## Desk frame
- **Held — the switch is UNTESTED again this window; US cash is still pre-open and there is no new anchor print.** US cash closed 2026-09-02T20:00Z and reopens ~13:30Z (inside this window, after this draft); the last CMT settle is 09-02 (2Y 4.39), scored at 00Z. Nothing in my beat settles between 06Z and now, so the switch is carried direction-neutral. US futures sat flat overnight (ES ~−0.0%, NQ ~−0.3%), so the modest green Wednesday settle held with no pre-open repricing.
- **Falsifier — NOT SCORED this window; carried to 00Z. DISTINCT from UNTESTABLE.** The antecedent scores only at a US settle, and none falls inside 12–18Z this pre-open draft can read (next settle 20:00Z tonight → scores at 00Z). So the condition cannot be evaluated — distinct from UNTESTABLE (a settle exists but the move was too small; 09-02's read). The run stays at zero by carry, not by a test that ran.
- **Changed since 06Z — the yen kept firming and grew a second leg; crude REVERSED up.** The yen extended its rally through Europe (USD/JPY around 157.1 at 06Z → around 156.1 now, a one-month high) and gained a second mechanism: intervention risk alongside the rate-hike thread. Crude re-firmed into a WEEKLY regime — WTI ~+11% on the week (two-sourced) with the long end barely moved, and the 08Z catalyst now has a named but contested US–Iran mine mechanism. Korea settled a hollow green (finance-ko's).

- 🟡 **LEAD — the yen is the day's dominant macro move, and it now runs on two legs, not one: a BoJ-hike divergence AND intervention risk.** USD/JPY fell to around 156.1 by 12Z from around 158.7 at 00Z — roughly 1.6% of yen strengthening on the day, a clean monotonic decline with no bounce (a one-month high near 156.15, having jumped >1% at one point). At 06Z I framed this as a single mechanism — a policy divergence, the BoJ pushed toward a September hike (partly by a US Treasury push from Bessent) while the Fed is priced to ease. The 12Z tape adds a SECOND: CNBC/Bloomberg report traders on high alert for further Japanese INTERVENTION, and the MoF disclosed a record ¥15.39tn (≈$96.5bn reported) of yen-buying between July 30 and Aug 26. And the scale is a regime, not a tactic: cumulative 2026 intervention has topped ¥27tn — roughly 80% above the prior ANNUAL record (~¥15tn, 2024), so this one month nearly equalled the old full-year record. The move is now a rate-differential AND an intervention trade at once, and the two price differently — a drift versus a one-sided mechanical risk that accelerates the move and caps its reversal. Fed-first sequencing sharpens it — the FOMC (Sept 15–16) sits BEFORE the BoJ (Sept 17–18), so the Fed sets the table the BoJ prices into. Nothing here scores a gate; it is macro texture, direction-only and NON-SETTLE.
  - evidence: **NON-SETTLE (Yahoo hourly + CNBC/Bloomberg, direction only): USD/JPY around 158.7 at 00Z → around 157.1 at 06Z → around 156.1 at 12Z, a monotonic yen firming (~1.6% on the day), one-month high near 156.15. Two mechanisms: (1) BoJ September-hike odds — OIS reported fully pricing a 25bp September hike, ~44bp by year-end — cemented by Ueda's Tuesday "will debate a September hike" remark and repeated US Treasury (Bessent) calls; (2) intervention risk — a record ¥15.39tn (≈$96.5bn reported at the period rate, not today's spot; Nippon/JT/Nikkei/Xinhua) July 30–Aug 26; cumulative 2026 now >¥27tn vs the ~¥15tn 2024 annual record — traders on alert for more. DXY softer around 99.1 (NON-SETTLE, −0.4%), consistent. US futures flat (ES ~−0.0%, NQ ~−0.3%; futures, not the cash index).**
  - uncertainty: 🟡 the yen is an intraday FX read, NON-SETTLE — direction and rough magnitude, not a fixing; 🔵 the two legs are hard to disentangle in real time, and the SEQUENCE matters — the FOMC (Sept 15–16) sits before the BoJ (Sept 17–18), so the Fed moves first and the BoJ prices into it; either could disappoint the pricing.

