Renewed U.S.–Iran Clash in the Strait of Hormuz Sends Oil Prices Higher
7/13/2026, 10:02:25 PM
Core Event
In early July 2026 the United States and Iran exchanged strikes after Iran’s Islamic Revolutionary Guard Corps attacked the Cyprus-flagged container ship MV GFS Galaxy in the Strait of Hormuz. The U.S. Central Command (CENTCOM) reported “dozens of strikes” on Iranian targets, while Iran responded with missile and drone attacks on U.S. facilities in Kuwait, Bahrain, Jordan and Oman. The fighting halted the limited traffic that had resumed after the June 17 interim memorandum of understanding (MoU). Brent crude rose 3-4 % to roughly $79 per barrel, and West Texas Intermediate climbed to about $74 per barrel, marking the highest levels since the cease-fire was signed.
Background & Context
The conflict began in late February 2026 when the United States and Israel launched strikes on Iranian facilities. An interim MoU signed on June 17 2026 temporarily reopened the strait, allowing oil flows to rebound to about two-thirds of pre-war levels. Prior to the February attacks, roughly 130 vessels crossed the Hormuz corridor each day, carrying about 20 % of global oil and gas supplies. By early July, maritime-tracking data showed only six to nine vessels transiting daily, a fraction of normal traffic.
Data & Statistics
- Brent futures for September delivery: $79.17 / bbl (03:00 GMT, 12 July).
- U.S. crude (WTI): $74.26 / bbl (same time).
- Traffic: 6-9 vessels per day vs. 130 pre-war; Windward tracked nine ships on 12 July.
- Strategic Petroleum Reserve (SPR): ~300 million bbl remaining, down from 415 million bbl at the war’s start; 172 million bbl authorized for release over several months.
- Cushing, Oklahoma crude inventory: 19.6 million bbl, below the 20 million bbl safety threshold.
- Global refining capacity offline: ~7 million bpd, according to Marshall Adkins (Raymond James).
Why It Matters / Impact
Higher crude prices translate into higher gasoline, diesel and jet-fuel costs, pressuring inflation and consumer spending. AAA reported the U.S. regular-unleaded pump price at $3.88 per gallon on 10 July, up from $3.15 a year earlier. Analysts estimate a $5 per-barrel geopolitical risk premium will remain baked into prices for the foreseeable future. The price surge also complicates President Donald Trump’s effort to keep fuel costs low ahead of the November midterm elections.
Official Statements & Responses
- President Donald Trump declared the interim MoU “over” and warned of a possible naval blockade.
- CENTCOM reiterated that “Iran does not control it” and pledged to keep the strait open for lawful navigation.
- Iranian Persian Gulf Strait Authority warned that vessels using “unauthorized routes” would bear responsibility for any consequences.
- Vice President JD Vance said the MoU should be used to “refill the world’s oil economy, to refill some stocks.”
- U.S. Energy Information Administration projected global crude production will near pre-conflict levels by the end of 2026, assuming continued output growth.
Criticism & Opposition
Energy analysts such as Marshall Adkins argue that Iran will demand a tolling system, likely limiting traffic to half of normal volumes. Dan Pickering (Pickering Energy Partners) cautioned that “the regime is not very weakened,” suggesting that Iranian pressure tactics will persist. Jim Wicklund (PPHB) warned that the Hormuz disruption represents “the greatest energy supply shock in modern history,” but doubted it will trigger a permanent shift away from oil.
Conflicting Reports & Gaps
- Brent price figures vary across sources ($78.96, $79.17, $81.92).
- Daily vessel counts differ (six, nine, or “around 130” pre-war).
- SPR inventory is reported as “more than 300 million bbl” and “the lowest level since 1983,” without a precise figure.
- The timeline for replenishing Cushing inventories remains unclear.
Verbatim Quotes
- “Iran does not control the strait.” — U.S. Central Command
- “I think what the president has told us to do is use this MoU (memorandum of understanding) to sort of refill the world's oil economy, to refill some stocks, and then to see where the hand is,” — Vice President JD Vance
- “The southern route creates a route they can't toll or control.” — Rear Adm. Mark Montgomery
- “These attacks on shipping to me aren't random. They're strategy.” — Vice Adm. Kevin Donegan
What’s Next
The Trump administration has authorized the release of 172 million bbl from the SPR over the coming months, but no schedule for replenishment has been announced. The International Energy Agency warns that any prolonged disruption of Hormuz traffic could reverse recent supply gains and push markets back toward a deficit later in the year.
