CBDC Study Notes: Security, Privacy, and Policy

Security:
- CBDCs should utilize robust encryption techniques to safeguard transactions.
- Central banks must ensure the integrity of the digital currency through secure technology.
- Regular security audits are essential to identify and mitigate vulnerabilities.
Privacy:
- User anonymity varies by design; some CBDCs may allow pseudonymous transactions.
- Privacy measures must balance user confidentiality with anti-money laundering (AML) and combating the financing of terrorism (CFT) regulations.
- Central banks are exploring strategies to protect user data while maintaining compliance.

Direct Control:
- CBDCs allow central banks to implement monetary policy more effectively by providing real-time data.
- They can enhance the transmission mechanism for interest rate changes.
Interest Rates:
- Potential for central banks to set interest rates on CBDCs, influencing saving and spending behavior.
- Passive interest rate adjustments may occur through changes in CBDC supply.
Financial Stability:
- CBDCs could mitigate bank runs by providing a safe and liquid asset.
- They may disrupt traditional banking models, requiring careful management of financial stability risks.

Architecture Models:
- Two main models: Account-based (linked to user identities) and token-based (anonymous transactions).
- Hybrid models may combine elements from both approaches.
Interoperability:
- CBDCs should be designed for seamless interoperability with existing payment systems and currencies.
- Compatibility with international CBDCs is also crucial for cross-border transactions.
Scalability:
- The infrastructure needs to support a high volume of transactions without compromising speed or security.
- Utilizing distributed ledger technology (DLT) may enhance scalability.

Legal Status:
- Clear legal definitions are necessary to establish the status of CBDCs within existing financial regulations.
Regulatory Oversight:
- Central banks will need to develop regulatory frameworks that encompass CBDC issuance, distribution, and use.
- Collaboration with other regulatory bodies is essential to address compliance and oversight challenges.
Consumer Protection:
- Regulations must focus on consumer rights and protections regarding CBDC usage, similar to traditional banking practices.
- Provisions for data protection and user privacy should be integrated into the regulatory framework.

CBDCs require robust encryption to protect transaction data.
Central banks must preserve the integrity of digital currencies through secure technological methods.
Regular security audits are vital to detect and resolve potential vulnerabilities.
User anonymity is contingent on design; some CBDCs may permit pseudonymous transactions.
Privacy mechanisms need to strike a balance between user confidentiality and compliance with anti-money laundering (AML) and combating financing of terrorism (CFT) regulations.
Central banks are researching ways to safeguard user data while adhering to regulatory compliance.

CBDCs enable central banks to apply monetary policy with improved effectiveness by providing real-time economic data.
They can enhance how interest rate changes influence economic activity through the transmission mechanism.
Central banks might set interest rates specifically for CBDCs, affecting consumer saving and spending patterns.
Adjustments in interest rates may also occur passively via fluctuations in CBDC supply.
CBDCs can provide a stable, liquid asset to diminish the risk of bank runs.
Adoption of CBDCs might disrupt traditional banking systems, necessitating careful oversight to maintain financial stability.

Two principal architecture models exist: account-based (user identity linked) and token-based (allowing anonymity).
Hybrid models may integrate features from both the account-based and token-based systems.
CBDCs should facilitate interoperability with existing payment mechanisms and currencies for efficient transactions.
Compatibility with international CBDCs is vital for efficient cross-border transactions.
The CBDC infrastructure must handle a high volume of transactions, ensuring both speed and security are not compromised.
Implementing distributed ledger technology (DLT) can enhance the scalability of CBDC systems.

Clear legal definitions are essential to clarify CBDCs' status within the current financial regulatory landscape.
Central banks are tasked with crafting regulatory frameworks that cover the issuance, distribution, and operational aspects of CBDCs.
Inter-agency collaboration is crucial to manage compliance and oversight complexities, ensuring regulatory effectiveness.
Regulatory measures must prioritize consumer rights and protections within CBDC usage, mirroring those in traditional banking systems.
The regulatory framework should also encompass user privacy and data protection protocols to safeguard consumer interests.
