Jefferies reported a notable decline in commercial ship traffic through the Strait of Hormuz over the past week, while freight rates, refining margins, petrochemical profits and select fuel cracks remain elevated compared with pre-conflict and February levels. Several market indicators point to constrained flows and tightening product markets even as some freight costs retreat from recent highs.

Key Points

  • Strait of Hormuz transit volumes fell 19% week-on-week to 25 vessels, down from pre-conflict levels of 120 vessels - impacting global crude flows and tanker logistics.
  • Singapore gross refining margins jumped to $21 per barrel from $5 at the end of February; gasoline, diesel and aviation fuel cracks are $29, $49 and $44 per barrel respectively - supporting stronger refining economics.
  • Energy and petrochemical markets tightened as about 800 million barrels of crude inventories were drawn down and petrochemical margins rose 101% versus February; spot LNG traded at $16/MMBtu, up 3% week-over-week.

Jefferies disclosed that daily commercial vessel transits through the Strait of Hormuz fell 19% in the last week, leaving average daily traffic at 25 vessels, down from pre-conflict levels of 120 vessels. The decline in traffic comes alongside volatility in freight and energy markets.

Freight rates eased by 30% during the week, yet they remain roughly double the amounts observed at the start of the conflict. Meanwhile, crude stockpiles have been drawn down by about 800 million barrels since the conflict began, supporting a tighter physical market.

Refining economics in Asia showed notable strength. Singapore gross refining margins averaged $21 per barrel over the past week, versus $5 per barrel at the end of February. At the product level, cracks for gasoline, diesel and aviation fuel were reported at $29, $49 and $44 per barrel respectively.

Damage to refining capability has also been material. Jefferies estimates that roughly 3.4 million barrels per day of refining capacity has been damaged since the conflict started, equating to about 3.5% of global refining capacity. That loss of processing availability is consistent with the elevated margins and product crack levels.

Trade flows are shifting as well. India’s share of Russian crude rose from 34% in April to 38% in May. The U.S. sanction waiver on Russian crude expired on June 17. In the pricing backdrop, the Russian Urals discount to Brent widened to $19 per barrel from $14 per barrel the previous week, while Dubai crude traded at a $7 per barrel discount to Brent.

At the retail level in India, oil marketing companies are reporting profits of 7 rupees per liter on petrol and 1 rupee per liter on diesel calculated using 15-day average pricing. Those companies increased retail fuel prices by 8% to 9% during May and June.

Pushing beyond fuels and refining, petrochemical margins were up 101% compared with February levels, and spot liquefied natural gas prices stood at $16 per million British thermal units, a 3% increase week-over-week.


Contextual note - The figures above reflect the data reported by Jefferies covering vessel movements, freight rates, inventory draws, refining margins and product cracks, damaged refinery throughput, trade share shifts, retail margins in India, petrochemical margins and spot LNG levels.

Risks

  • Reduced vessel transits through the Strait of Hormuz could continue to constrain physical crude flows and disrupt supply chains - this affects shipping, crude trading and downstream refining sectors.
  • Damage to roughly 3.4 million bpd of refining capacity (about 3.5% of global capacity) presents ongoing operational risk to product availability and price volatility - impacting refiners, fuel markets and petrochemicals.
  • Sanctions dynamics and changing trade patterns, illustrated by India’s increased intake of Russian crude and the expiration of the U.S. waiver on June 17, create uncertainty for crude price differentials and trade routes - relevant to oil traders and national fuel policy makers.
