Saudi Arabia's East-West pipeline, a land route that bypasses the Strait of Hormuz, has been shut since attacks last week. West Texas Intermediate was at $105.99 a barrel at 4:13 p.m. ET, up 4.5%, and the 10-year Treasury yield traded as high as 5.04%. The S&P 500 fell 34 points, or 0.5%, to 7,585.51.
The session split between what higher crude pays and what higher fuel and borrowing costs take. Fewer than one in five U.S.-listed ETFs finished higher: 1,000 rose, 4,329 fell, of 5,444 priced.

The VIX closed at 17.28, up 1.1%, a modest print next to that breadth.
The State Street S&P 500 fund SPY fell 0.5% on volume 1.13 times its 20-session median. The Nasdaq-100 fund QQQ fell 0.7% on some of its lightest volume in 20 sessions. The Russell 2000 fund IWM dropped 1.0%, extending a five-session decline of 3.2%.
Crude pays producers, not pipelines
The oil fund USO closed 3.3% higher at $161.86, less than 1% below its 52-week high, and is up 10.9% over five sessions and 28% over one month.

The energy sector fund XLE gained 2.2%, a fraction below its 52-week high. Exxon Mobil, 20.2% of the fund, rose 2.5% and contributed 0.52 percentage points; Chevron added 0.40 points. An exploration-and-production fund, XOP, rose 3.2%. All six 2x/3x long energy funds finished higher, a median 3.8%.
The same oil move did not lift the pipes. A midstream fund, AMLP, fell 0.3%. Inside XLE, Oneok lost 2.3%; Kinder Morgan, Targa Resources, and Williams each finished lower. An airline fund, JETS, fell 1.1%. A retail fund, XRT, dropped 2.7%. Consumer discretionary lost 1.8%, with the decline concentrated at the top: Amazon is 24.6% of XLY and accounted for 0.50 percentage points of that fund's loss.
Producers and the crude fund captured Tuesday. Semiconductors only paused, and bitcoin and high yield did not.
Microsoft and Amazon did the damage chips did not
Monday's semiconductor selloff stopped. That slide followed a Saturday essay from Anthropic chief executive Dario Amodei arguing that AI labs should slow how fast they improve model capabilities. The iShares semiconductor fund SOXX rose 0.3% after falling 5.6% on Monday; the VanEck semiconductor fund SMH rose 0.1%. Nvidia gained 0.6%, Advanced Micro Devices 2.2%. Over five sessions SOXX is still down 5.6%. That is a pause, not a repair.
The S&P 500 tracker still fell because the rest of large-cap technology did not join them. Microsoft, 5.7% of SPY, lost 1.6% and subtracted 0.09 percentage points; Amazon lost 2.0% and subtracted 0.08 points. Nvidia's gain added 0.04 points. In QQQ, Netflix's 3.0% drop and Broadcom's 1.6% decline sat beside those same hits. A software-stock fund, IGV, fell 1.0% one session after rising 5.0%.
The Dow Jones Industrial Average fell 328 points, or 0.6%, to 52,093.11. Goldman Sachs, 11.2% of the Dow fund DIA by price weight, lost 1.2% and subtracted 0.13 percentage points, the largest single drag. Chevron's 2.6% gain was not enough to offset it.
Credit and utilities leak with the 10-year
Long Treasurys kept leaking. The long-term Treasury fund TLT fell 0.3%, a five-session drop of 1.8%, and closed near a 52-week low. The dollar fund UUP rose 0.2% for a fourth straight session; the U.S. Dollar Index was at 99.38, up 0.3%.
Investment-grade credit barely moved. The investment-grade fund LQD was unchanged, though that still marked a fifth consecutive down session. High yield did not get the same pass: HYG fell 0.2% for a seventh straight session, a streak that began September 4, and closed at $78.38, matching its 52-week low. Utilities, which often trade like long duration, fell with the bonds. The utilities sector fund XLU lost 1.2% for a fifth down session and closed a few cents from its 52-week low.
Senate blocks the Clarity Act as every spot crypto fund falls
At 2:15 p.m. ET the Senate refused to take up the Clarity Act, a market-structure bill that had passed the House 294-134 and would have split oversight of digital assets between the Commodity Futures Trading Commission and the Securities and Exchange Commission. Cloture needed 60 votes. The refusal leaves that split where it was this morning: classification still runs through agency actions and court rulings, not a line Congress drew.
Bitcoin was at $75,819 around the equity close, down 3.0%. Ether was down 4.5%. Every one of 69 U.S.-listed crypto spot funds closed lower, a median 4.9%. The iShares Bitcoin Trust IBIT fell 3.6%. Coinbase lost 10.1%. A fund built to deliver twice Coinbase's daily move, CONL, fell 20.0% on $188 million of turnover. Circle Internet Group dropped 11.4%; XRP fell 10.3%.
The Fed walks into $106 oil
The Federal Reserve's two-day meeting ends Wednesday with a rate decision and a fresh set of economic projections. The federal funds target range is 3.50% to 3.75%. After Friday's inflation report, CME FedWatch put the probability of a quarter-point hike at 85%, up from 72% the day before and roughly 50% a month earlier. The New York Fed's Empire State manufacturing index came in at 7.6, down from 20.6 in August, still positive and below the 14.1 forecast.
A quarter-point increase would raise the policy rate in the same week crude is both the inflation in the fuel bill and the paycheck in energy funds sitting a fraction below a 52-week high. High-yield closed at a 52-week low. The pipeline is still shut.
