Brent crude oil prices slipped to around $114 a barrel on Thursday. That followed a gain of more than 1% in the prior session. Traders were weighing a reported diplomatic opening between Washington and Tehran against persistent fears of renewed conflict. Brent is the benchmark for roughly two-thirds of the world’s oil. It had settled at $115.32 on Wednesday, up 1.3%. US WTI crude closed at $102.78 that day, up 2.9%, before easing back above $101 a barrel on Thursday.
The swing shows how sensitive energy markets have become to every signal out of the region. Wednesday’s rise reflected fears of renewed US military action against Iran and further supply disruption. Thursday’s pullback came after new reports. Those reports said Vice President JD Vance had sent a letter to Iranian officials aimed at reviving negotiations. President Trump downplayed the outreach. He framed it as humanitarian aid rather than a formal overture.
Why Brent crude oil prices keep swinging on headlines
Under normal conditions, a single diplomatic letter would barely move a market this large. What’s different now is how thin the market’s safety margin has become. UBS analyst Giovanni Staunovo said global inventories “have fallen sharply.” He added that pledged strategic reserve releases are “largely completed.” That means the usual buffer governments use to calm price spikes has mostly been spent. UBS also pointed to record freight costs, constrained tanker capacity and recovering Chinese imports. These structural factors are likely to keep prices elevated regardless of how the diplomatic track unfolds.
Emirates NBD’s Nick Stadtmiller framed the environment simply: “Oil prices remain volatile as markets respond to developments affecting regional production and infrastructure.” UBS’s own base case has Brent holding near $110 a barrel at year-end. That would put today’s levels closer to the high end of its expected range than the low end.
The supply risk that won’t go away
Behind the day-to-day price moves sits a bigger structural story. The same Wall Street Journal report that described the Vance letter also carried another warning. It said Washington has warned several Gulf Arab governments to prepare for a possible renewed campaign against Iran. That warning applies once the 3 November US midterm elections are over. A letter today doesn’t rule out strikes next month, and traders know it.
Aviation has already adjusted to that reality. The European Union Aviation Safety Agency has extended its advisory against flying over Iran, Iraq, Lebanon and Jordan. The advisory also covers nearby Gulf waters, and it now runs through 16 November. Several carriers have pushed their own route restarts into early December. That is a sign the industry expects the underlying risk to persist well past any single news cycle.
What traders are watching next
Three triggers could move Brent meaningfully before year-end. A confirmed, substantive Iranian response to the reported US outreach would likely ease the risk premium further. A second trigger works the other way. If Washington is actually preparing post-midterm military action, rather than simply warning allies to plan for it, prices would almost certainly rise. A third trigger is tanker traffic. Any disruption to actual shipping through the Strait of Hormuz, rather than just airspace avoidance, could overwhelm even a calming diplomatic signal.
For now, the market is pricing genuine uncertainty rather than a clear direction. Brent’s roughly $1-a-barrel move this week is small by the standards of an active shooting-war scenario. It is large by the standards of a market that believes a deal is close.
Analysts at multiple banks have made the same basic point in different words this week: the floor under oil prices is higher than it was a year ago, and the ceiling is capped mainly by how quickly diplomacy or conflict resolves one way or the other. That leaves traders reacting to headlines in both directions rather than settling on a single view, which is why a single reported letter and a single warning to Gulf allies can both move the same market on the same day.
