As of Aug. 03, the MABUX Market Differential Index (MDI), which monitors the spread between Market Bunker Prices (MBP) and the MABUX Digital Bunker Benchmark (DBP), indicated the following developments across the four major global bunkering hubs—Rotterdam, Singapore, Fujairah, and Houston:
• HSFO segment: Fujairah moved into the undercharge zone, making all four ports underpriced. Discount margins widened by $24 in Rotterdam, $12 in Singapore, $28 in Fujairah, and $15 in Houston. Rotterdam’s MDI exceeded the $100 threshold, while Houston stayed above it.
• VLSFO segment: Singapore, Fujairah, and Houston remained in the overpriced zone, although premium margins narrowed by $11, $32, and $14, respectively. Rotterdam continued to be the only underpriced port, with its discount widening by $14. Houston's MDI moved closer to the 100% correlation line between MBP and DBP.
• MGO LS segment: All four ports remained undervalued. Discount margins widened by $71 in Rotterdam, $31 in Singapore, and $56 in Fujairah, while narrowing by $30 in Houston. The MDI for Rotterdam, Singapore, and Fujairah remained comfortably above the $100 threshold, whereas Houston fell below this level.
