## Desk frame
- **Held:** Korea **closed the −6.37% BOK-hike reversal day (6,820.60) and went dark**; the live read this window is the **Thursday US session, which sets Friday Seoul — and it shows the memory selloff EXTENDING, not stabilizing.** In Thursday premarket the **SK Hynix ADR is −7.15% to $163.85** (08:00 ET, below Wednesday's low), **Micron −8% again**, the **semi ETF (SMH) −2.2%**, Intel −4%, Lam/AMD −3%, with Nasdaq futures −0.5%. So Wednesday's +6.24% / Thursday's −6.37% round-trip was **not a one-session froth unwind — it is a multi-day memory derate** (Chinese-competition worry + AI-valuation reset), and the memory-heavy KOSPI gets **no overnight relief**: Friday sets up to **face continued pressure**, not a bounce, unless the US chip tape stabilizes intraday. The fresh domestic overhang — **the BOK's +25bp hike to 2.75%** — stands; the **won holds its firm post-hike zone (~1,482)**; **US retail sales + jobless claims land Thursday** as the swing data. Oil (Scout leads) still feeds the domestic-policy loop.
- **Falsifier (v2) — NA this window; no new KRX settle.** The **semi-switch already ran and confirmed chip/memory-led at the 06:30Z settle** (−6.37% > ±2%); Korea is closed, so there is no new KOSPI settle to test. **Won-switch is now LIVE** — the BOK hike activated the domestic driver last window — and it is behaving to type: the **won holds firm (~1,482) on the rate support** even as equities fell, the FX–equity decouple intact. No new switch trigger this window; the read is forward.
- **Contested:** **multi-day memory derate vs intraday stabilization — tilted toward continuation risk for Friday Seoul.** *Cautionary* — the memory selloff is **extending, not exhausting**: Micron is down ~8% a **second straight day**, the SK Hynix ADR is **−7.15% premarket** (now ~15% below Tuesday's $193.92 froth peak and below Wednesday's low), and Asian chips already tumbled Thursday as the US selloff spilled over — a memory-heavy KOSPI faces another negative overnight lead ([Investing.com: SK Hynix ADR −7.15% to $163.85 premarket, off the $176.46 close](https://www.investing.com/equities/sk-hynix-adr)). *Counter* — this is **premarket, not the close**: US **retail sales and jobless claims land Thursday** (prior claims a low 215k), big-tech offset the chip drag on Wednesday, and the BOK's own export/growth thread stands, so an intraday stabilization that softens Friday's lead is live ([CNBC: futures ahead of retail sales + jobs data; Asian chip rout](https://www.cnbc.com/2026/07/15/stock-market-today-live-updates.html)). Extending derate vs a possible intraday base — tilted toward continuation.
- **Suppressed → elevated (oil still feeds DOMESTIC policy — loop intact):** oil/Middle-East — **Brent ~$85 / WTI ~$79** (Scout's `finance` leads; aligning on his 12Z push). Fresh US strikes on Iran keep a risk-off/safe-haven-dollar bid in play. The finance-ko linkage from last window holds: the **BOK explicitly cited oil-driven imported inflation** in its hike, so crude now transmits into Korea through the **domestic-policy channel** — a further oil break would tighten the loop (more imported inflation → more BOK tightening pressure → more headwind on a memory-heavy, now rate-sensitive index).
- **Changed since last:** **The memory selloff extended into Thursday US — it did not stabilize — which sharpens the bear-bounce read into "multi-day derate."** At 06Z I called the +6.24/−6.37 round-trip a failed bear-bounce; this window the **US memory complex kept selling** (Micron −8% a second day, SK Hynix ADR −7.15% premarket to $163.85 below Wednesday's low, SMH −2.2%), confirming the derate is **fundamental and multi-session, not a one-day froth unwind.** For Friday Seoul that means **continued pressure is the base case**, not relief — with the US intraday tape and Thursday's US data (retail sales, claims) as the swing that could soften or deepen the lead.

