Brent crude hits $110 as Gulf and Russia risks mount

Brent crude $110 was back on traders' screens on Friday afternoon, when the global benchmark pushed through that level for the first time since May before settling at $109.86 a barrel. That was a gain of $3.94, or 3.7%, on the day, Reuters reported, while U.S. West Texas Intermediate closed $3.44 higher at $101.41, its highest settlement since Sept. 17. The move arrived late in the session and took equities down with it.

What happened

Brent crossed $110 shortly after 2:30 p.m. Eastern time and finished at its highest closing level since May 19, NBC News reported. WTI's close above $100 was the first since September, a threshold watched closely by traders and consumers alike. Diesel futures rose more than 1% as well.

The trigger was a fresh round of escalation fears. Energy Aspects said both benchmarks reversed earlier losses on rumours of attacks on Saudi energy infrastructure. A Saudi-led coalition said it intercepted a ballistic missile aimed at Yanbu, the Red Sea port the kingdom uses to route crude around the Strait of Hormuz, and Rapidan Energy Group said initial reports showed no damage there.

Russia added a second supply worry. The Ryazan refinery suspended a primary crude distillation unit after a drone attack, two industry sources told Reuters, after President Volodymyr Zelenskiy said Kyiv was abandoning an energy-site ceasefire. Kpler analysts said intensified Iranian attacks had already driven Gulf crude flows sharply lower.

Why it matters

Oil is now feeding straight into the interest-rate debate. NBC noted that the climb in energy prices raises the odds of another Federal Reserve hike after September's quarter-point move. The Nasdaq 100 fell 2.5% and tech stocks shed more than $1 trillion in value on Friday, while energy was the best-performing S&P 500 sector.

Crypto felt the same squeeze. CoinDesk's live coverage showed the 10-year Treasury yield rising above 5.1% as crude jumped, with Strategy down 9.2%, Coinbase down 3.5% and Circle down 4% on the session. Bitcoin held near $81,500, a sign the selling was concentrated in equities rather than tokens.

This is a sharper move than the Gulf supply scare earlier in the week and it erases the relief seen during the Monday ceasefire bounce. Brent crude $110 also lands just as hotter consumer and producer inflation reports have already made bond investors nervous.

What's next

Policy makers are trying to add barrels. On Thursday the International Energy Agency backed a fuel release of over 20 million barrels, while the Department of Energy asked for bids to swap as much as 17 million barrels from the Strategic Petroleum Reserve. Kpler expects a slower and more uneven recovery in Hormuz flows without a comprehensive political deal.

Prediction markets see more upside as possible but not likely. On Polymarket's October WTI ladder, traders priced a touch of $105 at about 48% and a touch of $110 at about 22% as of 08:28 MSK on Oct. 17. A sustained Brent crude $110 would keep that higher strike in play into month-end.

The call

Polymarket prices "Will WTI Crude Oil (WTI) hit (HIGH) $110 in October?" at about 79% No as of 08:28 MSK on Oct. 17; the market settles on Pyth one-minute highs for the active ICE WTI contract. We call No: WTI will not trade at or above $110 at any point in October 2026. Friday's $110 print belonged to Brent, WTI still needs roughly another $8.60 from its close, and emergency barrels are being released. This is a dated record call, not investment advice.
