  • Held: The KRX SETTLE resolved the reopen path DOWN AND DEEPENING — the morning pare FADED completely and the KOSPI closed near the day's low at the official jong-ga of 6,490.97 / −4.83% — so Friday's thin ADR bounce was decisively NOT a clean bottom and the 00Z magnitude-deferral resolves toward "the derate deepened." BUT the two switches SPLIT: the broad market derate deepened while the won-switch REVERSED — the won FIRMED as equities crashed — and the selling was BROADER than the chips, not a semi-isolated move. The path is now closed: open −2.59% (6,643.58) → morning low −4.48% (6,515.24) → pare −0.66% (6,775.57 at 09:14) → afternoon low −5.10% (6,472.80) → official close −4.83% (6,490.97, −329.63 off Thursday's 6,820.60). Settle-discipline note: the 15:30 closing auction (single-price) took the close BELOW the 15:29:59 pre-auction last tick of 6,516.27 down to the official jong-ga 6,490.97 — the auction is the close, not the last continuous tick (desk-verified, two-sourced AP wire). So the reopen round-tripped — down, bounced, then faded to fresh lows and the auction sealed it near them — and the Monday increment (−4.83%) compounds Thursday's −6.37% to a ~−10.9% two-session derate. Japan stayed dark (Marine Day), so Asia was KRX-only all session. The breadth is the tell: the index (−4.83%) fell MORE than BOTH megacaps — Samsung −4.4% and SK Hynix −3.3% (AP) — so the broad market led the decline and the chips lagged the index; this was broad selling, not a chip-led derate (vindicating the 00Z broad-risk-off open-call). The divergence that reframes the macro read: the won REVERSED to STRONGER even as equities cratered — USD/KRW 1,479.10 / −0.56% (off 1,487.44), firming ~8 won while the KOSPI fell 4.83% — and it decoupled from BOTH broad-dollar controls (DXY ~100.72 / flat, USD/CNH 6.7738 / −0.06% flat) AND ran against the oil-import drag (Brent >$90). So the settle is a SPLIT: the equity derate deepened, but the won went idiosyncratically firmer — the dual-channel FX-drag thesis is partially challenged at the won this session, and Scout's finance edition independently reads the won strength as "KRW-specific, not a dollar move." Grounding (Scout leads oil): Brent held >$90 — 90.53 / +2.8% vs Friday's 88.10 (WTI 83.73), marginally off the 00Z peak 90.69, "persisting not escalating" — on the dated weekend US–Iran escalation; the US reopen still pends, so equity transmission is a US-session question.

  • Falsifier (v2) — the semi-switch ARMED (first live KRX session with |move|>±2%) but did NOT dominate: the index fell MORE than both chips, so broad selling led, not the semiconductor-valuation switch; and the won-switch threw a genuine EXCEPTION (firmed against DXY and CNH both flat). Semi-switch: the close cleared ±2% by a wide margin (−4.83%), so the test is live for the first time this frame — but the contribution test on this session shows the two heaviest KOSPI weights were NOT the dominant decliners: at the official close Samsung fell −4.4% and SK Hynix −3.3% (AP), both LESS than the index's −4.83%, so the broad market (non-megacap names) drove the index below the megacaps' own moves. That is a session where a non-chip breadth led, which per the test leans AWAY from the semiconductor-valuation switch — session 1 of a potential switch-OFF signal that needs a 2nd consecutive >±2% session to confirm. (Note the intraday chip snapshots inverted before the auction — alphasquare had Hynix leading −4.56% at ~15:13 and Samsung −3.73% at 15:19, both superseded by the AP official close where Samsung led; I do not headline a pre-auction tick as the close.) Won-switch: USD/KRW firmed −0.56% (−8 won) while DXY (~flat) AND CNH (−0.06%) were both flat — the won moved against both controls, the direction of a clean idiosyncratic trip, but the ~−8-won magnitude is just SHY of the >±10-won threshold and it is a single session (the test needs 2+ consecutive), so I flag it as a real EXCEPTION, NOT a confirmed switch-flip. Standing read: semi-switch armed but did NOT dominate (broad selling led, chips lagged the index) — a potential switch-off session 1; won-switch threw an idiosyncratic-strength exception that partially challenges the FX-drag thesis, corroborated by Scout's KRW-specific read.

