will leverage automated market makers (AMMs) to facilitate the exchange of hypothetical wholesale CBDCs, specifically the Swiss franc (CHF), Euro (EUR), and Singapore dollar (S$).But what does this mean for the future of finance, and how will it impact the roles of central banks and commercial institutions alike? It tested the cross-border trading and settlement of hypothetical euro, Singapore dollar and Swiss franc wholesale central bank digital currencies (wCBDCs) between simulated financialLet's dive deep into the intricacies of Project Mariana and its potential implications.

Understanding Project Mariana: A Deep Dive

Project Mariana is not just another experiment in the digital finance space; it's a carefully orchestrated endeavor designed to investigate the practical application of DeFi protocols in a highly regulated environment. assets in wholesale CBDC. ④③ Cross-border settlement using wholesale CBDC. International settlements using multi-CBDCs. ⑤ Connecting economies through CBDC. ⑦ ⑥ CBDCs in automated market-makers. A two-tier retail CBDC system. ⑧ A cyber-secure retail CBDC architecture. ⑨ Application programming interface to distribute retail CBDC.The core objective is to explore the feasibility of using automated market makers (AMMs) for cross-border exchange of wholesale CBDCs.This innovative approach promises to enhance the efficiency and speed of forex transactions, while also reducing costs and risks.

What are Automated Market Makers (AMMs)?

AMMs are a cornerstone of the DeFi ecosystem.Unlike traditional exchanges that rely on order books and market makers, AMMs use algorithms to automatically determine the price of assets based on their supply and demand within a liquidity pool.This eliminates the need for intermediaries, making trading more accessible and efficient.In the context of Project Mariana, AMMs will be used to facilitate the exchange of hypothetical CHF, EUR, and S$ wholesale CBDCs.

The Role of Wholesale CBDCs

Wholesale CBDCs are digital currencies issued by central banks and designed for use by commercial banks and other financial institutions.They differ from retail CBDCs, which are intended for use by the general public. According to a new announcement on Nov. 2, the Bank for International Settlements, or BIS along with the central banks of France, Singapore and SwitzerlandBy focusing on wholesale CBDCs, Project Mariana aims to improve the efficiency of interbank transactions and cross-border payments.

Why is the BIS Exploring DeFi for Forex CBDCs?

The BIS, often referred to as the ""central bank for central banks,"" plays a crucial role in fostering international monetary and financial cooperation. The Bank for International Settlements (BIS) says that decentralized finance (DeFi) could help write the blueprints for the security of future central bank digital currencies (CBDCs).Its involvement in Project Mariana underscores the growing recognition of DeFi's potential to revolutionize the financial landscape. According to a new announcement on Nov. 2, the Bank for International Settlements, or BIS along with the central banks of France, Singapore and Switzerland will embark on a new initiative dubbed Project Mariana in its exploration of blockchain technology.Here are some key reasons why the BIS is exploring DeFi implementation in forex CBDC markets:

Enhanced Efficiency: DeFi protocols can automate many of the manual processes involved in traditional forex transactions, leading to faster settlement times and reduced operational costs.
Increased Transparency: Blockchain technology provides a transparent and immutable record of all transactions, which can help to reduce fraud and improve regulatory oversight.
Improved Accessibility: DeFi can lower barriers to entry for smaller financial institutions, allowing them to participate more easily in the global forex market.
Innovation and Competition: By exploring new technologies and business models, the BIS hopes to foster innovation and competition in the financial industry.

The Potential Benefits of DeFi in Forex CBDC Markets

The integration of DeFi into forex markets using CBDCs holds immense potential for transforming the global financial system.

Faster and Cheaper Cross-Border Payments: Traditional cross-border payments can be slow, expensive, and opaque. Decentralized finance, or DeFi, protocols will be used by Project Mariana to automate foreign exchange markets and settlement. Project Mariana explores using automated market makers for the cross-border exchange of hypothetical CHF, EUR and S$ wholesale CBDCs.DeFi protocols can significantly reduce the time and cost associated with these transactions.
Reduced Counterparty Risk: DeFi's use of smart contracts can automate the execution of agreements, reducing the risk of default or non-performance.
Increased Liquidity: AMMs can provide liquidity for a wider range of currency pairs, making it easier for businesses and individuals to transact internationally.
Greater Financial Inclusion: DeFi can provide access to financial services for underserved populations, particularly in developing countries.

Challenges and Considerations

While the potential benefits of DeFi in forex CBDC markets are significant, there are also several challenges and considerations that need to be addressed. In keeping with a brand new announcement on Nov. 2, the Financial institution for Worldwide Settlements, or BIS together with the central banks of FranceThe Committee on Payments and Market Infrastructures (CPMI) and the Markets Committee have highlighted the importance of carefully weighing the implications for financial stability and monetary policy.These challenges include:

Financial Stability: The use of DeFi in critical financial infrastructure could potentially amplify systemic risks.Central banks need to carefully assess the impact of DeFi on financial stability and develop appropriate regulatory frameworks.
Monetary Policy: The introduction of CBDCs and the adoption of DeFi could affect the effectiveness of monetary policy. According to a new announcement on Nov. 2, the Bank for International Settlements, or BIS along with the central banks of France, Singapore and Switzerland will embark on a new initiative dubbed Project Mariana in its exploration of blockchain technology. Project Mariana intends to use decentCentral banks need to understand how these changes might impact their ability to control inflation and manage the money supply.
Regulatory Uncertainty: The regulatory landscape for DeFi is still evolving, and there is a lack of clarity on how existing laws and regulations apply to these new technologies. Project Mariana intends to use decentralized finance, or DeFi, protocols to automate foreign exchange markets and settlement. Project Mariana explores using automated market makers for the cross-border exchange of hypothetical CHF, EUR and S$ wholesale CBDCs.This uncertainty could hinder the adoption of DeFi in the forex market.
Cybersecurity Risks: DeFi platforms are vulnerable to cyberattacks, and a successful attack could have significant consequences for the financial system.Robust security measures are essential to protect DeFi infrastructure.
Scalability: Some DeFi platforms struggle to handle high transaction volumes, which could limit their ability to support the demands of the global forex market.
