Core CPI settles the hike — the dots, the expiry and the yen are the trade

Friday 11 September — the CPI print, and a rally that was not about CPI

The BLS printed August headline CPI at +0.4% m/m and 3.4% y/y, both in line, with core at +0.3% m/m against +0.2% consensus and core y/y falling to 2.4%, the slowest since March 2021. The unrounded seasonally adjusted figures are not published; from NSA index levels (333.918 → 334.980 headline, 337.133 → 338.041 core) the monthly rises were +0.318% and +0.269% respectively.

The composition is the argument. Energy +2.1% m/m and +16.3% y/y, gasoline +3.9% m/m and +27.4% y/y, with the BLS stating that gasoline alone accounted for over a third of the monthly all-items increase. Airline fares +2.2% m/m and +23.4% y/y. Against that, shelter was well behaved — OER +0.2%, rent +0.2%, shelter 3.0% y/y; core goods only +0.1%; used cars −2.3% y/y; and medical care services outright negative at −0.2%. The core beat leans heavily on a single line: wireless services +5.9% m/m, which Michael Ashton (via TIPSWatch) argues "basically adds up to the miss on core CPI." This was a war print, not a demand print.

The hawkish counterweight is the Fed's actual target variable. The Cleveland Fed nowcast has August core PCE at +0.27% m/m and 3.40% y/y, and core PCE has run above 3% every month this year. A 2.4% core CPI and a 3.4% core PCE are two different inflation problems, and the Committee reports on the second.

The front end did all the work. The 2-year rose 7bp to 4.63%, trading to ~4.65% intraday and its highest since 2024; the 10-year rose 1bp to 4.96%, approaching but not taking 5.00%; the 30-year actually fell 2bp to 5.35%. That is a bear flattener — 2s10s in to +33bp from +39bp on the day and +41bp on 4 September, and 5s30s to +57bp from +70bp on the week. A 26bp weekly move in 2s against 11bp in 30s is a policy repricing, not a term-premium event, and it is the cleanest shape change in this note.

Equities rallied anyway, and the reason was oil. The S&P 500 rose 0.86% to 7,656.98, the Nasdaq Composite 0.96% to 26,333.04, the Dow 0.98% to 52,573.29 and the Russell 2000 0.45% to 2,903.94, nine of eleven sectors higher, with WTI down 2.4% and Brent down 2.8% on constructive Gulf diplomacy. VIX fell 11.2% to 15.84. Leadership was the AI-infrastructure complex reading through Oracle's Thursday results — Dell +10%, HPE +9%, memory names higher on OCI capacity demand — while Adobe fell 3% and Barclays cut targets across the airlines on jet fuel. Oracle itself is unresolved across sources: prints of +6.98%, +7% and "gave back its early gains" all exist for the same session.

None of it saved the week. The S&P lost 0.80%, the Nasdaq 0.66%, the Dow 1.58% — its worst week since March — and the Russell 2000 2.41%. Small caps carry the rate sensitivity and they told you where the pressure was. Weekly single-stock damage was heavy and idiosyncratic: COO −22.98% on an FY guidance cut, CASY −16.46%, FDS −14.00%, PTC −12.55%, AMGN −12.48%.

Europe and Asia on Friday

Europe ran the same shape — a risk-on session inside a bad week. Stoxx 600 +0.49% to 639.10 (week −1.6%), Euro Stoxx 50 +0.90% to 6,325.13, DAX +0.82% to ~25,569, CAC 40 +0.78% to 8,179.77 (week −1.4%, a fifth straight weekly fall), FTSE 100 +0.4% to 10,650.44 (week −1.7%) on a UK July GDP beat of +0.4% m/m against 0.0% consensus. The tell was in the losers: Rheinmetall −2.5/−3.0% and BAE −1% on a day European equities rallied. The bid was for the Hormuz diplomatic track, not for risk generally. Infineon +4.8%, Siemens +2.5%, Stellantis +3.1%, Safran +2.5% led; Italian banks were strong on the Intesa–MPS and UniCredit–Commerzbank files.

