代幣化銀行存款正逐漸成為一項關鍵創新,無縫結合了傳統金融既有的信任及監管框架,與去中心化金融(DeFi)所帶來的高效和可編程性。
這種融合不僅僅是漸進式的提升,更標誌著受監管金融機構與區塊鏈科技互動的新紀元,專注於解決全球支付、結算系統及金融服務長期存在的低效問題。
當銀行將法定貨幣支持的存款數位化並上鏈,便創建出新一代的混合方案,既保留了傳統銀行體系的穩健,又釋放了過往難以於傳統金融架構中實現的新功能。
這次轉型正值傳統銀行與去中心化協議尋找可持續發展之道,應對日益數位化的經濟環境。
什麼是代幣化銀行存款
代幣化存款是一項獨特的金融創新,與早期的加密貨幣及穩定幣有本質分別。這些數碼代幣由受監管銀行直接發行,每個代幣均對應於發行銀行備付系統中的法定貨幣,具備可驗證的主張權。這種與傳統銀行業的直接連結,使代幣化存款成為金融系統數碼化轉型的重要基建。
與非銀行機構發行的穩定幣不同,代幣化存款與商業銀行體系及支付基礎設施直接整合,同時增添區塊鏈原生功能。這種分別十分重要——這些代幣繼承了發行銀行的監管保障、存款保險及機構穩健,同時獲取區塊鏈的可編程性、透明度以及高效結算等優勢。
代幣化存款的架構,通常由發行銀行或金融機構聯盟維護的私有區塊鏈支撐。每個在此網絡鑄造的代幣,均對應於隔離賬戶中的銀行備付金,創造出可稽核、透明的橋樑,連結傳統資金與其數碼化版本。
此架構可維持全球經濟賴以運作的部分準備金銀行模式,同時令這些備付金可與私人企業區塊鏈及公鏈互動。
傳統金融與去中心化金融的融合
代幣化存款的出現,標誌著傳統銀行與區塊鏈科學之間的重要關係進化。
早期區塊鏈應用多以取代銀行體系為主,著重去中介化及無需信任運作模式。相比之下,代幣化存款則屬融合模式,由傳統金融機構引入區塊鏈技術,以提升現有體系而非完全替代。
這種整合正面回應了金融體系兩端的根本限制。對傳統銀行而言,代幣化存款提供了合規參與區塊鏈生態的途徑,毋須放棄實際運作基礎—部分準備金制度。這令銀行可以在保持監管合規的同時,大幅升級結算基建及擴展服務能力。
對於DeFi協議,代幣化存款則帶來受監管及足額支持的資產,有助降低傳統加密資產的波動及對手風險。這些資產成為去中心化金融中的可靠價值錨點,亦有望推動機構參與。
這種融合特別表現在將兩種金融範疇的優勢結合,創造出更強大能力:
-
法定貨幣備付金取得全年無休的區塊鏈結算能力,消除傳統銀行營業時間及批量處理限制。
-
銀行中介服務經智能合約功能增強,令資金流動可編程並由預設條件控制。
-
令銀行業長年頭痛的手動對賬流程,可被分布式帳本技術下即時自動審計軌跡所取代。
-
備付管理因鏈上可驗證記錄而更透明,補足傳統審計工作。
這種融合創造出能結合傳統銀行穩健合規與區塊鏈自動化和高效結算的全新金融工具,深受金融機構青睞。
轉變全球金融基礎設施
代幣化存款的影響遠超現有銀行產品數碼化。
這些新型工具正在促成金融不同範疇的根本變革,包括批發銀行、零售支付至跨境交易。
革新批發銀行及結算流程
目前,代幣化存款最即時的影響要數批發銀行操作,高效率遲遲未能突破,雖然科技大幅進步。摩根大通、 高盛、BNY Mellon等主要金融機構,率先推出代幣化存款項目,實際改變了銀行間結算流程。
摩根大通 Onyx 平台是此領域的先驅之一,自推出以來,該平台促成逾三千億美元的代幣化交易,集中於回購協議(repo)及證券結算。
透過將現金及證券代幣化並運作於共同的區塊鏈基建上,Onyx將結算時間由傳統的T+2(兩天)縮短至T+0(同日),同時大幅節省營運成本。
這些能力更不僅是加速結算。代幣化存款令現金管理策略更創新,包括:
-
日內流動性最佳化,讓銀行靈活短暫調配過剩備付金,減低繁複操作。
-
智能合約自動調整抵押按市價,令擔保品管理隨市場變動而自動處理。
-
動態庫房營運可依預設條件自動響應,無需人手介入。
促進跨境支付創新
跨境支付亦是代幣化存款展現轉型潛力的另一範疇。傳統代理銀行需數日結算、費用無常且對賬複雜。代幣化存款透過銀行間直通互換,無需代理關係,有效解決上述問題。
由新加坡金融管理局聯同多間環球大行帶領的「Project Guardian」多階段代幣化資產探索,於此領域取得亮眼成果。
於2023及2024年試點期間,該項目成功將新加坡元和日圓存款代幣化,並通過去中心化流動性池實現貨幣互換。
成果顯著:結算時間較傳統代理銀行減近六成,交易成本最多降低五成。更重要的是,該模式在市場壓力場景下展示了自動流動性管理的韌性。
條件式支付與可編程貨幣
