## Desk frame
- **Held:** Korea's two switches are the **won level** and **semiconductor valuation**, both externally set — plus an **oil/Middle-East tail that paused** (WTI ~$73.5). After a violent week (Black Wednesday −5.35%, Thursday's whipsaw close +0.62%), the global AI de-rate is **stabilizing** into Korea's Friday.
- **Falsifier (v2) — Thursday resolved, cross-checks closed:** No new Korea session this window. **Won-switch session-2 = NOT confirmed, now validated on the authoritative same-clock fixing** — the Thursday 15:30 onshore fixing printed **+7.6 won *weaker* to 1,506.1** (vs Wed's 1,498.5), so the domestic-firming did not extend (the TE snapshot read was right). The won stays primarily the **external dollar ceiling**. **Semi-switch = NA** stands (settled +0.62% inside ±2%). **Data-integrity close-out:** the Yonhap session-close for Thursday cleared the RSS lag at **+0.62% / 7,291.91** — authoritative; our 06Z publish used Yahoo's ~+0.26% / 7,265.63 (its ~2-min-post-close daily bar was ~26 pts low), so the **published 06Z KOSPI close is being corrected up (desk-approved)** to 7,291.91 (TE's +0.54% was actually closer this time — a note for the source hierarchy).
- **Contested:** AI chips — **de-rate stabilizing vs still-a-top**. *Stabilizing* — **Nvidia +3.65% recovering** after shedding ~$1tn, with memory (Micron/SanDisk) +3% premarket ([Trading Economics US](https://tradingeconomics.com/united-states/stock-market)) vs *still-a-top* — the AI-peak-out fear and China's de-Nvidia shift that drove the week's rout ([Yonhap 'Black Wednesday'](https://www.yna.co.kr/view/AKR20260708134400008)). Today the de-rate paused; whether it is a bottom or a pause is Friday's question.
- **Suppressed → PROMOTED (paused):** oil/Middle-East is still live but **cooled** — **WTI held ~$73.5–74 (paused, not resuming steep gains)** even as the US–Iran exchange keeps the Strait of Hormuz in focus; vessel tracking shows **Hormuz transits declined but actual disruption is uncertain**. So the won's oil-import/dollar-support headwind eased at the margin today. (Scout's `finance` leads the geopolitics.)
- **Changed since last:** **The rout paused — globally and in the read-through to Korea.** The US AI complex **stabilized**: **Nvidia +3.65%** clawing back after its ~$1tn drop, **memory names +3%**, **Nasdaq-100 +0.27%** (S&P −0.28%) — a calmer tape than the three-session bleed. Oil **paused ~$73.5** (Hormuz disruption still unproven). On the record: Thursday's KOSPI **authoritatively closed +0.62% at 7,291.91** (Yonhap session-close, correcting the ~+0.26% Yahoo intraday we published), and the **won fixing came 1,506.1 (+7.6 weaker)** — confirming the won-switch did not extend. KTB 3y eased its rise to ~3.778% (Trump/Shin remarks). Net: Korea heads into Friday with a **less hostile external setup**.

- 🟢 **The AI de-rate stabilized — Nvidia +3.65% clawing back after its ~$1tn drop, memory +3% — a calmer read-through into Korea's Friday.** After the week's rout (Black Wednesday, then Thursday's +3.31%→−2%→+0.62% whipsaw), the global AI trade steadied in the US session: **Nvidia recovered ~+3.65%**, **Micron and SanDisk were ~+3% premarket**, and the **Nasdaq-100 turned up +0.27%** (S&P 500 −0.28%, Dow-heavy weakness) as investors "reconsidered AI infrastructure outlooks." For a downstream agent, the Korea read is a **less hostile setup for Friday**: the negative chip lead that dragged three Korean sessions has, for now, flipped to a stabilizing/recovering one — supportive of Korea's memory names (Samsung/SK Hynix) at the Friday open. Keep it measured: this is an **intraday US read** (not the settled close), and a one-session bounce after a $1tn drawdown is a *pause*, not a confirmed bottom — the AI-peak-out and China-de-Nvidia threads are unresolved.
  - evidence: verified on an opened primary — [Trading Economics US (July 9, intraday): S&P 500 7,494.84 (−0.28%), Nasdaq-100 29,404.83 (+0.27%), Nvidia +3.65%, Micron/SanDisk ~+3% premarket, Meta −2%](https://tradingeconomics.com/united-states/stock-market); the ~$1tn Nvidia drop carried from the 06Z window
  - uncertainty: 🟢 on the stabilization direction but the levels are **intraday** (US close ~20:00Z could fade); "pause vs bottom" is unresolved; Meta −2% on its own chipmaking plans is a reminder the hyperscaler-capex debate is still live

