Bearish for Indian Refiners: Iran Conflict Drives Asian Margins Negative

Analyzing: Asian refining margins slip into negative territory as Iran war disrupts crude flows by et_companies · 18 Mar 2026, 2:27 PM IST (about 2 months ago)

What happened

Asian refining margins have sharply declined into negative territory, primarily due to crude supply disruptions stemming from the Iran conflict. This has led to surging freight costs for crude oil and forced refiners to cut operations, directly impacting their profitability.

Why it matters

This development is critical for the Indian stock market as Indian refiners are significant players in the Asian market. Negative refining margins directly erode their Gross Refining Margins (GRM), a key profitability metric. While crude prices might soften for consumers, the operational costs and reduced throughput will hit refiners' bottom lines.

Impact on Indian markets

Indian oil refining companies such as Reliance Industries (RELIANCE), Indian Oil Corporation (IOC), Bharat Petroleum Corporation (BPCL), and Hindustan Petroleum Corporation (HPCL) are likely to face significant negative impact. Their earnings from refining operations will be squeezed, potentially leading to downward revisions in their profit forecasts. This could trigger selling pressure on these stocks.

What traders should watch next

Traders should monitor the geopolitical situation in the Middle East for any de-escalation, which could ease crude supply concerns and freight costs. Also, watch for official statements from Indian refiners regarding their GRM outlook and any production cuts. Global crude oil price movements and demand indicators will also be crucial.

Key Evidence

  • Asian refining margins have turned negative.
  • The Iran conflict is disrupting crude oil supplies.
  • Refiners across the region are forced to reduce operations.
  • Benchmark Singapore gross refining margins have fallen sharply.
  • Freight costs have surged significantly, increasing landed cost of crude.
  • Demand is also showing signs of weakening.
