数字欧元零售推出 —— Preparation Phase 2023-2026, 反脱媒设计、e-krona 暂停对比

Wiki route

本词条作为针对 ECB 数字欧元、面向 2026 Preparation-Phase 快照的逐法域深度剖析，归属于 fintech index。它与 CBDC adoption curve 2026 配对以了解四国比较视角、与 CBDC 多层架构概述配对以了解架构语境，并与 CBDC 3 大现役范式配对以了解三范式分类。逐法域同侪参见 e-CNY supply-chain expansion 与 eRupee India pilot status；与 EU 一侧相关的批发型 CBDC 语境（BoF / BdF、BdI 与 Bundesbank 参与）参见 BIS Project Agorá。塑造数字欧元竞争跑道的更宏观 EU stablecoin 监管语境参见 MiCA overview 与 global stablecoin five-pole matrix。

[!info] TL;DR 截至 2026 中期，数字欧元仍处于 Preparation Phase，最初界定为一个 2023-11 至 2025-10 的两年期，如今已延长至 2026-Q4+ 以等待 EU 共同立法结果。无活跃发行、无零售钱包、无活跃商户。具有定义意义的设计选择——经由受监管 PSP 的 两层中介式分销、一个 目前提议为 €3,000-€4,000 的逐人持有限额 并带有指向关联银行账户的 reverse-waterfall、以及零售余额的 零利息——是明确的反脱媒防御。最贴近的警示故事是瑞典 e-krona 项目，Riksbank 在 2024-2025 实际上将其暂停，未对发行作出决定、亦无活跃零售产品，证明了「准备可以无限期延长」。数字欧元的步调不是技术限制；而是一项政策选择，意在等待政治共识的同时保护 €18T+ 的商业银行存款基础。

Matrix A · 法规、监管机构、阶段状态

Item	Detail
Lead authority	European Central Bank (ECB) Governing Council + ECB Executive Board
Legislative basis	Regulation establishing the digital euro — European Commission proposal June 2023; in EU Council + European Parliament co-decision (trilogue)
Investigation Phase	2021-10 → 2023-10 (concluded)
Preparation Phase	2023-11 → originally October 2025; extended into 2026-Q4+ awaiting legislative outcome
Issuance Decision Phase	NOT yet entered as of 2026-05; requires Governing Council decision + legislative basis
Issuance start	Not yet determined; depends on Issuance Decision Phase outcome; earliest realistic 2027-2028
Reporting cadence	ECB publishes quarterly / periodic progress reports on the digital euro project page

ECB 在每一份进展报告中都明确澄清，进入 Preparation Phase 并非发行的决定。发行需要 (i) EU 共同立法法规获得通过，以及 (ii) Governing Council 另行作出启动决定。截至 2026-05 两者都尚未发生。

Matrix B · 设计选择 —— 编码化的反脱媒

Design choice	Detail	Why
Two-tier intermediated	ECB → supervised PSPs (banks, EMIs, payment institutions) → users; ECB does not directly distribute	Preserve commercial-bank role; consistent with [[fintech/cbdc-multi-tier-architecture-three-paradigms
Per-person holding limit	Proposed €3,000-€4,000 per person (subject to legislative decision; not finalised)	Hard cap on aggregate digital-euro balance per person; prevents large-scale conversion of bank deposits into central-bank money
Reverse waterfall	If a payment exceeds the recipient’s holding cap, the surplus auto-transfers to the recipient’s linked commercial-bank account	Removes the holding cap as a UX blocker for individual payments above the cap
Zero interest	The retail digital euro pays no interest	Removes the savings-substitution incentive vs commercial-bank deposits
Online + offline modes	Online mode for general use; offline mode for low-value cash-like P2P	Offline mode replicates cash-like privacy and resilience; online mode supports merchant payments
Privacy tiers	Offline mode = cash-like privacy (no central record of small-value P2P); online mode = supervised PSP visibility with ECB-data-minimisation	Balance privacy expectations vs AML/CFT obligations
Distribution by supervised PSPs only	Wallet provided by banks + supervised PSPs; ECB does not run consumer-facing apps	Forces channel ownership to remain with commercial-bank ecosystem
No interest + no programmability for retail	Explicit rejection of programmable money for retail digital euro	Preserve flexibility; avoid conditional-payment misuse and welfare-state automation framing
Wholesale separate track	Wholesale-CBDC use cases handled via separate Eurosystem exploratory work, not via the retail digital euro	Two distinct tracks; retail is the legislative focus

