Singaporean Regulator Proposes Framework for Digital Money Use
The Monetary Authority of Singapore (MAS) has released a White Paper that outlines proposed standards for the use of digital assets. The aim is to establish a common protocol and conditions for the utilization of these assets.
While the paper identifies the potential digital assets bring in streamlining transactions and promoting financial inclusion, it also outlines challenges that need to be addressed before digital money can be successfully implemented.

Purpose Bound Money (PBM)
MAS’s White Paper, which was published on Wednesday, provides requirements to protect the use of digital assets as a medium of exchange and offers a technical overview of Purpose Bound Money (PBM). PBM allows the sender of digital money to specify certain conditions such as validity periods or how the money can be spent.
The covered digital monies include central bank digital currencies (CBDCs), tokenized bank deposits, and potentially well-regulated stablecoins, excluding digital assets that it considers volatile such as Bitcoin. These digital monies are generally pegged to real-world currencies, commodities, or financial institutions, making them more stable.
MAS highlights that PBMs utilize a common protocol compatible with different ledger technologies and forms of money. This protocol enables money to be directed toward a specific purpose without requiring the money itself to be programmed. It functions as a secure two-layered delivery vehicle, with funds held as collateral in a “wrapper” until specific conditions are met for its release.
Standardized format
The standardized format outlined in the White Paper will allow users to access digital money using their preferred wallet provider. By establishing these standards, the prospects for digital money to become a significant component of the future financial and payments landscape are enhanced. Standardization and regulated use of PBMs can unlock economic value, facilitate efficient and inclusive digital transactions, and provide additional consumer protection.
One notable application of PBMs is in protecting online payments, such as e-commerce transactions and prepaid packages. With PBMs, advance payments can be securely held until the service is fulfilled, ensuring that the product or service is delivered before funds are released. This benefits both consumers and merchants, assuring consumers of product delivery and allowing merchants to verify payment before delivering.
PBMs can also aid businesses in mitigating risks associated with international trade transactions, ensuring secure and efficient payments while reducing the potential for fraud or non-payment.
Interoperability
To ensure the safety and usability of digital monies, MAS highlights considerations that will impact PBM implementation. Interoperability across different platforms is crucial to avoid fragmentation and excessive fees. The choice of underlying digital currencies also affects usability and value, with CBDCs, tokenized bank liabilities, and stablecoins offering varying levels of guarantees and regulatory oversight. Additionally, privacy, digital readiness, and the impact on users need to be carefully assessed.
MAS acknowledges that the regulatory landscape for digital monies is still evolving globally, which may lead to varying regulatory treatment of PBMs across jurisdictions. It believes that policy considerations should be thought through when designing PBM-based solutions, including decisions regarding issuance, distribution, and conditions for use.