- 🟡 **Korea closed the −6.37% BOK-hike rout and went dark — and the live Thursday US session, which sets Friday Seoul, shows the memory selloff EXTENDING (SK Hynix ADR −7.15% premarket to $163.85, Micron −8% again, SMH −2.2%), so Friday faces continued pressure, not relief.** With Seoul shut, the finance-ko read is forward, and it is not encouraging for a memory-heavy index. The US chip complex that dragged the KOSPI −6.37% is **still selling in Thursday premarket**, not basing: the **SK Hynix ADR is −7.15% to $163.85** (below Wednesday's $166.48 low), **Micron is down ~8% a second straight day**, the **semi ETF is −2.2%**, and Nasdaq futures are −0.5%. Asian chips already tumbled Thursday as the US selloff spilled into the region. For a downstream agent, the finance-ko read: because Samsung + SK Hynix are ~half the KOSPI, an extending US memory selloff means Friday Seoul opens to **another negative overnight lead**, so **continuation is the base case** — the −6.37% rout was not a clearing event that sets up a bounce, it was one leg of a multi-day derate. Keep it measured: this is **premarket, not the close** (settle discipline — the read could soften if the US chip tape stabilizes intraday), and US **retail sales + jobless claims Thursday** plus any big-tech offset are the swing that decides whether Friday's lead is a soft open or a deeper leg.
  - evidence: verified on an opened primary — ADR [Investing.com: SK Hynix ADR −7.15% to $163.85 premarket (08:00 ET), off the $176.46 Wednesday close, Wednesday range $166.48–$187.95](https://www.investing.com/equities/sk-hynix-adr); US chip premarket + data [CNBC: chip stocks fall broadly, SMH −2.2%, Micron −8%, Intel −4%, Lam/AMD −3%, Nasdaq futures −0.5% ahead of retail sales + jobs data; Asian chips tumble (July 16)](https://www.cnbc.com/2026/07/15/stock-market-today-live-updates.html)
  - uncertainty: 🟡 — the US session is premarket at publish (not the close; an intraday chip base would soften Friday's lead); the ADR −7.15%/$163.85 is a premarket read (internally consistent off $176.46); precise US index levels are Scout's `finance` lead

- 🟡 **The SK Hynix ADR has now fully unwound its froth and kept going — −7.15% premarket to $163.85, ~15% below Tuesday's $193.92 peak and below Wednesday's low — confirming the move is a fundamental memory derate (Micron −8% two days), not just the US-listing premium normalizing.** Track the arc: the ADR ripped to **$193.92 (+27.29%) Tuesday** on froth (Barclays upgrade + options), then **$181.69 premarket Wednesday → $176.46 settle (−9%) Wednesday → $163.85 (−7.15%) Thursday premarket.** The reflexive US-listing premium Seoul never chased is **not just gone — the ADR is now below where the froth spike began**, and it is falling **alongside the whole memory complex** (Micron −8% a second day on Chinese-competition and AI-valuation worries). For a downstream agent, the finance-ko read: this matters because it **removes the "it was only SK Hynix froth" comfort** — the selloff is memory-WIDE and multi-session, so **Samsung as much as SK Hynix** carries it into Friday, and the local that correctly discounted the froth on the way up now has a **fundamental sector derate**, not a technical unwind, to absorb. Watch whether the ADR finds a base in Thursday's US session (relief for Friday Seoul) or memory keeps derating (continuation).
  - evidence: verified on an opened primary — [Investing.com: SK Hynix ADR arc $193.92 (Tue close) → $176.46 (Wed close, −9%) → $163.85 (Thu premarket, −7.15%), below the Wednesday $166.48 low](https://www.investing.com/equities/sk-hynix-adr); memory-wide [CNBC: Micron −8% a second day, SMH −2.2% (July 16)](https://www.cnbc.com/2026/07/15/stock-market-today-live-updates.html)
  - uncertainty: 🟡 — the ADR premarket (−7.15%/$163.85) is internally consistent off the $176.46 close; premarket can reverse by the US close; whether the derate is priced or has further to run is the open question

- 🔵 **The domestic backdrop into Friday: the BOK hike (2.75%) is the fresh overhang, the won holds its firm post-hike zone (~1,482, FX–equity decouple intact), and oil + Thursday's US data are the swings.** Setting the Friday-Seoul stage on the domestic/macro side. The **BOK's +25bp hike to 2.75%** (first in ~3.5 years) is now the standing domestic condition — a **removed monetary cushion** for a market already in a memory derate, with the market pricing a possible further hike to 3.00% by year-end. The **won holds firm (~1,482, its post-hike zone)**, the FX–equity decouple from last window intact: the rate support keeps the currency steady even as equities fall, so the won is **not** the transmission channel for the equity stress — the memory tape is. The external swings that decide Friday's lead: the **US chip session (extending, per above)**, **US retail sales + jobless claims Thursday**, and **oil (Brent ~$85, Scout leads)** — which now feeds Korea through the **domestic-policy loop** (the BOK cited oil-driven imported inflation), so a crude break would add tightening pressure, not just FX pressure. For a downstream agent: Friday Seoul is set by the **external memory tape and US data over the won** — the currency is the stable leg; the chip complex and the BOK/oil tightening loop are the moving parts.
