Oil prices moved sharply higher on Monday as uncertainty around the Strait of Hormuz came back into focus, putting supply risks firmly on traders’ radar.
Brent crude futures rose $3.98, or 3.82%, to $108.30 a barrel by 09:59 GMT, while WTI gained $3.52, or 3.81%, to $95.93. The move followed an earlier gain of more than 2%, showing how quickly crude markets can react when expectations around Middle East supply change.
For traders across the UAE and wider Gulf markets, the Strait of Hormuz remains a key market variable because of its importance to global energy flows.
U.S.-Iran Talks Put Oil Traders on Alert
The latest price move came as expectations for progress between Washington and Tehran weakened.
Iran has linked the reopening of the Strait to conditions including reduced U.S. military pressure, the lifting of restrictions on Iranian oil sales and a ceasefire. U.S. President Donald Trump rejected Iran’s proposal but has indicated that further negotiations could take place this week.
That leaves crude traders watching two possible scenarios.
If negotiations make progress and shipping through Hormuz returns closer to normal, additional crude supply could put downward pressure on prices. If talks break down, supply uncertainty could remain and keep a geopolitical premium in Brent and WTI.
For Gulf-based traders, that means headlines from Washington and Tehran could continue creating sharp intraday moves.
Hormuz Flows Are Recovering, But Supply Is Still Tight
The physical supply picture is showing some improvement, although it is far from normal.
Reuters reported that crude exports from key Middle Eastern producers increased to 12.8 million barrels per day in September, the highest level since the conflict began. Shipments through the Strait of Hormuz were expected to reach about 7.4 million barrels per day this month.
However, regional exports were still around 6 million barrels per day below February’s 18.8 million barrels per day, according to Kpler data cited by Reuters.
So, while some flows have recovered, the broader supply deficit has not disappeared.
The Strait of Hormuz previously carried around one-fifth of global crude oil and liquefied natural gas supplies. Any sustained reduction in shipping activity can therefore have a major impact on crude and refined-product markets.
Diesel Prices Add Another Concern
Oil traders are also keeping a close eye on diesel.
European and U.S. diesel prices have reached record levels as disruptions affecting Middle Eastern and Russian crude and refined-product exports tighten fuel supplies.
Reuters reported that Goldman Sachs estimated a U.S. diesel export ban could increase European wholesale diesel prices by around $3 a barrel for every week it remained in place.
For the wider market, that matters because sustained fuel inflation could feed into broader inflation expectations and influence interest-rate expectations.
Higher Oil Is Affecting Other Markets
The oil rally is not happening in isolation.
Reuters reported that global stocks fell on Monday as crude prices climbed, while the U.S. dollar moved toward a two-month high. The U.S. 30-year Treasury yield also rose to 5.517%, close to its highest level since 2004.
Gold moved lower. Spot gold fell around 3% to $4,156.45 an ounce by 08:14 GMT, reaching its lowest level in more than seven weeks.
The market relationship is straightforward for traders:
Higher oil → higher inflation risk → higher-rate expectations → stronger dollar and yields → pressure on gold and risk assets.
What Could Move Oil Next?
The next major catalyst is likely to be developments in U.S.-Iran negotiations and actual shipping activity through Hormuz.
A credible agreement that allows the Strait to reopen more normally could remove some of the geopolitical premium from crude. A breakdown in negotiations, renewed attacks or weaker physical oil flows could have the opposite effect.
For now, traders are balancing improving regional exports against the possibility that the wider supply deficit remains.
That makes geopolitical headlines particularly important for Brent and WTI traders.
Key Market Impact
| Market | Current Impact | Main Driver |
|---|---|---|
| Brent crude | Higher, above $108 | Hormuz uncertainty and supply risk |
| WTI crude | Higher, near $96 | Geopolitical risk and tighter supply expectations |
| U.S. dollar | Firmer | Safe-haven demand and higher-rate expectations |
| Gold | Lower | Higher oil-driven inflation and rate expectations |
| Global stocks | Under pressure | Higher energy costs and bond yields |
| Treasury yields | Higher | Inflation concerns and monetary-policy expectations |
The market moves above are based on the latest available Reuters reporting on September 28.
Trader Insight
The key question for crude traders is not simply whether the Strait of Hormuz is technically open.
The bigger question is whether oil can move through the route at volumes high enough to reduce the wider supply deficit.
Regional exports have recovered, but they remain below pre-conflict levels. If flows continue improving, crude could give back part of its geopolitical premium. If negotiations fail and physical flows weaken again, that premium could remain elevated.
UAE traders should therefore watch Brent prices, Hormuz shipping flows, refined-product prices, Treasury yields and the U.S. dollar together rather than looking at oil in isolation.
What to Watch Next
- U.S.-Iran negotiations: Any confirmed progress could quickly change oil’s risk premium.
- Strait of Hormuz shipping volumes: Sustained increases could ease supply concerns.
- Brent and WTI: Watch whether the latest price spike holds or reverses.
- Diesel prices: Continued strength could add to inflation concerns.
- U.S. Treasury yields and Fed expectations: Higher energy prices could support a higher-for-longer rate outlook.
- Gold and the U.S. dollar: Their reaction could show whether inflation and rate concerns are outweighing traditional geopolitical safe-haven demand.
