Stablecoins Aren’t Dollar Alternatives — IMF Data Shows They’re Treasury-Wrapped Dollars

ccn.com发布于2026-02-15更新于2026-02-15

文章摘要

The IMF's analysis reveals that stablecoins, particularly dollar-pegged ones like USDT and USDC, are not independent alternatives to traditional finance but are increasingly backed by short-term U.S. Treasury bills and repo agreements. This makes them a "private distribution layer for dollars" rather than a replacement. The market is highly concentrated, with USDT and USDC comprising 90% of issuance. As stablecoin reserves scale in Treasuries, they begin to influence key financial systems, including money markets and Treasury yields. A BIS study notes that stablecoin flows can cause small but measurable moves in three-month Treasury bill yields. Regulatory attention is growing, with U.S. policies focusing on payment frameworks, while China bans yuan-linked stablecoins, and Europe expresses concerns about dollar dominance in this space. Ultimately, stablecoins are becoming integral to dollar distribution, raising issues around banking competition and financial stability.

Key Takeaways

The IMF said stablecoin usage is still driven mainly by crypto trading, even as payment use cases grow.
Reserve disclosures show issuers leaning into Treasury bills and Treasury repo, making stablecoins look increasingly money-market-adjacent.
A BIS paper links stablecoin flows to small but measurable moves in three-month Treasury bill yields, tying crypto demand to core dollar-market pricing.

Stablecoins are still marketed as crypto’s escape from traditional finance: borderless money, always on, independent of banks.

In a recent paper, the International Monetary Fund offered a cooler read.

“The stablecoin market is increasingly built on short-term U.S. government debt, turning the “stablecoin era” into a private distribution layer for dollars, not a replacement for them,” it wrote.

The IMF’s data also shows how concentrated that layer has become. Dollar-pegged stablecoins represent 97% of issuance, and USDT and USDC account for about 90% of the market, according to the paper.

That matters because once the biggest tokens warehouse Treasury bills and Treasury-collateralized repo at scale, stablecoins start touching the same systems policymakers care about: deposit competition, money markets, cross-border flows, and financial stability.

“Crypto Dollars” That Look Like Money-Market Plumbing

The IMF documents a steady migration toward safer, more liquid backing assets, especially short-term U.S. Treasuries and repo structures collateralized by Treasuries.

Circle frames USDC in similar terms on its transparency disclosures, describing reserves held in cash, short-dated U.S. Treasuries, and overnight U.S. Treasury repurchase agreements, with portfolio reporting available through BlackRock.

Visa’s economic research puts numbers on the same pattern: by mid-2025, it highlighted USDC reserves heavily allocated to reverse repos and Treasury bills, with a smaller share in bank deposits.

Tether has leaned into the scale story as well. In a January 2026 update, Tether said it ended 2025 with record $141 billion exposure to U.S. Treasuries (direct and indirect) and $6.3 billion in excess reserves.

Stablecoins Are Now Big Enough To Nudge Treasury Pricing

Once stablecoin reserves sit in Treasury bills and Treasury repo, the next question is whether stablecoin demand can move those markets.

A BIS working paper using daily data from 2021–2025 finds that a two-standard-deviation inflow into stablecoins is associated with a 2–2.5 basis point drop in three-month Treasury yields within about 10 days, with limited spillover to longer maturities.

It also finds asymmetric effects: outflows raise yields by more than inflows lower them.

That does not mean stablecoins “set rates.” It does suggest they are no longer just a crypto convenience. They are becoming a marginal buyer of the safest collateral in dollar finance.

If stablecoins keep scaling, heavy demand for T-bills could steepen the curve by pulling down front-end yields, while stress-driven redemptions could push yields up faster in a selloff.

That scenario depends on adoption and market structure, but it is exactly the kind of plumbing effect regulators monitor.

Policy Is Converging on a “Payments Money” Frame

U.S. policy is converging on payments framing.

The GENIUS Act establishes a federal framework for “payment stablecoins,” defining issuer categories and oversight processes.

The core promise, stable value and liquidity, depends on rules around backing assets, disclosures, and supervision.

But the fight has shifted to incentives.

A White House meeting between banking and crypto groups ended without agreement, with banks pushing to restrict interest-like rewards tied to stablecoins, because “yield” is where stablecoins start competing directly with deposits.

Standard Chartered has put a headline number on the threat: it warned U.S. banks could lose up to five hundred billion dollars in deposits by 2028 if stablecoins accelerate as a mainstream cash alternative.

China Draws a Red Line on Yuan Stablecoins

China is drawing a hard sovereignty line.

In a Feb. 6 joint notice, the People’s Bank of China and other agencies reiterated that crypto-related business is illegal in China and barred unauthorized issuance of offshore stablecoins pegged to the renminbi (yuan).

The move frames stablecoins as a monetary-control issue, not just a payments product.

Europe Is Watching The Dollar Rails Harden

Europe’s central bank has been unusually direct : dollar stablecoins are “reshaping global finance,” and without a response, European monetary sovereignty and financial stability could erode. The ECB also notes that the market is overwhelmingly dollar-based (it cites about 99%), while euro stablecoins remain marginal.

In other words: if stablecoins are becoming default “internet cash,” Europe worries it will be internet cash in dollars.

Bottom Line

The IMF’s message is less about hype than taxonomy: stablecoins are increasingly Treasury-wrapped dollars on new rails, with benefits for speed and access, but with real consequences for banking competition, capital flows, and market plumbing.

The question now is not whether stablecoins “beat” the dollar. It’s who gets to operate, and regulate, the dollar’s next distribution network.