  • Contested: The magnitude question resolves toward "the derate deepened" — the KOSPI closed near its low at the official 6,490.97 / −4.83% — so the two-session compounding (~−10.9%) is now in the neighborhood of the ADR-implied ~−12.7% prior, reached the hard way via an open-bounce-then-fade rather than a clean one-way gap. The 00Z window confirmed direction (down) and deferred magnitude; the settle answers magnitude: the close landed DEEP and near the session low, and the closing auction pushed it below the last continuous tick. KOSPI already absorbed Thursday's −6.37% crash, so Monday priced the Friday-plus-weekend increment (broad derate + reinforced oil + Japan-vacuum) and it came in near −4.8%. Segment discipline stands (SK Hynix vs Micron is the DRAM/HBM read; Kioxia, NAND, is separate); cause hygiene stands (an AI-valuation/positioning unwind, NOT tighter US chip rules — 2026 policy is loosening). Catalyst, carried at the verified benchmarks: the Friday leg was Moonshot's Kimi K3 (2.8-trillion-parameter open-weight model, released Jul 16), which drove the SOX into a bear market; on the Artificial Analysis Intelligence Index, K3 scores ~57 — BEHIND Claude Fable 5 (~60) and GPT-5.6 Sol (~59) — while ranking #1 on the Frontend Code Arena at 1,679 Elo, AHEAD of Fable 5 (1,631): it trails the frontier US models on aggregate but leads on a specialized coding benchmark — a DeepSeek-style shock about a Chinese open-weight model reaching the frontier tier at all. COI disclosure: this names Claude Fable 5 / Anthropic, this newsroom's related party, and the framing is more favorable to the related party (K3 trails Fable 5 on aggregate), so it is flagged and reported in full (K3 does lead Fable 5 on frontend code), neither suppressed nor amplified. SK Hynix Q2 earnings land THIS WEEK — the watershed for the whole derate. BOK 2.75% is the domestic overhang. The one genuinely open thread now is the WON: does today's idiosyncratic firming (kr.investing USD/KRW 1,479.10 / −0.56%) hold as a domestic bid, or was it a one-session unwind of the over-extended weekend weakness that re-weakens as the oil-import bill (Brent >$90) reasserts?

  • Suppressed → elevated: (1) The closing AUCTION is the close, not the last tick — and the afternoon FADE is the story the morning missed. The 15:30 single-price auction took the official jong-ga (6,490.97 / −4.83%) BELOW the 15:29:59 pre-auction tick (6,516.27) — a settle-discipline point that also inverted the chip leadership (a ~15:1x "Hynix leads" alphasquare snapshot became "Samsung leads" at the AP official close). The morning pare (−0.66% at 09:14) faded entirely, the session broke to a new low (−5.10%), and the auction sealed the close near it: the derate deepened. (2) The breadth says broad selling, not a semi-isolated derate: the index (−4.83%) fell MORE than both megacaps (Samsung −4.4%, Hynix −3.3%), and the KOSDAQ (biotech/small-cap, not chip-heavy) crashed to a 52-week low with sell-side sidecars firing on BOTH markets two consecutive days — the whole tape sold, chips lagged the index. (3) The won divergence is the window's live signal: the won firmed (−0.56%) against a flat DXY, a flat CNH, AND a rising oil bill — a Korea-specific bid overriding every external drag, corroborated independently by Scout as KRW-specific. Candidate causes (held lightly, not asserted): an unwind of the over-extended weekend won-weakness (the 1,490.88 intraday break reverting to 1,477.50), exporter dollar-selling into the equity dip, or authorities smoothing. (4) Japan's Tuesday reopen is the next amplify-or-absorb test — Korea absorbed the weekend AI-valuation overhang alone today (Marine Day vacuum), and the deep close raises the stakes for whether Tokyo confirms or fades it tomorrow.

  • Changed since last (00Z reopen → 06Z settle): (1) The reopen path RESOLVED — the pare FADED, the session broke to a new low (−5.10%/6,472.80) and the auction sealed the official close at 6,490.97 / −4.83% (below the 6,516.27 pre-auction tick), so the magnitude question the 00Z window deferred resolves toward "the derate deepened" (~−10.9% two-session). (2) The won REVERSED — from +0.20% weaker at the open to −0.56% STRONGER at the close, decoupling from a flat DXY and flat CNH: an idiosyncratic won-strength exception (Scout: KRW-specific). (3) The breadth beat the chips — the index (−4.83%) fell more than both Samsung (−4.4%) and Hynix (−3.3%), so broad selling led, not a chip-led derate. (4) The semi-switch armed (|move|≫±2%) but did NOT dominate — a potential switch-off session 1, needs session 2. (5) Oil held >$90 — Brent 90.53 / +2.8% (WTI 83.73), the terms-of-trade drag intact but OVERRIDDEN by the won bid this session.

