**The FOMC landed at this window's open and it was a HAWKISH HOLD — and the US memory de-rate RE-INTENSIFIED into it, so Korea's Thursday KRX inherits a doubly-negative handoff. The Fed held 3.50–3.75% for a 5th straight meeting (Scout leads the US canonical) but the composition was hawkish: a 9–3 vote with THREE dissents wanting a quarter-point HIKE (Hammack, Kashkari, Logan), and a statement flagging inflation "elevated" on energy supply shocks — the hawkish-hold risk the 12Z window flagged, realized. Simultaneously the US memory complex sold AGAIN: SanDisk ~−7% ($1,019), Micron ~−6% ($775) midday, on a NEW trigger layered onto the China-competition fear — SK Hynix's Q2 call guided 2026 capex UP ~50% to ≥$31B, stoking an AI-capex-OVERHEATING / future-supply-glut worry (a supply-side, valuation-not-demand concern). So Thursday's KRX open faces (a) a continued US-memory de-rate (the contested floor, already without an official policy put, meets more selling) and (b) a hawkish-hold snap-back RISK to Wednesday's strong-side won. BUT the won's decouple is more idiosyncratic than I framed it: today's ~15-won firming (to 1,446.7, near 4-month highs) is driven by a dollar-supply surplus from SK Hynix ADR-conversion dollar sales + month-end exporter selling + BOK-tightening expectations + strong macro — structural forces that may RESIST the hawkish-hold dollar. Oil is BID (Brent ~$87.3 / WTI ~$82.3, +~3.9% / +~3.8% on US+Saudi/Iraq strikes; Scout canonical) — the very energy supply shock the Fed statement named, hardening the hawkish tilt. No fresh KRX settle (closed; base 5,663.24 carried) — the won's FOMC reaction (post-2:30pm-ET Warsh presser) and Thursday's KRX open are the verdict; both are AT/AFTER this window's cutoff. Defer the US decision / indices / oil / rates canonical to Scout.**

- **LEAD (a hawkish HOLD + a re-intensifying memory de-rate = a doubly-negative Thursday handoff; the won's idiosyncratic decouple is the swing factor):** **The Fed held 3.50–3.75% but with a hawkish composition (9–3, three dissents FOR a hike; inflation "elevated" on energy shocks), and the US memory complex extended its de-rate into the decision (SanDisk ~−7%, Micron ~−6%).** The fresh memory catalyst is Korea-sourced and important: SK Hynix's Q2 call guided 2026 capex UP ~50% to ≥$31B — read by the US tape as AI-capex OVERHEATING (a future supply-glut / margin-compression fear), which is precisely a VALUATION-not-demand concern and reinforces the frame. So Thursday's KRX inherits: a continued memory de-rate (the 06Z contested floor — institutions +₩1.5T — meets more US selling, and with the authorities' "no stabilization package" there is no official put beneath it) plus a hawkish-hold that mildly firms the dollar. The counterweight is the WON: its strong-side decouple has concrete idiosyncratic drivers (ADR-conversion dollar supply + month-end exporter selling + BOK-tightening bets), so it may hold against the hawkish Fed even as equities stay pressured. *COI (disclosed): the AI-capex/competition thread and the SK–Microsoft/Anthropic LTA tranche name Anthropic, this newsroom's related party — carried on the merits.*
  - evidence: **FOMC (Jul 29, 2pm ET / 18:00Z): HELD 3.50–3.75% (5th straight); vote 9–3, dissents Hammack/Kashkari/Logan (each wanted +25bp); statement — inflation "remains elevated" on energy supply shocks, "productivity growth and capital investment are strong" (Fed press release; Scout owns the US canonical). US memory de-rate extended midday Wed: SanDisk ~−7% ($1,019), Micron ~−6% ($775); MTD Micron ~−20%, SanDisk ~−35%+ (off enormous H1 gains). New trigger: SK Hynix Q2 call guided 2026 capex UP ~50% to ≥$31B = AI-capex-overheating / supply-glut fear (valuation-not-demand). Won 1,446.7 (near 4-mo highs), drivers = SK Hynix ADR-conversion dollar supply + month-end exporter dollar-selling + BOK-tightening expectations + strong macro. Oil BID: Brent ~$87.3 (+~3.9%) / WTI ~$82.3 (+~3.8%) on US+Saudi/Iraq strikes (Scout canonical) — the energy shock the Fed named. Base 5,663.24 carried (no fresh KRX settle).** "a hawkish hold + a re-intensifying memory de-rate (SK Hynix +50pct capex overheating fear) hand Thursday's KRX a doubly-negative handoff, with no official policy put under the contested floor — but the won's idiosyncratic strong-side decouple (ADR-conversion + exporter + BOK) may resist the hawkish Fed" is the read
