GENIUS 法案之后：欧洲央行如何看待稳定币

2026 年 5 月 8 日，欧洲央行行长 Christine Lagarde 在演讲中讨论美国 GENIUS 法案之后的稳定币政策争论。

区分两种作用

演讲把货币的跨境使用与可编程技术带来的结算能力分开分析。技术上的潜在收益，并不自动回答应采用哪一种结算资产。

结算基础的选择

演讲关注稳定币的赎回、金融稳定和系统碎片化问题，并讨论以央行货币为基础的公共结算设施，以及代币化存款等工具。

阅读时保留边界

这是欧洲央行的政策观点。不能据此把链上总交易量等同于商户付款量，也不能把技术可行性表述为市场已全面采用。

把资产与处理方式分开评估

可编程支付描述交易条件如何执行，结算资产则回答最终转移的是什么权利。两者可以有不同组合。看到“智能合约支付”时，还需要继续问资产由谁发行、能够向谁兑付。

例如，一笔链上转移完成后，收款人若仍需兑换成银行资金才能支付供应商，就应把兑换环节纳入时间和成本比较。只统计链上确认时间，会漏掉实际经营中的一段路径。

可编程条件不等于自动消除风险

把付款条件写入程序，可以减少一些人工协调，但程序需要获得可靠的信息。例如，是否已经交货、资产是否满足交付条件，可能来自链外业务。信息源或权限设置出现问题时，自动执行也可能把错误更快地传下去。

因此，讨论技术优势时，应同时说明输入信息由谁确认、错误如何暂停或纠正，以及执行结果怎样进入法律和会计记录。这些事项与资产使用哪种币种、由谁发行相互关联，却不能相互替代。

从单笔效率到整个货币网络

欧洲央行的讨论也涉及碎片化：不同私人发行安排若不能按一致条件使用，用户可能面对多个看似等值、实际流动性和赎回路径不同的余额。共享技术标准有助于交换信息，但不会自行统一所有发行人的偿付能力和条款。

理解这层问题，有助于比较公共结算设施、商业银行存款和稳定币的不同角色。最合适的比较对象是一条完整的交易路径，包括资金进入、持有、转移与退出，而不是只对比一段转账动画。

On 8 May 2026, ECB President Christine Lagarde discussed stablecoin policy after the US GENIUS Act.

Separate functions

The speech distinguishes cross-border monetary use from programmable settlement technology. Technological benefits alone do not determine which settlement asset to use.

Settlement choices

It considers redemption risks, fragmentation and public infrastructure anchored in central bank money, alongside instruments such as tokenised deposits.

Reading the evidence

These are policy views. Total on-chain volume should not be treated as merchant payment volume or proof of widespread commercial adoption.

Separate the asset from its processing

Programmability describes how conditions execute; the settlement asset determines what claim changes hands. Ask who issues the asset and who redeems it. If a recipient must convert it into bank money to pay suppliers, that conversion belongs in the time and cost comparison. On-chain confirmation alone leaves part of the business journey unmeasured.

Programmability still depends on trustworthy inputs

Automating a payment condition can reduce coordination work, but the condition may rely on external information such as delivery confirmation. Incorrect inputs or permissions can also transmit an error faster.

An assessment needs to identify who validates that information, how errors are stopped or corrected and how execution connects to legal and accounting records.

Consider the wider monetary network

Fragmentation can leave users with several apparently equivalent balances that have different liquidity and redemption routes. Common technical standards do not equalise issuers’ financial capacity or terms.

This helps explain the comparison between public settlement infrastructure, bank deposits and stablecoins. Evaluate entry, holding, transfer and exit together rather than one transfer step.
