What This Indicator Measures
Daily FOB Singapore assessment of high-sulphur fuel oil with a maximum viscosity of 380 cSt, in USD/mt.
High Sulphur Fuel Oil (380 / 180 CST, 3.5%): A physical price for residual fuel oil with up to 3.5% sulphur. Asian and Gulf series are named by viscosity grade (380 or 180 cSt at 50 °C); European series are named by sulphur content (3.5%), with barge, cargo and delivered-bunker variants kept separate.
What the source does not state for this series
- The sulphur limit of the assessed grade is not printed in the loaded row; it is a high-sulphur grade by name only.
Specification · stated by the source for this series
- 380 CST = maximum kinematic viscosity 380 cSt at 50 °C (ISO 8217 residual grade), from the series name.
- 380 and 180 are maximum kinematic viscosity in cSt at 50 °C per ISO 8217 residual grades.
- 3.5% is the maximum sulphur content by mass.
Basis: FOB Singapore
- FOB (free on board): the price covers the product loaded on the vessel at the named origin; sea freight and insurance to the destination are excluded, so FOB values from different loading areas are not delivered-cost equivalents.
- Singapore is a port and storage hub at the southern tip of the Malay Peninsula; Asian refined-product cargoes are commonly priced against Singapore loadings.
Unit: USD/mt
- USD/bbl values (Singapore, Arab Gulf, Fujairah) and USD/mt values (Europe, Japan naphtha) cannot be compared without a product-specific density conversion; the site does not convert them.
- Published assessments are a low–high range with a midpoint; charts and monthly statistics use the midpoint only.
