Key Highlights

  • Brent crude fell about 1.7% to a USD 113.88 settle on October 27, 2026, even after the Houthis said they hit Saudi Arabia's Ras Tanura refinery, which affects United States Oil Fund (NYSEARCA:USO).
  • Published Brent readings conflict by about USD 6, from USD 109.73 to USD 116.26 across settle, early October 28 and intraday quotes, so levels here are labelled by time.
  • West Texas Intermediate settled near USD 99.90, with another reading at USD 100.21, and Gulf crude exports run about 65% of pre-conflict levels, according to ANZ. The reading used depends on timing.
  • Iran, Saudi Arabia, Turkey and Pakistan talks eased the risk premium, but the Saudi damage claim is unconfirmed, leaving United States Oil Fund (NYSEARCA:USO) exposed to headline swings.

Why Oil Fell Despite the Claim

Brent settled at USD 113.88 on October 27, 2026, down 1.67%, which implies a prior settle near USD 115.81, simple arithmetic on two published numbers. The Houthis said they struck the Ras Tanura refinery with a missile, but the claim is unconfirmed. Talks involving Iran, Saudi Arabia, Turkey and Pakistan eased the risk premium. Other readings include USD 109.73 and USD 109.82 early on October 28, USD 115.17 in the October 28 quote and USD 116.26 intraday on October 27, so the settle is used as the anchor. Oil remains near six-month highs. Treating the settle as the anchor avoids mixing time stamps, because intraday prints can swing by several dollars in a session.

What Sets the Price

Supply is the key driver. ANZ estimates Gulf crude exports at about 65% of pre-conflict levels and Strait of Hormuz flows at about 60% of normal, so any disruption or reopening shifts prices fast. United States Oil Fund (NYSEARCA:USO) holds near-month crude futures, so its value follows oil futures rather than company profits, and rolling contracts can add cost or gain. This article states no verified price move for United States Oil Fund (NYSEARCA:USO). Oil also matters for inflation expectations, airlines and the Federal Reserve, which decides on October 28, 2026. Contract rolls matter because the fund must sell expiring futures and buy later ones, and when later contracts cost more, the roll drags on returns.

Risks and What to Watch

Risks run both ways. A confirmed strike or a collapse of talks could lift prices, while a deal on Gulf shipping could erase the risk premium quickly. Source conflicts on levels show how headline-driven the market is. Refiners fell sharply on October 27 for reasons not verified, and ExxonMobil and Chevron report on October 30. Investors in United States Oil Fund (NYSEARCA:USO) face futures-curve effects and leverage-free but volatile swings. Nothing here is advice or a forecast. Gulf shipping headlines can reverse sentiment within hours, so even a modest diplomatic breakthrough or a new strike can swing prices by several dollars. The fund does not use leverage, but oil's volatility alone can produce large daily moves, and the position can lose value quickly if prices fall. Investors should size exposure with that in mind.

Where Things Stand

Brent fell about 1.7% because talks among Iran, Saudi Arabia, Turkey and Pakistan eased the risk premium, even as the Houthi claim on Ras Tanura remained unconfirmed. Readings of USD 113.88 versus USD 109.73 show how uncertain levels are. For United States Oil Fund (NYSEARCA:USO) holders, the price depends on futures and on supply headlines, with Gulf exports near 65% of pre-conflict levels. The Fed decision on October 28, 2026 adds another macro swing. The Fed decision on October 28, 2026 and the supermajors' results on October 30 are the next catalysts.
