American consumers are feeling the immediate sting of the escalating conflict in the Middle East. On Monday, April 13, 2026, the average price for regular gasoline in the U.S. jumped to $4.15 per gallon, a sharp 93-cent increase from the same time last year. The situation is even more dire for the logistics sector, with diesel prices soaring to $5.68 per gallon—up over $2.00 from a year ago.
The primary catalyst for this surge is a high-stakes military standoff in the Strait of Hormuz, the world’s most vital oil chokepoint.
The Military Standoff: U.S. Blockade Commences
Following the collapse of peace talks in Islamabad led by Vice President JD Vance, President Donald Trump announced a significant shift in military strategy. As of 10:00 AM EST on Monday, U.S. Central Command (CENTCOM) officially began a blockade aimed at “all maritime traffic entering and exiting Iranian ports.”
While the U.S. has clarified that it will not impede freedom of navigation for vessels traveling to and from non-Iranian ports, the move is a direct response to weeks of Iranian interference that has throttled global oil supplies since the initial U.S.-Israeli strikes on February 28.
Market Reaction: Crude Hits Triple Digits
Energy markets responded with immediate volatility to the news of the blockade:
Brent Crude: Rose 7% to reach $102 per barrel.
West Texas Intermediate (WTI): Climbed 7.8% to $104 per barrel.
U.S. Stocks: Opened down by as much as 1% as investors weighed the impact of sustained energy inflation.
“Nostalgic for $5 Gas”: The Iranian Warning
The rhetoric from Tehran has intensified alongside the naval maneuvers. Iranian Parliament Speaker Mohammad Bagher Ghalibaf warned on social media that the U.S. blockade would lead to catastrophic price hikes, suggesting that Americans would soon look back fondly at gas prices under $5.00.
Expert Michael Lynch from the Energy Policy Research Foundation described the situation as “insult to injury” for a public already struggling with high living costs. He noted that while prices fluctuated slightly over the weekend, the dual U.S. and Iranian blockades create a perfect storm for sustained price hikes.
Trump’s Outlook: “They’re Wiped Out”
Despite the market turmoil, President Trump maintained an optimistic tone during a Sunday interview on Fox News. Addressing concerns over whether gas prices would continue to climb, he stated, “it could be a little bit higher, but it should be around the same.”
The President suggested that the military confrontation may be nearing its end, asserting, “I think this won’t be that much longer. They’re wiped out.”
