Fill your tank today. By this time next week, $4.52 a gallon could look like a bargain.
The ceasefire between the United States and Iran, brokered after a U.S. military operation reopened the Strait of Hormuz this spring, is set to expire tomorrow. The Associated Press and Reuters, each citing multiple administration officials, have reported the lapse date in recent days, though the White House has neither published the agreement’s full terms nor confirmed a precise expiration time on the record.
Meanwhile, Brent crude settled near $109 a barrel on the Intercontinental Exchange in late May 2026. The last time the global benchmark sustained prices above $110, in the spring of 2022, the U.S. national average for regular gasoline vaulted past $5 a gallon within roughly three weeks. Today’s starting price is already higher than it was at the equivalent moment four years ago.
American drivers are closer to $5 gasoline than they are to $4. The single biggest variable standing between here and there is a diplomatic agreement that may not survive the weekend.
The 2022 precedent, week by week
The U.S. Energy Information Administration’s weekly retail gasoline series shows regular gasoline hit $5.006 per gallon for the week ending June 13, 2022. Brent had crossed $110 in mid-May of that year. The lag between the crude spike and the retail peak was about three weeks, a delay driven by refinery processing time, wholesale contract cycles, and the logistics of trucking fuel to roughly 150,000 stations across the country.
The parallel is not perfect. In 2022, Russia’s invasion of Ukraine was the catalyst, and global supply chains were still recovering from pandemic-era disruptions. U.S. domestic crude production is higher now than it was then, running above 13 million barrels per day according to the EIA’s most recent Weekly Petroleum Status Report. That added output provides a partial cushion.
But the math still tilts against drivers. In May 2022, the national average sat near $4.40 when Brent first breached $110. Now it is already $4.52, which means the runway to $5 is shorter. Gulf Coast refinery utilization is running above 93 percent, according to the same EIA report, leaving the industry little room to absorb a crude-price shock by ramping up throughput. And summer driving season, historically the period of highest U.S. gasoline demand, is compounding the pressure.
What a ceasefire collapse would actually disrupt
The Strait of Hormuz is a 21-mile-wide channel between Iran and Oman through which roughly one-fifth of the world’s traded petroleum passes daily. When the U.S. military operation concluded and the ceasefire took hold in April, tanker traffic resumed and war-risk insurance premiums on Strait transits dropped sharply. A lapse would reverse both trends almost immediately.
The White House declared in April that hostilities had “terminated,” a legal framing the administration used to argue that the War Powers Resolution clock did not apply. The Associated Press reported at the time that congressional leaders received correspondence making that case. If fighting resumes, the legal and military questions reopen at once: Does the president need fresh authorization from Congress? Will the Navy re-escort commercial tankers? Will Lloyd’s of London and other marine insurers spike premiums overnight?
Iran’s public posture adds another layer of uncertainty. Tehran has not issued a formal statement on whether it intends to honor the ceasefire terms beyond the expiration date, and Iranian state media coverage of the agreement has been sparse. Without a clear signal from both sides, traders and insurers are left pricing in ambiguity, which in commodity markets almost always means pricing in risk.
Why a gas-tax holiday would barely register
President Trump has said he will ask Congress to suspend the federal gasoline tax, currently 18.4 cents per gallon for regular and 24.4 cents for diesel. That rate has not changed since 1993. The president cannot waive the tax unilaterally; legislation is required, and as of late May 2026, no bill text or Treasury guidance had surfaced.
Even if Congress acted overnight, the savings are thin. Stripping 18.4 cents from a $4.52 gallon brings the price to $4.34, still higher than the national average at any point between 2015 and 2021. And it does nothing to address the underlying crude-price pressure. If Brent stays near $109 or climbs on a ceasefire collapse, rising wholesale costs would swallow the tax savings within days. Drivers in high-tax states like California and Pennsylvania, where combined state and federal levies exceed 70 cents a gallon, would feel even less relief.
