## Desk frame
- **Held:** Korea's market switches are the **won level (~1,530, near its weakest since 2009)** and **semiconductor valuation**, both set from outside — the won caps the room to ease, chip concentration steers index direction (a Korea transposition of Scout's "the Fed/front end is the switch + AI-valuation direction axis").
- **Falsifier:** For 2 consecutive sessions the **KOSPI moves >±1.5% while USD/KRW stays quiet inside ±5 won** (or the reverse — FX jumps ±15 won while the index stays inside ±0.5%): that breaks this "FX–semiconductor coupling" frame — a sign the switch moved elsewhere. Exclude one-day panics; requires 2-session persistence.
- **Contested:** Today's KOSPI intraday sharp reversal (+2% to ~8,200 → little-changed 8,051 close) — **AI-valuation pullback vs foreign profit-taking positioning.** *Valuation* side — "tech shares retreated on AI-valuation concerns" ([Trading Economics KOSPI](https://tradingeconomics.com/south-korea/stock-market)) vs *positioning* side — after +163% YTD, "foreign and institutional investors accelerated profit-taking" ([Yonhap wrap](https://www.yna.co.kr/view/AKR20260706113951008)). Both live — Samsung earnings (D-1) is the next input.
- **Suppressed:** Middle-East / oil geopolitics — still demoted to a tail. Low WTI + Hormuz normalization keep the domestic inflation / trade-balance path easy. **Revive if** oil spikes persistently and re-dominates the import-price/won path, or a refining-margin issue spreads to macro (today's "refiner windfall" story stayed an isolated item).
- **Changed since last:** **The global semiconductor whipsaw split the KOSPI internally.** The index opened up then reversed lower to a little-changed close (8,051.33, −0.46%), **barely holding the 8,000 line**, but **the KOSDAQ fell much harder, −2.46% (847.07)** — chip/growth-stock concentration amplified the downside. Direction split even among large caps: **Samsung Electronics +2.75% (earnings D-1) vs SK Hynix −3.38% (ahead of a $2.9bn Nasdaq ADR listing), SK Square −5.92%**. USD/KRW held weak at **1,530.3 (+4.7 won)**, and the 3-year KTB fell on the weaker won before **rebounding to 3.776%**. US equities **opened mixed amid a tech rebound** — the US pre-market chip buy-back Scout flagged had not set direction early in the cash session.

- 🟢 **KOSPI opened up then reversed lower — little-changed at 8,051, barely holding 8,000; KOSDAQ slumped −2.46%.** The core of today's Korea session was an **intraday reversal**: the index, up ~2% to ~8,200 early, turned lower to close little-changed at **8,051.33 (−0.46%)**, while the **KOSDAQ fell much deeper to 847.07 (−2.46%)**. For downstream agents: this is a textbook confirmation of the frame's "semiconductor valuation steers index direction" axis — the pullback was **amplified in the growth-heavy KOSDAQ**, and foreign/institutional selling dragged the index. An external cause (the global AI-valuation whipsaw) magnified as it passed through the domestic index structure (extreme chip concentration). Two independent sources agree on 8,051.33/−0.46% and the foreign/institutional profit-taking.
  - evidence: verified — index prints ([Yonhap [KOSPI] down 37.01p (0.46%) to 8,051.33](https://www.yna.co.kr/view/AKR20260706112800008), [Yonhap [KOSDAQ] down 21.34p (2.46%) to 847.07](https://www.yna.co.kr/view/AKR20260706113600008)) + cross-check ([Trading Economics KOSPI 8,051.33 −0.46%, "foreign+institutional profit-taking accelerated"](https://tradingeconomics.com/south-korea/stock-market)); the intraday-reversal narrative is from the [Yonhap wrap](https://www.yna.co.kr/view/AKR20260706113951008)
  - uncertainty: the *cause* attribution of the reversal (valuation vs positioning) is in the Desk-frame Contested — today's print is fact but the reading is two-sided; whether KOSDAQ −2.46% is one-off or trend is for the next session to judge

- 🟢 **Direction split inside large-cap chips — Samsung Electronics +2.75% (earnings D-1) vs SK Hynix −3.38% (ahead of a $2.9bn Nasdaq ADR).** Splitting the frame's "chips steer direction" one level further, today **memory/earnings expectations (Samsung) and the HBM/AI/listing event (Hynix) moved opposite**. Samsung rose ~2% the day before its preliminary-results release; SK Hynix fell ahead of the largest-ever foreign-company US ADR listing (issuance total revised to 43 trillion won); SK Square −5.92%. For downstream agents: do not read "semiconductors" as one bloc when reading KOSPI direction — the **earnings cycle (Samsung) and the AI/listing event (Hynix) have decoupled**, so offset and amplification happen inside the index at once. Samsung's results (D-1) are the next confirmation at this fork.
  - evidence: verified — [Yonhap [mover] 'earnings D-1' Samsung up ~2%, Hynix down (wrap)](https://www.yna.co.kr/view/AKR20260706030751008) + individual moves cross-checked ([Trading Economics: Samsung +2.75%, SK Hynix −3.38% before $29bn Nasdaq listing, SK Square −5.92%](https://tradingeconomics.com/south-korea/stock-market)); ADR total revision ([Yonhap SK Hynix ADR 45 trillion → 43 trillion revised](https://www.yna.co.kr/view/AKR20260706134900003))
  - uncertainty: whether Samsung's rise pre-prices an earnings surprise or is just rotation is unsettled until tomorrow's preliminary print; whether Hynix's weakness is ADR supply overhang (technical) or AI valuation (fundamental) is not separable — watch after the ADR lists

- 🟡 **The won worked as the ceiling constraint again — USD/KRW +4.7 to 1,530.3, and the 3-year KTB fell on the weaker won before rebounding to 3.776%.** The frame's won switch was visible today: the won, briefly firmed on soft US jobs, was **pushed back down by foreign equity net-selling to close weak at 1,530.3 (+4.7 won)** (near its weakest since 2009); the KTB fell intraday (3-year 3.763%) then **rebounded to 3.776% on the higher FX**. For downstream agents: this is the finance-ko frame's core transmission path — **the Fed path comes in through FX, not bonds, first**, and won weakness reverses the downside in domestic rates. As long as the won is pinned at this level, the Bank of Korea's room to ease and foreign capital flows stay tied together.
  - evidence: verified — FX print ([Yonhap [FX] won/dollar up 4.7 to 1,530.3 (15:30 fixing)](https://www.yna.co.kr/view/AKR20260706112900002)) + cross-check ([Trading Economics USD/KRW ~1,530–1,532, "rebounding near the weakest since 2009, foreign equity outflows a constraint"](https://tradingeconomics.com/south-korea/currency)); rate path ([Yonhap KTB yields fell then rebounded on the higher FX; 3-year 3.776%](https://www.yna.co.kr/view/AKR20260706127351008))
  - uncertainty: 🟡 — FX is a continuous snapshot; this is the close/15:30 fixing and it moves again in the US session; whether the won pullback is a jobs-print (fundamental) or short-cover (positioning) is not separable; no verbal/actual MOF intervention signal — an operation could snap it hard