除優化現有流程外,代幣化存款亦憑智能合約賦予資金嶄新編程能力。智能合約可對資金流動加設何時、如何、何種情況下轉賬等條款,成為全新商業管理工具。
於貿易金融,代幣化存款正被用作自動履行的托管安排。結合認證數碼文件及供應鏈追蹤系統後,智能合約可在貨物到達並達標時自動付款,減少信用證等繁瑣文件,減低全球貿易摩擦。
於房地產交易,智能合約實現可編程托管,讓交易雙方毋須傳統中介即可獲得資金保障。合同可核實產權轉移文件後才釋款給賣方,加快交割程序並減輕風險。
企業銀行界近年亦採用代幣化存款進行精細資金管理,包括:
-
自動在帳戶間調撥超額資金,依預設金額及時間設定;
-
落實「即時資金」至營運帳戶,提升流動資本運用效率;
-
條件式付款可與發票審批流程及項目進度付款掛鉤。
此類能力使財資操作達至自動化及高精準,同時全面遵從企業管治及監管。
機構DeFi參與及市場整合
代幣化存款同時 creating pathways for regulated financial institutions to participate in decentralized finance ecosystems that were previously inaccessible due to regulatory constraints and risk management concerns.
為受監管金融機構創建途徑,讓他們可以參與去中心化金融(DeFi)生態系統,而這些生態系統以往因監管限制及風險管理考慮而無法進入。
By introducing bank-issued tokens with clear regulatory status into these systems, institutions can access the efficiency of DeFi protocols while maintaining compliance with their regulatory obligations.
透過在這些系統中引入具明確監管地位的銀行發行代幣,機構可以在保持合規的同時,體驗DeFi協議的高效率。
Several major banks have begun exploring integrations between their tokenized deposits and established DeFi lending protocols. JPMorgan's collaboration with Aave Arc represents a pioneering example, with the bank exploring how tokenized dollar deposits could interact with permissioned versions of the popular lending protocol.
多間大型銀行已開始研究把其代幣化存款與既有的DeFi借貸協議整合。摩根大通與Aave Arc的合作就是一個先例,該行正在探索代幣化美元存款如何與這個受權限管理的主流借貸協議互動。
Similar initiatives involving Goldman Sachs and Compound Treasury point toward growing institutional interest in these hybrid models.
高盛和Compound Treasury等類似計劃,顯示機構對這類混合模式的興趣日益增加。
These integrations create significant opportunities for both traditional institutions and DeFi protocols. Banks gain access to more efficient lending markets and yield generation opportunities, while DeFi protocols benefit from increased liquidity and institutional participation. The result is a more robust financial ecosystem that combines the best elements of both centralized and decentralized models.
