Crude oil markets closed the week with a sharp rally on Friday, leaving consumers facing another weekend of higher prices at the fuel pumps. Pump prices typically track crude costs with a lag, so a sustained move back into triple digits tends to filter through to motorists in the weeks that follow.

WTI crude finished the session at its highest level since September 21, climbing back above $100 per barrel. The benchmark's last trade was $3.33 at $101.30, while Brent crude — the international gauge for seaborne oil, in contrast to WTI's role as the US benchmark — touched $110 for the first time since May.

The late-day surge — a jump from $98 to $101 in the final hours of trading — pointed to lingering concerns about a potential US attack on Iran. Attention has centered this week on reports that the US military is preparing MOAB strikes, referring to the Massive Ordnance Air Blast weapon, one of the most powerful conventional bombs in the American arsenal. President Trump did not push back against those reports when given the opportunity, though he previously wrote that the United States would not attack Iran before the midterm elections.

The geopolitical uncertainty comes at a difficult moment for the administration. Republicans are trailing in the polls, and the White House announced Friday that new press secretary Katie Zacharia was asked to step down after just five days on the job. It was also disclosed that the US fiscal 2026 budget deficit was the largest in five years. Trump may view a fresh strike as a Hail Mary opportunity to shift the narrative around the war and inflation.

Iran, for its part, could seek to escalate to push oil prices still higher, exacting a toll on global consumers in order to gain leverage. The country sits at the mouth of the Strait of Hormuz, the narrow waterway that carries a large share of the world's seaborne oil, which is why even the threat of a wider conflict moves energy prices so sharply.

Notably, there was no specific catalyst in Friday's news flow for the magnitude of oil's gain. The move rippled into stock and bond markets, contributing to one of the Nasdaq's worst days of the year; the index was last down 2.2%. Oil spikes tend to hit equities broadly because they lift cost assumptions for airlines, shippers and manufacturers while amplifying inflation concerns.

From a technical standpoint, WTI faces resistance at the September high of $106.75, with some room to run before that level. The war high stands at $119.48, set in early March, though the highest close was $112.95, reflecting extreme volatility on some days during the conflict. In the near term, traders will be watching weekly US inventory readings for signs of supply tightness, while headline risk out of Washington keeps volatility elevated.

If oil markets remain quiet over the next two weeks, attention will likely turn to the post-midterms landscape. The vote is set for November 3, and its outcome could shape what follows — some reports suggest Trump could make Secretary of Defense Pete Hegseth a scapegoat. The concern, however, is that the vote will not change the equation much unless remaining Republicans insist that Trump end the conflict.
