The 2025 Tariff-War Storm: A Retrospective

The 2025 Tariff-War Storm: A Retrospective is a panoramic analytical framework covering Trump’s launch of the reciprocal tariff war on April 2, 2025, and its suspension after just seven days on April 9 (the “18 harrowing hours”). The core thesis: what forced Trump’s abrupt reversal was not China’s counter-measures, EU pressure, domestic political advisers, or Dimon’s television speech, but rather the US Treasury market’s three consecutive days (April 7, 8, 9) of “US equities + US Treasuries + US dollar triple kill” plus a massive deleveraging storm — with approximately $950 bi ll i o nin T re a s u ryc a s h - f u t u res ba s i s - t r a d e p os i t i o n s (corres p o n d in g t o$ 2.5 trillion in leveraged assets), risk-parity fund algorithms simultaneously deleveraging, and the Treasury market facing potential collapse on April 9 itself if the pause had not been announced. The framework also puts forward the methodological principle that “fast risk variables precede slow political variables,” and situates the episode within the strategic backdrop of the Mar-a-Lago Accord (three axes: tariffs + weak dollar + 100-year zero-coupon century bonds), concluding that a second wave of the storm is inevitable.

Core Thesis and Three Hidden Lines

The framework exposes a fact hidden by the mainstream narrative: Trump launched the “reciprocal tariff war” on April 2, 2025, and called it off just seven days later on April 9 in the “18 harrowing hours” pause of 90 days — what forced him to reverse course was not China’s counter-measures, not the EU’s united resistance, not domestic political advisers, not Dimon’s television speech; the essence was that the US Treasury market experienced three consecutive days (April 7, 8, 9) of “US equities + US Treasuries + US dollar triple kill” plus a massive deleveraging storm plus a chain detonation of Treasury cash-futures basis-trade positions (~$950 billion) — had Trump not immediately announced a pause, the Treasury market could have collapsed on April 9 itself.

The storm was not over — in late May 2025 the 10-year/30-year Treasury yields climbed again; the framework’s core argument is: the US Treasury market (not equities, not tariffs, not politics) is the true variable for judging the limits of Trump’s tariff policy; as long as the transmission chain of the deleveraging storm has not been fully severed, similar events will recur.

Beneath this main line, three complementary hidden lines must be understood:

Hidden Line A — Treasury deleveraging storm (basis trades + risk-parity funds + long-bond term-premium risk): After the rate-hike cycle ended, sustained high rates + widening fiscal deficits + QT wind-down = Treasury cash-futures basis-trade positions grew to approximately ** $950 bi ll i o n * * (N Y F e d L ib er t y St ree t, Dece mb er 2024 es t ima t e), corres p o n d in g t o$ 2.5 trillion in leveraged assets; risk-parity hedge funds (Bridgewater All-Weather / AQR / various passive-replication strategies) also accumulated Treasury long positions to historical highs; any large VIX/MOVE spike triggers algorithmic simultaneous deleveraging → Treasuries sold → yields rise → selling spiral. The three consecutive “triple kills” of April 7/8/9 are instances of this mechanism. See Repo and Shadow Money for the general account of the primary dealer storm-eye and collateral logic.
Hidden Line B — fast risk variables vs. slow variables (financial markets are the true variable for judging policy limits): Analyzing the tariff war should not proceed from politics/economics/public opinion (these are all “slow variables,” taking months to years to take effect); one should look directly at financial market risk variables (volatility, yields, liquidity, cross-currency basis) — these are “fast variables” that can detonate within hours. “The wind rises from the tip of a blade of grass” — fast variables issue warnings ahead of slow variables. This is the core methodological contribution of this framework.
Hidden Line C — the Mar-a-Lago Accord = the strategic backdrop of the tariff war: Stephen Miran (Trump’s chief economic adviser), November 2024 paper A User’s Guide to Restructuring the Global Trading System — the core idea is to use tariffs + currency reset (dollar depreciation) + debt restructuring (100-year zero-coupon century bonds) as three axes to resolve the US twin deficits. The tariff war is not an isolated policy; it is the first cut of a larger restructuring plan; but the first cut directly challenged Treasury market stability and ignited the deleveraging — forcing a plan adjustment. See The Dollar Circulation System for the structural role of US Treasuries as global collateral.

