Crude oil is closing out July with its biggest monthly surge since March, and the reason is the same one that’s been driving headlines all month: the ongoing war between the U.S. and Iran and the fight over who controls the Strait of Hormuz.
Quick Answer
U.S. crude benchmark West Texas Intermediate is holding near $84 a barrel after swinging in a range of more than $8 this week, putting oil on pace for its biggest monthly surge since March — up roughly 21% in July alone. Brent crude, the international benchmark, has settled around $89 a barrel. The rally has been driven by escalating U.S.-Iran military conflict, a stalled standoff over the Strait of Hormuz, and fresh threats from Houthi forces to blockade Red Sea shipping routes, even as prices ticked lower Thursday in a modest pullback.
Key Takeaways
- Oil is on track for its biggest monthly gain since March, with WTI up about 21% in July.
- WTI is holding near $84 a barrel; Brent settled around $89.
- Crude inventories posted their largest weekly draw since mid-June, a sign of tightening supply.
- Houthi forces have threatened to blockade Red Sea shipping routes, adding a second flashpoint alongside the Strait of Hormuz.
- Despite the escalating conflict, oil prices actually dipped Thursday in a "sell the news" pullback after the sharpest gains.
- Shell posted its best quarterly profit in four years, with the company crediting higher oil and gas prices tied to the war.
Why Oil Is Having Its Best Month Since March
The core story hasn’t changed in weeks: the Strait of Hormuz, through which roughly a fifth of the world’s oil supply passes, remains a flashpoint in the U.S.-Iran conflict. Iran has continued to insist on controlling passage through the waterway, and renewed military action this week reversed what had briefly looked like a cooling-off period. Prices eased in mid-July as diplomatic contacts around Hormuz appeared to make progress, then rebounded sharply within 48 hours as fresh fighting revived fears of a supply disruption.
That round trip is exactly what’s pushed oil to its steepest monthly climb since March, when a similar escalation drove prices up by roughly half over the course of the month. This time the gain is smaller in percentage terms, but it reflects the same underlying dynamic: markets pricing in real risk to one of the world’s most important shipping corridors.
A Second Flashpoint: The Red Sea
Adding to the pressure, Houthi forces in Yemen have threatened to blockade shipping through the Red Sea, which would compound the disruption already threatened at Hormuz. Together, the two chokepoints account for a significant share of global oil transit, and simultaneous threats to both routes have made traders more cautious about assuming any near-term return to normal shipping patterns.
Why Prices Dipped Even as the War Escalates
In something of a contradiction, oil prices actually eased Thursday even as fighting between the U.S. and Iran continued. That kind of pullback after a sharp run-up is common in commodity markets — once a risk is largely priced in, further bad news doesn’t always push prices higher, especially if traders see any signal, however small, that supply routes are still functioning. Reports that tankers continued transiting parts of the affected waterways despite the conflict likely tempered Thursday’s move.
Who’s Feeling the Impact
The rally hasn’t been bad news for everyone. Shell posted its best quarterly profit in four years, with the company pointing directly to the war-driven rise in oil and gas prices as a key factor. For energy companies with exposure to crude production, a sustained rally like this one flows straight to the bottom line, even as it raises costs elsewhere in the economy, from fuel prices to transportation and shipping.
What to Watch Next
With both the Strait of Hormuz and Red Sea shipping routes now in play, oil markets are likely to stay volatile through the end of the summer. Key things to watch: whether the U.S. and Iran show any signs of de-escalation, how the Houthi blockade threat develops, and upcoming inventory data that will show whether the recent supply draw continues.
FAQ
Why is oil having its biggest month since March?
The rally is being driven by escalating conflict between the U.S. and Iran, centered on control of the Strait of Hormuz, along with a large weekly draw in crude inventories that signals tightening supply.
Why did oil prices fall even though the war is getting worse?
Markets often price in geopolitical risk quickly, and once a risk is reflected in prices, further escalation doesn’t always push prices higher — particularly if there are signs, like continued tanker traffic, that supply isn’t yet meaningfully disrupted.
What is the Strait of Hormuz and why does it matter for oil prices?
The Strait of Hormuz is a narrow waterway between Iran and the Arabian Peninsula through which roughly a fifth of the world’s oil supply passes. Any disruption to shipping through it tends to move global oil prices sharply.
