Brent crude, the benchmark that prices most of the world’s traded oil, was changing hands at about $102 a barrel on Sunday 4 October. Two price trackers put it at $102.25 and $102.61. That is above the $100 mark and far above where the year began.
At the start of 2026 the picture was very different. According to a chronology of the 2026 oil market, Brent finished the first full week of January at $63.34. It ended that month at $70.69, with uncertainty about Iran cited as a driver.
A year of sharp swings
Weekly price records compiled by Statista show how far the market has moved since. Brent’s weekly opening price peaked at more than $111 in mid-May. It slid to the low $70s by the end of June, then climbed back to about $91 by 21 July. The Statista table runs only to late July, so it does not cover the rise since.
Convex Research’s data show Brent up about 6% over the past 30 days, from $96.35 to $102.25. It is up about 4.9% on the week. The same site described a 3.7% overnight jump in crude. I could not confirm from an independent news report what triggered that move, so the cause remains unclear here.
These price pages are automated feeds, and their numbers differ slightly. They are a snapshot, not an official settlement price. Markets open on Monday, and the figure will change.
Why a barrel price reaches your wallet
Brent feeds directly into fuel costs. It also affects European inflation and the cost of imports for energy-buying countries, according to Convex’s explainer. The same page links the oil price to the decisions of central banks such as the European Central Bank and the Bank of England.
For ordinary readers, the path is fairly direct. Petrol and diesel prices follow crude with a lag. Heating, freight and airfares follow too. When those costs stay high, inflation proves harder to bring down, and central banks have less room to cut interest rates. That affects mortgage and loan costs.
Convex’s page says the Iran tensions, risk around the Strait of Hormuz and OPEC+ supply discipline have been supporting prices this year. That is that site’s reading of the market rather than a finding from a government agency or an exchange. Readers should treat it as one view.
Stocks have not blinked, yet
Equity markets have so far absorbed the higher oil price. According to Trading Economics, the S&P 500 index, tracked through a contract for difference, stood near 7,715 on 5 October. That is down 0.09% on the previous session and up about 14.5% on a year earlier. Its record, 7,816.70, was set in August.
The site also noted that oil prices had declined at one point, helping support the bond market. That sits awkwardly with the weekly rise shown elsewhere, and it probably reflects different time windows. The data do not settle the question.
What to watch
- Whether Brent stays above $100 once trading resumes this week.
- Any news on US-Iran relations or shipping through the Strait of Hormuz.
- Whether OPEC+ changes its output plans.
- Upcoming inflation readings, which will show how much of the energy rise is feeding through.
A single day at $102 does not make a trend. But a barrel that cost about $63 in January and now costs over $100 is a large change. Households tend to feel it first at the pump, then in the shop.
