SINGAPORE: Supported by shrinking supplies and firm demand, Asian refiners’ profit from producing very low sulphur fuel oil (VLSFO) rose to a one-year high this week, setting the stage for a trend that could persist throughout the year, traders and analysts said.

“Tightness in the fuel oil complex will remain a common theme through 2021, especially as the tightness in crude ensures that any uptick in margins will be transferred straight to crude producers if OPEC+ producers can hold their nerve,” said Energy Aspects in a note to clients last week.

The front-month VLSFO margin was at $15 per barrel above Dubai crude on Tuesday, its highest since Feb. 20 and up from $11.75 a barrel at the start of the year, according to Refinitiv data in Eikon. VLSFO refining margins have spiked this week “amid tightness in the Asian market,” said Sri Paravaikkarasu, director for Asia oil at FGE.

“In fact, offshore VLSFO inventories in Singapore dropped to a record low of 10.7 million barrels,” said Paravaikkarasu. The recent gains in refining margins for VLSFO, used in marine fuels, known as bunker fuel, and as a feedstock in power generation, occurred as crude oil prices soared to a 13-month high this week. Prices gained as investors are betting that fuel demand will rise while the Organization of the Petroleum Exporting Countries (OPEC) and its allies, known as OPEC+, keep a lid on supply.

VLSFO margins have been supported by resilient bunkering demand, which is already back to pre-pandemic levels in most ports around the world, as well as a spike in demand from utilities earlier this year as they faced liquefied natural gas shortages.

Fuel oil flows into east Asia, most of which comes to the Singapore trading and storage hub, were assessed at 4.5 million to 5.5 million tonnes in February, down from 5.63 million tonnes in January, according to Refinitiv Oil Research.

While rising prices could prompt producers to increase output of the fuel over the near term, sustained refinery production cuts and resilient demand could keep VLSFO prices supported throughout the year, said three traders involved in the fuel oil market. “We should see incremental VLSFO volumes from the Middle East arriving in Asia this month. This will coincide with a seasonal pullback in Asian bunker demand (from March) and lower (low-sulphur fuel oil) needs from Northeast Asian power producers,” said Paravaikkarasu.
