Onshore fuel oil stocks fell by 2.85 million barrels, or about 448,000 tonnes, to a two-week low of 21.3 million barrels, or 3.35 million tonnes, according to Enterprise Singapore data.
The residual fuel stocks were on par with year-ago levels but were below the 2021 weekly average of 23.05 million barrels.
In the week to Sept. 8, fuel oil stockpiles jumped 17% to a seven-week high of 24.15 million barrels, or 3.8 million tonnes.
The latest inventories declines came despite a near threefold increase in Singapore's weekly net import volumes, which surged to a more than one-year high of 1.2 million tonnes. Weekly figures, however, are volatile.
By comparison, Singapore's weekly fuel oil net imports averaged 690,000 tonnes so far in 2021.
The largest net imports were from Malaysia at 264,400 tonnes, followed by the United Arab Emirates (UAE) at 264,000 tonnes and 148,000 tonnes each from Denmark and Malta.
Singapore fuel oil net imports from Denmark were at their highest in at least six years, or as far as available records go, while those from Malta and the UAE were at their highest since November 2018 and December 2019, respectively.
The top net export destinations for Singapore fuel oil were Bangladesh at 50,000 tonnes, followed by Thailand at 10,000 tonnes and Indonesia at 500 tonnes.
Fuel oil flows into East Asia, most of which come to Singapore, were expected between 4.5 million tonnes and 5 million tonnes in September compared with 4.75 million tonnes in August, according to Refinitiv Oil Research.
"The steady (to) higher inflows may alleviate ongoing supply tightness in Asia, with timespreads easing from week-ago levels," Refinitiv Oil Research said.
"Supply tightness for fuel oil is seen easing slightly due to dampening demand for Black Sea straight-run barrels by (U.S. Gulf) refineries, who are struggling to resume production in the aftermath of Hurricane Ida."
