## Desk frame
- **Held:** Korea's two switches are the **won level (~1,515–1,522, near 2009 lows)** and **semiconductor valuation**, both externally set — now with a **re-emerged third external force: oil/Middle-East geopolitics** (see Changed-since). The won caps easing/flows; chip concentration sets index direction; oil newly pressures the won/import-price path.
- **Falsifier (v2 — first window on the new test):** Two switch-specific tests on *same-clock* snapshots (KOSPI onshore 15:30 close vs the won's onshore 15:30 fixing). **Won-switch test: NOT tripped** — the won is ~1,521.64 (weaker on the day) while the **DXY firmed +0.33% to 101.19**, so the won is tracking the external dollar, not domestic forces (a clean-domestic trip needs >±10 won with DXY *and* CNH flat). **Semi-switch test: pending the settled close** — today's KOSPI move exceeds ±2% (opened −2.66%), so the test *applies*, but per the same-clock rule it runs on the **06:30Z settled close** with per-name contributions (Samsung/SK Hynix/SK Square vs total net points); the opening print is chip-led (frame provisionally holds), with **broadening foreign selling into autos (Hyundai) a watch-item** for whether semis stay the dominant driver.
- **Desk note — Falsifier v2 (2026-07-08):** the prior falsifier ("KOSPI moves >±1.5% while USD/KRW stays within ±5 won") is **retired**. It was flawed two ways: (a) *snapshot-dependent* — under 24h FX it depended on whether you matched the equity close to the onshore 15:30 fixing (won −2.1, quiet) or a later 24h print (won −15); (b) it tested the *thesis* (two independent switches) rather than its refutation — it would fire exactly when the frame is TRUE. **v2** instead tests each switch's *driver* directly (chips dominant in the index point-move; the won tracking the broad dollar), on contemporaneous same-clock snapshots, over 2+ consecutive sessions.
- **Contested:** The AI-inflation axis just gained a second front. On **AI**, is the chip de-rate valuation or demand — Intel −9.7% / AMD −6.5% / Micron −4.7% ([Trading Economics US](https://tradingeconomics.com/united-states/stock-market)) vs demand-intact signals — **Nvidia +0.7%** and SK Hynix's US ADR **oversubscribed several times** ([Yonhap](https://www.yna.co.kr/view/AKR20260708015800009)). On **oil**, the disinflation anchor is **flipping toward inflationary** — a Strait-of-Hormuz supply scare ([Bloomberg: US revokes Iran oil waiver](https://www.bloomberg.com/news/articles/2026-07-07/us-revokes-waiver-allowing-iran-oil-sales-after-tanker-attacks)). For Korea both fronts pressure the same variable: the won.
- **Suppressed → PROMOTED:** Middle-East / oil geopolitics is **no longer suppressed** — the revive-if fired on **both** legs (ceasefire break / strikes resume **and** a sustained crude spike from shipping disruption). It is now a live Changed-since item.
- **Changed since last:** **A geopolitical oil shock landed on top of the chip de-rate — the disinflation anchor that held all cycle is reversing.** Overnight the **US carried out fresh air strikes on Iran and revoked the Iran oil-sales waiver** after **Strait-of-Hormuz tanker attacks** (a Qatari LNG carrier and a Saudi crude tanker struck); **WTI spiked ~+5.8% to ~$72.5** (from ~$68.5). Simultaneously the **US closed lower** (Nasdaq −1.8%, S&P −0.71% (7,483.76); Intel −9.7%, AMD −6.5%, Micron −4.7%, though Nvidia +0.7%) on the AI-capex-skepticism chip de-rate, and **Korea opened down again −2.66% (7,452.48, intraday), session 2** of the decline. The **won weakened back to ~1,521.64 as the DXY firmed (+0.33%)**. So Korea now faces **three external forces stacked**: the chip-valuation de-rate, a firming dollar, and — newly — an inflationary oil/geopolitics supply scare, all bearing on the won and the index.

