Brent Holds Above $100 as Iran Hits Hormuz Tankers

undefined

Iran has stepped up tanker attacks near the Strait of Hormuz, pushing transits to a two-month low and keeping the Brent crude oil price above $100 a barrel.

Iran intensified its attacks on tankers in and around the Strait of Hormuz this week. Traffic through the waterway fell to its lowest level in more than two months and the crude oil price stayed above $100 a barrel. Maritime security data show 12 attacks on crude, LNG and LPG carriers between September 28 and October 5, the highest weekly total since the US-Iran war began in February. Brent futures rose as much as 5% on Thursday to about $105 and held near $103 on Friday. US benchmark WTI traded around $90.

What Happened in the Strait of Hormuz?

Ship-tracking data show that seven commodity carriers transited Hormuz on Tuesday, the thinnest daily flow since July 23. Crude moving through the strait fell 27% from a wartime high the previous week to at least 10.1 million barrels a day. That matches the September average but is still about 74% of the pre-war level.

The attacks came as Gulf producers had been lifting exports and flows were recovering toward pre-war levels. Iran struck at least one tanker in the Gulf of Oman. The escalation follows a September exchange in which US forces destroyed five Iranian oil tankers after Iranian missile attempts against a Navy warship. Tehran then said it had targeted 10 vessels near the strait, including two US ships. US Central Command disputed that any warship was hit.

Why Did Oil Prices Jump Again?

Oil rose because each attack reduces the number of owners willing to send ships through the only sea route for roughly a fifth of global crude trade. Brent had slipped to about $99 on Wednesday before the rebound. A report that the White House asked the Pentagon for options to strike Iran before the November 3 midterm elections added to the Thursday move.

Freight and insurance costs show the strain. The daily cost of moving crude from the Persian Gulf to China reached a record of about $1.3 million this week. That compares with an average near $60,000 a day last year. War-risk insurance premiums are elevated, and a shortage of available vessels is spilling over into other trade routes.

How Are Producers and Governments Responding?

Saudi Arabia has been conducting ship-to-ship transfers to move barrels around the chokepoint, a workaround that lifts costs and cannot replace full pipeline or terminal capacity. Washington has combined military pressure with economic measures. It sanctioned 17 tankers carrying Iranian crude, fuels and petrochemicals this week, even as President Trump described talks with Tehran as productive.

The mixed signals have kept diplomacy from reassuring traders. Iran treats tanker traffic as leverage in the wider conflict, while the US treats Iranian oil exports as a target. Shippers sit between those two positions.

Geopolitical Dimension

Hormuz remains the central constraint in the conflict. Roughly 20 million barrels a day of crude and products moved through it before the war. Bypass routes through Saudi and Emirati pipelines cover only a fraction of that volume. Iran's ability to harass shipping cheaply, through missiles, drones and mines, gives it influence out of proportion to its naval strength.

For Gulf producers, the risk is that higher exports invite more attacks. For Asian importers, especially China, India, Japan and South Korea, the exposure is to both price and physical availability. Refiners in those markets compete for cargoes that bypass the strait, which tightens spot markets and lifts regional premiums over futures.

What Comes Next for Oil Prices?

The near-term path depends on whether transits recover or keep falling. If attacks continue at the pace of the past two weeks, flows are likely to stay below the September average and Brent is likely to stay above $100, with spikes on any US military action. A confirmed deal between Washington and Tehran would remove the risk premium quickly, as earlier negotiating headlines showed. Prices have repeatedly swung between roughly $99 and $108 within days.

Pump prices follow with a lag. Diesel, which is sensitive to Middle East supply, is likely to reflect the freight and insurance spike over the next several weeks. Central banks that were counting on lower energy costs to ease inflation face a less favorable path through the end of the year.

Outlook

Iran's increased attacks have cut Hormuz transits to a two-month low and kept Brent above $100. Record freight rates, sanctions on 17 tankers and reported US strike planning point to a volatile period ahead. The key variables over the next three to twelve months are the daily transit count, the pace of attacks, and whether talks between Washington and Tehran produce a durable arrangement for shipping.
