Bunker Prices Plunge 20% as Iran De-escalation Drags Oil Markets Down

Singapore very low sulphur fuel oil has dropped $205 a tonne — 20.1% — in under two weeks, sliding from $1,019.50 on October 30 to $814.50 yesterday, according to Ship & Bunker assessments. For an owner lifting a standard 3,000-tonne bunker stem, that reversal is worth $615,000 in savings compared with the end of last month.

The correction is global. Ship & Bunker's 20-port average VLSFO price fell 15.7%, from $999 a tonne on October 30 to $842. In Fujairah, VLSFO was assessed at $813.50, while Rotterdam traded considerably cheaper at $710. The spread between the hubs gives operators room to shop port calls for stem economics that were irrelevant a fortnight ago.

Why are prices falling now?

Oil markets are tumbling on growing optimism that the conflict with Iran could be heading toward a diplomatic resolution, alongside recovering Middle Eastern oil flows. Brent crude briefly fell below $90 a barrel on Tuesday, its lowest level since late August. Peace negotiations remain unsettled, though, and that uncertainty is still generating considerable volatility in crude and bunker prices alike.

The retreat interrupts one of the sharpest fuel rallies of the year. Splash reported on November 3 that Singapore VLSFO had climbed back above $1,000 a tonne for the first time since March, with the Iran conflict having almost doubled bunker prices since February.

Even after the latest slide, Singapore fuel still costs roughly 56% more than immediately before the war began on February 28. Owners who budgeted on pre-war fuel curves remain badly underwater on their voyage economics.

What does the fuel bill look like for the full year?

Clarksons Research has put shipping's total bunker bill this year at a record $220 billion. Speaking at the IBIA Annual Convention in New York yesterday, Clarksons managing director Steve Gordon estimated the global bunker market at 290 million tonnes annually.

Fuel demand keeps rising despite modern ships burning around 50% less fuel than vessels built 15 years ago. The explanation lies partly in longer voyages caused by geopolitical disruption — reroutings that stretch distances and burn extra tonnes. Clarksons expects tonne-mile demand to rise by around 1% to 1.5% this year, with average shipping distances having increased approximately 10% during the current decade.

What does this mean for carriers and charterers?

For owners, the 20% price drop restores breathing room on routes where bunker costs had been eroding margins faster than freight could recover them. Charterers negotiating bunker adjustment factors will see the reference prices fall in coming weeks, though the lag in index-linked surcharges means the relief arrives unevenly.

The savings are real but conditional. A single diplomatic setback could push Brent back above $90 and reverse the Singapore assessment toward the $1,000 mark it breached on November 3. Anyone fixing long-dated business on yesterday's $814.50 assessment is accepting that risk.

For liner carriers, the arithmetic is simpler: a 3,000-tonne stem costing $615,000 less than two weeks ago goes straight into slot economics on Asia–Europe and transpacific loops, where bunker surcharges remain a visible line on every shipper's invoice.

Even with the reprieve, 2024 stands as the most expensive year for marine fuel on record at $220 billion. Whether 2025 brings relief depends largely on the durability of any Iran settlement — and the $205-a-tonne question is whether this week's prices mark a turning point or a pause in a still-inflated market.
