## Desk frame
- **Held:** Korea's two switches are the **won level** and **semiconductor valuation**, both externally set — plus an **oil tail reasserting at ~$79 WTI / ~$85 Brent** (Trump dropped the proposed Hormuz fee, but crude is climbing back into Asia). Korea **reopens Wednesday into a chip-supportive-but-cooling setup**: the dovish-CPI relief held into the US close (chip-led) and SK Hynix is shipping HBM4 — but the **SK Hynix ADR settled +11% ($169.18), well off its +23% intraday peak**, so the US momentum cooled into the close. The won firmed further (~1,487.68). A follow-through bounce is the base case after Tuesday's fragile +0.73%, but capped.
- **Falsifier (v2) — do NOT run on the open.** This is the **Wednesday KRX open (directional only)**; the **semi-switch runs on the 06:30Z settle (next window)** if the KOSPI net move exceeds ±2%. It was **NA on Tuesday's +0.73%** (inside ±2%). **Won-switch stays paused, but watch an emerging domestic angle:** the won firmed to ~1,487.68 (highest since mid-May) on the soft dollar + Hynix flow **plus growing BOK rate-hike expectations** — the last is the first potential *domestic* driver in weeks, though it is still an expectation, not policy, so the clock stays paused.
- **Contested:** AI chips — **demand validated (HBM4, chips closed up Tuesday) vs the US momentum cooling and the ADR premium normalizing.** *Demand* — SK Hynix is in **mass production of 12-layer HBM4 for Nvidia**, and Samsung/SK Hynix **closed up Tuesday (+3.34%/+3.69%)** ([Seoul Economic Daily](https://en.sedaily.com/finance/2026/07/14/kospi-swings-but-holds-6800-samsung-sk-hynix-close-up-3)). *Cooling* — the **SK Hynix ADR settled only +11% at $169.18** (giving back most of its +23% intraday spike), so the earlier ~46–50% ADR premium is **normalizing off the peak** ([Investing.com SKHY](https://www.investing.com/equities/sk-hynix-adr)) — exactly the "dislocation unwinds by the ADR falling toward the local" path flagged last window. Demand is intact; the momentum is cooling.
- **Suppressed → elevated (crude reasserting):** oil/Middle-East — **WTI ~$79 / Brent ~$85** (two-sourced with Scout's `finance`); even though **Trump dropped the proposed Hormuz cargo fee**, crude is **reasserting back to ~$85 Brent into Asia** as the Iran–Hormuz risk lingers — a live won-import/July-CPI headwind that keeps the July tail alive. (Scout's `finance` leads the geopolitics and crude figure.)
- **Changed since last:** **The US chip momentum cooled into the close, and the won firmed further.** Reconciling the settle: the **SK Hynix ADR closed +11% at $169.18** — it **gave back more than half of its ~+23% intraday spike** (my 18Z draft cited the intraday peak; the *settled* close is +11%), so the ~46–50% ADR premium over Seoul is **narrowing off the peak**. The **won extended its gains to ~1,487.68** (its firmest since mid-May, DXY ~100.9) on the soft-CPI dollar, the Hynix conversion flow, and **rising BOK rate-hike expectations**. Korea reopens Wednesday into a setup that is still **chip-supportive** (relief held, HBM4, Tuesday's +3.3–3.7% chip closes) but with the **US momentum fading** — the 06:30Z settle is the real read.

