As of the week ending March 13, Singapore's light distillate inventories stood at 15.592 million barrels, at a low level for the same period over the past three years. This was mainly due to a significant increase in net exports from Singapore, driven by a surge in gasoline demand before the Holy Week in the Philippines. However, with the continuous rise in the penetration rate of new energy vehicles in Southeast Asia, Asian gasoline demand has been squeezed, showing an overall weak trend, and gasoline prices in Singapore have fallen.

As of the week ending March 13, Amsterdam-Rotterdam-Antwerp (ARA) gasoline inventories decreased by 8.5% to 1.51 million tons, mainly due to refineries gradually switching to summer gasoline production, with remaining winter inventories being sold off at reduced prices. This is part of the seasonal transition where refineries actively reduce their inventory. Market participants are relatively optimistic about the demand for summer gasoline.

As of March 7, U.S. gasoline inventories stood at 241.101 million barrels, a decrease of 2.32% from the previous week, marking the largest weekly decline since December 2024. The main reason is the increase in gasoline restocking demand ahead of the summer travel peak, which has boosted U.S. gasoline consumption. At the same time, refinery operating rates in the Gulf of Mexico region were suppressed by planned maintenance, with an average operating rate of 87.2% in March, below the seasonal average. Supported by the recovery in gasoline consumption and low refinery operating rates, U.S. gasoline inventories have declined.

Singapore light distillate inventories increased on a month-on-month basis, while gasoline inventories in Europe and America both declined. The expansion of trans-regional arbitrage between the US and Asia will stimulate an increase in the flow of gasoline resources from the Atlantic coast to Asia, but the rise in Suez Canal freight rates will suppress the outflow of gasoline resources. Under the continuous impact of increasing penetration of new energy, gasoline demand in Asia remains weak, dragging down Singapore's gasoline prices. In the first half of March, the monthly average duty-paid price of 92# gasoline in Singapore was 7,926 yuan/ton, a decrease of 439 yuan/ton or 5.25% compared to the previous month.

Three, domestic gasoline demand is weak, but high costs limit the decline in prices

In March, with no holidays to support, domestic gasoline demand was weak, and the middle and lower reaches mostly replenished stocks based on rigid demand, maintaining low inventory operations. At the same time, due to the high cost of procurement, the arbitrage space for moving northern gasoline to the south was slim or even inverted, which curbed the decline in domestic gasoline prices. In the first half of March, the average monthly tax-inclusive price of domestic gasoline exports reaching the shore was 8123 yuan/ton, a decrease of 212 yuan/ton from the previous month, a drop of 2.54%.

The decline in Singapore's gasoline prices is much greater than that of domestic gasoline, leading to an inverted export arbitrage for domestic gasoline.