Asia was the weak leg. The Nikkei fell 1.93% to 64,011.34 against TOPIX −0.65% to 4,028.30 — the Nikkei fell more than twice as hard, a high-beta exporter and tech session consistent with the Korea and Taiwan tape. KOSPI −1.76% to 6,910, TAIEX −1.61% to 46,184.85, with Samsung −3.44% and SK Hynix −2.21%. Set that against the fundamentals: Korean exports in the first ten days of September rose 83% y/y with semiconductor shipments up 270%. The AI complex is selling off on rates and oil, not on demand. In China, Shanghai −1.18% to 3,888.11, CSI 300 −0.84% to 4,510.16, Shenzhen Component −1.08%, with Hang Seng −0.60% to 24,806 and HS Tech −0.23% but −5.46% on the week, the sharpest weekly move anywhere in Asia. The Hong Kong internet complex is in a serious drawdown: over the prior month JD Logistics and Kuaishou each fell around 26%, with Meituan, Shenzhou International and Trip.com each off more than 18%.

Weekend 12–13 September

The Gulf. The Saudi East–West pipeline — the principal workaround for Hormuz, nameplate ~7m bpd, carrying 4–5% of global supply — was struck by drones on Thursday 10 September and shut precautionarily, with damage at at least eight places. The attack originated from Maysan province in south-eastern Iraq: Baghdad seized the launch platform, dismissed the Maysan operations commander and the provincial police chief, and has allowed Iran to join the inquiry. Saudi Arabia chose not to retaliate, at Baghdad's request. Trump publicly blamed Iran — a claim neither Riyadh nor Baghdad has made, and that gap is the key de-escalation variable. On Sunday an Iranian commercial vessel was struck near Hengam Island at ~05:00 local, killing one crew member and wounding four; the attacker is unidentified and there has been no US statement. Trump spoke with Crown Prince Mohammed bin Salman on Saturday ("it's going to work out fine and dandy") and declined his request for direct US strikes on the Houthis, offering intelligence and targeting support instead. Meanwhile the Houthis completed the seizure of Mokha and Mayun (Perim) Island, placing forces about 20km from Africa and effectively giving them Bab el-Mandeb — a strait carrying ~12% of global trade, 11% of maritime oil and 8% of LNG, where volumes were already down 50–55% on 2023–25. Saudi–Houthi strikes were traded across the strait over the weekend and the Houthis are reportedly advancing on Marib.

The diplomacy, which is today's event. GCC and Iranian foreign ministers meet in Salalah, Oman, today, Monday 14 September — the first such gathering since February, with Iraq attending and Bahrain declining on the grounds that it will not join a collective meeting including Iran before diplomatic relations resume. Iran will present an Iran–Oman agreement on a new Hormuz route, with Foreign Minister Araghchi promising "details of the agreement with Oman and maps related to the new route." A senior Iranian source stated the Strait has not been reopened. Iran's negotiating position is weak and getting weaker: inflation 89% y/y, food inflation 127%, the rial at an all-time low of 1.37m/USD before recovering to ~1.31m, and the blockade has halted most oil exports.

Credit. The most market-relevant weekend item is what did not happen: there is no 12–13 September S&P report warning of imminent hyperscaler downgrades or naming Oracle for a cut into junk. The real report is dated Friday 11 September, says hyperscaler credit quality is "gradually weakening," names Amazon, Microsoft, Alphabet, Oracle, SpaceX and Meta, forecasts more than $7trn of data-centre and AI spend through 2030, and raises a genuinely new concern: hyperscalers using their own ratings to help weaker entities borrow cheaply — startups including Anthropic and OpenAI, smaller cloud operators, municipalities — via leases, loan backstops and equity stakes, creating "an opaque secondary lending market." That is arguably more actionable than the headline that was circulating. Separately, SoftBank opens a roadshow today (14–17 September, at Citigroup in New York) for a $10–20bn high-yield bond, having drawn $25.9bn of a $40bn OpenAI bridge that repays tomorrow.

Europe and Russia–Ukraine. Sweden voted Sunday; SVT's exit poll has the left bloc at 51.3% against the right bloc's 46.8%, with the Social Democrats at 28.4% and — the headline — the Sweden Democrats down 3.0 points to 17.2% and losing 12 seats. Magdalena Andersson would displace Ulf Kristersson. No official count exists; certification is expected 19–20 September. In Ukraine, 863 Ukrainian drones over 24 hours against 389 Russian drones shot down, at least four killed and twenty wounded; Russia struck power sites while Kyiv hit a refining hub; two killed near the Zaporizhzhia plant. Two near-misses on the Polish border — a truck struck 0.8km from Poland and a Russian drone hitting a Warsaw-bound train. Peskov did not rule out three-way talks in October. Most significant for this note: Trump has told Kyiv to stop striking Russian diesel. With Hormuz shut, Russian refined product has become systemically important to the West and Washington is now restraining Ukraine to protect it. The two energy theatres have merged.

