Hormuz Tanker Traffic Slows Further as Oil Posts 5% Weekly Gain
Fresh attacks on Persian Gulf tankers extended months of disruption to crude and LNG flows, pushing oil benchmarks sharply higher through the week of August 10.
Tanker traffic through the Strait of Hormuz slowed further over the weekend of August 16-17, maintaining upward pressure on oil benchmarks that had already gained 5% in the week of August 10, reinforced by fresh attacks on vessels in the Persian Gulf, oilprice.com reported. ICE Brent crude front-month was trading at $91.05 per barrel on August 18, up from the $88.62 level in weekend reporting, while NYMEX WTI front-month stood at $84.06 per barrel.8
The disruption has compounded over months. Ships continued to transit the strait but in diminishing numbers, a pattern traceable to late June when vessel owners and operators pulled back sharply after U.S. Central Command strikes on Friday (2026-06-26) and Saturday (2026-06-27) in response to Iranian attacks, including one on the M/V Ever Lovely. The tanker Kiku, carrying more than 2 million barrels of crude oil according to U.S. armed forces statements, was among the vessels caught up in that escalation.5,4
The navigational problem is not solely one of threat perception. Jakob Larsen, chief safety and security officer at the Baltic and International Maritime Council, said the central part of the strait is mined and un-navigable, with only the inshore traffic zones close to Oman and Iran reportedly free of mines. That constraint concentrates traffic into narrow corridors where vessels are more exposed and easier to target.3
By late July, laden departures from Qatari terminals had effectively halted. Qatar's Al Areesh LNG tanker appeared east of the strait on Thursday (2026-07-30), marking the first crossing of a laden vessel since July 11, Montel reported. An analyst cited by Montel said the crossing did not signal a full reopening of traffic. Asian LNG JKM prices were at $21.88 per MMBtu on August 18, up 1.25% on the session, reflecting persistent tightness in spot cargoes available to buyers who would normally source from the Gulf.7
Europe's exposure runs through LNG import dependency. Oilprice.com flagged that the continent is especially vulnerable, with Hormuz traffic remaining severely disrupted. The ability to absorb disruptions depends partly on flexible Atlantic basin supply, but rerouting cargoes adds weeks to voyage times and absorbs vessel capacity, tightening the market further. ICE Endex TTF front-month was at €61.79 per MWh on August 18.8
The Trump administration has been examining ways to restore flow. Three people familiar with discussions told eenews.net that White House officials were considering a fee-based "VIP pass" naval escort program, which would offer commercial tankers a guided passage through the strait. The talks had not produced a formal proposal as of mid-June (2026-06-17), and no announcement has followed in subsequent weeks.2
The gap between isolated transits and a genuine reopening is meaningful for cargo markets. Seven laden outbound crossings since what oilprice.com described as an effective closure in late February 2026 does not constitute resumed commercial flow at scale, Montel's reporting from late May (2026-05-26) made clear. Vessel owners remain cautious about whether individual passages indicate a durable change in conditions or simply reflect opportunistic transits when threat levels briefly ease.1
Monday (2026-06-29) illustrated that dynamic precisely. Ships continued to cross the strait, Rigzone reported, but the number broadcasting their passage dropped as companies said weekend attacks had made them less willing to advertise their movements through automatic identification systems. Some operators chose to transit with AIS transponders switched off, a practice that reduces data visibility for analysts tracking throughput and introduces its own navigational risks.6
Gold at $4,413 per ounce and VIX at 15.65 on August 18 suggest broader risk-off positioning alongside elevated geopolitical uncertainty, though neither figure can be attributed solely to Hormuz. Heating oil futures were at $4.45 per gallon on August 18. The directional signal across Brent, JKM, and heating oil points to a market that has largely priced in disruption without yet pricing in resolution.8
The variable traders are tracking from here is whether the White House naval escort concept moves from internal discussion to operational deployment, and whether Iran treats individual tanker transits as provocations warranting further strikes. If the mined central channel remains impassable for standard laden VLCC drafts, even a naval presence cannot fully restore throughput to pre-February levels without significant mine clearance operations — an undertaking neither discussed nor sourced in any material available to this desk.2,3