The framework’s core warning: the April 2025 deleveraging storm was only a prelude — the Mar-a-Lago Accord’s two main lines of “dollar depreciation + debt restructuring” are still advancing; as long as the problems with risk-parity funds + basis-trade positions + long-bond term-premium risk are not fundamentally resolved, the next similar storm (possibly triggered by a new round of tariffs / surging fiscal deficits / a Fed independence crisis) will inevitably erupt.

Ten Propositions

The real reason Trump called off the tariff war on April 9 was the imminent collapse of the US Treasury market, not China’s counter-measures / Dimon’s speech / political pressure. Key evidence chain: three consecutive “triple kills” on April 7/8/9; on the morning of April 9 (9:00–13:00) Treasury yields surged intraday, long-bond 20–30 year above 5%; at 13:00 on April 9 Trump suddenly announced the 90-day pause — even his aides were caught off guard, showing an extremely hasty decision process; the morning window of April 9 (9:00–12:00) was the critical window of persuasion: Dimon’s 8:00 AM television speech was only the opening act, but the true turning point was Treasury Secretary Bessent’s midday White House meeting, where he walked Trump through the technical details of the Treasury market.
“The wind rises from the tip of a blade of grass” — financial market fast risk variables are the true variables for judging tariff-war limits, more important than employment / inflation / GDP / political opinion (slow variables). The tariff war’s critical decisions do not depend on economist consensus; they depend on whether markets can collapse before the policy takes effect. Any major policy’s limit boundary is discovered first by financial market risk variables.
**Treasury basis-trade positions ~ $950 bi ll i o na re t hi ss t or m^{'} s " p o w d er k e g "— r i s k - p a r i t y an d h e d g e f u n d s u se 90$ 950 billion, corresponding to ~ $2.5 t r i ll i o n + in l e v er a g e d a sse t s; f a r l a r g er t han t h e$ 750 billion at the time of the March 2020 storm. This is the extension of the March 2020 reasoning chain to 2025 — same mechanism, larger scale.
The “US equities + US Treasuries + US dollar triple kill” is a dual signal of liquidity exhaustion + overseas de-dollarization — an extreme combination not seen before. Under normal conditions: equities fall → Treasuries rise (safe-haven) → dollar rises (safe-haven); the “triple kill” appearing on April 8, 2025 meant: (a) equity panic (VIX surging to 50+); (b) Treasuries sold rather than bought — safe haven failed; (c) dollar depreciated rather than appreciated — overseas funds losing confidence in US assets. This is the “enhanced version” of the March 2020 triple kill — risk premium repriced across US assets as a whole.
The Mar-a-Lago Accord is the strategic backdrop of the tariff war — three axes: tariffs + currency reset (weak dollar) + debt restructuring (100-year zero-coupon century bonds). Miran’s November 2024 paper systematically argues: use tariffs to pressure trading partners into currency negotiations + use security protection as leverage to force allies to hold century bonds + use dollar depreciation to resolve the twin deficits. The tariff war is not an isolated policy; it is a “test-first-cut” of the larger restructuring plan.
The process by which Trump made the “reciprocal tariff” decision was absurd — using the outrageous formula “bilateral trade deficit / total imports × 50%” (some countries minimum 10%, China maximum 145%) — market shock was not due to the tariffs themselves, but because the calculation method exposed “decision-making irrationality.” This narrative crisis accelerated overseas investors’ distrust of dollar assets.
The synchronized deleveraging algorithms of risk-parity hedge funds is the core transmission of Treasury deleveraging — VIX surges → algorithms automatically reallocate by “inverse volatility / risk budget” → all strategies simultaneously sell. Unlike March 2020: in April 2025 the Treasury basis positions accumulated during the rate-hike cycle were larger, the interest-rate environment imposed higher “costs” on algorithms (financing costs 5%+), and deleveraging speed was faster.
At 13:00 on April 9, Trump’s Truth Social announcement of “90-day pause” + “China excluded at 145%” — the market instantly reversed: S&P rebounded 9.5% (third-largest single-day gain in history). But a narrative reset is not equivalent to risk eliminated: after April 9, the dollar continued depreciating / long-bond yields did not return to April 1 levels / cross-border capital outflows from US assets continued — the market was merely anesthetized by the “pause.”
Late May 2025: 10-year/30-year Treasury yields climbing again + credit-default swap (CDS) anomalies = signs of a second wave. The 30-year broke 5% again at end of May (new high); Moody’s downgraded US sovereign credit on May 16 (AAA→Aa1) → the US lost its final AAA from any of the three major rating agencies (S&P downgraded in 2011; Fitch downgraded in August 2023). This means the April 9 halt only kicked the powder-keg’s fuse aside without defusing it.
The next tariff-war storm’s transmission path will be shorter and more violent — if the Mar-a-Lago Accord continues advancing “dollar depreciation + debt restructuring,” it will inevitably hit Treasury market limits again. Potential triggers: the May 12 US-China tariff exemption expiring and re-escalating / a new deficit bill / further erosion of Fed independence / coordinated foreign central bank reduction of US Treasury holdings. To judge the next wave, one must use the 12 indicators in §5 + the three-flow joint observation rule.