Asia. At the 18th BRICS summit in New Delhi, the New Delhi Declaration called for "maximum restraint" in the Middle East — the phrase belongs to the communiqué, not to Xi personally, who separately said the war "does not serve the common interests." Iran and Saudi Arabia are both BRICS members. Xi walks from that summit into a White House summit with Iran on the agenda, reported for late September.

No Monday indicative opens exist at this hour. FX reopens from roughly 07:00 AEST and index futures from 08:00 AEST; the ASX 200 futures contract rolled to December over the weekend, so the 8,805 print carries a different dividend and carry basis from Friday's 8,741.20 cash close and is not a 64-point indication. Crypto is the only continuously traded read: BTC $77,270, +3.4% on the week after twice rejecting $79.8–79.9k.

Fed detail — the dots are the event. Chair Kevin Warsh presides over a Committee that dissented three times for a hike in July and now has an 85.5%-priced move. The decision is therefore not tradeable; the projections are. Current pricing embeds two hikes by December as the modal outcome (47.3%), a 27.4% tail on three, and — the striking part — no cut at any 2026 meeting on either tracker. A median dot that stops at 4.00–4.25% is dovish against that strip. Two other things to watch. First, Governor Lisa Cook is a sitting, voting governor: the Supreme Court upheld her 5–4 in June and the White House's August removal notice has produced no reported outcome, so a Cook dissent would read as a governance story as much as a policy one. Second, the blackout has been verified rather than assumed — the Board's last speech was Waller on 3 September, and Bowman on Friday 18 September at 09:30 ET is the first voice afterwards.

BoJ detail — the widest pricing disagreement of the week. The decision is Friday 18 September, confirmed against the BoJ's own schedule; the 17th is the meeting start and at least two third-party calendars still get this wrong, for the fifth consecutive edition. What is priced spans 61.7% to 90% across three sources stamped the same day — do not size off a single tracker. Reuters (10 Sep) reports a hike to 1.25% with the Board offering "no preset idea on the terminal rate", which is the explicit setup for a dovish hike; Masu is quoted saying underlying inflation is "about to reach 2%, but we don't see it sharply overshooting." Two complications. August national CPI prints roughly three and a half hours before the decision, with headline expected to accelerate to 2.1% on oil while core holds at 1.8% — a board hiking on an energy-driven headline with core flat is genuinely contestable. And Tokyo is shut 21–23 September, so whatever Friday produces has no domestic session to absorb it for three days. That is gap risk, not drift risk, and it is the reason to size the yen short smaller rather than to abandon it.

RBA detail — the market and three of the four majors disagree on the date. Cash rate 4.35%, decision Tuesday 29 September. Hike probability is 76% (verified by direct fetch, 13 Sep) from 70% a week ago, with roughly one full hike priced across the next three meetings and a 4.60% terminal by December. All four majors now agree on 4.60%; only NAB is with the market on timing, forecasting September and November, while Westpac — which flipped on 8 September, the last of the four — CBA and ANZ all call November. That is a clean dispersion: either the market is wrong about the date or three of the big four are. The domestic data has been uniformly bad — consumer sentiment 84.4, −5.2%; NAB business conditions −5, the first negative reading in six years, with purchase costs +2.3% q/q against product prices +0.8%. And the calendar matters: the Board does get August employment on 24 September, correcting No. 005, but does not get September CPI, which lands 30 September, the morning after. That asymmetry is exactly the Westpac/CBA argument for waiting.

ECB detail — the hawkish impulse peaked on decision day. Four speakers since Thursday all pulled in the same direction. Makhlouf called the hike a "measured response" but warned that "substantially more tightening could impose meaningful economic costs"; Kocher put a clock on it, saying inflation must return to target "within about a year" and any overshoot "must be brief"; Econostream's own tone meter reads "hawkish bias eases." That argues the 28–29% October pricing is closer to right than the 61% carried last edition, and we publish the lower figure with the caveat rather than a range. The spread picture is unresolved: OAT–Bund is quoted at 89.8bp by a dedicated spread source and ~95bp derived from vendor yields, and the "widest since 2012" claim made when V025 was opened on Friday could not be re-verified and is withdrawn. BTP–OAT has compressed from −17bp to −9.6bp as Italy rallied 3.6bp against a 1.4bp OAT selloff — though at thirty years France still pays 10bp more than Italy.

