Oil prices jumped sharply on Monday as uncertainty around the Strait of Hormuz returned to the market, putting global supply risk back in focus.
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 followed an earlier gain of more than 2%, showing how fast crude can move when traders start pricing in fresh supply concerns.
For traders in Nigeria, where oil remains a major part of the economy and global energy prices can have wider market implications, the latest move is worth watching closely.
U.S.-Iran Talks Keep Traders on Edge
The immediate trigger was the lack of progress between Washington and Tehran.
Iran has maintained 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 further negotiations could take place this week.
That leaves oil traders watching two possible directions.
If diplomacy improves, more crude could reach the market, putting pressure on prices. If talks break down, supply uncertainty could remain high and keep the geopolitical premium in oil elevated.
For traders, the market can move quickly when fresh headlines hit.
Oil Flows Are Improving, But the Supply Gap Remains
The latest shipping data give traders a mixed picture.
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 around 7.4 million barrels per day this month.
However, regional exports remained about 6 million barrels per day below February’s 18.8 million barrels per day, according to Kpler data cited by Reuters.
So, while supply flows have improved, they have not fully returned to previous levels.
The Strait of Hormuz is particularly important because it previously carried around one-fifth of global crude oil and liquefied natural gas supplies. Any sustained disruption can therefore have a major impact on oil and fuel markets.
Diesel Prices Add More Pressure
Traders are also watching diesel closely.
European and U.S. diesel prices have reached record levels as disruptions involving 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 push European wholesale diesel prices higher by around $3 a barrel for every week it remained in place.
That matters because higher fuel prices can feed into broader inflation, which can then influence expectations around interest rates.
Oil Is Also Moving the Dollar, Gold and Stocks
The crude rally is affecting other markets as well.
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 in the other direction. Spot gold fell around 3% to $4,156.45 an ounce by 08:14 GMT, its lowest level in more than seven weeks.
The broader market chain is:
Higher oil → stronger inflation concerns → higher-rate expectations → stronger dollar and yields → pressure on gold and risk assets.
For Nigerian traders following forex, commodities and global markets, this cross-market relationship can be important when oil makes a large move.
What Could Move Oil Next?
The next major catalyst will likely be developments in U.S.-Iran negotiations and evidence of actual shipping flows through Hormuz.
A credible agreement could allow the Strait to operate more normally and remove part of the geopolitical premium from crude.
On the other hand, another breakdown in negotiations, renewed attacks or falling physical oil flows could keep supply concerns elevated.
For now, the market is balancing improving exports against the possibility that the broader supply deficit remains.
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 issue for oil traders is not just whether the Strait of Hormuz is open.
What matters is whether crude can actually move through the route in volumes large enough to reduce the wider supply deficit.
Regional exports have recovered, but they remain below pre-conflict levels. If flows continue improving, oil could give back some of its geopolitical premium. If negotiations fail and physical flows weaken again, supply risk could remain a major price driver.
For Nigerian traders, it is worth watching Brent, WTI, Hormuz shipping flows, diesel prices, U.S. Treasury yields and the dollar together. These markets can give a clearer picture of where the next move in crude may be coming from.
What to Watch Next
- U.S.-Iran negotiations: Fresh headlines could trigger another sharp move in crude.
- Hormuz shipping volumes: A sustained recovery could ease supply concerns.
- Brent and WTI: Watch whether the latest rally holds or starts to reverse.
- Diesel prices: Further increases could add to inflation concerns.
- Treasury yields and Fed expectations: Higher energy prices could strengthen the higher-for-longer rate outlook.
- Gold and the U.S. dollar: Their reaction could show whether inflation and interest-rate concerns are dominating market sentiment.
