Stablecoins is a category of cryptocurrencies attempting to control price volatility and achieve price stability by linking the value of the Coins offered by the cryptocurrency to an external asset.
CB Insights defines four types of Stablecoins as depicted in Figure 11).
CB Insights defines the four classes of Stablecoins as follows3):
The U.S. CBDC could be implemented using a Stablecoin.
As with many financial services available over the internet, the technological infrastructure underlying Stablecoins are not restricted to a geographic region. When a Stablecoins becomes popular to man End Users in multiple jurisdictions, it may become a Global StableCoin (GSC). A major confronting GSC are the numerous National laws and regulations in the various jurisdictions. For more details, see the following sections:
GSCs are not without their vulnerabilities. These have been elaborated by The Financial Stability Board4) in Table 1.
Type of Vulnerability | Main Determinants | Functions and Activities Primarily Concerned |
---|---|---|
Financial exposures in the Global StableCoin (GSC) arrangement, giving rise to market, liquidity and credit risks. |
|
|
Weaknesses in the GSC infrastructure, giving rise to operational risk (including cyber risks) and risk of loss of data. |
|
|
Weaknesses in those parts of the GSC arrangement on which users rely to store, exchange and trade GSCs, including operational or fraud risk |
|
|
The type of regulatory coverage of Stablecoin activities varies by jurisdiction.
Regulatory authorities and potential tools to address the vulnerabilities | ||||
---|---|---|---|---|
Activities | Vulnerabilities | Authority/Tool | Relevant international standard | |
Establishing rules governing the Stablecoin arrangement | Fraud or conflict of interest of those governing the GSC arrangement Lack of contractual arrangements among the entities of the Global StableCoin (GSC) arrangement Difficulties to tackle the uncertainty for users due to an unclear definition of roles and responsibilities within the GSC arrangement Inadequate governance framework Lack of clear central body to hold accountable | Ability to regulate and supervise the GSC arrangement in a holistic manner, e.g. through cooperation among authorities (akin to comprehensive consolidated supervision) Ability to require a GSC arrangement to be governed in a manner that facilitates effective regulation and supervision, including by prohibiting fully decentralized systems Governance, internal control, and risk management requirements applicable at the level of the entire GSC arrangement Power to wind down or resolve a GSC arrangement Governance requirements requiring a solid legal basis Cyber security and other operational resiliency safeguards AML/CFT and sanctions controls | The revised FATF Standards apply. Based on known models, developers and government bodies of centralized GSCs will, in general, have AML/CFT obligations as a financial institution (e.g., as a business involved in the ‘issuing and managing means of payment’) or a VASP (e.g. as a business involved in the ‘participation in and provision of financial services related to an issuer’s offer and/or sale of a virtual asset’). They can then be held accountable for the implementation of AML/CFT controls across the arrangement and for taking steps to mitigate ML/TF risks (e.g. in the design of the so-called Stablecoin). This could include, for example, limiting the scope of customers’ ability to transact anonymously using the so-called Stablecoin and/or ensuring that AML/CFT obligations of AML/CFT-obliged intermediaries within the arrangement are fulfilled. For GSC arrangements set up entirely by banks, the Basel Framework and associated principles for supervision and colleges would provide a basis for overseeing the setup. 9) For GSC arrangements deemed to perform systemically important payment system functions or other FMI functions that are systemically important, the PFMI applies. On the basis of a preliminary analysis, some of the most relevant principles regarding these vulnerabilities would be those on a legal basis, governance, and comprehensive management of risks. Responsibility E would provide a strong basis for cooperation among relevant authorities. See Annex 4 on CPMI-IOSCO preliminary analysis. For GSC arrangements where the token or the reserve qualifies as a security, relevant IOSCO Principles and Standards that cover governance arrangements would apply, depending on the structure. These would include relevant cooperation agreements (IOSCO Principles10) covering Cooperation in regulation (Principles 13 to 15), IOSCO’s Multilateral MoU Concerning Consultation and Cooperation and the Exchange of Information,11)the Enhanced Multilateral MoU Concerning Consultation and Cooperation and the Exchange of Information,12) IOSCO’s Principles on Cross-Border Supervisory Cooperation13) of May 2010, the cross-border regulatory cooperation aspect of the IOSCO 2015 Cross-Border Regulation Task Force Report14) and the work of the Follow-Up Group to address potential regulatory arbitrage). | |
