Singapore’s average residual fuel oil stocks for October to date were 7% lower than in September, Enterprise Singapore’s latest data shows, according to a report published by reports on 18 October 2026.
The month‑to‑date figures show a fall of 1.39 million barrels in residual fuel oil, leaving inventories at 18.36 million barrels, while middle distillate stocks rose by 1.40 million barrels to 9.88 million barrels.
- Residual fuel oil: down 1.39 million bbls to 18.36 million bbls.
- Middle distillates: up 1.40 million bbls to 9.88 million bbls.
Stocks and movements
The decline in residual fuel oil is expressed as an average for October so far compared with the monthly average for September, as published by Enterprise Singapore and summarised in the reports item dated 18 October 2026. The data therefore captures early‑month flows rather than a complete October total.
Middle distillates moved in the opposite direction, recording an increase of 1.40 million barrels. The divergent movements mean overall refined product inventories in the Singapore system showed a mixed pattern during the period covered.
Trade flows
reports’s report notes the stocks fall for residual fuel oil occurred despite a rise in net imports, though the verification notes do not provide a numerical value for the net import change. The juxtaposition of lower stocks and higher net imports points to inventory drawdowns that have not been fully offset by inbound cargoes in the month to date.
Residual fuel oil is the principal feedstock for marine bunker fuel and is closely monitored by ship operators and traders for supply availability in the Singapore refining and storage hub. Middle distillates encompass products such as gasoil and diesel that supply both marine and land transport sectors, and the increase in those stocks suggests differing flows and storage priorities between product types during the early part of October.
Enterprise Singapore’s published monthly averages provide the basin‑level perspective used in the report. The figures cited describe changes in average inventory levels between the previous month and October so far, and should be read as month‑to‑date comparisons rather than final monthly tallies.
Market participants tracking regional fuel availability will watch subsequent data releases to see whether the residual fuel oil draw continues through the rest of October or if inbound flows and internal refinery activity restore stock levels. The mixed picture between heavy residuals and middle distillates underscores how product‑by‑product movements can diverge in the same reporting period.
For now, Enterprise Singapore’s data as reported on 18 October 2026 gives a snapshot of early‑October inventory dynamics in Singapore, showing lower average residual fuel oil stocks alongside a rise in middle distillates and an increase in net imports referenced in the report.
