Oil near $99 and Canada's tariffs drag the Dow down 1.2%

Energy and trade did the damage. The Dow has shed 1.18% to 52,786.07, the widest US loss, with the S&P 500 down 0.58% at 7,673.52 and the Nasdaq Composite off just 0.32% at 26,421.41 as the closing prints land — a split that says the pain sat in cyclicals and defensives rather than in big tech.

Europe finished close to flat and hid a lot beneath: the DAX ended unchanged at 26,007.63, the CAC 40 and Euro Stoxx 50 both up 0.14%, the FTSE 100 down 0.10% at 10,811.66. Asia was the day's bright spot — the KOSPI closed 4.0% higher at 6,954.52 and the Nikkei 225 added 0.38%, though the Hang Seng ended 1.30% lower at 25,317.18 and the Shanghai Composite managed 0.27%.

The tape ran on crude. Brent has climbed 3.19% to $99.35 and WTI 3.06% to $94.28 after Saudi Arabia said its energy assets were attacked by Houthi forces, forcing temporary shutdowns at several facilities. An oil shock of that shape is an inflation problem before it is a growth problem, which is why US yields rose across the curve — the ten-year up 2.2 basis points to 4.806%, the five-year up 2.3 — and why the day was harder on rate-sensitive cyclicals than on megacap technology.

Running alongside it, Canada's retaliatory tariffs of 15% to 50% on roughly $20bn of US goods took effect today, covering steel, dairy, appliances, farm equipment and electronics. That is a direct hit to exactly the industrial and materials complex the Dow leans on, and the S&P/TSX fell 1.07% in sympathy.

Europe's weakness was company-specific rather than macro: Novartis dropped 10.89% to CHF111.80 after its myotonic dystrophy candidate del-desiran, the centrepiece of its Avidity Biosciences purchase, missed its primary endpoint in a Phase 3 study — a third pipeline setback inside a week. That single stock took the SMI down 1.55% and dragged health care to the bottom of the US sector table too.

This was risk-off in the cash market without any panic in the derivatives. The VIX closed up 2.75% at 15.72, historically subdued; rates volatility did more, with the MOVE index up 4.16% to 76.14, consistent with an oil-driven rethink of the Fed path. The safe-haven bid was notably absent — gold fell 0.60% to $4,403.40 and the dollar index eased 0.30% to 98.862, so this was not money running for cover, it was money repricing inflation.

Sector dispersion tells the story cleanly: energy (+1.11%) and utilities (+0.86%) up, health care (−2.52%), financials (−1.38%) and materials (−0.95%) down. PrimerIQ's own breadth calculations across our listed universe show 300 advancers against 442 decliners in the UK and a 0.90 advance-decline ratio in Europe — soft, but nowhere near washed out.

Nothing of consequence printed in the US today; the session's inputs were prices and policy, not data. The reference point behind the hawkish tone remains Friday's August payrolls, which showed a stronger-than-expected 162,000 jobs, and July CPI, the most recent reading, at 3.4% over twelve months.

The week's tests are all ahead. Producer prices are due before Thursday's opening bell, and August CPI lands on Friday 11 September at 08:30 ET — the release that will decide how seriously markets take the roughly even-money pricing of a Federal Reserve hike at next week's meeting. With crude up a third in a month, the energy pass-through in that print is the number that matters.

The after-close slate came in ahead of forecasts across the board. Casey's General Stores reported first-quarter EPS of $7.37 against a $6.60 consensus, an 11.7% beat; ServiceTitan posted $0.40 versus an expected $0.09 loss, and Braze $0.19 against a forecast $0.21 loss. GameStop matched at $0.27 as revenue fell year on year, but lifted its full-year adjusted EBITDA guidance to more than $650m from more than $600m, helped by gains on its eBay stake.