Issuing, creating, and destroying stablecoins | Inability to meet redemptions in stressed conditions For algorithmic arrangements, errors in the issuance or redemption algorithm that impact value | Adequate liquidity (risk) management Liquidity risk management tools (e.g. redemption gates) Certain own funds/liquidity requirements Cyber security and other operational resiliency safeguards AML/CFT and sanctions controls | FATF standards apply to firms “issuing and managing means of payment” or to those who provide “participation in and provision of financial services related to an issuer’s offer and/or sale of a virtual asset”. For GSC arrangements involving banks, the prudential risks and operational resilience vulnerabilities would be subject to the Basel Framework and Principles for the sound management of operational risk. For GSC arrangements deemed to perform systemically important payment system functions or other FMI functions that are systemically important, the PFMI applies. On the basis of a preliminary analysis, some of the most relevant principles regarding these vulnerabilities would be those related to frameworks for comprehensive risk management and settlement. See Annex 4 on CPMI-IOSCO preliminary analysis. Depending on the creation/redemption processes, the IOSCO Principles for the Regulation of Exchange Traded Funds (2013)15) could be relevant. | |
Managing reserve assets | A sharp fall in price and/or liquidity of reserve asset(s) Change in reserve allocation across reserve assets Lack of transparency in the composition of reserve Fraud or mismanagement of the reserve Investment in illiquid assets Significant increase in the price volatility of the reserve assets that cannot be or is not readily managed | Portfolio diversification rules and issuer limits rules Liquidity and other financial risk safeguards Liquidity risk management tools (e.g. redemption gates) Requirements on disclosure of the composition of the assets Disclosure of investment policies Cyber security and other operational resiliency safeguards AML/CFT and sanctions controls | FATF standards apply to those who provide “safekeeping and administration of cash and liquid securities on behalf of other persons”, or “safekeeping and/or administration of virtual assets or instruments enabling control over virtual assets”. For GSC arrangements involving banks, the prudential risks and operational resilience vulnerabilities would be subject to the Basel Framework and Principles for the sound management of operational risk. Depending on its structure, the reserve may engage IOSCO Liquidity Risk Management Recommendations (2018),16) IOSCO Principles for the Regulation of Exchange Traded Funds or IOSCO Policy Recommendations for MMFs (2012). 17) For GSC arrangements deemed to perform systemically important payment system functions or other FMI functions that are systemically important, the PFMI applies. On the basis of a preliminary analysis, some of the most relevant principles regarding these vulnerabilities would be those on custody and investment risks and transparency. See Annex 4 on CPMI-IOSCO preliminary analysis. | |
Providing custody/trust for reserve assets | Custodian failure, cross-border resolution, fraud Liquidity Lack of legal clarity regarding rights to reserve assets, particularly where legal regimes of different jurisdictions are implicated | Segregation requirements/rights for reserve assets Liquidity and other financial risk safeguards Cyber security and other operational resiliency safeguards AML/CFT and sanctions controls | FATF standards apply to those who provide “safekeeping and administration of cash and liquid securities on behalf of other persons” or “safekeeping and/or administration of virtual assets or instruments enabling control over virtual assets”. For GSC arrangements involving banks, the prudential risks and operational resilience vulnerabilities would be subject to the Basel Framework and Principles for the sound management of operational risk. IOSCO Recommendations Regarding the Protection of Client Assets (2013).18) For GSC arrangements deemed to perform systemically important payment system functions or other FMI functions that are systemically important, the PFMI applies. On the basis of a preliminary analysis, some of the most relevant principles regarding these vulnerabilities would be those on custody and investment risks and transparency. See Annex 4 on CPMI-IOSCO preliminary analysis. | |