发消息就能转币？Telegram 今夏要给 10 亿用户「塞」一个加密钱包

Telegram创始人Pavel Durov宣布，将于今年夏季在所有Telegram应用中内置原生的非托管Gram钱包，面向其超过10亿月活用户提供零手续费的即时加密货币转账服务。Durov称这将是“人类历史上最大规模的非托管加密钱包部署”。此次推出的钱包与Telegram内已有的第三方托管钱包@wallet不同，由Telegram官方开发，采用非托管模式，用户直接控制私钥。消息公布后，TON区块链原生代币GRAM价格上涨约8%。这一举措是Telegram自2018年启动TON项目以来叙事的最新进展。2026年，Durov重新掌控TON网络并推动“复兴”路线图，钱包内置是其中一步。当前，超级应用的支付竞争加剧，马斯克的X Money已推出法币功能，Meta计划整合稳定币支付。相比之下，Telegram选择了加密原生路线，凭借其庞大的用户基础和社区亲和力进行差异化竞争。然而，该承诺仍缺乏关键细节，如具体上线时间、“零手续费”的技术实现方案，以及如何面向海量普通用户进行私钥管理教育等。

Hyperliquid的HIP-4提案推动HYPE质押，长期信心增长

Hyperliquid提出HIP-4升级提案，旨在引入无需许可的结果市场，将协议从永续合约扩展到更广泛的基础设施层，允许开发者在平台上构建应用。部署新市场需质押50万HYPE代币，并通过验证者模板和削减规则保障质量。该转变使Hyperliquid从产品构建者转向基础设施提供者。市场对此反应积极，HYPE的正面情绪升至近一个月第二高位。投资者长期信心增强，表现为一位大额盈利交易员选择质押价值约1550万美元的HYPE而非获利了结。目前总质押量已达约4.387亿枚代币，占总供应量的43.9%，持续质押减少了流通供应并增强了网络安全。衍生品市场方面，未平仓合约突破110亿美元，资金费率平衡且清算有限，表明交易者在增加头寸时杠杆使用克制。协议收入、总锁仓价值和治理参与度均在增长，显示生态发展超越单纯价格波动。未来趋势能否持续将取决于用户采用和升级执行情况。整体而言，质押增长与健康的市场结构共同支撑了Hyperliquid的长期发展前景。

汇旺倒台7个月后，东南亚担保平台大洗牌

素有“东南亚支付宝”之称的汇旺支付于去年12月倒台，但其留下的市场迅速被其他担保平台瓜分，拉开了新一轮洗牌。新币、领航（老虎）、金贝（金博）、达利（天成）和福利来等平台走到台前，它们继承了汇旺的双重角色：一方面为黑灰产、洗钱提供便利，另一方面扮演“信任中介”。汇旺的崩塌源于其背后金主太子集团覆灭，美国司法部没收了集团实控人陈志价值约150亿美元的比特币。汇旺累计处理资金超千亿美元，曾是最大的在线非法市场。其继任者们各有所长：新币平台总收入已超16亿美元；领航担保公然为绑架交易提供担保；金博主打网络博彩；达利继承了汇旺部分业务；福利来则与缅北诈骗园区关联密切。这些平台深植于东南亚的诈骗、博彩、人口贩卖等黑灰产网络，所谓的“东南亚支付宝”并非美誉，而是畸形金融生态的缩影。尽管目前风光，但其游走于犯罪边缘的业务注定难以长久。

风光难再，加密 VC 正在经历什么？

加密专项风投基金正面临结构性挑战与行业转型。头部机构如Paradigm已完成跨赛道扩张，将资金投向AI、机器人等领域，并淡化加密标签；Framework Ventures等也纷纷拓宽投资边界。2026年一季度纯加密新基金设立数量创2020年来新低，显示赛道热度下降。这种转变源于加密技术逐步成熟并融入传统金融体系，导致专项基金的信息壁垒瓦解。传统巨头如贝莱德、Stripe已直接布局加密底层设施，无需依赖专项基金的专业知识。同时，风投行业呈现“杠铃式分化”：巨型综合基金与小规模精品基金存活，中等规模的加密专项基金则陷入困境，因其管理规模难以仅靠加密赛道实现回报要求。基金出资方（LP）的行为变化也驱动转型。由于近年加密基金回报不佳，而AI赛道吸纳大量资金，管理人为满足LP需求转向多领域投资。这对加密创业者构成挑战：在综合基金内部，加密项目需与AI等项目竞争资源；且综合基金通常不愿投资虽对生态重要但商业回报不明确的基础设施项目。未来，“加密投资人”可能像“互联网投资人”一样成为过时概念。加密将逐渐成为底层金融基础设施，而非独立投资赛道。行业格局预计将持续重构：大额成长轮投资由综合基金主导，前沿实验性项目则由小型专项基金支持。一些新兴加密项目已通过社区募资而非传统风投启动，标志着行业融资方式的演变。

当共识越来越快，年轻投资人在赌什么？

本文探讨了在AI、机器人、商业航天等硬科技快速发展的背景下，年轻投资人的投资逻辑变化与趋势。技术从实验室到产业的周期缩短，传统财务模型和经验已不足够，投资人需深入理解技术并在共识形成前作出判断。文章基于WAIC发布的“阿尔法α青年投资领袖”榜单，提炼出四大趋势：一、AI正从数字世界进入物理世界，投资重点转向具身智能、机器人和端侧设备，强调规模化交付能力而非演示效果。二、大模型红利尚未完全释放，竞争焦点转向构建“智能飞轮”，即通过数据闭环和用户反馈实现自我增强的系统。三、面对高质量数据瓶颈，投资关注强化学习、自我博弈等新范式，科学基础模型成为潜在方向。四、在商业航天、量子计算等深水区，需要更耐心的资本，投资于可能重塑未来产业基础的长周期技术。总体而言，新一代投资人正更早、更深地介入技术，在不确定性中寻找长期价值。