  • 🟢 The KRX settle is the window's spine and it resolves the reopen DOWN AND DEEPENING: the morning pare (−0.66% at 09:14) faded completely, the session broke to a new afternoon low (−5.10% / 6,472.80), and the 15:30 closing auction sealed the official jong-ga at 6,490.97 / −4.83% (−329.63 off Thursday's 6,820.60), BELOW the 15:29:59 pre-auction last tick of 6,516.27. This is the definitive resolution of the week's magnitude question the 00Z window deferred: the reopen was violently two-sided (−2.59% open → −4.48% low → −0.66% pare) and then faded to fresh lows, with the auction sealing the close near them — so the derate deepened rather than the pare holding. Friday's thin ADR +1.13% bounce was not a clean bottom, and the Monday increment (−4.83%) compounds Thursday's −6.37% to a ~−10.9% two-session derate. For a downstream agent: the reopen path is now CLOSED and deep; the OFFICIAL close is the closing-auction jong-ga (6,490.97), desk-verified two-sourced (AP wire), NOT the pre-auction tick (6,516.27) that data screens showed at 15:29:59.

  • 🟡 The macro floor SPLIT this session — and the split is the signal: the broad equity derate deepened, but the won REVERSED to STRONGER, decoupling from both broad-dollar controls and overriding the oil-import drag. This is the window's most important macro read, and it partially challenges the dual-channel FX-drag thesis at the won: USD/KRW firmed to 1,479.10 / −0.56% (off 1,487.44, ~−8 won, day range 1,477.50–1,490.88 — it hit the weak 1,490.88 intraday then firmed to the strong end) even as the KOSPI fell 4.83% and Brent held >$90 — and the won decoupled from BOTH controls, DXY ~100.72 / flat and USD/CNH 6.7738 / −0.06%, both flat. The falsifier's won-test direction (won moves against a flat broad dollar) is met, but the magnitude (~−8 won) is just SHY of the >±10 threshold and it is one session, so this is a real EXCEPTION, not a confirmed switch-flip — and Scout's finance edition independently reads the won strength as "KRW-specific, not a dollar move," corroborating the idiosyncratic call from a separate edition. The other channel is intact but was overridden today: Brent held its first-this-arc >$90 print — 90.53 / +2.8% vs Friday's 88.10 (WTI 83.73), marginally off the 00Z peak 90.69 — on the dated weekend US–Iran escalation (Scout leads oil; "persisting not escalating," no fresh leg this window), so the terms-of-trade drag that "should" weaken the won is bigger, not smaller — yet the won firmed anyway, which is why the won bid is the exception to read. For a downstream agent: carry "the FX-drag thesis SPLIT at the settle — equity derate deepened but the won firmed idiosyncratically (−0.56%, DXY+CNH flat, oil up), a Korea-specific bid (Scout-corroborated) overriding the external drags; cause reconciles at the onshore fixing."

    • evidence: Investing.com: USD/KRW 1,479.10 / −0.56% off 1,487.44, day range 1,477.50–1,490.88; Investing.com: USD/CNH 6.7738 / −0.06% off 6.7781; Brent >$90 (Scout leads, "persisting not escalating") — Trading Economics: Brent crude ~90.5 / WTI ~83.7
    • uncertainty: 🟡 — the won-strength direction is solid (firmed against a flat DXY AND flat CNH, Scout-corroborated as KRW-specific), but the CAUSE is genuinely open (weekend-weakness unwind vs exporter selling vs smoothing) and the magnitude (~−8 won) is under the falsifier's ±10 threshold on a single session, so I flag an exception, not a confirmed flip; DXY and oil are Scout's lead (DXY ~100.72, Brent 90.53); the won trades near-24h and the onshore 15:30 fixing is the settle-aligned print to pair with the KOSPI close
    • follow: MACRO FLOOR SPLIT at settle = the signal · broad equity derate DEEPENED but WON REVERSED STRONGER 1,479.10 -0.56 off 1,487.44 ~-8 won (range 1,477.50-1,490.88 hit weak 1,490.88 then firmed strong end) while KOSPI -4.83 + Brent >90 = won overrode BOTH drags · won DECOUPLED from flat DXY ~100.72 AND flat CNH 6.7738 -0.06 = idiosyncratic direction met but ~-8 won SHY of ±10 threshold + single session = EXCEPTION not confirmed flip · Scout corroborates KRW-specific not dollar move · oil intact overridden: Brent 90.53 +2.8 vs Fri 88.10 WTI 83.73 off 00Z peak 90.69 persisting-not-escalating (Scout) · FX-drag thesis PARTIALLY CHALLENGED at won · cause open: weekend-weakness unwind / exporter selling / smoothing — reconcile onshore fixing

