Vance blames the Iran war for the Republican midterm rout, and crude falls below $90

Vice President JD Vance distanced himself on Wednesday from President Donald Trump’s war on Iran, questioning its worth and blaming it for the Republican defeat in the midterm elections^1,2.

In a post on X on Wednesday morning, Vance said the war was the reason for the Democratic wave⁶. “The reason we lost is the war. The president himself said so last night,” Vance wrote⁶. He called the war the “real reason” for the rout^7,8 and the “obvious” reason Republicans lost¹⁰.

His comments came hours after Trump admitted the war had partly played a role in the Democratic gains, and Donald Trump Jr. was quick to appear to endorse the vice president’s message⁶. The assessment put at least a little daylight between Vance and Trump as the 2028 cycle begins⁶. Trump, for his part, said Defense Secretary Pete Hegseth is doing a very good job⁴.

Why it matters to investors

Oil reacted quickly. Crude prices tumbled on Wednesday after Vance’s remarks and fell below $90 a barrel³. The drop of around $8 a barrel deepened after Vance posted that “everyone knows” the war is why Republicans got pummeled and that “any honest conversation about where we go from here must start there”⁵.

Traders weighed signs that the election will add pressure on the White House to find an offramp from the conflict⁵. Senator Chuck Schumer, the likely Senate majority leader in the next Congress, vowed that Democrats will push to end the war⁵.

For energy markets, the combination matters more than any single statement: a vice president questioning the war in public, and an incoming Senate majority pledging to end it, both point toward lower odds of a prolonged conflict, which is how traders read the day^3,5.

What to watch

Not everyone accepts Vance’s account of the vote. A voter poll found that voters were more focused on government corruption and the cost of living than on the Iran war¹⁰. The war policy also does not have the support of all party members⁹.

The first question is whether the White House changes course or holds its position after the post, since Vance’s remarks came only hours after Trump’s own partial admission⁶. The second is how Democrats use their new majorities to press for an end to the war, as Schumer has vowed⁵.

For oil, the test is whether prices hold below $90 a barrel³ once the first reaction fades, or whether the move of around $8 a barrel⁵ reverses if the conflict continues.