這些整合為傳統機構及DeFi協議雙方帶來重大機遇。銀行可以參與更高效的借貸市場和收益機會,而DeFi協議則受惠於流動性提升和機構參與,從而打造出結合中心化和去中心化優點的更強大金融生態圈。
This merger is further accelerated by the development of specialized infrastructure designed specifically for institutional DeFi participation. Platforms like Fireblocks and Copper provide institutional-grade custody solutions that support tokenized deposits, while compliance-focused protocols like TRM Labs and Chainalysis ensure these interactions meet regulatory requirements.
這種融合進一步受到專為機構級DeFi參與而設的基礎設施所推動。Fireblocks和Copper等平台為代幣化存款提供機構級託管服務,而TRM Labs及Chainalysis等著重合規的平台則確保相關互動符合監管要求。
Technical Architecture and Implementation Models
技術架構與實現模式
The technical implementation of tokenized deposits varies significantly across institutions, reflecting different strategic priorities, regulatory environments, and technology strategies. However, several common architectural patterns have emerged that illustrate how these systems typically function.
代幣化存款的技術實現因應不同機構的策略重點、監管環境及科技策略而有很大差異。不過,已出現數種常見的架構模式,展示這類系統的典型運作方式。
Most tokenized deposit implementations utilize permissioned blockchain networks rather than public chains, at least for their core infrastructure. These networks provide greater control over participant access and transaction validation, addressing regulatory concerns around AML/KYC compliance and transaction privacy. JP Morgan's Onyx platform, for example, operates on a modified version of Ethereum called Quorum that incorporates enhanced privacy features and permissioned validation.
大部分代幣化存款方案都採用私有區塊鏈(即受權限管理的區塊鏈)作為核心基建,而非公有鏈。這些網絡容許參與者及交易驗證有更多控制權,回應有關反洗黑錢(AML)、認識你的客戶(KYC)和交易私隱的監管憂慮。例如,摩根大通的Onyx平台運作於名為Quorum的以太坊改版本,加入強化私隱和權限驗證。
Interoperability between these permissioned networks and public blockchains represents a crucial design consideration. Several approaches have emerged to address this challenge:
這些權限網絡與公有區塊鏈的互通性,是設計上的重要考慮因素。目前已有數種方案嘗試解決這個難題:
-
Bridge mechanisms that allow tokenized deposits to move between permissioned and public networks under controlled conditions;
-
跨鏈橋接機制,容許代幣化存款在受控條件下於私有和公有區塊鏈間轉移;
-
Layer-2 scaling solutions that maintain settlement finality on a private network while posting cryptographic proofs to public chains;
-
二層擴展方案,於私有鏈內保障最終結算,同時將加密證明發佈到公鏈上;
-
Hybrid models where certain transaction types remain within permissioned environments while others interact with public infrastructure.
-
混合模式,一部分交易保留於私有環境內,另一部分則跟公有基建互動。
The tokenization process itself typically involves several key components:
代幣化流程本身通常涉及數個主要組成部分:
-
A secure minting mechanism tied directly to traditional banking systems that creates new tokens only when corresponding fiat deposits are verified;
-
一個直接連接傳統銀行系統的安全鑄幣機制,只有當相應法幣存款確實到位時方可創建新代幣;
-
A robust custody solution that secures the private keys controlling token issuance and movement;
-
穩健的託管方案,用以保障控制代幣發行和流轉的私鑰安全;
-
Real-time reconciliation systems that ensure the token supply always matches the underlying deposits;
-
實時對賬系統,確保代幣供應總額與實際存款金額匹配;
-
Compliance frameworks that enforce regulatory requirements across all token movements.
-
具規範性的合規框架,確保所有代幣流通行為均符合監管要求。
Settlement finality - the irreversible transfer of ownership - represents another crucial technical consideration in these systems.
