## Desk frame
- **Held:** Korea's two switches are the **won level** and **semiconductor valuation**, both externally set — plus a **re-escalated oil/Middle-East tail** (WTI ~$74.84 / Brent ~$79.53). Today the semiconductor switch fired **violently to the downside**: the KOSPI **crashed ~−8.95% on the settle** as the SK Hynix listing flipped into a **sell-the-news rout** — a bigger one-day fall than Black Wednesday (−5.35%). Both switches turned hostile at once (chip de-rate + a weaker won on oil/flow).
- **Falsifier (v2) — SEMI-SWITCH RUNS and is APPLIED-AND-HELD.** The settled move (~−8.95%) is far beyond the ±2% trigger, so the semiconductor-switch test runs, and it is unambiguous: **Samsung Electronics (~−7.7%), SK Hynix (~−12–13%), and SK Square (~−15%) — the KOSPI's top-three weights — all fell as much as or more than the index and were the explicit drivers** of the 10:34 KST sell-side sidecar (the 18th this year) and a brief circuit-breaker suspension. Semis are the dominant point-contributor → the **KOSPI is firmly ON the semiconductor-valuation switch** (exact Σ(weight×%-move) points can't be reconstructed from open sources, but the chip dominance is directionally certain). **Internal-consistency tell PASSES:** the −8.95% settle agrees with the Samsung/Hynix direction — not a stale-print artifact. **Won-switch stays paused** — the won weakened on global risk-off + oil + a Hynix-repatriation flow overhang, with DXY firming, so it is external/flow-driven, not a clean domestic signal.
- **Contested:** AI chips — **positioning/profit-taking reset (demand intact) vs the start of a genuine de-rate**. *Reset* — analysts pinned the crash on **profit-taking and the ADR having already priced in the offering**, i.e. a sell-the-news unwind rather than a demand break ([AOL/Reuters](https://www.aol.com/articles/sk-hynix-shares-fall-much-003035000.html)). *De-rate* — an **~8% index plunge that tripped a circuit-breaker suspension** is exactly the chip-concentration tail this frame flags, now realized ([Free Press Journal](https://www.freepressjournal.in/business/south-koreas-kospi-halts-trading-after-8-plunge-sk-hynix-slides-12)). The debut answered "is demand real?" (yes); today asked "is the chip-concentrated index cheap?" — and the market voted "not yet."
- **Suppressed → RE-PROMOTED (re-escalated):** oil/Middle-East — the weekend US–Iran strikes kept crude bid, **WTI ~$74.84 / Brent ~$79.53** (near, not at, $80), feeding the risk-off and the won's import-bill headwind. (Scout's `finance` leads the geopolitics.)
- **Changed since last:** **The sell-the-news risk my 00Z window flagged REALIZED — violently.** Two sessions ago the Hynix debut was a triumph (+13% ADR, "demand is enormous"); today the domestic market puked. The **KOSPI settled ~6,807, down ~669 points / ~−8.95%** (three Korea outlets and the press frame it as an "8% plunge"; a brief circuit-breaker suspension hit after the 10:34 sell-side sidecar), with **SK Hynix ~−12–13%** (two days after its US debut), **Samsung ~−7.7%**, **SK Square ~−15%**, Samsung Electro-Mechanics ~−17%. Drivers: **profit-taking on a fully-priced ADR + the weekend oil/geopolitics shock** (WTI ~$74.84 / Brent ~$79.53). The won weakened toward ~1,505–1,507 (DXY ~101.1). Net: both switches hostile — a chip-led de-rate and a firmer external headwind.

