BIS Says Stablecoins Fail Core “Money” Tests for Payments
The Bank for International Settlements (BIS) says today’s stablecoins do not meet the core requirements of money as a widely accepted payment instrument. BIS General Manager Pablo Hernández de Cos made the case at a Bank of Japan seminar in Tokyo, arguing that existing stablecoin designs lack two key properties: “singleness” and “interoperability.”
Singleness means different forms of money should be interchangeable at par across intermediaries. De Cos warned that stablecoins can face confidence shocks that widen discounts, leading users to refuse certain tokens. Interoperability requires users to send and receive funds smoothly across platforms and networks. But stablecoins are issued across multiple blockchains, and even the same token on different chains is not interoperable by default.
De Cos said these gaps undermine the network effects needed for money: more acceptance should drive wider use, but under current designs stablecoins could remain a “niche” payment instrument. He also noted potential benefits for cross-border payments, while cautioning that fiat-tied crypto can affect credit supply, financial stability, and monetary and fiscal policy.
Market context: despite broader digital-asset weakness since Q4 2025, the stablecoin market has held up better. Stablecoin total market value is cited as above $320 billion, a new all-time high, according to DefiLlama. Bitcoin was mentioned around $75,000, up more than 6% on the week.

BIS对稳定币“货币属性”提出制度性质疑，通常会带来偏谨慎的舆论影响。德科斯强调稳定币在“单一性”和“互操作性”上的不足，可能限制其作为主流支付工具的扩张路径；同时，他还点到稳定币可能对信贷投放与金融稳定、货币与财政政策产生外溢影响。此类来自顶级央行体系的表态，往往会让交易者预期后续监管框架更趋严格，从而在短期对稳定币相关资产的风险偏好形成约束。
但从文章给出的市场数据看，稳定币市场并未明显崩塌：总市值仍被指在3200亿美元以上并创历史新高。这说明即便存在“功能性/制度性”争议，需求侧（跨境、对冲、清算替代等）仍在支撑资金流。相比之下，真正的交易影响可能更体现在“支付叙事的边际降温”和“监管预期的上调”，而非立刻引发流动性出清。
对短期而言，交易者可能更关注稳定币发行链路、互操作能力、以及监管合规成本的预期变化；对长期而言，市场可能会向更接近BIS口径的产品形态演进（如更强的互操作安排、更清晰的储备与赎回机制）。整体因此更接近中性：偏监管利空叙事，但市场规模韧性较强，难以直接推导出持续的价格单边方向。
