Mastercard’s commitment includes sharing insights from the private sector’s development of retail payment systems to aid in the successful implementation of CBDCs.

Mastercard outlines foundational principles for designing effective Central Bank Digital Currencies (CBDCs), emphasizing the importance of partnerships between public and private sectors. These principles aim to modernize payment systems, enhance financial inclusion, and ensure interoperability with existing payment methods. Mastercard’s experience in global payment ecosystems informs these guidelines, which advocate for consumer protection, anti-money laundering standards, and maintaining a level playing field for all participants1. The principles serve as a blueprint for central banks considering CBDCs to support economic growth and maintain trust in the financial system.
Central banks exploring CBDCs should adhere to a set of core principles to meet consumer needs, ensure financial system health, and maintain access to diverse payment options:
Right tool for the job: Evaluate CBDCs against other payment systems like RTP to determine the best fit for the market’s current stage and policy goals.
Interoperable and open acceptance: CBDCs should work smoothly with existing payment methods and networks, including digital IDs, to enhance the payment ecosystem and uphold central bank currency.
Two-tier with private sector participation: A two-tier structure involving private sector participation is ideal for fostering innovation and ensuring the central bank governs the monetary infrastructure while the private sector drives CBDC distribution and user experience.
Consumer Protection: CBDCs must offer transaction protections, both offline and online, with clear standards and rules to gain and retain consumer trust.
Mastercard advisory services assist central banks in navigating the initial challenges and envisioning the future of Central Bank Digital Currencies (CBDCs) through a three-step process:
Explore: This initial phase involves evaluating the suitability of a CBDC based on the central bank’s strategic objectives, ecosystem requirements, and use cases. Mastercard guides discussions on user value propositions, design choices, technology considerations, and use case prioritization.
Define: In this phase, Mastercard helps central banks develop a framework for their payment ecosystem, defining CBDC attributes, deployment models, policy features, and requirements. They provide advice on governance, customer management, dispute resolution, and ecosystem performance management.
Use Case Design: Mastercard details potential CBDC payment use cases or user stories, assessing challenges, benefits, and implications for stakeholders. They prioritize these use cases and prepare a test plan for transaction testing in a controlled environment, the CBDC Sandbox.

The CBDC Sandbox is a groundbreaking platform developed by Mastercard to assist central banks in evaluating and exploring the implementation of national digital currencies. This innovative testing environment allows for the simulation of a local payments ecosystem within a controlled setting, enabling central banks to assess the feasibility and potential impact of CBDCs without any initial technology investment.
Modular Approach: The Sandbox’s modular design facilitates rapid feasibility assessments and helps central banks understand the value CBDCs could bring to their markets.
Core Capabilities: It supports testing of key functionalities like CBDC issuance, distribution, and exchange, as well as flexible governance rules and technology designs.
Customization: Central banks can customize the virtual platform to reflect their operational environment, testing various CBDC technology designs and use cases.
Comprehensive Testing: The CBDC Sandbox allows for the examination of CBDC use in transactions, such as consumer payments for goods and services, and the evaluation of technical build and security aspects of CBDC design and operations.
Overall, the CBDC Sandbox is a vital tool for central banks to navigate the complex landscape of digital currencies, ensuring informed decision-making and strategic implementation.
The advantages of the Mastercard CBDC Sandbox, as outlined in the document, are:
Comprehensive Testing: It evaluates all three layers of a CBDC: issuance, distribution, and transactions, enabling central banks to validate value propositions and identify pain points across all financial ecosystem participants.
Expert Design: Thoughtfully created by experts with global experience in running payment networks and addressing industry pain points.
Quick and Cost-Effective: Assesses the feasibility of CBDC issuance and transactions for a specific market quickly and without significant investment or new resources.
Mastercard Execution: Mastercard collaborates with central banks to set up and configure the platform, run tests, and provide monetary policy expertise.
Mastercard Advisors can assist central banks in rolling out a chosen CBDC through an integrated approach that maximizes value realization. They provide end-to-end guidance and support to streamline the process from development to launch, ensuring a smooth transition and minimizing risks. This includes:
Accelerating Implementation: Offering program management and development assistance to realize the digital currency vision. Mastercard offers a comprehensive suite of services including a central program management office, internal client coordination with steering committee oversight, project management across various dependencies and timelines, as well as development and integration assistance.
Driving Adoption: Aligning design sprints with product releases to encourage engagement and coordinating with payment ecosystem players for broad acceptance. Mastercard assists central banks in strategizing the launch of a CBDC by developing partnerships with regional commercial banks, coordinating with payment ecosystem players, ensuring interoperability for widespread merchant acceptance, and more.
Continuous Evolution: Supporting ongoing improvement and development based on feedback to maintain engagement and build new capabilities. Mastercard’s expertise in payment ecosystems ensures an efficient path to value realization and the best user experience. The evolution and ongoing governance of the CBDC solution will offer a proven test and learn methodology for quantitative insights, a steering committee to review and align with the business case and more.

Cybercrime costs are projected to rise to $10.5 trillion USD by 20251. CBDCs must be safeguarded against sophisticated cyberattacks. Mastercard, with its experience in securing global payment systems, can assist central banks in protecting CBDCs. Three major challenges are mentioned in the whitepaper.
Infinite Endpoints: CBDCs introduce numerous endpoints, each a potential vulnerability. Mastercard’s RiskRecon tool helps monitor and act on security risks across the digital supply chain, assessing third-party service providers and vendors to reduce cyber threats.
Viewing risk across the ecosystem: CBDCs require a network-level view to trace financial crime across the ecosystem. Mastercard’s Trace Financial Crime solution provides a global perspective, aiding in the identification of criminal networks and the repatriation of stolen funds.
Having a global view of the threat-landscape: Cybercriminals often disable internal monitoring systems before attacks. Mastercard’s Safety Net uses AI to provide a secondary defense layer, independent of internal systems, and offers global insights into fraud trends to protect the CBDC ecosystem. Mastercard Cyber & Intelligence Solutions deploys these tools to secure payment systems against sophisticated cyberattacks, ensuring the safety and trustworthiness of CBDC transactions3. These solutions offer central banks a robust defense strategy, leveraging Mastercard’s extensive experience in securing global payment networks.

Mastercard aims to create a digital economy beneficial for all, leveraging over 50 years of experience in payment systems to ensure safety and resilience. Emphasizing the importance of public trust, Mastercard invests in innovative payment solutions like blockchain to support central banks in launching digital currencies. The company advocates for public-private partnerships to foster payment innovation, financial inclusion, and efficient payment flows.
