Crude oil spent Wednesday, October 7, jumping between $100 and $102 a barrel, and the international benchmark, Brent, was back above $101 for much of the session. Traders pointed to two sources of trouble: a run of attacks on ships in the Strait of Hormuz and Houthi strikes on airports in Saudi Arabia. Stocks gave back ground at the same time, with the Dow Jones Industrial Average closing at 51,179.87, down 341.41 points.
The question for anyone who drives, heats a home with oil or watches a fixed budget is whether crude at this level pulls gasoline prices up with it. Crude is the biggest single cost in a gallon of gas, so a benchmark that stays above $100 for days tends to show up at the pump, and the next few weekly pump-price readings will show whether this week’s move sticks.
UK officials counted at least nine Strait of Hormuz attacks in the first week of October, and the turn of the month on November 1 will show whether that pace held.

How Brent moved through the day
TheStreet’s market blog had Brent up 1.40 percent to $102 a barrel at 6:38 a.m. Eastern, with U.S. benchmark West Texas Intermediate up 0.76 percent to $90.12. Daniela Hathorn of Capital.com later described Brent as back above $101 after the Houthi attacks.
Yahoo Finance’s live blog shows the same pattern with timestamps. At 1:01 p.m. UTC it reported that Brent rose to trade back above $101 per barrel, and about 40 minutes later that it was moving toward $102. By the end of the blog, oil was described as staying near $100.
No official settlement price for Brent was published in either report, so $101 is a trading level, not a closing price. The November West Texas Intermediate contract was quoted at $88.96, up 68 cents, on Yahoo’s market panel.
The U.S. Energy Information Administration tracks a different measure, the daily Brent spot price, and its most recent published reading was $113.96 a barrel on September 29. Spot prices and futures contracts do not move in lockstep, so the gap between $113.96 and $101 is not a clean one-week drop. It does show that crude has been trading at a high level for weeks, not just on Wednesday.
Two attacks, two regions
Yahoo’s blog tied Wednesday’s oil move to “increased attacks in the Strait of Hormuz,” the narrow passage between Iran and Oman that carries a large share of the world’s seaborne crude. It added that UK officials had reported at least nine attacks in the waterway so far in October. The blog did not say who carried them out, and the attacker is not named here for that reason.
The second driver was farther south. Saudi Arabia’s airports in Jazan and Najran were targeted in two attacks on Monday evening, according to the Saudi aviation authority, as reported by TheStreet. The same report describes the Houthis as Yemen’s Iran-backed group and says fighting with Saudi Arabia has escalated. Yahoo’s blog said the airport attacks revived concerns about the wider Middle East conflict.
Neither report gave a figure for oil that was actually kept from the market. The price reaction reflects the risk to shipments and to Saudi infrastructure, not a confirmed drop in supply.
Rates and stocks moved the same day
Oil was not the only market under pressure. TheStreet reported the 10-year Treasury yield at 5.35 percent early Wednesday, its highest level since 2002, and the 30-year at 5.724 percent, a 24-year high. The S&P 500 closed at 7,801.77, down 17.16 points or 0.22 percent, and the Nasdaq Composite at 27,538.69.
TheStreet also carried a CNBC report in which Cox Automotive’s Jeremy Robb pointed to “diesel prices at record highs” as a reason used-vehicle prices could soften. That is a reminder that fuel costs reach households through more than the gas pump, including freight, heating oil and delivery charges on groceries.
What crude means for a gallon of gas
The Energy Information Administration says the largest component of the retail price of gasoline is the cost of crude oil, and that its share varies over time and across regions. Refining costs, distribution and taxes make up the rest. Because crude is the biggest piece, a move of several dollars a barrel can feed through to the pump, though the timing varies and retail prices usually lag the futures market.
A crude price that has fallen from the EIA’s $113.96 spot reading to near $100 gives some room for pump prices to ease, while fresh attacks in the Gulf and on Saudi airports push in the other direction. Which force wins depends on whether shipping through Hormuz is actually interrupted, and that has not been reported.
Tracking pump prices while crude swings
The Energy Information Administration publishes its breakdown of what goes into a gallon of gasoline, which is the quickest way to see how much of a pump price follows crude and how much does not. For a budget that depends on driving, the crude-driven slice is the one to watch.
Comparing the price at a regular station against a weekly average over three or four weeks gives a cleaner read than a single day, because a one-day move in Brent of a dollar or two often reverses. Heating oil customers and anyone with a delivery contract should check whether the price is fixed or tied to the market.
The next readings that matter are the EIA’s Brent spot series, which resumes with the data after September 29, and the monthly count of Hormuz incidents from UK officials. Wednesday’s price level was the story, but those two numbers will show whether it holds.