結算最終性,即資產所有權無可逆轉地轉移,在這些系統中亦是關鍵的技術考慮。
While public blockchains achieve settlement finality through consensus mechanisms like proof-of-work or proof-of-stake, permissioned networks typically rely on more traditional Byzantine Fault Tolerant consensus algorithms that prioritize deterministic finality over decentralization.
公有區塊鏈一般透過如工作量證明(PoW)或權益證明(PoS)等共識機制實現結算最終性,但私有鏈多數採用拜占庭容錯(BFT)共識演算法,優先保障確定性結算,而非極度去中心化。
Regulatory Frameworks and Compliance Considerations
監管框架及合規考慮
The regulatory landscape for tokenized deposits continues to evolve, with different jurisdictions taking varied approaches to classification and oversight. Unlike cryptocurrencies and stablecoins, which often occupy ambiguous regulatory territory, tokenized deposits generally fall under existing banking regulations as they represent direct claims against regulated institutions.
代幣化存款的監管格局仍在發展中,各地區在定義及監管上採取不同做法。與加密貨幣及穩定幣常處於監管灰色地帶不同,代幣化存款一般受現行銀行監管制度規範,因其代表對受規管機構的直接債權。
In the United States, the Office of the Comptroller of the Currency (OCC) has provided guidance confirming that national banks may provide cryptocurrency custody services and use blockchain networks for permitted banking functions, including deposit-taking activities.
在美國,貨幣監理署(OCC)已發出指引,確認國家銀行可提供加密貨幣託管服務,並可使用區塊鏈網絡作合資格的銀行業務,包括吸收存款。
This guidance has created a foundation for tokenized deposit implementation, though institutions must still navigate complex requirements around consumer protection, reserve management, and anti-money laundering compliance.
該指引為推動代幣化存款打下基礎,但機構仍須應對在消費者保障、儲備管理及反洗黑錢(AML)合規上的各種複雜要求。
The European Union's Markets in Crypto-Assets (MiCA) regulation specifically addresses electronic money tokens (EMTs), a classification that encompasses many tokenized deposit implementations. MiCA establishes clear requirements for issuers of such tokens, including reserve management, redemption rights, and consumer protection measures.
歐盟的加密資產市場(MiCA)監管方案,亦針對電子貨幣代幣(EMTs)作出規範,而這一分類涵蓋不少代幣化存款實現。MiCA為相關代幣發行方設立明確要求,包括儲備管理、贖回權利和消費者保護措施。
Singapore has emerged as a global leader in tokenized deposit regulation through its Payment Services Act and collaborative industry initiatives like Project Guardian. These frameworks provide clear guidance on reserve requirements, consumer protection measures, and operational standards for tokenized deposits.
新加坡亦通過《支付服務法》和業界合作項目(如Project Guardian),成為全球在代幣化存款監管方面的先驅。這些框架對儲備要求、消費者保障及營運標準作出明確指引。
Despite these advances, significant regulatory challenges remain:
儘管取得上述進展,仍然面對不少監管挑戰︰
-
Jurisdictional variations in digital asset classifications create compliance complexity for cross-border implementations;
-
各地數字資產分類不一,導致跨境落地時的合規複雜性高;
-
Uncertainty around the application of securities laws to certain tokenized deposit features, particularly when these tokens incorporate yield-generating mechanisms;
-
有關証券法是否適用於含收益元素的代幣化存款等特性,仍存不少不確定性;
-
Questions about deposit insurance application to tokenized representations of bank deposits, especially in cross-border scenarios.
-
如何在跨境情境中將存款保險覆蓋範圍延伸到代幣化銀行存款,亦有待釐清。
Financial institutions implementing tokenized deposits must navigate these considerations through robust compliance frameworks that often exceed standard requirements for traditional banking products. These frameworks typically include:
金融機構要落實代幣化存款時,須透過一套比傳統銀行產品更嚴格的合規框架去處理上述問題。這些框架通常涵蓋︰
-
Enhanced KYC/AML procedures specific to blockchain-based transactions;
-
加強針對區塊鏈交易的KYC/AML程序;
-
Comprehensive risk assessments addressing both traditional banking risks and blockchain-specific considerations;
-
全面風險評估,兼顧傳統銀行及區塊鏈相關風險因素;
-
Regular reporting to regulators on reserve management and token circulation;
-
就儲備管理及代幣流通定期向監管部門報告;
-
Clear redemption procedures ensuring depositors can convert tokens back to traditional deposits when desired.
