The Dollar System at the Margin: A Credit-and-Institution Reading

美元体系行至边际：一份货币信用分析

Core thesis / 核心判断

The dollar-centered system is not on the verge of a sudden collapse; it is undergoing a slow-motion transition from "unipolar privilege" to "first-among-equals multipolarity." This is a gradual erosion of monetary credit and a rebuilding of settlement plumbing—not a breakpoint event.

美元体系不会骤然崩塌，而是正从“单极特权”向“多极并存下的第一货币”慢速过渡。这是货币信用的渐次磨损与清算制度的重构，而非断点式危机。

1. Credit anchor: still load-bearing, but the concrete is cracking

一、信用锚：仍承重，但混凝土已开裂

The post-1945 dollar order rests on three legs: Fed credibility, Treasury liquidity, and the invoice-pricing habit in commodities. All three remain standing in 2026—yet none is as solid as in 2010.

1945年后的美元秩序立在三根柱子上：美联储信用、美债流动性、大宗商品美元定价惯性。到2026年三根都在，但没一根像2010年那么结实。

• Reserve share / 储备份额：IMF COFER 2026Q1 puts the dollar at 57.13%​ of allocated FX reserves, up from 56.42% in 2025Q4—but roughly half the uptick is exchange-rate valuation, not fresh central-bank buying. The 1999 peak was ~71%; the curve is a 20-year slope, not a cliff.

• Payment pipe / 支付管道：SWIFT 2026/06 — USD 50.10%, EUR 21.88%, RMB 3.10% (back to No.5). USD dipped below 50% in Jan-2026 then bounced; the 50% line is now a wobble zone, not a fortress wall.

• Fiscal Triffin / 财政特里芬难题：Federal debt crossed 39tninMar−2026∗∗andisbrushing∗∗40tn by Aug-2026; debt/GDP ≈123%. FY2026 net interest >$1tn, exceeding the defense budget; CBO sees public-debt/GDP at 120% by 2036. The US still borrows in its own currency, so default risk is near zero—but inflation-tax risk​ (monetizing debt via a dovish Fed) is the real credit leak.

  美国仍用本币借债，技术违约概率近零；但“用通胀税稀释债务”的政治激励，才是信用锚真正的渗漏点。

The 2022 freeze of Russian FX reserves did what no spreadsheet could: it converted "US Treasuries are risk-free" into "US Treasuries are risk-free unless you displease Washington." That is a qualitative shift in perceived credit, not a number move.

2022年冻结俄外储做了一件模型做不到的事：把“美债无风险”改写成“美债无风险，除非你得罪华盛顿”。这是信用认知的质性偏移，不是数值跳动。

2. Plumbing diversification: bypass lanes, not a new highway

二、管道分流：在修匝道，不是在盖新主干道

De-dollarization in 2026 is non-confrontational, non-substitutional, layered.

2026年的去美元化是“非对抗、非替代、分层推进”的。

• BRICS Pay​ went live in 2026, stitching CIPS + SPFS + Pix for local-currency settlement; Saudi oil-to-China RMB settlement ~41%, Iran-to-China 100% RMB, Russia-China >95% local currency.

• CIPS​ scaled to 194 direct + 1,597 indirect participants (Mar-2026 daily ~¥920bn; single-day >¥1.22tn in Apr-2026), 126 jurisdictions.

• Gold​ is the quiet winner: official gold value eclipsed overseas-held Treasuries in 2025 (~3.93tnvs3.88tn); central banks bought 244t net in 2026Q1 alone.

But none of these clears the three hurdles a true reserve substitute needs: (i) deep risk-free asset market, (ii) 24/7 repo/collateral liquidity, (iii) predictable legal finality. CIPS settles RMB; gold yields nothing; BRICS Unit is a prototype. The dollar’s moat is not the flag, it is the plumbing depth.

但这些都没跨过“储备替代品”的三道门槛：有深度的无风险资产市场、全天候回购/抵押流动性、可预期的法治终局性。CIPS 只清人民币，黄金不生息，金砖 Unit 只是原型。美元的护城河不是国旗，是管道深度。

3. Scenario map: from “dollar ends” to “dollar dilutes”

三、情景映射：从“美元终结”到“美元稀释”

The popular binary—collapse vs eternal hegemony—is analytically lazy. The real variable is θ (theta), the speed of marginal credit discounting: how fast the world prices US fiscal risk into the term premium without exiting the system.

“崩塌 VS 永恒霸权”这种二分法是懒人框架。真变量是 θ：边际信用折价的速率——世界以多快速度把美国财政风险计入期限溢价，却不退出系统。

4. Asset-market translation

四、翻译到资产价格

• UST / 美债：Still the only elephant in the room. Yields stay biased higher (30Y ~5.0–5.3%) because supply outruns organic foreign demand; hold for liquidity, shorten duration for credit.

  美债仍是房间里唯一的大象。供给跑赢自发外资需求，收益率偏上行；留底仓为流动性，降久期为信用。

• Gold / 黄金：Structural bid from central banks is the cleanest expression of “I don’t trust the dollar anchor but I still mark in USD.” 央行买金是“不信美元锚、但仍用美元记账”的最干净表达。

• RMB assets / 人民币资产：CIPS + bilateral swap lines lift settlement share faster than reserve share; the gap between transaction use and store-of-value use stays wide until capital account opens further.

  人民币交易份额跑得比储备份额快；在资本账户进一步打开前，“交易用”和“储值用”之间会一直有裂缝。

• EM equities / 新兴股：A multipolar pipe cuts USD-liquidity whiplash risk, but raises FX-basis complexity. Not a free put on dollar weakness.

  多极管道降低美元流动性鞭梢效应，但抬高套息基差复杂度，不是“做空美元就赚”的免费期权。

5. Bottom line in one breath

五、延展

The dollar’s credit is being discounted at the margin, not revoked; the system is shifting from “the dollar is the system” to “the dollar is the largest node in a fragmented system.” Betting on a 202X collapse is a tail trade with negative carry. Betting on gradual dilution is the actual regime.

美元信用正在被边际折价，而非被吊销；体系正从“美元即系统”走向“美元是碎片化系统里最大的节点”。押注某年美元归零是负carry的尾部交易，押注缓慢稀释才是真regime。
