Trailing 3-month (T3M) bunker sales in Singapore fell to their lowest level in 14 months in June, according to preliminary estimates published by the Maritime and Port Authority of Singapore (MPA) and analysed by Bunker Index.

T3M volumes dipped 96,250 tonnes month on month (MoM) to 13.569m tonnes — the worst result since April 2025. This was despite monthly bunker sales in Singapore of 4.669m tonnes in June 2026, representing a rise of approximately 2.7% compared with 4,548m tonnes in May 2026 and a gain of around 1.6% against the 4,595m tonnes sold in the same month of 2025.

The month's uptick was driven in part by a recovery in marine fuel oil (MFO) volumes, which rose to 2.035m tonnes from 1.795m tonnes in May — an increase of roughly 13.4% month on month (MoM). Low-sulphur fuel oil (LSFO) remained the port's largest single fuel category by volume at 2.197m tonnes, though this represented a decline of approximately 4.2% compared with May's 2.295m tonnes.

Low-sulphur marine gas oil (LSMGO) sales came in at 343,200 tonnes in June, compared with 327,600 tonnes in May, while conventional marine gas oil (MGO) remained negligible at 1,900 tonnes.

Alternative and lower-emission fuels continued to register modest but measurable volumes. LNG bunkering reached 55,000 tonnes in June, down from 70,300 tonnes in May, while B100 deliveries fell sharply to 1,500 tonnes from 12,800 tonnes the previous month. Methanol recorded no sales during the month, as in May. Bio-blended LSFO totalled 30,700 tonnes, down from 36,400 tonnes in May, and bio-blended MFO came in at 5,300 tonnes against 11,600 tonnes previously.

On a year-to-date basis, Singapore's bunker sales for the first six months of 2026 totalled approximately 28.240m tonnes, compared with around 26.979m tonnes over the same period in 2025 — an increase of roughly 4.7%.

Meanwhile, trailing 12-month (TTM) bunker sales in June rose 74,410 tonnes MoM to 58.036m tonnes.