- 🟡 **Cross-check closed + won-switch validated: Thursday KOSPI authoritatively +0.62% / 7,291.91, and the won fixing (1,506.1, weaker) confirms session-2 did not extend.** Two data-integrity items resolved this window. (1) The **Yonhap session-close** for Thursday cleared the RSS lag: **KOSPI +0.62% / 7,291.91** (KOSDAQ +1.15% / 794.00) — the authoritative print. Our 06Z publish used Yahoo's post-settle bar (~+0.26% / 7,265.63), which was **~26 pts low** (it read ~2 min after the close, still incomplete); TE's +0.54% was closer. Same direction (a modest gain, inside ±2% so **semi-switch NA is unchanged**), but the **published figure is being corrected up to 7,291.91**. (2) The **won-switch session-2** now checks out on the authoritative same-clock number: the **15:30 onshore fixing was 1,506.1, +7.6 won *weaker*** than Wed's 1,498.5 — i.e. the domestic-firming did **not** extend, so the **NOT-confirmed verdict holds** on the real fixing, not just the TE snapshot. For a downstream agent: the won remains the **external dollar ceiling**; Wednesday's firming was a one-session surplus reaction.
  - evidence: verified on the authoritative primaries — [Yonhap [KOSPI] +45.12p (+0.62%) 7,291.91 (session close, July 9)](https://www.yna.co.kr/view/AKR20260709150900008); [Yonhap [FX] won/dollar +7.6 to 1,506.1 (15:30 fixing, July 9)](https://www.yna.co.kr/view/AKR20260709149600002); the ~+0.26% Yahoo / +0.54% TE reads carried from the 06Z reconciliation
  - uncertainty: minimal on the numbers now (authoritative Yonhap prints); the only open item is the desk applying the +0.62%/7,291.91 correction to the published 06Z on both editions (desk-approved)

- 🔵 **Oil paused ~$73.5 and KTB yields eased their rise — the external pressure on the won cooled at the margin into Friday.** The two external headwinds on the won both softened today. **Oil paused: WTI held ~$73.5–74 (+0.6%)** rather than resuming its climb — the US–Iran exchange keeps Hormuz in focus, but **vessel tracking shows transits declined without confirmed disruption**, so the supply-scare premium stalled. And **KTB 3y eased its rise to ~3.778%** after Trump and BIS's Shin Hyun-song remarks. For a downstream agent, the finance-ko read is that the won's **import-bill + dollar-support + yield legs all cooled a notch** — consistent with the won's fixing giving back only modestly (1,506.1). Watch for whether crude stays paused (a *sustained* $70s level still transmits to Korean CPI/import prices over time) and whether Friday's Korea open converts the stabilizing global tape into a genuine recovery or just another failed bounce.
  - evidence: verified on opened primaries — [Trading Economics crude: WTI ~$73.97 (+0.61%), held near $73.5, Hormuz transits declined but disruption uncertain (July 9)](https://tradingeconomics.com/commodity/crude-oil); KTB 3y ~3.778% ([Yonhap: KTB yield rise moderated on Trump/Shin remarks (July 9)](https://www.yna.co.kr/view/AKR20260709175200008))
  - uncertainty: 🔵 — crude is a continuous snapshot (~$73.5, paused not reversed); the Hormuz disruption is unconfirmed (tracking-limited); the "external pressure cooled" read is a one-session margin, not a trend
