$100 Oil, $6 Diesel, and NO to Banning Exports

September 21, 2026

Recorded: September 20, 2026

In episode 165 of the PetroNerds Podcast, Trisha Curtis, CEO of PetroNerds and host of the PetroNerds podcast, examines $100 barrel oil, diesel above $6 a gallon, and why banning U.S. diesel exports will not work. She connects the Federal Reserve’s rate increase with persistent energy inflation, explains the refining economics behind her opposition to export restrictions, and analyzes China’s renewed crude purchasing and the threats to Saudi Arabia’s Yanbu East–West pipeline. The episode explores how global disruptions reach American consumers—and why continued production, refining, and trade are essential to energy security.

Key Takeaways

$100 oil and $6+ diesel could keep inflationary pressure elevated.
Banning U.S. diesel exports could backfire.
U.S. energy security depends on production, refining, and global trade working together.
China’s renewed crude buying deserves close attention.
Global disruptions can raise U.S. prices even when America has adequate supply.

Trisha begins with the relationship between energy prices, inflation, and interest rates. She questions how effectively the Federal Reserve can address an inflation problem driven partly by oil-market disruptions and explains why higher borrowing costs could slow other parts of the economy without resolving the underlying energy constraints. Her concern is not simply that oil has reached $100 a barrel. It is the persistence of elevated oil, gasoline, and diesel prices, combined with expensive mortgages, that could increasingly weigh on consumers and economic activity. She is not calling for a recession, but she explains why her assessment of the economic risks has evolved as the conflict has continued.

Diesel is central to that discussion. Trisha looks beyond the cost of filling a pickup truck to its role in freight, rail transportation, construction, agriculture, and heating. She discusses the gasoline and diesel demand figures she is watching and the potential for sustained diesel-price increases to work their way through the wider economy. The question is both how much consumers are paying today and how long businesses can absorb higher fuel costs before passing them along.

The core of the episode is why banning diesel exports will not work. She walks listeners through the basic mechanics of refining: a barrel of crude produces multiple products, not a single fuel that policymakers can isolate without consequences. Different crude qualities and refinery configurations affect the product mix, but gasoline, diesel, and jet fuel remain connected through the economics of processing the barrel. Restricting diesel exports could weaken refining margins and reduce the incentive to process crude, undermining fuel supply rather than delivering price relief.

Trisha discusses U.S. commercial petroleum inventories separately from Strategic Petroleum Reserve drawdowns and credits the refining sector’s response with helping maintain supplies during the conflict. She also explains why U.S. crude imports and exports are not contradictory: the country produces light, sweet crude while sophisticated Gulf Coast refineries are equipped to process heavier barrels, including Canadian oil-sands crude. Preserving trade flows supports the production and refining system rather than detracting from American energy security.

Natural gas provides another example of the importance of market access. Trisha contrasts low Henry Hub prices with much higher European natural-gas prices and discusses competition between Europe and Asia for LNG. Continued LNG exports are important both for sustaining and growing U.S. natural gas production and for maintaining America’s credibility as an international supplier. She warns against allowing the diesel-export debate to become a broader justification for restricting crude oil, refined products, or LNG (liquefied natural gas).

The conversation then turns to China. Building on the previous PetroNerds episode with Jason Isaac, Trisha distinguishes crude imports, stockpiling, and end-user consumption. She examines the increase in Chinese crude purchases and challenges the explanation that attractive refining margins alone account for China’s return to the market. China’s inventory position, purchasing decisions, and management of refined-product exports provide geopolitical leverage.

Saudi Arabia’s East–West pipeline and the Red Sea export route form the episode’s final major focus. Trisha explains why the route to Yanbu has been an essential outlet during the conflict and examines the reported attacks, including drone activity originating in Iraq. She distinguishes damage to pumping infrastructure from damage to the underground pipeline itself and discusses the importance of repairs, restored flows, port logistics, storage, and tanker availability. She also considers the implications of disrupted Saudi crude deliveries to Europe.

Trisha closes by bringing the discussion back to the global refined-product market, including attacks on Russian refineries and Russian diesel-export restrictions. American consumers are exposed to price increases caused by disruptions across an interconnected international system, but they have supply security. Restricting U.S. exports would not remove those pressures and could compromise the production, refining incentives, and trading relationships that help sustain supply. The answer: understand how the entire barrel and the global market work—do not assume that turning off one export stream will solve the problem.
