Asian Refining Margins Dive Amid Iran Conflict Disruptions

As tensions in Iran disrupt crude supply chains, Asian refining margins have dropped sharply, forcing regional refiners to reduce operations. The conflict has severely impacted the critical Strait of Hormuz, causing feedstock shortages and an increase in freight costs, worsening the refining sector's profitability and economic stability across Asia.

In a significant blow to the refining sector, Asian refining margins have turned negative, following a brief upswing earlier this month. This downturn is largely attributed to disruptions in crude supply chains due to ongoing geopolitical tensions involving Iran, which have forced refiners across Asia to slash operating rates.

The benchmark Singapore gross refining margins (GRMs), crucial in assessing regional refining profitability, have plummeted from multi-year highs of USD 40-45 per barrel in early March to between negative USD 5 and negative USD 10 per barrel recently. This highlights a transition from supply-driven benefits to enduring structural challenges within the industry.

Dependence on oil and gas shipments through the Strait of Hormuz, a vital maritime corridor crippled by recent military strikes, has exacerbated feedstock shortages. As a result, refiners in Singapore and wider Asia are cutting back production, with freight costs surging as alternate, longer shipping routes are utilized, further pressuring the sector.