Closed today — V001 US 2-year, SCRATCH. Opened 7 September at 4.37% as an explicit coin flip "decided by CPI 11 September." CPI came, core printed +0.3% — between the ≤0.2% receive trigger and the ≥0.4% payer trigger — and the view resolved by its own terms without taking a side. The 2-year is now 4.63%, +26bp on the week. A neutral stance through a 26bp move is a scratch, and the honest accounting is that it cost the book the single cleanest directional move of the week. We are not re-opening it, and the reason is the lesson this ledger wrote on Friday: every view that expressed a structural mechanism worked and every view that expressed a tactical level did not. Fading a 97.4% cumulative hike probability two days before an SEP meeting is a level trade. We stay flat and say so.

Closed today — V021 Korea / Taiwan semis, RIGHT. Opened 8 September to trim into a melt-up after a +4.61% session on a model headline, with long semis the most crowded trade in the market. Both legs are now below entry: KOSPI 6,910 against 6,995.39 (−1.22%), TAIEX 46,184.85 against 47,326.27 (−2.41%). The published trigger — a break of the 7,052 high on volume — never fired. The reason to close rather than extend is the fundamental data: Korean exports in the first ten days of September rose 83% y/y with semiconductor shipments up 270%. The complex de-rated 1–2% on demand growth like that, which means the selloff is duration, not deterioration. The crowding that justified the trim has been worked off; staying short into a 270% shipment number would be a different trade with a worse thesis.

Opened today — V026 long Brent–WTI, entry $4.56, Low conviction, 1–3 months. This exists because of Friday's accountability note. V024 was criticised in this ledger for replacing an expression-based exit with an absence of one rather than a cheaper expression of the same thesis. This is that cheaper expression. The chokepoint thesis has been right since edition one; the flat-price expression became expensive and was dropped; the spread is where the same risk is now demonstrably unpriced, at a level 24 cents narrower than before Hormuz collapsed to single-digit transits. Conviction is Low deliberately, because the honest alternative explanation — that US distillate tightness at 1982-low August stocks is bidding WTI as feedstock on its own merits — is a real one and is written into the invalidation.

Not opened, and why. The diesel crack has been named as the right answer in two consecutive editions and is still not on. It stays off, because its published assessment is ten days stale — the freshest mark is $101.1/bbl on 4 September, across exactly the week crude rose 8.65%. This ledger closed V007 on the principle that a view that cannot be scored is worse than a view that was wrong. That principle binds here too: no diesel crack view until a markable assessment exists. The copper 232 option is now genuinely cheap at a near-zero arb, and is also not opened — there is no report date, and this desk has already been wrong twice building copper trades on policy optionality.

Scorecard. Nineteen open, seven closed to date: two right, two wrong, three scratch. On decided views that is 2 of 4, up from 1 of 3, on a sample still far too small to mean anything. Working today: V017 credit (the cleanest, and the decompression is now visible in the data), V006 ASX (−2.94%), V016 iron ore (fourth session sub-$100), V005 S&P, V004 ACGB flattener, V023 AUD/NZD, V011 EUR/USD, V022 copper. Against us: V003 5s30s, twelve basis points from its stop; V009 AUD/USD; V025 OAT–Bund, where the entry level itself is disputed.

Portfolio-level read. Friday's pattern — mechanism trades work, level trades do not — held for a second week, and it now has a corollary worth naming. The three positions that changed most this week changed because of positioning data, not price: the yen short lost its fuel, gold became the most crowded long in the market, and energy turned out to be the one place nobody is positioned. That argues for sizing off the COT rather than off conviction in the week ahead. Into a Fed that is 85.5% priced, a BoJ spanning 62–90%, a BoE that has moved 18 points in a week, a record expiry and a gamma flip 0.75% below spot, the book should carry less gross and more convexity than it did on Friday — and the single trade most in need of a smaller number next to it is the one this desk has been most right about.

These are analytical framings for a professional reader, expressed in the vernacular of a macro desk; they are not personalised investment advice and carry no position sizing. The "what changes the view" column is the accountability mechanism — each view is logged and scored in the project's views ledger.

The one-line read. The market is structurally long, mechanically leveraged, and about to lose both of its largest supports — the buyback bid and expiry-pinned gamma — in the same week as an 85.5%-priced hike that Polymarket prices at 78%. Positioning is the vulnerability; earnings are the defence, and the defence is genuinely strong: estimates revised up into an energy shock on a multiple below its five-year average. Do not treat the bear case as settled. But the level to watch is 7,600, and the trade with the least crowding against it is energy.
