Our forecasting track record

What changed, in plain words

• Oil: Brent crude fell about 5% to $83.25 a barrel and US crude fell more than 6% to $79.32, after President Trump called off a planned strike on Iran late on Sunday and said talks would restart. Iran's foreign ministry denied that any direct US talks were scheduled, but confirmed it is negotiating with Oman over a temporary safe route through the Strait of Hormuz. Petrol futures fell 3.9% and heating oil 4.3%. — The war did not end, but the risk of it getting worse this week went down, and the price of oil fell with it.
• Chips: One trading session after its largest-ever daily gain, Korea's KOSPI closed at 6,257.45, down 5.12%. Samsung Electronics fell 8.19% and SK hynix 7.92%. Foreign investors sold a net 1.11 trillion won and institutions 247 billion won, while individual investors bought a net 1.32 trillion won. Shinhan cut its Samsung target to 450,000 won from 590,000 and its SK hynix target to 2.7m from 4.2m; Samsung Securities cut both as well. — The memory-chip trade that has driven markets for a month is now lurching in both directions, and the people who sold today were the big institutions while ordinary savers bought.
• Japan: Tokyo and Washington confirmed they carried out a rare joint yen-buying intervention late last week, and Japan's finance ministry said it would not hesitate to act again. The yen rose as much as 1.4% to a four-week high of 155.20 per dollar, on top of a 3.8% jump over the previous two sessions, after trading near a 40-year low in late July. The Nikkei fell 2.2% to 62,956.48 and the Topix 2.8%, with 212 of the Nikkei's 225 members lower; Toyota fell 5.3%. — Two governments spent money together to push the yen up. A stronger yen makes Japanese exporters worth less, so Japan's market fell while most others rose.
• US factories: The July ISM manufacturing survey, released this morning, came in at 55.6% — up 2.3 points on June, above the 54.0 expected and the strongest reading since May 2022. Production jumped to 58.5 from 52.2, and the employment component returned to growth at 52.8, its first expansionary reading in nearly three years. — American factories had their best month in four years. Good for jobs, but it also makes it easier for the Fed to argue that interest rates should go up rather than down.
• Interest rates: The debate is still about a rate rise, not a cut. The Fed held at 3.50–3.75% on 29 July on a 9–3 vote, with three officials wanting an immediate increase. Market-implied odds of a September increase are elevated but the published numbers disagree sharply with each other — trackers cited between roughly 32% and 82% for the same day — so we treat the direction as established and the precise odds as unverified. — Borrowing costs are more likely to rise than fall this autumn, but nobody can tell you reliably how likely.
• Gold and the dollar: Gold barely moved, at about $4,029 an ounce (−0.35%), and the dollar index was near flat at 99.84. A major military de-escalation would normally knock gold down more than that. — Gold held its ground on a day it might have been expected to fall — a sign that people are buying it for reasons beyond this particular war.
• Jobs: The labour gauge reads calm. Weekly unemployment claims were 197,000, and the four-week average of 202,750 is 8.9% *below* the prior four weeks. Unemployment is 4.2%. June payrolls were a soft +57,000; the July report lands Friday and job-openings data on Tuesday. — Fewer people are filing for unemployment help than a month ago. Hiring is slow, but nobody is losing their job in unusual numbers.
• Trade policy: No new US tariff action. The 10% and 12.5% Section 301 duties covering 60 economies, in force since 24 July, remain in place unchanged. — Nothing new to pass on to consumer prices from tariffs this week.
• On the radar (monitored, never traded): Memory names extended their fall in US pre-market trade — SK hynix's listing down more than 3% and Micron more than 2% — while in Tokyo, memory maker Kioxia rose about 10% on a share buyback and chip-equipment names Tokyo Electron and Advantest fell. Copper was steady at $6.45 a pound. — The chip weakness is not confined to Korea, but it is not uniform either — the companies buying back their own shares went up.

Headline — a geopolitical unwind, a chip air-pocket, and a currency defended by two governments

The day's largest single driver was the removal of a tail risk rather than the arrival of one. Trump said late Sunday that he had called off a planned strike on Iran at the urging of Saudi Arabia, the UAE and Qatar, and that negotiations would restart. Crude repriced immediately: Brent −5.32% to $83.25, WTI −6.32% to $79.32, gasoline −3.93%, heating oil −4.29%. That unwinds part of a July in which Brent rose roughly 24%, its strongest month since March. Note what has and has not been established. Iran's foreign ministry explicitly denied that direct US talks were scheduled; what is confirmed is an Omani channel on a temporary safe passage through Hormuz. The market has priced a de-escalation that only one of the two parties has described.

The supply side quietly improved alongside the politics: OPEC+ approved another modest quota increase, completing the restoration of the cuts introduced in 2023; Turkey and Iraq extended a pipeline agreement by a year; and Kazakhstan resumed intake through the Caspian Pipeline Consortium. Those are single-sourced in today's market wrap and are flagged accordingly.

The running semiconductor theme took the opposite turn. After Friday's +17.91% — the largest one-day gain in the KOSPI's history — the index fell 5.12% to 6,257.45 on Monday, with Samsung and SK hynix both down roughly 8%. The flow composition is the part worth recording: foreign investors sold ₩1.11tn and institutions ₩247bn while individuals absorbed ₩1.32tn. Broker targets were cut hard in the same session — Shinhan took SK hynix from ₩4.2m to ₩2.7m, a 36% reduction. Samsung Securities' analyst attributed the fall not to demand peaking but to "an excessive concentration of investment ahead of a memory boom." Whether or not that read is right, positioning-driven violence of this size in the two largest stocks of a major index is itself the signal.