三个核心的反脱媒参数——holding cap + reverse waterfall + zero interest——是争议最大的公共政策议题。商业银行游说采用低限额（€1,000-€2,500 区间），并强调高限额的系统性风险含义。ECB 已表示对 €3,000-€4,000 感到放心，但尚未最终敲定。立法结果将经由政治协商决定。

Matrix C · Preparation-Phase 工作流

Work-stream	Status (2026-05)
Rulebook drafting	Active; ECB-coordinated working groups with PSP, merchant, and consumer representatives
Technology-vendor selection (framework agreements)	Selected vendors announced; competitive procurement for components (e.g. risk management, fraud prevention, offline payments, app SDK, alias lookup)
Manual + technical testing	Pilot-scale technical testing in closed environments; no public-facing pilot
User-research / consumer focus groups	Active across euro-area Member States
Merchant outreach / acceptance design	Active; payment scheme integration design in flight
Cross-border interoperability design	Discussion of euro-area-wide design; limited engagement with external CBDCs
Legislative dialogue	Active engagement with EU Council and European Parliament; technical advice provided by ECB

Preparation Phase 并非公开试点。它是内部设计与技术供应商工作。最贴近的可比对象是一个处于设计阶段的大型金融基础设施项目，而非一个面向消费者的试验。

Matrix D · 采用指标（最新公开）

Metric	Most-recent public figure
Live retail users	0 (no issuance)
Live merchants	0 (no acceptance)
Cumulative tx volume	0
Cities / coverage	0
Wallet apps live	0
Cross-border CBDC settlement	0
Public pilot participants	0 (Preparation Phase work is internal / vendor-side, not consumer-side)
Vendor framework agreements signed	Multiple component-level (risk management, app SDK, alias lookup, offline payment); selected vendor names announced over 2024-2025

这是唯一一项具有定义意义的事实：截至 2026-05，数字欧元是四个参照 CBDC 项目中唯一一个零售活动为零的。「落后于中国」这一框定在技术上准确，但实质上具有误导性——ECB 已明确表示这是一项政策选择，而非技术差距。

Matrix E · 持有限额与反脱媒防御（深度剖析）

Per-person holding cap proposal (illustrative; not finalised)
       │
       ▼
   €3,000-€4,000  ← Latest publicly-discussed range
       │
       ├── Below cap: digital euro balance held in PSP-provided wallet
       │
       └── Above cap: reverse waterfall to linked commercial-bank account
                       (so payment never blocked from UX perspective)

三层防护：

逐人硬性限额 —— 无论一个人开立多少个钱包，数字欧元持有余额总额均受限（限额是逐人而非逐钱包，需要一次 alias / 身份查询）。
Reverse waterfall —— 一笔会超出限额的付款会将盈余自动路由至关联的商业银行账户。用户仍可发送 / 接收任意金额；仅以数字欧元持有的余额受限。
零利息 —— 完全消除储蓄替代激励；持有数字欧元唯一的经济理由是交易性的，而非储蓄。

ECB 已进行技术分析，表明即便在提议限额的较高端，欧元区数字欧元的总持有量也将仅相当于商业银行存款总额（€18T+）的一个小百分比，而 reverse waterfall 将处理激增动态。商业银行游说团体对此持有异议。立法结果将决定哪一观点占上风。

作为对比，其他三个参照 CBDC 项目中没有任何一个以相同方式将持有限额编码化：

China e-CNY 采用运营商分层限额（低层 ¥10K 交易上限、¥50K 余额；高层 KYC 更高）。
India eRupee 采用日交易的 app 配置限额；无公布的硬性余额上限。
Japan DCJPY 并非 CBDC —— 它是一种代币化银行存款，按构造受 ¥10M 逐银行存款保险限额覆盖。

Matrix F · 分销模式

Layer	Role in distribution
ECB	Issuer (central-bank money); operates the underlying scheme + technical infrastructure
Supervised PSPs (banks, EMIs, payment institutions)	Wallet provision; user onboarding; KYC; user-facing app
Merchants	Accept digital euro payments via payment-scheme integration
Consumers	Hold digital euro in PSP-provided wallet; pay merchants; P2P

分销模式被明确设计为将商业银行保持在消费者关系的中心。这是与中国两层制（赋予 10 家指定运营商分销权限，但由 PBoC 界定运营商）以及与印度两层制（使用 17 家参与银行）之间最大的单一设计差异。EU 的设计对既有商业银行分销渠道的保护程度最高。

