Oil Surges as Iran Fighting Resumes, Gas Nears $4.03 Record

Fighting Reignites, Markets React Fast

Energy markets jolted awake heading into Labor Day weekend after the United States and Iran traded attacks for the first time in roughly a month, ending a fragile pause that had briefly calmed crude markets 111. U.S. forces struck Iranian rocket launchers on Larak Island inside the Strait of Hormuz, and Iran responded with missile attacks on American bases in Jordan that were reportedly intercepted 91016. Trump also posted footage claiming Iran's Kharg Island energy hub had been "blown to smithereens," though Reuters found no evidence of such a strike and a U.S. official denied targeting the island, with the video appearing to be AI-generated 11.

The renewed exchange broke a monthlong lull that began after Trump announced a strike "pause" on Aug. 1, and it arrived just as diplomatic efforts by mediators including Qatar and Oman had failed to gain traction on reopening safe shipping through Hormuz 912.

Crude Jumps, Gasoline Lags Behind

The most immediate reaction showed up in crude. Brent futures rose 3.4% to $91.09 a barrel and U.S. West Texas Intermediate climbed to $86.22, both up roughly $3 on the day 91011. The rally extended into Tuesday, with Brent adding another $1.05 to $91.54 and WTI gaining $1.27 to $87.03, according to Reuters, after Monday settlements finished 2.7% and 2.8% higher respectively 12. The Associated Press likewise tracked Brent near $91.23 and WTI around $86.62 as Asian markets absorbed the news 16.

Gasoline, by contrast, barely budged in the first 24 hours. AAA's national average sat at about $4.08 a gallon on Monday, up just two-tenths of a cent, while diesel held near $5.60 91013. In Michigan, prices were reported flat week-over-week at $4.15 a gallon, with Jackson, Ann Arbor and Lansing posting the state's highest local averages 111. That lag is normal: retail fuel prices typically trail crude moves by several days rather than adjusting instantly, and the national average was already sitting 37% above where it stood when the war began 10.

Even so, the starting point going into the holiday was already historic. AAA and GasBuddy both flagged August as on pace to be the most expensive August for gasoline on record, surpassing even 2022's summer spike 461113. GasBuddy's official Labor Day forecast put the national average at $4.03 a gallon, 87 cents above last year's $3.16 and higher than the prior nominal record of $3.83 set in 2012 141517. A full 15-gallon fill-up now runs motorists roughly $62 11.

Why the Strait of Hormuz Keeps Driving Prices

Analysts trace the volatility to fears that renewed hostilities could further choke shipping through the Strait of Hormuz, the narrow waterway between Iran and Oman that historically carries about one-fifth of global oil shipments and a similar share of LNG trade 101218. Visible vessel traffic through the strait had fallen to about five ships a day, well below the ten-day average of roughly 14, and none of those five was a liquid tanker, according to Kpler data cited by Reuters 12. Satellite tracking suggested oil flow through Hormuz of around 6 million barrels a day, still well under pre-conflict levels 12.

Tim Waterer of KCM Trade said the renewed strikes reintroduced the possibility of Iranian retaliation against Gulf energy infrastructure, a risk now embedded in crude's firmer tone 12. PVM Oil Associates' Tamas Varga warned that supply risk would persist and inventories would keep draining as the conflict reshapes the region's security landscape 9. Underscoring the fragility, the UK Maritime Trade Operations agency reported a tanker struck by projectiles while leaving the strait, and Goldman Sachs noted that strikes on refineries in both the Middle East and Russia have squeezed already-tight global refining capacity, pushing refined-product margins to record highs 912.

That refining squeeze helps explain why crude and pump prices have become somewhat disconnected. GasBuddy said the widening gap has pushed refining margins, or "crack spreads," to record levels, a dynamic that could keep gasoline and diesel elevated even if crude eases, and one that may push diesel to fresh records in the weeks ahead 17.

Strategic Reserves Under Strain, Venezuela Deal No Quick Fix

Adding to the unease, the U.S. Strategic Petroleum Reserve has fallen to its lowest level since 1982, dropping about 3.1 million barrels in the latest week to 286.6 million barrels 91012. That leaves Washington with less cushion for a large emergency release if disruptions worsen.

Trump has pointed to a newly announced deal with Venezuela, claiming the U.S. secured majority control of more than 65 billion barrels of reserves and vowing to use the arrangement to refill the SPR and eventually lower gas prices 91011. But GasBuddy's Patrick De Haan cautioned that any benefit from expanded Venezuelan output would take years to materialize and would not move near-term prices, which instead hinge on U.S.-Iran developments and Ukrainian strikes on Russian refineries 11.

Natural Gas Tells a Different Story at Home

While oil and gasoline headlines dominated, natural gas markets split sharply along geographic lines. Europe and Asia, which depend on LNG cargoes routed through Hormuz, have faced real strain: gas storage in Europe is running unusually low for the season, with some forecasts warning prices could top 100 euros this winter if flows stay disrupted 5. Earlier in the conflict, Dutch TTF futures jumped roughly 40% and Asian JKM LNG benchmarks rose nearly 39% in a single session, while U.S. natural gas futures moved a comparatively modest 3.5% 18.

The U.S. Energy Information Administration has consistently said domestic Henry Hub prices should remain relatively insulated because American supply relies on domestic production and pipelines rather than imported Gulf LNG 19. Recent data support that: Henry Hub spot prices sat at $2.70 per million BTU on Aug. 25, down from $2.94 a week earlier, according to Federal Reserve data 20. Some commentary has cast natural gas as undergoing a global "seismic shift" with implications for central bank policy, but that framing applies far more to European and Asian consumers than to U.S. households 7. Separately, structural change in U.S. power markets — with natural gas capacity in interconnection queues nearly tripling since 2024 — reflects longer-term utility planning rather than the current geopolitical shock 3.

What Comes Next

Seasonal patterns typically favor lower gasoline prices after Labor Day: demand usually declines after its mid-July peak, and much of the country shifts to cheaper winter-blend fuel after Sept. 15 1417. Consumer-price trackers have also noted that many everyday costs eased in July even as gasoline and select food items stayed near records 28.

Whether that seasonal relief materializes this year depends heavily on whether the Iran conflict stays contained or escalates further. Reuters-polled analysts expect oil to remain above $80 a barrel through 2026 given the persistence of shipping disruptions 12. For now, the clearest takeaway is that crude has reacted immediately and sharply, gasoline is following with its usual lag but from an already record-setting base, and natural gas remains a story primarily affecting Europe and Asia rather than the average American utility bill.