The political appeal of a gas-tax holiday is obvious. The economic impact is not. The Congressional Budget Office estimated in 2022 that a full-year federal gas-tax suspension would cost the Highway Trust Fund roughly $20 billion in revenue, money that funds road and bridge maintenance. Congress declined to pass a suspension then, and the fiscal math has not improved since.
What could keep prices from spiking
Not every scenario leads to $5 gasoline. Several circuit breakers exist, though none is guaranteed.
A quiet ceasefire extension. Back-channel diplomacy between Washington and Tehran, possibly mediated by Oman or Qatar, could produce a rollover without a public announcement. Markets would read the absence of hostilities as a positive signal, and Brent could drift lower.
A Strategic Petroleum Reserve release. The SPR held approximately 348 million barrels as of the EIA’s most recent weekly report, well below its 2010 peak of 727 million barrels but still a meaningful buffer. A coordinated release, especially if paired with commitments from other International Energy Agency member nations, could blunt a crude spike for weeks. The Biden administration used this tool aggressively in 2022, releasing roughly 180 million barrels over six months. Whether the current White House would follow that playbook is an open question.
An OPEC+ output signal. Saudi Arabia and the United Arab Emirates hold the largest spare production capacity within the group. If Riyadh signaled even a partial ramp-up, traders would price in additional supply before a single extra barrel shipped. But OPEC+ has its own internal politics; members who have been restraining output to support prices may not welcome a sudden reversal.
Record U.S. production. American oil output has been running at or near all-time highs. If domestic producers respond to elevated prices by accelerating drilling, additional supply could reach the market within months, though not fast enough to prevent a near-term spike.
The existence of these potential offsets is why a single geopolitical event rarely produces a straight-line price move. Markets weigh probabilities, and right now the range of outcomes is unusually wide.
What drivers should actually watch this week
The signals that matter over the next seven to ten days are specific and trackable:
- Brent settlement prices on ICE. If Brent closes above $112 for two consecutive sessions, the 2022 pattern suggests wholesale gasoline will follow within days.
- Gulf Coast 3-2-1 crack spreads. This refinery margin indicator, published daily by the CME Group, shows how much refiners earn turning crude into gasoline and diesel. A widening crack spread means refiners are passing crude costs through to consumers faster.
- War-risk insurance premiums for Strait of Hormuz transits. Lloyd’s market reports and shipping-industry trackers publish these figures. A spike signals that tanker operators expect trouble, even before any shots are fired.
- White House or State Department statements on the ceasefire. Silence is not necessarily reassuring. But an explicit extension or a new diplomatic framework would be the clearest bearish signal for oil prices.
- The EIA’s Weekly Petroleum Status Report. Released every Wednesday, it provides the most authoritative snapshot of U.S. crude inventories, refinery runs, and gasoline demand. The next release will capture the first full week of market reaction to whatever happens at the Strait.
The price you pay Friday depends on what happens Thursday
Gasoline at $4.52 is already straining household budgets. According to the U.S. Census Bureau, more than 130 million Americans commute by car. For many of them, fuel is the most visible weekly expense after rent or a mortgage payment. The national average has not been this high outside of the 2022 spike and the brief post-Hurricane Katrina surge in 2005.
What makes this moment distinct is how specific the threat is: a known diplomatic deadline, a quantifiable crude-price threshold, and a historical precedent that played out in full public view just four years ago. In 2022, retail gasoline moved from uncomfortable to record-breaking in less than a month once crude prices stayed elevated and no policy intervention arrived in time.
Every ingredient for a repeat is on the table. The counterweights, record domestic production, a still-sizable SPR, potential OPEC+ flexibility, exist too. But none of them activates automatically. Each requires a decision by someone with the authority to act. And the first decision that matters is the one due tomorrow: whether the ceasefire in the Strait of Hormuz holds, or whether it doesn’t.
