US touts six-month Hormuz high as mine clearance pays off

The unverified six-month peak in Hormuz traffic is, assuming it holds, a positive supply-side development that should curb the most aggressive upside scenarios for crude, yet the risk premium is unlikely to disappear while Iran keeps the strait closed and negotiations on agreed shipping routes remain stuck. Refined products may offer the clearer price signal, with a reported strike on jet fuel facilities at a key Saudi airport adding to a squeeze that has been mounting since the summer. Riyadh's alerts have also drawn traders' attention back to Saudi infrastructure, and with a bypass pipeline already offline (though repairs are advancing quickly), any further incident near Saudi energy assets would probably be priced in without delay. Given Washington's political interest in highlighting tanker volumes, traders may seek hard shipping data rather than official statements before relying on the improvement.

--- Washington is pointing to a six-month peak in Hormuz shipments as evidence that its mine clearance is working, but Iran still insists the strait is closed, and Riyadh's air raid warnings show the threat has not vanished.

Summary:

• On September 19, US Central Command chief Admiral Brad Cooper reported that oil and LNG shipments via the Strait of Hormuz in the past fortnight hit a six-month high, attributing it to US naval protection and mine clearance efforts.
• Cooper noted that the strait's main transit channels are free of mines and that Persian Gulf allies have shipped over one billion barrels of crude through it in recent months.
• Iran says it has closed the strait, talks on shipping routes have stalled, and Iran-war-linked drone strikes halted a Saudi bypass pipeline, worsening a supply squeeze since the summer.
• Riyadh experienced two early-morning air raid warnings on September 19, the first in the capital since the March-April height of the US-Iran war, and a reported strike hit jet fuel facilities at King Khalid International Airport.
• The Trump administration, under pressure from high fuel prices in a midterm year, has highlighted tanker volumes. On September 13, Energy Secretary Chris Wright said markets rely on about 10 million barrels daily through the strait and are tight but not severely so.

According to Admiral Brad Cooper, head of US Central Command, shipments of oil and LNG through the Strait of Hormuz have hit a six-month high in the past two weeks, and he credited US naval protection and mine clearance for the result. In a video message on September 19, Cooper said momentum is building and the strait's main lanes are now clear of mines.

Cooper also said Persian Gulf allies have shipped more than one billion barrels of crude through the waterway in recent months. This comes after a squeeze on global oil and product supply since the summer, partly due to Iran-war-linked drone strikes that shut a Saudi pipeline bypassing the strait. Iran still claims the strait is closed, and talks on shipping routes have failed, leaving the two versions of the situation unreconciled.

In a separate development that day, Saudi Arabia faced security concerns. On September 19, Riyadh saw two early air raid alerts, the first in the capital since the US-Iran war's peak in March and April, and Saudi civil defense said the danger had passed shortly after each. The Wall Street Journal, citing three officials, reported an air strike hit jet fuel facilities at King Khalid International Airport, with black smoke visible at the site—though that account relies on unnamed sources.

The political context matters too. President Donald Trump's administration, facing high petrol and diesel costs in a midterm year, has repeatedly cited tanker volumes recently. Energy Secretary Chris Wright said on September 13 that markets must continue to rely on an estimated 10 million barrels a day of crude and products through the strait, calling oil markets tighter than he'd like but not overly so.

Traders will likely monitor whether higher shipping volumes persist, whether more attacks on Saudi energy infrastructure occur, and whether shipping-route talks resume. The gap between Washington's view of a recovering waterway and Iran's claim of closure, plus the Riyadh alerts, leaves supply vulnerable to headlines in either direction.
