France, Singapore, Switzerland CBDC Experiment Achieves Success: Project Mariana's Breakthrough
The future of cross-border payments is here. A groundbreaking collaborative project involving the central banks of France, Singapore, and Switzerland, in conjunction with the Bank of International Settlements (BIS), has demonstrated the potential of central bank digital currencies (CBDCs) for efficient and seamless international transactions.
This ambitious experimental study, known as Project Mariana, has achieved remarkable success, paving the way for a new era of global financial connectivity. 28 de sept. de 2025 The central banks of France, Switzerland, and Singapore collaborated with the Bank of International Settlements (BIS) to conduct a joint test for cross-border payments. This collaboration highlights the growing recognition of the need for innovative solutions to address the challenges of traditional cross-border payment systems.
Project Mariana: Revolutionizing Cross-Border Payments with CBDCs
So, what made Project Mariana so successful? The experiment delved into the realm of decentralized finance (DeFi) to explore how wholesale CBDCs could be leveraged to streamline foreign exchange transactions. 29 de sept. de 2025 Experiment Details: BIS said its Project Mariana successfully used decentralized finance technology to pool hypothetical wholesale CBDCs to enable foreign exchange and cross-border payments. The project's findings have been lauded as a significant step forward in understanding the potential of CBDCs.
The success of Project Mariana hinges on its innovative use of DeFi principles. By creating a shared platform for pooling hypothetical CBDCs, the experiment demonstrated how foreign exchange transactions can become more efficient, faster, and transparent. This represents a significant leap from the often slow and costly processes associated with traditional cross-border payments.
Key Findings from the Banque de France Report
Further details about the experiment and its outcomes can be found in a report published by the Banque de France. 28 de sept. de 2025 According to a report published by the Banque de France on Septem, the experimental study, named Project Mariana, tested the cross-border trading of CBDCs in a controlled environment. This report provides valuable insights into the technical aspects of the project and its implications for the future of international finance.
The results of Project Mariana are a testament to the power of international collaboration and technological innovation. As central banks around the world continue to explore the potential of CBDCs, Project Mariana serves as a valuable blueprint for future initiatives aimed at improving the efficiency and accessibility of cross-border payments. The experiment marks a pivotal moment in the evolution of global financial infrastructure, demonstrating that CBDCs have the potential to transform the way the world moves money.