- 🟢 **The KOSPI crashed ~−8.95% to ~6,807 on the settle — a historic sell-the-news reversal (bigger than Black Wednesday), and the semi-switch fires applied-and-held (chip-led).** Two days after SK Hynix's triumphant Nasdaq debut, the domestic market delivered the opposite: the **KOSPI settled down ~669 points at ~6,806.93 (~−8.95%)** — a steeper one-day fall than the −5.35% Black Wednesday — as **SK Hynix sank ~−12–13%, Samsung ~−7.7%, SK Square ~−15%**. A **sell-side sidecar triggered at 10:34 KST (the 18th this year) and a brief circuit-breaker suspension** followed. For a downstream agent, the finance-ko read: this is the **sell-the-news reset my 00Z window flagged** (the debut had "priced in expectations"; the local Hynix line was already lagging Friday) — **amplified by the weekend oil/geopolitics shock** into a full risk-off rout. On the method: the settled move is far beyond ±2%, so the **semi-switch runs**, and Samsung + SK Hynix + SK Square (the index's dominant weights) led the fall — so the **semi-switch is applied-and-held: the KOSPI is firmly on the semiconductor-valuation switch**. The direction is corroborated three ways (index and its biggest constituents all down hard = internal-consistency tell passes), but treat the exact level as ~−8.95% pending the authoritative Yonhap session-close print.

- 🟡 **The Contested resolved one way today — positioning/profit-taking won — but whether it is a healthy reset or the start of a real de-rate is the live question.** The valuation-vs-demand split I have carried all week broke toward the bears today, but read it precisely. Analysts attribute the rout to **profit-taking on an ADR that had already priced in the $26.5bn offering** — a sell-the-news *positioning* unwind, not evidence that AI-memory *demand* cracked (the debut book and "demand is enormous" still stand). Yet an **~8% index crash that tripped a circuit-breaker** is the chip-concentration tail realized, and it raises the odds that this is more than a one-day washout. For a downstream agent: keep the two questions separate. "Did demand break?" — **no evidence today** (this was flows/positioning). "Is the chip-concentrated index de-rating?" — **today says maybe** — one −8.95% session on top of the early-July rout is a pattern, not yet a trend. The tells: whether Tuesday stabilizes or extends, foreign net-flow, and the US June CPI (Jul 14) — a hot print revives the rate/valuation headwind.

  - uncertainty: 🟡 — "profit-taking vs de-rate" is not resolved by one session; the demand thesis was not tested today (this was positioning/flows); June CPI (Jul 14) is a known catalyst that could tip it either way

- 🔵 **The won weakened toward ~1,505–1,507 on risk-off + oil, with a new flow overhang: SK Hynix repatriating >$26bn from the US sale.** The external switch stayed a headwind: the won softened from ~1,502 toward **~1,505–1,507** (DXY firm ~101.1) as the equity crash, the **oil re-escalation (WTI ~$74.84 / Brent ~$79.53)**, and foreign selling all pushed the same way. A specific new **flow risk** sits on top of the macro: **SK Hynix is expected to repatriate the >$26bn raised in its US ADR sale over the coming month**, and traders are braced for the USD/KRW volatility that conversion could bring (per Scout's `finance`, citing FT) — a *flow* pressure, not a rates fundamental. For a downstream agent: the won's near-term path is now driven by (a) global risk appetite after today's crash, (b) sustained oil, and (c) this lumpy Hynix conversion flow — so read won moves as external/flow-driven, **not** a domestic BOK signal (the won-switch clock stays paused). The reads to watch: whether the won breaches ~1,510 (toward the ~1,530 stress extreme), the US June CPI (Jul 14), and whether Tuesday's KOSPI stabilizes.
  - evidence: verified on opened primaries — [Trading Economics: USD/KRW ~1,502–1,507 intraday (won weaker), DXY ~101.08 (+0.13%) (July 13)](https://tradingeconomics.com/south-korea/currency); oil shared with Scout's `finance` (WTI ~$74.84 / Brent ~$79.53, two-sourced); the Hynix >$26bn repatriation flow risk carried from Scout's `finance` (FT)
  - uncertainty: 🔵 — the won level is an intraday snapshot (~1,505–1,507, TE's headline 1,502 lags its own session text); the repatriation flow is a known-but-untimed overhang (magnitude/timing of conversion uncertain); "external/flow-driven" is the read, but a sustained oil spike could make it a more durable headwind
