Oil Surges After Trump Declares Iran Ceasefire 'Over.' Russia Diesel Ban and Used EV Prices Add to the Pressure.

Since U.S. strikes on Iran began reshaping global energy markets, the situation escalated sharply on Wednesday, July 8. At the NATO summit in The Hague, Netherlands, President Trump told reporters the ceasefire is "over" and that "we're going to hit them hard tonight." He described Iranian leadership as "scum." NATO Secretary General Mark Rutte, sitting beside Trump, called Tuesday's U.S. strikes "absolutely necessary," saying Iran had violated the ceasefire by attacking commercial vessels in the Strait of Hormuz, according to CNBC.

The market response was immediate. International Brent crude futures closed up 5.7% at $78.37 a barrel. West Texas Intermediate rose 4.8% to $73.84. The Dow Jones Industrial Average fell 595 points, or 1.1%, on the day. The S&P 500 dropped 0.3%, while the Nasdaq managed a 0.1% gain, steadied partly by a rebound in chip stocks after the previous session's selloff.

A Second Supply Shock: Russia Bans Diesel Exports

The Iran escalation is not the only force hitting energy markets right now. Russia's Deputy Prime Minister Alexander Novak announced Wednesday that Russia is banning diesel exports entirely, according to ZeroHedge, citing a government meeting with President Vladimir Putin. The move follows weeks of Ukrainian drone strikes on Russian refineries that pushed crude-processing rates to multi-year lows and forced fuel rationing across multiple Russian regions.

Russia supplied roughly 11% of global diesel in 2025, per Bloomberg data compiled by analytics firm Vortexa. Even before the formal ban, Russian diesel and gasoil exports during the first three weeks of June averaged about 490,000 barrels per day — barely half of 2025's full-year average. The ban comes on top of existing restrictions on most gasoline and jet fuel shipments.

Global diesel margins had already disconnected from crude oil prices, rising to record highs. Removing Russia from the export market structurally tightens supply further, independent of whatever happens with Iran.

Consumers Are Already Absorbing the Hit

AAA reported this week that the national average gas price stands at $3.80 a gallon, up roughly 21% from a year ago. That figure had been drifting lower before Wednesday's oil spike.

The elevated gas prices are redirecting buyers toward used electric vehicles, and that shift is showing up clearly in pricing data. Cox Automotive's Manheim Used Vehicle Value Index for EVs increased 12% in June compared with June 2025, according to Cox's Wednesday report. Non-EVs rose just 1.7% over the same period. Wholesale EV prices have increased every month this year, pushing the average to roughly $30,400, an 11.5% jump year-to-date. The average used EV retail listing price as of May was $37,083, per Kelley Blue Book.

Used EV sales reached 42,923 units in May, up 24.7% year over year, Cox reported. Tesla led with an estimated 15,353 units, followed by Hyundai, Chevrolet, Ford, and BMW.

New EVs tell the opposite story. Multiple automakers reported sharp new-EV sales declines in the second quarter. The federal $7,500 purchase incentive ended in September 2025, and after a brief demand spike that pushed EVs to roughly 10% of all vehicles sold that month, sales fell sharply.

The Strongest Case Against Alarm

Some analysts argue the market is overreacting to geopolitical noise. Daniela Hathorn, senior market analyst at Capital.com, noted Wednesday that "markets had become comfortable with the idea that the conflict would gradually fade into the background" — which means today's moves partly reflect a correction from excessive optimism rather than a fundamental new catastrophe. If Trump's stated intent to strike Iran is a negotiating posture rather than a sustained campaign, oil could retrace quickly. Cox Automotive's Jonathan Gregory also flagged that a surge of off-lease EVs expected in the second half of 2026 could pressure EV prices downward if gas prices fall. That scenario depends on the Iran situation de-escalating faster than Trump's Wednesday language suggests it will.

NATO Friction, Spain, and Fed Uncertainty

The Hague summit added a separate stress point. Trump called Spain a "terrible partner" in NATO, said "cut off all trade with Spain, please, including visits," and called Spanish officials "bad people," according to CNBC. Spain spent 2.1% of GDP on defense in 2025 — up from 1.4% in 2021 — but remains the only NATO member that did not commit to the alliance's 5%-of-GDP target by 2035. Rutte acknowledged Spain's progress but conceded "issues we have to solve." Spain's prime minister's office told Reuters it viewed Trump's remarks as routine and said bilateral ties remained beneficial.

Adding to the uncertainty, minutes from the Federal Reserve's June meeting — Chairman Kevin Warsh's first — showed a divided central bank. The minutes stated that "many participants indicated that the appropriate level of the federal funds rate would be within or slightly below the current target range at the end of this year," but offered no clear path forward on inflation.

The open question heading into Thursday is whether Trump follows through on Wednesday's threat of renewed strikes on Iran, which would determine whether Brent crude holds above $78 or pushes toward the $80-plus range that would hit consumers and freight costs across the economy.
