The Trump administration is expected to announce as soon as Wednesday that it will temporarily lift federal smog-cutting restrictions on summer-blend gasoline to curb rising energy prices stemming from the war on Iran, according to two sources familiar with the matter. The change could shave several cents per gallon off retail prices and provide relief to both consumers and refiners struggling with tight fuel supplies.

Why it matters

This move is part of a broader effort by the White House to contain the economic and political fallout from rising energy costs as peak summer driving season approaches. The U.S. normally switches to summer gasoline blends to reduce air pollution, but the administration is prioritizing lower prices over environmental concerns during this period of supply disruptions.

The details

The Trump administration plans to allow fuel retailers to continue selling gasoline blended with 15% ethanol, known as E15, throughout the summer driving season when stricter rules normally limit its use in much of the country. Analysts say the change could shave several cents per gallon off retail prices and provide relief to both consumers and refiners struggling with tight fuel supplies.
