Fuel Oil 180 cSt (1.0% sulphur, Low Sulphur Fuel Oil) is a residual fuel oil produced at the bottom of the refining barrel, traditionally used as marine bunker fuel and industrial boiler fuel. It is the lighter-viscosity counterpart to the heavier 380 cSt grade, making it suitable for vessels and industrial users without high-capacity fuel preheating systems. The Rotterdam (ARA) hub is Europe's primary pricing and bunkering reference for residual fuel oil.

Since the IMO 2020 global sulphur cap took effect on 1 January 2020, the fuel oil market split structurally between IMO-compliant low-sulphur grades (VLSFO at 0.5% and LSFO at 1.0%) and legacy high-sulphur 380 cSt fuel oil, which now trades at a persistent discount and is restricted to vessels equipped with exhaust gas cleaning systems (scrubbers/EGCS). This regulatory restructuring created a durable premium for 180 cSt and other LSFO grades over their high-sulphur counterparts.

Global Fuel Oil Pricing Hubs

Residual fuel oil prices vary by region due to refinery supply, local demand, and shipping costs:

  • Rotterdam (ARA) — Europe's primary fuel oil trading and bunkering hub. Rotterdam prices are benchmarked by platts assessments and reflect NWE refinery output and vessel bunkering demand along the main Atlantic shipping lanes.
  • Singapore — the world's largest bunkering port by volume, Singapore's fuel oil prices reflect Asian refinery flows, VLCC and container shipping demand on East–West routes, and Chinese refinery crude slate decisions.
  • Fujairah — the key Middle East bunkering hub at the Strait of Hormuz, supplying vessels on the Arabia–Asia and Arabia–Europe routes with both VLSFO and residual fuel grades.

Key Fuel Oil 180 Price Drivers

  • Brent crude price — the primary input cost; residual fuel oil typically trades at a significant discount to Brent on a per-tonne basis, but the absolute price tracks crude movements closely
  • Crude slate complexity — refineries processing heavier, more sulphurous crude produce more residual fuel output; a shift to lighter crude slates reduces supply and supports prices
  • LSFO/HSFO spread — the premium of compliant low-sulphur fuel over HSFO; a wider spread reflects greater regulatory compliance pressure and signals tighter LSFO supply relative to HSFO
  • IMO 2020 and sulphur regulations — structural demand shift from HSFO to LSFO grades since 2020; future regulatory tightening (ECA expansion, CII ratings) could reshape demand further
  • Marine bunkering demand — global shipping activity, fleet size, and vessel speed determine aggregate fuel demand at major ports
  • ARA storage levels — Insights Global weekly fuel oil inventory data for the ARA region is the most closely watched short-term supply signal in Europe
  • Power generation demand — industrial and power-sector offtake in the Middle East and Asia provides a floor for residual fuel demand outside marine bunkering

How Fuel Oil 180 Is Purchased

Fuel Oil 180 is purchased either as bunker fuel (delivered on board at port, in quantities of 500–3,000 MT) or in cargo parcels for industrial users (10,000–30,000 MT on a vessel). Commercial terms typically specify sulphur content, viscosity at 50°C, flashpoint, and density. Payment is usually by MT103 SWIFT wire or confirmed letter of credit at sight. An independent inspection (SGS, Intertek, Bureau Veritas) at load port to verify quality against the agreed specification is standard practice.