与瑞典 e-krona 暂停的对比

由 Sveriges Riksbank 自 2017, 起运行的瑞典 e-krona 项目，是为数字欧元辩论提供借鉴的警示故事。Riksbank 的公开立场从活跃试点（2017-2022）演变为刻意未决的立场（2023-2024），再到实际上的暂停（2024-2025）。关键的公开来源信号：

Riksbank 自 2017 起已跨多个阶段发布 e-krona PoC 报告。
至 2023-2024 ，Riksbank 的公开沟通日益强调发行是一个需要议会决定的政治授权问题，而非仅仅是中央银行的问题。
Riksbank 将重心转向改善既有支付基础设施（RIX-INST 即时支付通道），而非推出 e-krona。
e-krona 讨论相较于 Riksbank 其他工作流实际上已被降级。

对数字欧元的教训：若政治条件不趋于一致，「准备」可以无限期延长。瑞典的经验表明，发行的技术能力已确立完备，但发行的政治-经济决定才是约束性的制约。数字欧元正处于同一轨迹上——技术正在被构建，但发行决定并非 ECB 独自所能定。

Item	EU digital euro	Sweden e-krona
Authority	ECB Governing Council	Sveriges Riksbank
Legislative basis	EU co-decision regulation pending	Swedish parliamentary decision required
Architecture	Two-tier intermediated via supervised PSPs	Two-tier intermediated model (under design)
Holding cap	Proposed €3,000-€4,000	Not finalised; concept design referenced caps
Live retail	None	None
Status (2026-05)	Preparation Phase (extended)	Effectively paused; no issuance decision
Political momentum	Medium-low; commercial banks resist	Low; Riksbank deprioritised
Reason	Anti-disintermediation policy + co-legislative pace	Effective lack of consumer / political pull

与中国和印度的对比是结构性的：在中国，政治授权毋庸置疑，且 PBoC 拥有直接的推行权限；在印度，RBI 拥有机构权限与清晰的技术授权；在 EU，ECB 需要立法同意；在瑞典，Riksbank 需要尚未兑现的议会授权。步调差异是政治性的，而非技术性的。

竞争语境 —— MiCA EMT 与批发型 Eurosystem

数字欧元的竞争跑道受两项平行的 EU 进展所塑造：

MiCA EMT 制度 —— 于 2024-06-30（SC 部分）与 2024-12-30（完整）生效；来自 EU 信贷机构与 EMI 的受监管欧元计价 e-money token (EMT) 已在市场上。EMT 经由私营中介交付了「数字欧元」用例的一部分（可编程欧元支付）。参见 MiCA overview 与 global stablecoin five-pole matrix。
Eurosystem 批发型探索工作 —— 与零售型数字欧元分立；就以中央银行货币进行的批发结算（包括基于 DLT 的结算）开展试验。一些欧元区中央银行（BdF、Banca d’Italia、Bundesbank）参与 BIS Project Agorá 并有各自的 DLT 试点。

这两条互补的轨道意味着就数字货币基础设施整体而言，EU 并未「落后」——它拥有活跃的 MiCA 持牌 EMT 以及活跃的批发型 CBDC 技术工作。被卡住的具体是 零售型 CBDC 发行。正是这一结构性模式，将 EU 的步调与一个真正的技术差距叙事区分开来。

起源与演进

2017-2019    ECB internal work on CBDC; Working Paper series
2020-10      ECB publishes "Report on a digital euro"; consultation launched
2021-10      Investigation Phase begins (2-year)
2023-06      European Commission proposes Regulation establishing the digital euro
2023-10      Investigation Phase concludes; ECB recommends entering Preparation Phase
2023-11      Preparation Phase begins (originally 2-year, to 2025-10)
2024-2025    Vendor framework agreements; rulebook drafting; technical pilots
2025         Preparation Phase progress reports published quarterly / periodically
2025-2026    Preparation Phase extended into 2026-Q4+ awaiting legislative outcome
2026         EU Council + European Parliament continue trilogue on Regulation
2026-05      No issuance decision; Preparation continues
2026-2027    (Anticipated) Issuance Decision Phase entry conditional on legislative outcome
2027-2028    (Earliest realistic) Live retail issuance, conditional on Issuance Decision

模式：每一个重大步骤都取决于多机构的同意。ECB 对该项目拥有机构权限，但对法律基础或约束性政治授权则没有。Riksbank 的 e-krona 经验表明，这种依赖关系可以将时间线无限期拉长。
