2026-06-18MABUX: Bunker market to continue downward movement on Jun. 18 following U.S.–Iran peace agreement.
The MABUX World Bunker Index — a composite benchmark reflecting daily prices for 380 HSFO, VLSFO, and MGO — continued its downward trend on Jun. 17, marking the fourth consecutive day of declines.
380 HSFO: USD/MT: 610.03 (-19.61)
VLSFO: USD/MT 760.04 (-26.66)
MGO: USD/MT 1 124.98 (-22.75)
Prices remain under pressure, while physical premiums continue to be supported by tight prompt availability across key supply hubs. The next major catalyst for the market will be the anticipated signing of the US-Iran agreement on Jun. 19. Equally important will be the extent to which the agreement translates into a normalization of cargo movements and bunker fuel supply flows. Any tangible improvement in physical availability could accelerate the easing of premiums, while delays or disruptions may continue to support the current supply-driven price structure.
As of Jun. 17, the MABUX Market Differential Index (MDI), which measures the spread between Market Bunker Prices (MBP) and the MABUX Digital Bunker Benchmark (DBP) — registered the following dynamics across the four major global bunkering hubs: Rotterdam, Singapore, Fujairah, and Houston:
• HSFO segment: Rotterdam, Singapore, and Houston remained undervalued relative to the MABUX benchmark. The degree of undervaluation narrowed by 22 in Rotterdam and $ 5 in Houston, but widened by $23 in Singapore. Fujairah remained the sole overvalued port in the HSFO segment, with its premium declining by $10. Singapore's MDI exceeded the $100 threshold.
• VLSFO segment: The undervaluation trend persisted in Rotterdam, Singapore, and Houston. The discount decreased by $20 in Rotterdam, $2 in Singapore, and $1 in Houston. Fujairah remained the only overvalued hub, with its premium increasing further by a further $22 and staying well above the $100 threshold.
• MGO LS segment: Fujairah also remained the only overvalued port in the MGO LS segment, despite its premium declining by $13. Rotterdam, Singapore, and Houston continued to be undervalued. The degree of undervaluation widened by $4 in Rotterdam, $9 in Singapore, and $17 in Houston. MDI values in Rotterdam, Singapore, and Fujairah remained well above the $100 threshold.
MABUX expects global bunker indices to maintain their downward trend on Jun. 18 as the United States and Iran sign a peace agreement, easing concerns over potential supply disruptions in the Middle East: minus 5-20 USD/MT, VLSFO: minus 5–20 USD/MT, MGO LS: minus 10–30 USD/MT.
