Introduction
The rapid advancement of technology and the digital economy has made financial digitization an irreversible trend. Asset tokenization and programmable technologies are reshaping monetary payment ecosystems, presenting both opportunities and challenges. This article explores the Bank for International Settlements' (BIS) perspectives on the future of digital currencies, focusing on tokenized assets and their integration into monetary systems.
Evolution of Virtual Assets: Bitcoin and Stablecoins
Bitcoin's Limitations
- Volatility: Bitcoin's extreme price fluctuations render it unsuitable as a stable medium of exchange, functioning more as a speculative asset.
- Market Decline: Global virtual asset market capitalization peaked at $2.97 trillion in November 2021 but plummeted to $1.62 trillion by December 2023 due to events like the UST collapse and FTX bankruptcy.
Stablecoins: Progress and Pitfalls
- Payment Potential: Pegged to fiat currencies like the USD, stablecoins (e.g., USDT, USDC) aim to mitigate volatility but remain unregulated and vulnerable to crises (e.g., SVB collapse).
- Lack of Stability: No stablecoin has achieved perfect price stability, highlighting reliance on central bank-issued currencies for trust.
Rise of Real-World Asset (RWA) Tokenization
What is RWA Tokenization?
- Definition: Linking economic value and rights of real-world assets (e.g., bonds, real estate, carbon credits) to blockchain-based tokens.
- Growth: Despite broader crypto market declines, RWA tokenization surged from $800 million in January 2023 to $5.5 billion by December 2023.
Models of Tokenization
- Off-Chain Tokenization: Assets (e.g., gold) are custodied offline, with tokens representing ownership on-chain.
- On-Chain Native Tokenization: Tokens (e.g., digital bonds) are issued directly on-chain, embodying intrinsic value without offline backing.
Case Studies
| Asset Type | Example |
|---|---|
| Gold | Tether Gold (XAUt): Each token represents 1 oz of physical gold stored in Switzerland. |
| Real Estate | RealT: Tokenized U.S. property ownership enabling fractional investment and rental income. |
| Art | Picasso’s Fillette au Béret tokenized by Sygnum Bank for fractional ownership. |
| Bonds | Siemens issued €60M tokenized bonds on Polygon blockchain. |
Advantages and Risks of RWA Tokenization
Benefits
- Lower Barriers: Enables fractional ownership of high-value assets like art or real estate.
- Enhanced Liquidity: Facilitates 24/7 cross-border trading and atomic settlements via smart contracts.
- Transparency: Immutable blockchain records improve auditability and reduce fraud.
Challenges
- Regulatory Fragmentation: Lack of global standards complicates compliance.
- Legal Uncertainty: Ambiguities around smart contract enforceability and asset rights.
- Systemic Risks: Potential contagion from crypto market shocks to traditional finance.
Deposit Tokens: A New Frontier in Payments
How They Work
- Definition: Digital representations of bank deposits, offering instant, programmable settlements.
- Use Cases: Cross-border payments (e.g., JPMorgan’s JPM Coin) and trade finance (e.g., Citi Token Services).
Advantages Over Stablecoins
- Safety: Banks’ adherence to capital/reserve requirements enhances stability.
- Efficiency: Eliminates intermediaries in transactions, reducing costs and delays.
The Indispensable Role of Central Bank Money
CBDCs as the Anchor
- Trust Backbone: Central bank digital currencies (CBDCs) ensure monetary singleness and finality in settlements.
- Unified Ledger: BIS proposes integrating CBDCs with tokenized assets via programmable platforms to enable atomic settlements.
Global Pilots
- UK: Exploring a digital pound for monetary unity.
- South Korea: Testing wholesale CBDCs for interbank tokenized asset清算.
- Switzerland: SNB’s pilot for CBDC-based institutional清算.
Conclusion and Future Outlook
- RWA Tokenization: Merging physical and virtual markets,但 requires robust监管 frameworks.
- Deposit Tokens: A safer alternative to stablecoins, yet dependent on CBDCs for trust.
- CBDCs: Critical for未来 monetary systems, ensuring stability amid tokenization trends.

FAQs
Q: How does RWA tokenization differ from traditional securitization?
A: Tokenization leverages blockchain for fractional ownership and 24/7 trading, unlike conventional securitization’s reliance on centralized intermediaries.
Q: Are deposit tokens considered money?
A: Not yet. They represent bank liabilities and lack monetary singleness without CBDC integration.
Q: What risks do CBDCs address?
A: CBDCs mitigate信用 and流动性 risks in tokenized systems while ensuring支付 finality.
