The “peace dividend” anticipated from early May diplomatic overtures has officially evaporated following the US rejection of Iran’s Pakistani-mediated peace proposal as “totally unacceptable” on May 11. The Strait of Hormuz remains a logistical graveyard, with tanker transits for April averaging just 12.9 ships per day, while approximately 181 million barrels of crude remain trapped in the Persian Gulf. The market has transitioned into an aggressive “hand-to-mouth” survival mode, where structural scarcity is the new baseline, further pressured by a drone strike near the UAE’s Barakah nuclear plant on May 17.

Recent Market Developments

  • Crude Futures Rebound: Front-month ICE July Brent futures surged to $111.01/b by May 18, a recovery of nearly $13/b from the May 7 low of $98.28/b, driven by the collapse of diplomatic talks and US forces disabling three Iranian tankers in the Gulf of Oman.
  • Dated Brent Structure: The physical market persists in extreme backwardation; while the physical differential moderated to +86.5 cents/b by May 15 due to a temporary overhang of prompt North Sea cargoes being displaced by US Strategic Petroleum Reserve (SPR) sour barrels, participants expect June arrival programs to be significantly “lighter”.
  • Singapore Fuel Oil Premiums: The 380 CST HSFO cash premium rebounded to 22.41/mt by May 15 after dipping to a near two week low of 17.17/mt on May 13 as regional inventories became “flooded” with Russian supplies.
  • Asian VLSFO Squeeze: The 0.5% Marine Fuel market tightened for five consecutive sessions, with the cash premium rising to $37.58/mt by May 18, driven by an acute shortage of blending components as refiners prioritize middle distillate yields, leaving the LSFO pool “almost empty”.
  • European VLSFO Tightness: Northwest European VLSFO remains structurally undersupplied; although FOB Rotterdam barge prices fell to $708.00/mt on May 7 following the wider complex, physical tightness persists as refiners divert low-sulfur components like LSSR and VGO to high-margin diesel production.
  • ARA Inventory Levels: Fuel oil stocks in the Amsterdam-Rotterdam-Antwerp hub rose 1.37% to 665,000 mt in the week ended May 7, though levels remain 13% below 2025 averages, maintaining high risk for compliant fuel availability.
  • Refinery Maintenance and Outages: Supply risks intensified as Saudi Arabia’s Jazan refinery reported an 85,000 b/d reformer outage, while Japan’s ENEOS shut its 175,000 b/d Kashima CDU for maintenance through August.
  • Bunker Demand Destruction: April bunker volumes in Singapore collapsed to a 14-month low of 4.31 million mt (down 8.7% month-over-month), and Fujairah sales hit a fresh record low of 128,135 cubic meters (down 80.9% year-over-year) as shipowners shifted demand to cheaper North Asian hubs like Zhoushan.

Singapore Hub: The Blockade-Induced Supply Void

Singapore is navigating a period of structural supply fragility as the regional blockade has severed its primary feedstock lifeline from the Middle East.

Supply Dynamics

  • Feedstock Vacuum: The hub recorded zero crude oil imports from the Middle East during the final week of April, a historic anomaly that forced regional refiners to source rare Atlantic Basin swing barrels, such as Algerian Saharan Blend (97,540 mt imported in early May).
  • Inventory Instability: Commercial onshore heavy distillate stocks hit a 51-week low of 19.5 million barrels in late April. While stocks recovered slightly to 20.08 million barrels by mid-May, availability remains thin for compliant bunker fuels.
  • Blending Constraints: Suppliers face severe challenges in LSFO blending as heavy sweet crudes and critical components like LSSR and VGO are being diverted to refinery feedstock pools to capture high middle distillate margins, leaving the LSFO blending pool “almost empty”.

The inventory recovery briefly observed in Singapore in late April — driven by an import surge from Brazil and the US flagged in Alkagesta’s 21 April insight — has since reversed, with commercial heavy distillate stocks falling back to a 51-week low as Western arbitrage flows slow and Middle Eastern supply remains severed.

Demand Dynamics

  • Bunker Demand Destruction: High flat prices and shipping risks triggered a collapse in demand; Singapore’s April bunker sales fell to a 14-month low of 4.31 million mt (down 8% month-over-month).
  • Market Migration: Bunker-only calls in Singapore declined to 3,438 in April as shipowners shifted demand to cheaper North Asian hubs like Zhoushan, where LSFO supplies are currently more plentiful.
  • Sluggish Utility Buying: Demand for 180 CST HSFO, typically supported by South Asian power generation, has remained sluggish due to mild temperatures and high prices straining utility fund management.

Europe (NWE & MED): The Import-Reliant Fortress

The European market is characterized by an acute VLSFO squeeze and a heavy reliance on the US to bridge the supply gap left by the loss of Persian Gulf barrels.

Supply Dynamics

  • NWE VLSFO Tightness: Northwest Europe remains acutely tight as expensive blending components (0.2%–0.3%S VGO and LSSR) are diverted to the more lucrative diesel and jet fuel pools.
  • ARA Inventory Levels: Fuel oil stocks in the Amsterdam-Rotterdam-Antwerp hub rose slightly to 665,000 mt in early May, yet inventories remain 13% below 2025 levels.
  • Mediterranean Scarcity: The Mediterranean remains “fundamentally dry” for sour barrels. While HSFO supply has been resilient despite geopolitical tensions, prompt cargo availability is extremely limited.
  • Secondary Feedstock Flows: European and Russian loadings of VGO fell 84.14% to just 44,103 mt in the week to May 8, further tightening the pool for secondary processing and blending.

The regrade dynamic identified in Alkagesta’s 27 April market insight — where refiners diverted low-sulfur components including LSSR and VGO to the more lucrative diesel and jet fuel pools — continues to define European VLSFO availability, with ARA fuel oil stocks now running 13% below 2025 averages.

Demand Dynamics

  • Subdued HSFO Appetite: High-sulfur demand remains weak across both NWE and the Mediterranean, characterized as “quiet” or “dull”. This has caused HSFO to trade at a premium to the 1.0% LSFO grade in an inverted Hi-Lo spread.
  • Blending Downgrades: Persistently weak demand for 1% LSFO has forced traders to regularly downgrade this material into the HSFO bunkering pool to clear prompt volumes.
  • Seasonal Utility Pivot: Market participants anticipate a sharp uptick in Mediterranean demand as regional utilities maximize fuel oil consumption as a natural gas substitute ahead of the peak summer cooling season.

Strategic Outlook: 2026 Market Roadmap

  • Short-Term Tactical (Q2 2026): The Escalation Premium

Market volatility will remain hyper-sensitive to headline risk. While a verified breakthrough would compress risk premiums, the fundamental supply shortfall will keep physical markets tight regardless of diplomatic status.

  • Mid-Term Structural (Q3 2026 – 2027): The Long Tail of Recovery

Restoring Middle Eastern export capacity will not be a “flick-of-the-switch” event. Material damage to high-complexity refineries like Al-Zour and Ruwais means the global market will likely remain short on refined products for five weeks to seven months once the blockade is lifted.

  • Long-Term Demand Re-Alignment

The IEA projects a full-year demand contraction of 420,000 b/d as record fuel costs—now accounting for up to 45% of expenditure for some airlines—trigger permanent demand destruction. Consequently, global inventories must be rebuilt above historical levels to account for a permanent “geopolitical risk premium”.
