9.10.2026 US Stock Market Daily | Oil Breaks $100, Market Starts Pricing in a Rate Hike

WTI crude surged 8.46% in a single day to $104.18, while all three major indices closed lower: S&P 500 at 7,591.70, down 0.58%; Nasdaq at 26,081.72, down 0.65%; Dow at 52,064.10, down 0.60%. The 10-year Treasury yield hit 4.94%, VIX jumped 8.38% to 17.84, and the Dollar Index rose 0.32% to 99.09. SPY has now fallen for three straight days. The WSJ headline that day put it bluntly: oil climbing, bond yields jumping.

The spark behind oil’s leap came from the Middle East. Trump said Iran has some missiles, most of which have already been destroyed, while China stated its opposition to certain countries pushing the UN Security Council to reinstate sanctions on Iran. What’s interesting is the pricing on prediction markets: on Polymarket, “US invades Iran before 2027” sits at just 16%, and “Strait of Hormuz returns to normal transit by year-end” is also at 16%. These two 16% figures together form an awkward combination — traders don’t believe the war will fully escalate, nor do they believe the shipping lane will recover quickly. For oil prices, this is precisely the most uncomfortable state to be in: not a one-time spike from a full war-risk premium, but a supply bottleneck being slowly stretched out and priced into the curve bit by bit. Today’s 8% jump looks more like the latter.

What really deserves attention is where oil connects to interest rates. According to Trading Economics data, July inflation came in at 3.40%, versus a prior reading of 3.50%, with the federal funds rate at 3.75%. Inflation had been on a downward path, and oil just kicked it back up. That’s why the four Polymarket contracts on the September meeting delivered today’s sharpest numbers: 25bp hike at 64%, no change at 36%, 25bp cut at 0%, and a cut of 50bp or more at 0%. Both the 25bp-hike and no-change contracts saw 24-hour trading volume above $1 million — not noise from a thin, quiet order book. With cut probability pinned at 0%, the market has essentially taken “easing” off the table entirely; the remaining debate is whether to hike, not whether to cut.

The bond market is sending the same directional signal, and not just in the US. The 2-year Treasury yield jumped as much as 15 basis points at one point, while Australia’s 3-year government bond yield rose 16.59 basis points, hitting a fresh high since May 2011 at 5.0170% early in Sydney trading. The short end is moving more sharply than the long end — that’s the shape of a monetary policy path being repriced, not a story about fiscal or term premiums. Treasury Secretary Bessent spent today downplaying concerns about Treasury buybacks, saying the bond market is in strong shape, and specifically clarified his earlier “I’m the house” comment: he said he wasn’t challenging anyone to come find him, but rather trying to convey that he has superior information and is working to give the market a framework so people don’t panic. Some observers noted that intervening in the Treasury market seems to run counter to Warsh’s stated position. The fact that the Treasury Secretary needs to publicly explain his own role in the bond market is itself more noteworthy than what he actually said.

One easily overlooked divergence: silver futures fell 3.41% to $66.31. If today were a clean inflation trade, precious metals would have no reason to part ways with crude. Oil up, silver down looks more like a supply-side price shock layered on rising real rates, rather than a broad repricing of inflation expectations. This distinction matters for positioning: the former hurts transportation, chemicals, and airlines on the cost side, while only the latter would truly force a systematic valuation reset on duration assets. Right now, the market appears to be pricing the former — the fact that the Nasdaq only fell 0.65% today supports this reading.

At the single-stock level, ARK’s portfolio rebalancing is the most notable move. ARKK slashed GOOGL from 74,781 shares to 1,882 shares, a 97.5% cut, leaving the position at just 0.01% — essentially a full exit — while on the same day adding to META, from 153,743 shares to 191,849 shares, up 24.8%, bringing its weight to 1.92%. ARKW made the identical move: GOOGL down 95.4%, META up 5.9%. Cutting a holding down to a mere remnant in a single day isn’t rebalancing — it’s a changing of the guard. META closed at $653.69 today, with an RSI already at 77.3, sitting firmly in overbought territory; adding to a position at this level carries strong conviction but comes at a steep price. By contrast, AAPL’s RSI is only 42.5 and it has fallen for three straight days, while AMZN sits at 51.3 and has also fallen for three straight days — the divergence within the Magnificent Seven is widening.

Two things to watch going forward. First, whether WTI can hold above $104 — if it falls back below $100, today’s valuation hit will turn out to be just a blip. Second, whether the 2-year yield keeps climbing — if it continues higher, the priced-in probability of a September hike will keep rising above 64%, and the first names to break down at that point will be the most expensively valued, latest-to-deliver-earnings names, not necessarily today’s biggest losers. If oil pulls back but short-end yields don’t follow it down, that would signal the market has stopped worrying about oil and started worrying about something else.