Operating the infrastructure | Disruption to the mechanism that links the value of the stablecoin and the value of its reserves, for example, a cyber incident Uncertainty on the revocability of the payments GSC ledger compromised due to design flaw, operational (e.g. cyber) incident | Liquidity and other financial risk safeguards Requirements on payments finality Cyber security and other operational resiliency safeguards AML/CFT and sanctions controls | FATF Standards apply to GSC infrastructure if it satisfies the definition of a financial institution or a virtual asset service provider provided in the FATF glossary. For GSC arrangements involving banks, the prudential risks and operational resilience vulnerabilities would be subject to the Basel Framework and Principles for the sound management of operational risk. For GSC arrangements deemed to perform systemically important payment system functions or other FMI functions that are systemically important, the PFMI applies. On the basis of a preliminary analysis, some of the most relevant principles regarding these vulnerabilities would be those on a framework for the comprehensive management of risks and settlement. See Annex 4 on CPMI-IOSCO preliminary analysis. | |
Validating transactions | GSC ledger compromised due to failure of multiple validator nodes | Cyber security and other operational resiliency safeguards AML/CFT and sanctions controls | Depending on the functions they perform, the validator nodes that validate the underlying distributed ledger technology may be VASPs or financial institutions. For GSC arrangements involving banks, the prudential risks and operational resilience vulnerabilities would be subject to the Basel Framework and Principles for the sound management of operational risk. For GSC arrangements deemed to perform systemically important payment system functions or other FMI functions that are systemically important, the PFMI applies. On the basis of a preliminary analysis, some of the most relevant principles regarding this vulnerability would be on operational risk and settlement. See Annex 4 on CPMI-IOSCO preliminary analysis. | |
Storing the private keys providing access to Stablecoins (wallets) | Disruption of a wallet, for example, theft of coins from a digital wallet or operational (e.g. cyber) incident. Direct loss, including by consumers | Liquidity and other financial risk safeguards Cyber security and other operational resiliency safeguards AML/CFT and sanctions controls | FATF Standards apply to all businesses providing custodial wallet services. The FATF Standards do not place explicit obligations on unhosted wallets. For GSC arrangements involving banks, the prudential risks and operational resilience vulnerabilities would be subject to the Basel Framework and Principles for the sound management of operational risk. For GSC arrangements deemed to perform systemically important payment system functions or other FMI functions that are systemically important, the PFMI applies. On the basis of a preliminary analysis, a relevant principle regarding these vulnerabilities would be an operational risk. See Annex 4 on CPMI-IOSCO preliminary analysis. | |
Exchanging, trading, reselling and market making of stablecoins | Withdrawal of liquidity provision by authorized resellers/market makers Disruption of a trading platform. Fraud, market manipulation, unauthorized transactions Cyber incident | Liquidity and other financial risk safeguards Settlement finality requirements Allocation of legal responsibility for unauthorized transactions Cyber security and other operational resiliency safeguards AML/CFT and sanctions controls | FATF Standards apply to all businesses carrying out trading/exchanging activity. The FATF Standards do not explicitly apply to peer-to-peer transactions without the use of a VASP or financial institution. For GSC arrangements involving banks, the prudential risks and operational resilience vulnerabilities would be subject to the Basel Framework and Principles for the sound management of operational risk. For GSC arrangements deemed to perform systemically important payment system functions or other FMI functions that are systemically important, the PFMI applies.

In the following example, the CBDC is modeled as Stablecoins, each account representing an End User. The End Users would actually “own” a wallet that contains account information, where Stablecoins are recorded as a balance that can be added to or subtracted from. For example, a retail purchase would deduct the amount of the purchase from the customer End User's account and add it to the Store's account.
Figure 2 represents a stylized use of a Stablecoin flow of a consumer (End User) buying a product from a retail store.

In this example, the End User's Stablecoin Wallet is used to purchase an item in a store that lists for \$488.78.
Table 5 provides a possible withdrawal from the End User's Stablecoin Wallet. If the withdrawal is accepted by the Stablecoin Wallet's owner, the Stablecoin ownership is changed to the stores.
Item | Quantity | Sum |
---|---|---|