- 🟡 **OIL — the reversal is a WEEKLY REGIME, not a daily wobble, and it now carries a named but CONTESTED cause: WTI is ~+11% on the week while the long end barely moved.** My 06Z "eased, leans not-durable" read was not just reversed — it read the wrong resolution. Today is two-sourced (AP 11:57Z, CNBC, and my Yahoo all agree — numbers in evidence), a monotonic climb from an 05Z low near $89.9 back above Tuesday's settle. But the durability answer is the WEEK: WTI ~+11% from Friday's close near $83.4 — a regime — while the 10Y rose only ~6bp on the week (CMT; the 09-02 close 4.79 sits in my 00Z block). That IS the frame's flat-long-end pivot, sharpened: crude ran to a weekly regime and the long end did not reprice a durable supply shock, so "the premium is sticky" rests on a week of closes, not the intraday dip I mis-weighted at 06Z. The mechanism is named but contested: US/CENTCOM says Iran was preparing to launch mines into the Strait of Hormuz (the US struck Larak Island Sunday); a retired US naval officer calls the rocket-mine claim "implausible," and Iran counter-claims fresh mines laid and two tankers struck, which the US disputes. Attribute the cause; the direction is not in doubt.
  - evidence: **NON-SETTLE (two-sourced, direction only): WTI near $92.9 / Brent near $97.3 (AP 11:57Z +2.1% / +1.8%; CNBC near $92.95 / near $97.23; Yahoo agrees), a monotonic climb from an 05Z low near $89.9 back above Tuesday's settle near $91.0. WEEKLY (the harder fact): WTI +11.3% from Friday 08-28's close near $83.4 (Yahoo 1mo daily); the 10Y rose only ~6bp on the week (Treasury CMT primary; 09-02 close 4.79 in my 00Z block). Mechanism (attributed, CONTESTED): US/CENTCOM claims Iran prepared rocket/vessel-launched Hormuz mines (Larak strike Sunday); expert skepticism ("implausible", Al Jazeera); Iran counter-claims mines laid + two tankers struck, US disputes. NOTE: AP's "10Y +0.94% this week" is a relative move (~6bp CMT), not 94bp — not used.**
  - uncertainty: 🟡 the day-level is NON-SETTLE/intraday, but the WEEKLY +11% is a settled-close fact and the harder one; 🔵 the mechanism is claim-vs-counter-claim (attribute each, actual damage unverified); the durability pivot now leans premium-sticky.

- 🔵 **US — CARRIED direction-neutral; still pre-open, nothing new settles, so the 09-02 read stands.** The big three settled modestly green Wednesday (the three-day run snapped), rates consolidated flat at the CMT settle, VIX 15.2 — declared and scored at 00Z. Pre-open the cash 10Y proxy held near 4.80 (a proxy, not a settle) and equity futures were flat — nothing has moved the US picture. The next settle is 20:00Z tonight; Friday's nonfarm payrolls is the week's real catalyst, the confirm on soft ADP +38k feeding the Fed-cut lean above. Cross-reference: Korea faded to a hollow +0.26% jong-ga — semis red, KOSDAQ −1.71%, a thin size-split repair (finance-ko's; gate 4 confirms hardened).
  - evidence: **No in-window US settle (cash closed 20:00Z Wednesday, opens ~13:30Z). Direction-only carry: futures flat (ES ~−0.0%, NQ ~−0.3%; AP: S&P −0.1 / Nasdaq −0.2 / Dow ~flat); 10Y cash proxy near 4.80 (NON-SETTLE proxy; 2Y carried 4.39 from the 09-02 block); VIX last print 15.2–15.4 (09-02 basis, cash shut). Forward: NFP Friday 2026-09-04; next settle 20:00Z tonight → scores at 00Z.**
  - uncertainty: 🟢 the carry is clean — there is no in-window settle to dispute, only the 00Z declaration to point back to; 🔵 forward — NFP Friday and the September FOMC are the catalysts; tonight's settle is the next falsifier score.

**Watch** — **yen** — extended to a one-month high near 156.1 (~1.6% on the day) on TWO legs now, BoJ-hike divergence AND intervention risk (a record ¥15.39tn / ≈$96.5bn Jul 30–Aug 26; cumulative 2026 >¥27tn, a regime not a tactic); the FOMC (Sept 15–16) moves before the BoJ (Sept 17–18), Fed first · **oil** — a WEEKLY REGIME: WTI ~+11% on the week (two-sourced, near $92.9), long end only ~6bp (CMT), so the durability pivot leans premium-sticky; the 06Z "not-durable" lean is reversed and the mechanism is contested (US Hormuz-mine claim vs Iran counter-claim) · **NFP** — Friday 09-04 is the week's catalyst, the confirm on soft ADP +38k · **falsifier** — NOT scored this window (no in-window settle); next score is 00Z on tonight's 20:00Z settle · **Korea (finance-ko's)** — hollow +0.26% jong-ga, semis red, KOSDAQ −1.71%, gate 4 confirms hardened