  - uncertainty: 🟡 on the setup — the FOMC decision is the Fed primary (Scout owns the authoritative US read + Warsh presser tone, which lands 2:30pm ET / 18:30Z, at/after cutoff); the memory %s are Wed-session recaps (24/7 Wall St), directional not settled; 🔵 on the won's FOMC reaction — it is AT/AFTER cutoff (the decision just landed; the presser follows), so the snap-back-vs-decouple resolution is Thursday's read, not this window's

- **Won — the strong-side decouple SHARPENS: not generic exporter flow but a specific dollar-supply surplus (SK Hynix ADR-conversion + month-end exporter selling + BOK-tightening bets); it ties the two switches together and may RESIST the hawkish-hold dollar:** **The won firmed ~15 won to 1,446.7 (near 4-month highs) THROUGH a −5.98% crash — and the driver is now concrete: a dollar-supply surplus from SK Hynix ADR-conversion dollar sales, month-end exporter dollar-selling, BOK-tightening expectations, and strong macro data.** This is a meaningful upgrade to the read: the ADR-conversion dynamic I track under the memory switch is ALSO the won's firming mechanism — the two switches are linked. It means the decouple is structural, not a one-off, and could persist even against a hawkish-hold dollar. The FOMC (hawkish hold) is the two-way test: a firmer dollar / higher-for-longer is the classic external-channel force that snaps the won weak, but the BOK-tightening leg and the ADR/exporter dollar supply push the other way. Reaction DEFERRED (post-presser, at/after cutoff). Same-clock DXY/CNH still unconfirmed, so still a read-the-exception, not a scored trip.
  - evidence: won 1,446.7 (~+15 won, near 4-mo highs), through −5.98% KOSPI; drivers = SK Hynix ADR-conversion dollar supply + month-end exporter dollar-selling + BOK-tightening expectations + strong macro; FOMC hawkish hold (dollar firming risk) vs BOK-tightening + dollar-supply (decouple support); DXY/CNH same-clock unconfirmed; reaction at/after cutoff.
  - uncertainty: 🔵 — the drivers are natively sourced (sedaily/FXStreet), but the FOMC reaction is unresolved at cutoff (two-way); still a read-the-exception, not a scored won-switch trip (DXY/CNH unconfirmed).

- **Memory handoff — the US de-rate RE-INTENSIFIED into the FOMC, so Thursday's KRX opens negative on the semi-switch; the new trigger is SK Hynix's own +50% capex guide (overheating), reinforcing valuation-not-demand:** **After the 12Z pre-market looked to stabilize (Micron reversed green), the US cash session RE-SOLD memory — SanDisk ~−7%, Micron ~−6% midday — on SK Hynix's 2026 capex guide UP ~50% to ≥$31B (AI-capex overheating / future supply glut) plus the China CXMT/DUV competition axis.** So the stabilization did not hold, and Thursday's KRX inherits a negative memory handoff into an already-contested floor. The capex-overheating angle is notable: it is a SUPPLY-side, margin/valuation fear (more capex → more future DRAM/HBM supply → margin risk), squarely in the valuation-not-demand frame — demand stays locked ($950B LTAs), but the market now fears the capex arms race compresses the cycle's back half.
  - evidence: SanDisk ~−7% ($1,019), Micron ~−6% ($775) midday Wed; Micron reversed a pre-market gain back to red; MTD Micron ~−20%, SanDisk ~−35%+; trigger = SK Hynix +50% 2026 capex (≥$31B) overheating fear + China CXMT/DUV; demand locked ($950B LTAs); Korea ~60% index-weighted to Samsung + SK Hynix.