- 🟢 **A Middle-East oil shock is the day's new frame driver — US strikes on Iran + a revoked oil waiver + Hormuz tanker attacks spiked WTI ~+5.8% to ~$72.5.** Overnight the geopolitics tail this desk had kept *suppressed* fired hard and on both revive-if legs: the **US launched fresh air strikes on Iran** (CENTCOM, after attacks on three commercial vessels in the Strait of Hormuz — a Qatari LNG carrier and a Saudi crude tanker among them) **and revoked the sanctions waiver that let Iran sell oil**, reversing a June interim-deal element. **WTI jumped ~+5.8% to ~$72.5** (from ~$68.5). For a downstream agent, the Korea read is specific and stacked: Korea is a major energy importer with an already-weak won, so an inflationary crude spike (a) **pressures the won and import prices** directly, (b) **flips the oil side of the AI-inflation debate toward inflationary** — reversing the disinflation anchor that had supported the dovish Fed path all cycle, and (c) stacks a **geopolitical risk-off** on top of the semiconductor de-rate. Caveat: some headlines float an escalation toward **$80** — that level is **unverified**; the confirmed print is ~$72.5 / +5.8%.
  - evidence: verified on opened primaries — [Trading Economics crude: WTI ~$72.5 (+5.8%), Strait-of-Hormuz tanker attacks, supply-disruption fears (July 8)](https://tradingeconomics.com/commodity/crude-oil); [Bloomberg: US revokes waiver allowing Iran oil sales after tanker attacks (July 7)](https://www.bloomberg.com/news/articles/2026-07-07/us-revokes-waiver-allowing-iran-oil-sales-after-tanker-attacks); [Al Jazeera: US says strikes launched, explosions in southern Iran (July 7)](https://www.aljazeera.com/news/2026/7/7/us-says-strikes-launched-as-explosions-heard-in-southern-iran)
  - uncertainty: the crude level moves continuously (~$72.5 is the verified current, not a settled close); the "$80" escalation level is unverified and excluded; the *durability* of the spike depends on whether Hormuz shipping is actually disrupted vs a headline risk premium; second-order won/CPI impact is a forward read, not yet in the data

- 🟢 **Korea opens down again −2.66% (session 2) as the US chip de-rate deepened into its close — now compounded by the oil shock.** The negative global chip lead carried straight into Korea's Wednesday open: the **KOSPI opened −2.66% at 7,452.48** and the **KOSDAQ −1.79% at 816.39** (both intraday opening prints — KRX settles at 06:30Z), extending Tuesday's −4.91% into a **second session** of the decline. This followed the **US settled close lower — Nasdaq 100 −1.8%, S&P 500 −0.71% (7,483.76)** — with the chip complex broadly weak (**Intel −9.7%, AMD −6.5%, Micron −4.7%**) though **Nvidia rose +0.7%**, i.e., an AI-capex-skepticism de-rate that is broad but not uniform. For a downstream agent: hold this as *intraday, session-2* — the settled close (06:30Z) is where the Falsifier v2 semi-switch test runs (are Samsung/SK Hynix/SK Square still the dominant contributors, or is the selling broadening — note the flagged **unusual foreign outflow from Hyundai**). The dip-buy that rescued Monday has not reappeared; the oil shock now adds a risk-off leg the chip de-rate did not have.
  - evidence: verified on opened primaries — [Yonhap [KOSPI] −203.83p (−2.66%) to 7,452.48 (open)](https://www.yna.co.kr/view/AKR20260708038800008), [[KOSDAQ] −14.84p (−1.79%) to 816.39 (open)](https://www.yna.co.kr/view/AKR20260708038700008); US settled close + per-name chips ([Trading Economics US: Nasdaq −1.8%, Intel −9.7% / AMD −6.5% / Micron −4.7% / Nvidia +0.7%, July 7](https://tradingeconomics.com/united-states/stock-market)); Hyundai foreign-outflow flag ([Yonhap](https://www.yna.co.kr/view/AKR20260708030100008))
  - uncertainty: the KOSPI/KOSDAQ figures are *opening* prints, not the settle (06:30Z) — the session could pare or deepen; whether the decline stays chip-led or broadens (Hyundai) is exactly what the settled semi-switch test resolves next window

- 🔵 **The won weakened back to ~1,521.64 as the dollar firmed — the won-switch test confirms it is on the external dollar, not domestic forces.** Applying Falsifier v2's won-switch test cleanly: the **won is ~1,521.64 (−0.47% on the day, weaker)** while the **DXY firmed +0.33% to 101.19** — so the won's move is *dollar-driven*, the external switch working as the frame says, **not** a domestic/idiosyncratic trip (which would need >±10 won with DXY *and* CNH both flat). For a downstream agent: this matters because the won is now being pushed by *two* external forces pointing the same way — a firming dollar **and** the oil-import bill from the crude spike — against the backdrop of continued foreign equity outflows. The BoK's room to ease stays pinned. The next reads: the **KOSPI 06:30Z settle** (the semi-switch test), whether **crude holds ~$72+** (won/CPI transmission), and **FOMC minutes** later today.
  - evidence: verified on opened primaries — [Trading Economics KRW: USD/KRW ~1,521.64 (−0.47%), DXY 101.19 (+0.33%), won move dollar-driven amid persistent foreign outflows (July 8)](https://tradingeconomics.com/south-korea/currency); crude spike from item 1; foreign-outflow context carried
  - uncertainty: 🔵 — FX is a continuous 24h snapshot; the won-switch test is a same-day read (needs 2+ consecutive sessions to *trip*, and it is not tripping — it is confirming the external-switch frame); a sharp further crude spike could add a distinct oil-driven won leg worth separating out