-
明確贖回程序,保證存戶隨時可把代幣兌回傳統存款。
Security Considerations and Risk Management
安全考慮與風險管理
Security remains a paramount concern in tokenized deposit implementations, given both the novelty of these systems and the significant value they control.
安全是代幣化存款實現過程中最重要的關注點,尤其考慮到這些系統的新穎性及其所涉及的巨大價值。
While blockchain technology offers inherent security advantages through cryptographic verification and immutable transaction records, it also introduces new attack vectors and operational risks that institutions must carefully manage.
雖然區塊鏈天生具備密碼學驗證和不可篡改交易記錄等安全優勢,但同時也引入了新的攻擊缺口和營運風險,需要機構仔細管理。
Private key security represents perhaps the most critical risk management challenge in these systems. Unlike traditional banking systems where authentication relies on centralized credentials, blockchain networks use cryptographic private keys to authorize transactions.
私鑰安全或許是這些系統中最關鍵的風險管理挑戰之一。與傳統銀行依賴中心化憑證作認證不同,區塊鏈網絡通過加密私鑰來授權交易。
The compromise of these keys could potentially lead to unauthorized token creation or movement, creating significant financial and reputational risks.
一旦私鑰被盜取,可能導致未經授權發幣或資產轉移,帶來重大的財務及聲譽損失。
To address these concerns, institutions implementing tokenized deposits typically employ sophisticated key management solutions including:
為應對這些風險,落實代幣化存款的機構通常會採用先進的私鑰管理方案,例如︰
-
Hardware security modules (HSMs) that store private keys in tamper-resistant hardware;
-
硬件安全模組(HSM),將私鑰存放於防篡改硬件之中;
-
Multi-signature authorization schemes requiring multiple approvals for sensitive operations;
-
多重簽署認證機制,敏感操作須有多方授權;
-
Key sharding techniques that distribute key fragments across different security domains;
-
私鑰分片技術,把私鑰碎片分布於不同保安域;
-
Comprehensive access control frameworks limiting which personnel can initiate specific transaction types.
-
嚴格存取權限架構,約束不同人員可執行的操作類型。
Smart contract vulnerabilities represent another significant security consideration. As the $1.8 billion in cross-chain exploits during 2023-2024 demonstrated, even well-audited smart contracts can contain subtle vulnerabilities that malicious actors may exploit. Financial institutions must implement rigorous code review, formal verification, and ongoing security monitoring to mitigate these risks.
智能合約的漏洞亦是一項重大安全議題。正如2023至2024年間發生的18億美元跨鏈攻擊事件所揭示,即使經過審計的智能合約仍可能藏有潛在漏洞,容易被有心人利用。金融機構必須透過嚴格的程式碼審查、形式化驗證及持續安全監控來減低這些風險。
Operational resilience considerations also differ from traditional banking infrastructure. While blockchain networks typically offer greater uptime than conventional banking systems, they introduce different failure modes that require specialized monitoring and incident response capabilities.
營運彈性亦和傳統銀行基建不同。雖然區塊鏈網絡通常較傳統系統有更長正常運作時間,但它們呈現出不同的失效模式,需要針對性的監控及應變機制。
Leading institutions in this space have developed comprehensive resilience frameworks addressing node failure scenarios, consensus disruptions, and network partition events.