Key Data Anchors

April 2 reciprocal tariff list: baseline tariff 10% (minimum); Vietnam 46%, Cambodia 49%, Thailand 36%; China total 145% (10% baseline + 34% reciprocal + prior 20% + additional April 9 increment); calculation method = bilateral trade deficit / total imports × 50% (absurd formula); targeting approximately 60 countries.
Market performance April 2–9:
- April 3/4: US equities evaporate $6.6 trillion; S&P −10.5% (two-day cumulative); Dow −7.9%; Nasdaq enters bear market
- April 7: continued decline; VIX breaks 50; Asian markets follow (Nikkei −7.8%)
- April 8: US equities + Treasuries + dollar “triple kill” — S&P −1.6% / 10Y yield +18bp / dollar −0.5%
- April 9 morning: 30-year Treasury intraday exceeds 5%; 10-year exceeds 4.5%
- April 9 13:00: Trump Truth Social announces 90-day pause
- April 9 close: S&P +9.5% (third-largest single-day gain in history)
- April 10: rally holds; China tariffs continue escalating
Treasury basis-trade position sizes:
- NY Fed Liberty Street, December 2024 estimate: cash-futures basis-trade nominal size ~ $950 bi ll i o n, corres p o n d in g t o$ 2.5 trillion leveraged assets
- Risk-parity fund AUM estimated $450-700 bi ll i o n (in c l u d in g B r i d g e w a t er A ll - W e a t h er$ 150 billion, AQR ~$28 billion, passive-replication strategies + sovereign fund embedded risk parity)
- April 2025 deleveraging estimated ~30–40% of positions force-closed
Key personnel April 9 decision chain:
- 8:00 EST: Jamie Dimon (JPMorgan CEO) CNBC TV: “US recession probability rising”
- 9:00–12:00: Bessent (Scott Bessent, Treasury Secretary) at White House meeting with Trump, presenting Treasury market technical details
- 9:33: Trump posts on social media “NOW IS A GREAT TIME TO BUY” — signaling the decision was essentially made
- 13:00: Trump Truth Social suddenly announces “90-day pause”
Evidence of cross-border capital outflows from US assets: DXY dollar index fell ~3% cumulative from April 2 to April 9 (rare); US Treasury overseas holdings Q1 2025 (TIC data): Japan continued modest reduction / China flat / Europe adding but net increment smaller than deficit; gold price broke $3,200/oz on April 9, setting a new high.
May 12 US-China Geneva talks: China 145%→30%, US 84%→10%; exemption lasting through August 12; later extended to November 9.
May 16 Moody’s US sovereign downgrade: Moody’s from AAA to Aa1 (Moody’s was the last of the three major agencies to maintain US AAA; S&P downgraded in 2011; Fitch downgraded in August 2023); rationale = continued widening fiscal deficit + policy uncertainty.
Late May Treasury yield new highs: 30-year breaks 5.10% (highest since 2024); 10-year breaks 4.55%; TIPS real yield 30-year >2.5%.
Mar-a-Lago Accord core: Stephen Miran, November 2024 paper A User’s Guide to Restructuring the Global Trading System (Hudson Bay Capital); three axes: (1) tariffs reshape trade (2) weak dollar policy (3) century bonds (100-year zero-coupon bonds, forcing allies to hold as the price of security protection); analogous to a reverse operation combining the 1985 Plaza Accord and 1944 Bretton Woods.
Key figures: Trump; Scott Bessent (Treasury Secretary, hedge fund background); Stephen Miran (CEA chair); Howard Lutnick (Commerce Secretary); Peter Navarro (chief trade adviser, hardline tariff faction); Jamie Dimon (JPMorgan CEO).