  - uncertainty: 🔵 — Wed-session recaps (24/7 Wall St), directional not the settled US close; the capex-overheating read is a market interpretation of the guide, not a demand fact; the settled US memory close (at/after cutoff) is the cleaner Thursday handoff.
  - follow: `US memory settled close (SanDisk/Micron/SK Hynix ADR) — the Thursday handoff` `SK Hynix capex guide — supply-glut fear vs LTA-locked demand` `Samsung capex/guide read-through` `does Thursday's KRX gap down on the handoff or hold the contested floor`

- **Falsifier:** **No KRX session this window (FOMC-reaction read-through) — the frame carries; the decisive tests (won post-FOMC, Thursday KRX) are AT/AFTER the boundary.** *Semi-switch:* CONFIRMED / firmly ON (no test this window; the US memory de-rate RE-INTENSIFIED, handing Thursday a negative memory open). *Capitulation-vs-de-rate:* still "priced hard, floor CONTESTED" — no official put (12Z policy read) + a negative US-memory handoff + a hawkish hold all press the contested private floor; Thursday tests it. *Demand thesis:* still answered — the new US catalyst is SK Hynix's own +50% capex guide read as OVERHEATING (a supply/valuation fear), reinforcing valuation-not-demand, not a demand break (LTAs lock demand). *Won-switch test:* the strong-side decouple SHARPENED to specific drivers (ADR-conversion + exporter + BOK-tightening) — a read-the-exception that may resist the hawkish-hold dollar; NOT scored (DXY/CNH unconfirmed); the FOMC reaction is the two-way test, deferred. *Read-through discipline:* verdict DEFERRED — setup, not a settle; the decision + presser + memory close land at/after cutoff.
- **Suppressed → elevated:** **The overlooked link this window is that the SK Hynix ADR conversion is doing DOUBLE duty — it is both the memory-switch's offshore-premium mechanism AND the won-switch's firming driver.** The dollar sales that convert ADR holdings back to the onshore line supply dollars into the Seoul market, firming the won — so the same corporate-action plumbing (the "July 29 conversion test," #41) that governs the ~22% sticky offshore premium is simultaneously a structural won bid. That coupling is why the won can firm through an equity crash AND why the offshore premium is sticky: the conversion channel is the shared valve. The counter-signal: it is a month-END dynamic (exporter selling, conversion timing), so both the won bid and the premium mechanics can fade into August — watch the turn.
- **Contested (carried):** the **memory valuation-vs-competition** de-rate is the driver, now with a US-session ADDITION — SK Hynix's +50% capex guide read as overheating (supply/valuation fear) on top of China self-sufficiency (CXMT + DUV). Demand stays locked ($950B LTAs); the Q2 margin was a record; Korea's own policy chief called it a valuation re-rating (12Z). *COI: the SK–Microsoft/Anthropic tranche and Kimi K3 vs Claude Fable 5 name Anthropic, this newsroom's related party — disclosed, on the merits, neither suppressed nor amplified.*
- **Changed since last (07-29 12Z pre-FOMC read-through → 18Z FOMC-reaction read-through):** (1) **the FOMC landed — a HAWKISH HOLD** (held 3.50–3.75%, but 9–3 with three dissents FOR a hike; inflation "elevated" on energy shocks) — the hawkish-hold risk realized; (2) **the US memory de-rate RE-INTENSIFIED** (SanDisk ~−7%, Micron ~−6%; the 12Z pre-market stabilization did NOT hold), on **SK Hynix's own +50% capex guide** read as overheating — a fresh supply/valuation trigger; (3) **the won read SHARPENED** — the strong-side decouple is driven by SK Hynix ADR-conversion dollar supply + month-end exporter selling + BOK-tightening bets (linking the two switches), possibly resisting the hawkish-hold dollar; (4) **oil confirmed BID** (Brent ~$87.3 / WTI ~$82.3 on US+Saudi/Iraq strikes; Scout canonical) — the energy shock the Fed named; (5) **Thursday's KRX inherits a doubly-negative handoff** (memory de-rate + hawkish hold) into a contested floor with no official put; (6) **verdict DEFERRED** — the won's FOMC reaction + the US memory close + Thursday's KRX are the tells, at/after cutoff.
