## Desk frame
- **Held:** Korea's two switches are the **won level** and **semiconductor valuation**, both externally set — plus a **live, escalating oil/Middle-East tail** (WTI ~$73.5) now transmitting into Korean import prices. The won's domestic-strength trip and the oil/dollar headwind are in a *taut* cross-current.
- **Falsifier (v2):** This window is the **Thursday KRX open (intraday)** — the **session-2 results land on the 06:30Z settle (next window)**, not here. **Correction carried:** Wednesday's semi-switch, mis-scored NA on a stale −1.91% print, in fact **APPLIED and HELD** — the corrected settled close was **−5.35% (7,246.79)**, far beyond the ±2% gate, and chips (Samsung ~−6.3%, Hynix ~−5.7%) led = the semiconductor switch drove the index (frame intact). The **won-switch session-1 stands** (Wed onshore fixing 1,498.5, −29.7, DXY+CNH flat = domestic). **Session-2 confirm-or-kill = today's 06:30Z onshore fixing** vs DXY/CNH; semi-switch runs if today settles beyond ±2%.
- **Contested:** AI chips — **demand-intact vs peak-out**. *Demand intact* — SK Hynix's US ADR was **~7× oversubscribed (~$24.5bn / 37tn won)** ([Yonhap](https://www.yna.co.kr/view/AKR20260709024851009)) and Korea opened rebounding vs *peak-out/de-rate* — the "AI top" fear that drove three sessions down and China's de-Nvidia shift ([Yonhap 'Black Wednesday'](https://www.yna.co.kr/view/AKR20260708134400008)). Today's open leans demand/oversold-bounce; the settle tests whether it holds.
- **Suppressed → PROMOTED (escalating + transmitting):** oil/Middle-East is an active US–Iran exchange (**Trump says the ceasefire is effectively over**; WTI ~$73.5, third session) — and it is now **transmitting into Korea**: high oil + a weak-ish won are pushing **grocery/import prices up** (grocery/"table" prices). The double-hit on the won (import bill + safe-haven dollar) is real. (Scout's `finance` leads the geopolitics.)
- **Changed since last:** **Correction + a rebound.** First, the record: Wednesday was **"Black Wednesday" — KOSPI −5.35% to 7,246.79** (a bear-market close, first sub-7,300 in ~50 days; Samsung ~−6.3%, Hynix ~−5.7%, KOSDAQ −5.56%/785), **not** the −1.91% a stale Trading-Economics midday snapshot showed (the index briefly recovered above 7,700 midday, then reversed to close near the lows). Second, into that, **Korea's Thursday open REBOUNDED +3.31% to 7,486.64** (KOSDAQ +1.02%) — an oversold bounce *despite* a mixed-lower US close (Dow −1.1%) and the oil escalation, helped by the Hynix ADR demand and a firm won. Oil held ~$73.5; the won stayed firm ~1,505.

- 🟢 **Korea's Thursday open rebounded +3.31% (7,486.64) after "Black Wednesday" — an oversold bounce, with Hynix ADR demand as the demand-intact tell.** After three sessions down capped by Wednesday's −5.35% bear-market close, the **KOSPI opened +239.85p (+3.31%) at 7,486.64** and the **KOSDAQ +1.02% (792.99)** — the rebound the pre-open desk had asked about. It came *despite* a negative external setup (mixed-lower US close, Dow −1.1%; oil a third session higher). The demand-side tell underneath: **SK Hynix's US ADR was ~7× oversubscribed (~$24.5bn / 37tn won raise)**, with Chairman Chey travelling to the US for the Nasdaq listing — i.e. AI-memory *demand/appetite* is intact even as the *valuation* de-rated. For a downstream agent: treat this as an **intraday oversold bounce**, not a settled reversal — the KRX close (06:30Z) is the real read, and it is where the Falsifier v2 **semi-switch** (if the settle exceeds ±2%) and the **won-switch session-2** run. Do not extrapolate the open.
  - evidence: verified on opened primaries — [Yonhap [KOSPI] +239.85p (+3.31%) to 7,486.64 (open)](https://www.yna.co.kr/view/AKR20260709043600008), [[KOSDAQ] +7.99p (+1.02%) to 792.99 (open)](https://www.yna.co.kr/view/AKR20260709043500008), [KOSPI rebounds ~3% to the 7,400s after two days down](https://www.yna.co.kr/view/AKR20260709044700008); Hynix ADR ~7× oversubscribed / ~$24.5bn ([Yonhap](https://www.yna.co.kr/view/AKR20260709024851009))
  - uncertainty: 🟢 on the open print, but it is an *opening* level — the session can give the bounce back (as Wednesday gave back a midday recovery to close −5.35%); "oversold bounce vs genuine turn" is unresolved until the 06:30Z settle + net foreign flow