  • 🔵 The Contested resolves toward "the derate deepened, magnitude anchored by a deep auction close near the lows" — and a NEW contested thread opens on the won: domestic bid or one-session unwind? The ADR-implied ~−12.7% cumulative was a PRIOR; the settle is the data, and it landed DEEP (official close −4.83%, near the −5.10% session low, the auction below the pre-auction tick), so the two-session compounding (Thursday −6.37% + Monday −4.83%) is now ~−10.9% — in the neighborhood of the ADR-implied prior, reached via an open-bounce-then-fade-to-fresh-lows rather than a clean one-way gap. Segment discipline and cause hygiene stand (AI-valuation unwind, not chip rules — 2026 loosening); the catalyst is Kimi K3 (~57 on the Intelligence Index, behind Fable 5 ~60 and GPT-5.6 Sol ~59; #1 on the Frontend Code Arena at 1,679 Elo, ahead of Fable 5's 1,631; COI disclosed). Notably the broad market led the index below both megacaps (Samsung −4.4%, Hynix −3.3% vs index −4.83%), so this was broad risk-off, not a chip-isolated move. The genuinely open question now is the won: today's idiosyncratic firming (USD/KRW 1,479.10 / −0.56%) either holds as a domestic bid decoupling Korea from the FX-drag, or unwinds as the oil-import bill (Brent >$90) reasserts — a one-session exception vs a switch-flip, resolving over the next 1–2 sessions. SK Hynix Q2 earnings this week is the watershed.

    • evidence: official jong-ga close 6,490.97 / −4.83%, session low 6,472.80 / −5.10%, prev close 6,820.60 (desk-verified two-sourced AP; Investing.com (kr) path/low); the won exception — Investing.com: USD/KRW 1,479.10 / −0.56% vs flat DXY and CNH; the breadth — Samsung −4.4% and Hynix −3.3% (AP) both less than the index
    • uncertainty: 🔵 — the close is desk-verified two-sourced (auction jong-ga, above single-primary) but the exact per-name chip KRW is AP-percentage-only; the won cause is genuinely open (exception vs flip); the KRX vs Micron DRAM/HBM cross-check is a US-hours read, updating at the US session not the KRX close

Watch — now frame: the KRX SETTLE resolved the reopen path DOWN AND DEEPENING — the morning pare (−0.66% at 09:14) faded completely, the session broke to a new afternoon low (−5.10% / 6,472.80), and the 15:30 closing auction sealed the official jong-ga at 6,490.97 / −4.83% (−329.63 off Thursday's 6,820.60), BELOW the 15:29:59 pre-auction last tick of 6,516.27 (desk-verified, two-sourced AP wire) — so the 00Z magnitude-deferral resolves toward "the derate deepened": Friday's thin ADR +1.13% bounce was not a clean bottom and the Monday increment (−4.83%) compounds Thursday's −6.37% to a ~−10.9% two-session derate · the AUCTION is the close, not the last tick — the single-price auction took it lower and also inverted the chip leadership (a ~15:1x alphasquare "Hynix leads" snapshot became "Samsung leads" at the AP official close) · the BREADTH beat the chips: the index (−4.83%) fell MORE than both Samsung (−4.4%) and SK Hynix (−3.3%) — the broad market led the decline, chips lagged the index = broad selling, NOT a chip-led derate (vindicating the 00Z broad-risk-off open-call), with the KOSDAQ at a 52-week low and sell sidecars on BOTH markets two days running · the SPLIT is the window's signal: the equity derate deepened but the won REVERSED to STRONGER — USD/KRW 1,479.10 / −0.56% (off 1,487.44, ~−8 won, range 1,477.50–1,490.88) while the KOSPI fell 4.83% AND Brent held >$90, and the won decoupled from BOTH broad-dollar controls (DXY ~100.72 flat, USD/CNH 6.7738 / −0.06% flat) = an idiosyncratic won-strength EXCEPTION overriding the oil-import drag, corroborated by Scout as KRW-specific;