行業領先機構已建立周全的彈性框架,針對節點故障、共識中斷及網絡分割等情況作出應對。
The Future Landscape: Adoption Trajectories and Market Evolution
未來展望︰應用路徑與市場演變
As tokenized deposits continue to mature, several key trends are shaping their development trajectory and potential market impact:
隨著代幣化存款日臻成熟,數個主要趨勢正影響其發展路向及潛在市場影響︰
Expanding Beyond USD and Major Currencies
擴展超越美元及主流貨幣
While early tokenized deposit implementations have focused primarily on major currencies like USD, EUR, and JPY, financial institutions are increasingly exploring tokenization of additional fiat currencies.
初期的代幣化存款多集中於美元、歐元、日圓等主流貨幣,但金融機構現正加緊發掘更多法定貨幣之代幣化潛力。
This expansion addresses growing demand for efficient cross-border settlement solutions involving emerging market currencies that currently face significant friction in traditional correspondent banking channels.
這一發展回應了目前新興市場貨幣跨境結算效率低下、傳統代理銀行渠道障礙重重的市場需求。
HSBC's recent tokenization of Hong Kong Dollar deposits represents a notable example of this trend, enabling more efficient settlement between HKD and other major currencies. Similar implementations for Singapore Dollar, Brazilian Real, and Mexican Peso are under development across various banking consortia.
滙豐最近對港元存款代幣化就是其中一個明顯例子,有助於港元與其他主流貨幣之間更高效結算。新加坡元、巴西雷亞爾及墨西哥披索等亦正由多個銀行聯盟進行相關技術開發。
###Integration with Tokenized Securities and Assets
將代幣化存款同其他代幣化金融工具融合,正係創造強大嘅新型市場基建。
當現金同證券都以數碼代幣形式存喺兼容嘅區塊鏈網絡上,完全新嘅交易模式就變得可能。
新加坡嘅 Project Guardian 已經示範咗,代幣化存款可以點樣同代幣化政府債券互動,實現無需傳統結算中介嘅“原子即時交收”(atomic delivery-versus-payment settlement)。
同類型嘅方案,而家喺企業債券、股票,甚至地產同私人股權等另類資產上都處於唔同階段嘅開發中。
Institutional DeFi and Yield Generation
隨住監管框架成熟,金融機構開始探索將代幣化存款喺去中心化金融(DeFi)生態系統中應用,方式越來越多樣化。呢啲應用不止於簡單參與借貸市場,仲包括:
- 利用自動化收益優化策略,根據現時利率,將代幣化存款分配到唔同獲批准嘅借貸協議;
- 為受監管嘅去中心化交易所提供流動性,便利合規嘅數碼資產交易;
- 參與專為低波動性、深度流動性環境設計嘅機構級自動做市商。
呢個發展標誌住 DeFi 生態圈重大成熟,因為傳統金融機構將佢哋嘅風險管理經驗同合規能力引入一度只屬於零售市場嘅領域。
Redefining the Boundaries of Banking
代幣化銀行存款代表住銀行服務同區塊鏈科技融合一個好深遠嘅進化。呢種做法唔係將分布式賬本科技作為傳統銀行嘅替代品,而係利用區塊鏈獨特嘅優勢,提升傳統銀行功能,同時保住合規同機構穩定性。
呢類系統結合咗傳統銀行嘅信任同監管清晰度,仲有區塊鏈科技嘅效率、可編程性同結算保障。呢種混合模式解決咗傳統金融(如結算延誤、操作效率低)同去中心化金融(如監管不明、機構參與有限)嘅不少限制。
隨住呢啲系統繼續成熟,佢哋好大機會會重塑全球金融基建重要部分,特別係批發銀行業、跨境交易同資產服務。佢哋嘅發展唔係要取代傳統銀行,而係令傳統銀行進化成更高效率、更透明、同更可編程嘅新形態。
能夠順利過渡嘅金融機構,將會喺重要市場轉型中佔領先機;但係一旦落後,隨住客戶對代幣化存款帶來嘅效率同功能越嚟越有期望,可能會喺競爭中愈來愈被動。
呢種機構級信任加上區塊鏈效率嘅融合,的確重新定義咗全球金融嘅可能性,為未來創建一個更連接、更高效、更具創新能力嘅金融體系。