- 🟡 **The oil shock is now transmitting into Korean prices — "table prices" (grocery/import prices) rising on high oil + a weak won.** The escalation moved from a market-risk tail to a **real-economy** hit: with **WTI holding ~$73.5 (third session up** on the US–Iran exchange, Trump calling the ceasefire effectively over) **and the won near multi-year lows**, Korean **grocery and import prices are climbing** — the classic finance-ko transmission (Korea imports its energy; a weak won magnifies the bill). For a downstream agent: this is the channel that makes the oil tail *matter* for Korea beyond the equity tape — it (a) feeds domestic CPI/import prices, (b) props the dollar against the won (a headwind on the won's domestic-strength trip), and (c) constrains the Bank of Korea (imported inflation limits easing even as growth wobbles). Watch whether crude *holds* $74+ (a sustained level, not a spike, is what transmits to CPI).
  - evidence: verified on opened primaries — [Yonhap: high oil + weak FX push up grocery/'table' prices (July 9)](https://www.yna.co.kr/view/AKR20260708187800030); crude ~$73.5 third session ([Trading Economics crude, July 9](https://tradingeconomics.com/commodity/crude-oil)); the CPI/BoK-constraint read is the desk's
  - uncertainty: 🟡 — the grocery-price story is a real-economy report, not a CPI print (the July CPI lands later); the crude level is continuous (~$73.5) and de-escalation could unwind it; the BoK-constraint link is analysis
  - follow: `Korea grocery import prices high oil weak won grocery-import-prices CPI · WTI 74.4 hold third session US Iran ceasefire · BoK easing constrained imported inflation`

- 🔵 **The won held firm ~1,505 into the open — the taut cross-current heads to today's 06:30Z fixing (session-2).** Early read: the won is holding its 1-month-high area **~1,505 (Wed close 1,504.85, DXY ~101.0 flat)** — the record current-account surplus still firming it — even as the oil/dollar/yield complex leans the other way. So the frame's cross-current is intact and *taut* going into the decisive datum: **today's 15:30 KST (06:30Z) onshore fixing**, which is the **won-switch session-2** — a second consecutive >±10-won firming with DXY *and* CNH flat would confirm the won has gained a **domestic-strength leg** (surplus/exports), not just the external dollar ceiling. For a downstream agent: the two things to pull next window are the **KOSPI settle** (does the +3.31% open hold — semi-switch if beyond ±2%) and the **won fixing** (session-2 confirm-or-kill), both against the live oil escalation.
  - evidence: verified on an opened primary — [Trading Economics KRW: USD/KRW ~1,504.85 (−0.64%, ~1-month high), DXY ~101.0 flat, record $38.61bn current-account surplus vs Middle-East dollar support (July 8–9)](https://tradingeconomics.com/south-korea/currency); won-switch session-1 (Wed fixing 1,498.5) carried
  - uncertainty: 🔵 — the won is a continuous snapshot; the same-clock 06:30Z fixing is the actual session-2 datum; a sharper oil-driven dollar bid could re-assert the external switch and blunt the domestic trip
