When could Americans feel the impact of G7’s 100 million-barrel oil release? Experts explain what households can expect

The G7 says its latest emergency energy action is meant to “shield households and businesses from price shocks,” but American consumers may have to wait before they see the benefit in their everyday fuel costs. The G7 members, which include Canada, France, Germany, Italy, Japan, the United Kingdom, and the US, agreed to release 100 million barrels of oil and refined fuel products through the International Energy Agency (IEA), with the release beginning immediately and to continue for four months.

The plan includes a “frontloaded substantial diesel release within the first 20 days,” And the US President apparently exited on this front. “Europe has just agreed to release a massive amount of their heavily stocked Diesel Oil,” Trump wrote on Truth Social following the announcement on Friday, October 2.

The move comes as oil and fuel markets face severe supply disruptions because of the Iran war and the crisis around the Strait of Hormuz. The G7 said its measures are intended to “stabilize immediate energy supplies” and “shield households and businesses from price shocks.”


But when will American households actually feel the difference?

Relief could come within weeks, but timing matters

Jason Bordoff, founding director of the Center on Global Energy Policy at Columbia University, told TIME that the timing of the release could make a major difference. “It makes a big difference if the release is in the next two weeks or if it's four months from now,” Bordoff says.

He said a large and clearly defined diesel release could have a meaningful effect if it reaches the market quickly.

“I think if we saw some announcement tomorrow from Germany or France that gave concrete, specific numbers for a substantial amount - 50 million barrels or so - of diesel, then it could have a real impact if this release actually happens in a timely fashion,” Bordoff predicted.

Bordoff also said that Americans could see diesel prices fall by as much as 25 cents per gallon after a few weeks if the release is timely. However, he also noted that markets remain uncertain about whether that will happen.

Diesel prices will go down, but as a temporary solution

“The emergency release by G7 members will put some downward pressure on prices, particularly global diesel prices,” Hamad Hussain, a climate and commodities economist at Capital Economics, told Al Jazeera. “However, the impact would be short-lived given that this is just a temporary solution to the supply crunch,” he predicts.

Why diesel could matter beyond the pump

The G7 has placed particular importance on diesel, saying a substantial amount will be released during the first 20 days. The group also called for increased production of refined products, particularly diesel, because of mounting pressure in that market.

Diesel is a crucial part of the transportation and manufacturing economy. Trucks, trains, farms and manufacturers rely heavily on it, meaning sustained high prices can push up transportation and production costs.

Jeff Colgan, a professor of political science at Brown University, told the publication that the effect on Americans could still be limited. “Releasing diesel could make a difference on price, especially in tight markets in Europe,” Colgan says. “But American consumers are unlikely to see much of a price drop from this policy move unless the diesel share of that 100 million barrels is very large.”

Markets may react before households do

There has already been a reaction in energy markets. David Bieri, an economist and associate professor of urban affairs and planning at Virginia Tech, told TIME that the announcement can influence prices by changing how markets view future supply.

“That's the main mechanism, because they want to influence market sentiment,” Bieri says. “Then, futures markets begin to price more optimistically, and then eventually the hope is that prices will come down.”

Why lower wholesale prices may not mean instant savings

Even if fuel prices fall in global and wholesale markets, the savings may take longer to reach households. Bieri cautioned that carriers and other businesses that absorbed higher fuel costs may first use lower prices to rebuild their margins.

“[They] have been bleeding on increased fuel costs,” he says. “This is going to be, if anything, a welcome reprieve for their profit margins, and they're not going to pass that on immediately to consumers.”

He also questioned how noticeable the reserve release itself could be for consumers.

“In fact, consumers might not necessarily notice it, ever. That's how insignificant the quantity itself is,” he says of the 100 million barrels. “But it's the importance of the cooperative signal that hopefully will make things better this fall.”

So, the first meaningful market effects could emerge within weeks if the promised diesel supplies are released quickly and in large enough quantities. But that does not guarantee an immediate or equal drop in household fuel costs.