- 🟡 **Korea reopens Wednesday into a chip-supportive setup that cooled at the margin overnight — the SK Hynix ADR settled +11% ($169.18), not the +23% intraday peak — so a follow-through bounce is the base case but momentum is fading.** The constructive read-through from the US session partly held and partly faded. Held: the **dovish-CPI relief kept US chips bid (Nasdaq +0.9% Tuesday)**, SK Hynix is **shipping HBM4 for Nvidia**, and the memory names **closed up Tuesday (Samsung +3.34%, SK Hynix +3.69%)**. Faded: the **SK Hynix ADR gave back most of its intraday +23% to settle +11% at $169.18** — the US bid cooled into the close. For a downstream agent, the finance-ko read: Korea's Wednesday setup is **still net-supportive but less so than the intraday tape suggested** — a follow-through bounce off Tuesday's fragile stabilization is the base case, but the fading ADR momentum + oil + Warsh's cautious tone cap it. Keep it measured: the **open level is RSS-lagged at publish** (direction forming, not confirmed), a US-session chip pop has repeatedly failed to guarantee the Seoul follow-through this week, and the **06:30Z settle is the real read**.
  - evidence: verified on opened primaries — ADR settled [Investing.com: SK Hynix ADR (SKHY) opened $168.11, closed $169.18 (~+11% vs July 13's $152.35), high ~$173 (July 14)](https://www.investing.com/equities/sk-hynix-adr); Tuesday chip closes [Seoul Economic Daily: Samsung +3.34%, SK Hynix +3.69% (July 14)](https://en.sedaily.com/finance/2026/07/14/kospi-swings-but-holds-6800-samsung-sk-hynix-close-up-3); HBM4/US relief [Bloomberg: SK Hynix HBM4 mass production for Nvidia, ADR premium over Seoul (July 14)](https://www.bloomberg.com/news/articles/2026-07-14/sk-hynix-adr-premium-balloons-to-nearly-50-over-korean-shares)
  - uncertainty: 🟡 — the Korea Wednesday open is not yet printed (RSS-lagged; a bounce is the base case, not confirmed); the ADR settled +11% (I corrected the +23% intraday-peak figure from last window); precise US index levels are Scout's `finance` lead
  - follow: `KOSPI Wednesday reopen chip-supportive cooling · SK Hynix ADR settled +11 169.18 gave back +23 peak momentum fading · HBM4 Nvidia demand Tuesday chips +3.34 +3.69 · settle 06:30Z real read`

- 🟡 **The ADR premium is normalizing off its peak — the SK Hynix ADR settled +11% (not +23%), so the "Seoul catch-up" pull into Wednesday is weaker than the intraday tape implied.** Last window flagged the ~46–50% ADR/Seoul premium as a two-sided signal: bullish if Seoul catches up, cautionary if the ADR falls back. The settled close leans **cautionary**: the **ADR gave back over half its intraday spike to close +11% at $169.18**, so the dislocation is **normalizing the way early-ADR premiums usually do — the ADR sliding toward the local, not the local ripping up to the ADR**. For a downstream agent: the huge ADR premium is still a **real US-demand signal** (global money paid up for SK Hynix), but as a *near-term Wednesday catalyst for Seoul* it is **weaker than the peak suggested** — the arbitrage pull is smaller now, and a fading US bid removes some of the follow-through fuel. Watch whether Wednesday's Seoul shares still narrow the gap (bullish) or the ADR keeps normalizing lower (the momentum-cooling path).
  - evidence: verified on an opened primary — [Investing.com: SK Hynix ADR (SKHY) settled $169.18 (~+11%) on July 14, off an intraday high near $173 and well below the ~+23% peak; prior close $152.35](https://www.investing.com/equities/sk-hynix-adr); the ~46–50% peak premium carried from the 18Z Bloomberg read
  - uncertainty: 🟡 — the settled ADR premium off $169.18 is narrower than the ~46–50% peak but I do not have the exact settled gap (depends on Wednesday's Seoul price); "Seoul catches up vs ADR normalizes lower" is still two-sided, just tilted toward normalization after the fade

- 🔵 **The won extended its gains to ~1,487.68 — its firmest since mid-May — on the soft dollar, the Hynix flow, and now rising BOK rate-hike expectations.** The won's sub-1,500 hold is not just holding but **extending**: it firmed to **~1,487.68 (DXY ~100.9)**, its strongest since mid-May. Three forces are now aligned in its favor: the **soft-CPI dollar weakness**, the **SK Hynix $26.5bn USD→KRW conversion flow**, and — newly cited — **rising expectations that the Bank of Korea could hike** (to counter oil-import inflation and defend the currency). For a downstream agent, the finance-ko read: the won has flipped from the week's **binding constraint** to a **tailwind**, and the BOK-hike angle is the first genuinely *domestic* driver to appear in weeks — worth watching, because if it firms into a real policy expectation it would move the won *off* the external dollar switch (the won-switch test). For now the clock stays paused (soft dollar + one-off flow dominate). Risks to the hold: a hotter July CPI on the oil re-spike, the eventual absorption of the Hynix conversion, and whether the BOK actually leans hawkish.
  - evidence: verified on an opened primary — [Trading Economics: USD/KRW ~1,487.68 (won +0.68%, firmest since mid-May), DXY ~100.9; won supported by the SK Hynix $26.5bn listing conversion, soft-CPI dollar weakness, and BOK rate-hike expectations (July 15)](https://tradingeconomics.com/south-korea/currency)
  - uncertainty: 🔵 — the won level is a snapshot (~1,487.68; TE has erred both ways this week, read direction/zone); the BOK-hike expectation is a cited market theme, not a confirmed policy signal; a hot July CPI or flow absorption could reverse the hold
