Oil prices jumped sharply on Monday as uncertainty around the Strait of Hormuz returned to the spotlight, bringing supply concerns back into focus for crude traders.
Brent crude futures rose $3.98, or 3.82%, to $108.30 a barrel by 09:59 GMT. WTI gained $3.52, or 3.81%, to $95.93. The move came after an earlier rise of more than 2%, showing just how quickly oil can react when the market starts pricing in renewed supply risk.
For traders watching the Gulf region, the situation around Hormuz is especially important because shipping conditions through the Strait can have a direct impact on global energy markets.
U.S.-Iran Talks Remain a Key Oil Driver
The latest jump came as expectations for progress between Washington and Tehran weakened.
Iran has set conditions for reopening the Strait, 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 more talks could take place this week.
So, traders are now watching both sides of the story.
If talks move forward, improved oil flows could take some pressure off prices. If negotiations stall again, supply concerns could stay in place and keep the risk premium in crude elevated.
For traders in Oman and the wider Gulf, this means a single diplomatic headline could still cause a big move in oil.
Oil Flows Are Improving, But Not Back to Normal
There is some positive news on physical supply, but the numbers still show a sizeable gap.
Reuters reported that crude exports from key Middle Eastern producers rose 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 around 7.4 million barrels per day this month.
Even so, regional exports were still around 6 million barrels per day below February’s 18.8 million barrels per day, based on Kpler data cited by Reuters.
In simple terms, flows are improving, but the market is still dealing with a supply shortfall.
The Strait of Hormuz previously carried around one-fifth of global crude oil and liquefied natural gas supplies. Any major disruption can therefore quickly affect crude, fuel and energy markets.
Diesel Is Another Market to Watch
Crude is not the only part of the energy market under pressure.
European and U.S. diesel prices have reached record levels as disruptions to 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 lift European wholesale diesel prices by about $3 a barrel for every week it remained in place.
If fuel prices stay elevated, the impact could spread beyond energy markets through higher inflation expectations.
Oil Rally Puts Pressure on Other Markets
The jump in crude is also being felt across financial markets.
Reuters reported that global stocks fell on Monday as oil prices climbed, while the U.S. dollar moved toward a two-month high. The U.S. 30-year Treasury yield rose to 5.517%, close to its highest level since 2004.
Gold moved lower, with spot gold falling around 3% to $4,156.45 an ounce by 08:14 GMT, its lowest level in more than seven weeks.
For traders, the relationship is worth keeping in mind:
Higher oil → more inflation pressure → higher-rate expectations → stronger dollar and yields → pressure on gold and risk assets.
What Could Move Oil Next?
The next big driver is likely to be U.S.-Iran negotiations and actual shipping volumes through the Strait of Hormuz.
A credible agreement that allows the Strait to operate more normally could reduce some of the geopolitical premium in crude. A further breakdown in talks, renewed attacks or weaker physical flows could keep supply concerns elevated.
For now, the market is weighing improving exports against the possibility that the wider supply deficit continues.
That means oil traders need to keep an eye on both diplomatic headlines and physical shipping data.
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
For crude traders, the main issue is not simply whether Hormuz is open.
What really matters is whether oil can move through the Strait in enough volume to ease the wider supply shortage.
Regional exports have improved, but they remain below pre-conflict levels. If shipping flows keep recovering, some of the geopolitical premium could come out of crude. If negotiations fail and physical flows fall again, oil could remain sensitive to supply headlines.
For Oman traders, it makes sense to watch Brent and WTI alongside Hormuz shipping flows, diesel prices, Treasury yields and the U.S. dollar.
What to Watch Next
- U.S.-Iran negotiations: New developments could quickly change crude’s risk premium.
- Hormuz shipping volumes: A sustained recovery could ease supply concerns.
- Brent and WTI: Watch whether the latest jump holds.
- Diesel prices: Continued strength could increase inflation pressure.
- Treasury yields and Fed expectations: Higher energy prices could support expectations for higher rates for longer.
- Gold and the U.S. dollar: Their reaction could reveal how strongly inflation and rate concerns are affecting markets.