The genuinely new information is monetary. Tokyo and Washington confirmed a joint yen-buying intervention executed late last week — co-ordinated intervention by the US Treasury is rare and is not undertaken to fine-tune an exchange rate. The yen reached 155.20, a four-week high, having sat near a 40-year trough days earlier. Japanese equities took the hit: Nikkei −2.2%, Topix −2.8%, 212 of 225 constituents lower, transport equipment −5%. Korea's won also firmed 1.0% to 1,428.46, and Seoul commentary framed the move as Korea–US–Japan co-ordination. This belongs to the sovereign/rates thesis, not the equity one.

Against all that, the systemic gauges did not move. The deterministic credit-and-curve gauge reads calm on both legs: the 2s10s slope at +0.47pp (31 Jul) with no re-steepening event, and high-yield spreads at 2.84pp (30 Jul) with no widening flag. VIX opened at 16.82 against a one-month range of 14.96–20.88. The labour gauge is likewise calm, with claims falling. The US tape rallied — S&P proxy +0.93%, Dow +1.27% — and the 10-year sat at 4.693%.

The one macro complication is that today's other release cut against the disinflation story the oil move implies. July ISM manufacturing printed 55.6, the strongest since May 2022, with production at 58.5 and employment back in expansion for the first time in nearly three years. Cheaper energy pulls the September rate decision one way; a manufacturing economy running this hot pulls it the other.

Fact-check log

Standing theses — where the evidence moved

• #6 Energy & critical commodities — DISCONFIRMING signal, logged as a prediction. Today is the strongest peace-dividend evidence of this cycle: a cancelled strike, an Omani passage channel, OPEC+ completing its cut restoration, alternative export routes (Turkey–Iraq, CPC) reopening, and Brent −5.3%. The thesis says the supply premium persists; the honest test is whether it drains. Escalated as P-0061 (Brent settles below $75 on any day by 4 Sep, p=0.25). Note the calibration history: P-0026 made the same peace bet in June at p=0.35 and resolved FALSE when oil rose instead. — The bear case against our own energy thesis got its best day yet — so we wrote it down as a scoreable bet instead of just noting it.
  For your money Fuel and heating costs are the most direct way a distant conflict reaches a household budget, and today's move points the right way. It is one day, from a high level, in a war that has not ended. This isn't a reason to make a big move: a cash buffer sized for bills that can jump is the general posture that works either way.

  What to watch Matters more if a passage arrangement is signed and shipping volumes normalise; less if the strike is rescheduled or the Omani channel stalls.
• #7 Equity concentration / breadth — CONFIRMED again, in the opposite direction. Last week the concern was that one stock (+$450bn in a session) could carry three indices up. Today two stocks took a national index down 5.12% the session after taking it up 17.91%. Concentration is direction-agnostic: it amplifies both. The flow split — institutions and foreigners selling ₩1.36tn combined, households buying ₩1.32tn — is the uncomfortable detail. — When a few companies decide what a whole market does, the market moves further in both directions than the news justifies.
  For your money Broad index funds are less broad than their name suggests when a handful of companies dominate them, so a 'diversified' holding can move on one sector's news. This isn't a reason to make a big move: knowing how concentrated your savings already are is worth more than reacting to any single day.

  What to watch Matters more if the same two-way violence repeats and spreads beyond Korea; less if daily ranges compress back to normal.
• #5 Sovereign / rates stress — WATCH, upgraded evidence. A confirmed joint US–Japan intervention is a materially stronger signal than the suspected unilateral one flagged on 30 July. Co-ordinated intervention by the US Treasury is rare. Against it: the 2s10s slope is a healthy +0.47pp, the US 10-year is 4.693% with no auction stress reported, and Japan's 10-year is 2.828%. Logged as P-0063 (dollar does not re-take 160 yen by 4 Sep, p=0.60). — The plumbing of the currency system needed official support last week — worth watching, but government bond markets themselves are behaving.
  For your money Currency stress abroad rarely touches a saver directly, but it shapes what foreign holdings are worth in your own money and it is one of the early places strain shows up. This isn't a reason to make a big move: it is a reason not to assume the current calm in bond markets is permanent.

  What to watch Matters more if the intervention has to be repeated, or if long-dated government bond yields start rising alongside it; less if the currency simply steadies.
• #1 AI-credit fragility — no new evidence today, and last week's disconfirmation stands. The Korean fall is an equity-positioning event, not a financing event: no widening in credit spreads (2.84pp), no reported funding stress. Broker target cuts are opinion, not cash flow. Resisting the temptation to score a chip selloff as credit fragility is the discipline here.
• #9 Labour deterioration — DISCONFIRMED this week. Claims at 197,000 with a four-week average 8.9% *below* the prior period, a Sahm gap of 0.07pp, and an ISM employment component back in expansion for the first time in nearly three years. The counterweight is June's soft +57,000 payroll and a 61.5% participation rate. Friday's July report is the test.
• #3 Crypto → AI/compute rotation — CONFIRMED, continuing. Bitcoin at $63,312 and ether at $1,857 again failed to participate in a broad risk rally, on a day equities rose almost 1% and a war scare receded.
