Abbott declares statewide disaster to ease diesel costs amid Iran war fallout

Key points

• Abbott’s 30-day disaster declaration allows the use of untaxed dyed diesel on Texas roads, increasing supply without waiving the 20-cent per gallon fuel tax.
• The order suspends Texas Low Emission Diesel rules and raises weight limits for fuel, agricultural, and timber loads to reduce transportation costs.
• Abbott requested a federal EPA waiver for ultra-low sulfur diesel requirements to further boost fuel availability across 110 counties.
• Diesel prices in Texas have risen from $3.30 in February to an average of $5.86, with some reports citing peaks near $5.97, driven by global supply disruptions.
• The price spike is linked to the ongoing U.S.-Israel conflict with Iran, which has restricted Middle East oil and gas exports for seven months.

Background

Fuel prices have been climbing steadily since late 2025, with national diesel averages hitting record highs in September 2026. Previous coverage noted that geopolitical tensions, including the Iran conflict and disruptions in the Strait of Hormuz, have kept crude oil prices elevated, with Brent crude near $105 per barrel. California has faced extreme pricing, with some stations hitting display caps, while other states have seen significant increases. This latest Texas action is part of a broader national response to energy affordability concerns ahead of the midterm elections.

How outlets are covering it

The Texas Tribune and KFOX reported the core details of Abbott’s disaster declaration, emphasizing the suspension of dyed diesel restrictions and the request for an EPA waiver. FOX 7 Austin provided additional specifics, noting that the order covers all 254 counties and that weight limits were raised to 95,000 pounds for certain loads. CDLLife focused on the practical implications for trucking, highlighting the suspension of off-road diesel restrictions and increased weight limits. Democrats, including state Rep. Gina Hinojosa and the Texas Democratic Party, criticized the governor for not waiving the state gas tax, blaming President Trump’s foreign policy and tariffs for the price surge. Abbott’s office maintains that the governor lacks the authority to unilaterally waive taxes. The sources generally agree on the facts of the declaration but differ in their framing of the political responsibility for the crisis.

Why it matters

The disaster declaration directly impacts the cost of goods for Texas consumers, as diesel is essential for farming and shipping. Higher fuel costs are passed through to grocery prices and other consumer goods. The move also has significant political implications, as affordability is a central issue in the 2026 midterm elections. Abbott’s actions aim to mitigate economic pain for voters, while Democrats use the crisis to challenge his administration and federal policy. The effectiveness of the measures in lowering prices will be closely watched in the coming weeks.

What to watch

The 30-day disaster declaration can be extended indefinitely. The outcome of the EPA waiver request will determine if additional federal relief is granted. Political pressure on Abbott to waive the state fuel tax is likely to intensify as the November 3 elections approach. Monitoring diesel prices in the coming weeks will reveal if the supply-side measures have any tangible effect on retail costs.