Compiler’s Perspective

This section is the compiler’s perspective: the entry’s coordinates within the broader system and its connections, distinct from the framework body above.

Coordinates: event retrospective × Shu × Why It Is So. This framework answers “why the April 9 halt happened at that exact moment,” not “how to respond to the tariff war”; the answer is positioned at the mechanism level of the Treasury market, not at any political negotiation outcome.

Position in the framework lineage: The 2025 Gold Storm: A Retrospective is the physical-gold version of the concurrent events, sharing the “dollar system cracks” backdrop with this entry, but with different mechanisms: gold was a physical squeeze (paper claims > deliverable physical), while Treasuries involved basis-trade deleveraging ( $950 bi ll i o nin p os i t i o n s f orce d t oc l ose) . [[T h e 2020 F inan c ia lSt or m : A R e t ros p ec t i v e]] i s t h e 2025 u p g r a d e d v ers i o n o f t h er i s k - p a r i t y f u n d + a l g or i t hm d e l e v er a g in g m ec hani s min H i dd e n L in e A : s am e m ec hani s m, b u t ba s i s p os i t i o n se x p an d e df ro m$ 750 billion to ~$950 billion, and financing costs rose from near-zero to 5%+. The Dollar Circulation System provides the structural backdrop of Treasuries as global collateral — this structure is why the “triple kill” signal (Treasuries sold rather than bought) was different from normal.

Soul-level connection: connects to the world is a grand improv show — break the mold, don’t take mainstream values as gospel — the reciprocal tariff calculation method (trade deficit / total imports × 50%) was exposed by economists worldwide on April 2 itself, who could immediately compute the deviation from any theoretical benchmark; the mainstream cognitive framework attributes the April 9 halt to “political pressure,” “the other side’s concession,” or “Dimon’s persuasion,” because these fit the “rational negotiation” logic of slow-variable narratives. In reality, at 8:00 AM when Dimon was speaking and before Bessent entered the White House, markets were already watching the 30-year Treasury break 5% intraday and MOVE approach 140 — these fast variables were speaking, while the political narrative was a post-hoc explanation. Those waiting for the halt signal using the “who persuaded whom” framework had no confirming signal before April 9 at 13:00; those using the fast-variable framework already knew by 9:00 AM when Treasuries broke 5% that the probability of a halt was extremely high.

Proprietary increment: the precise chronology of the April 9 decision chain (8:00 Dimon TV → 9:33 Trump posts “NOW IS A GREAT TIME TO BUY” → 9:00–12:00 Bessent’s White House meeting presenting Treasury technical details → 13:00 pause announced) provides one verifiable causal thread: the policy halt occurred within four hours of US financial markets opening, not after any political negotiation response arrived. China’s official position, EU stance, and Congressional reactions all came after April 9 at 13:00 — they cannot have been the triggers.
