Why Have Singapore Refining Margins Turned Negative and What Does It Mean for Oil Companies?
What Are Singapore GRMs?
Singapore GRM (Gross Refining Margin) is one of the most widely used global benchmarks to measure the profitability of oil refineries. It represents the difference between the price of refined petroleum products (such as petrol, diesel, jet fuel) and the cost of crude oil used to produce them.
In simple terms, it reflects how much profit a refinery earns from processing one barrel of crude oil into petroleum products.
When GRMs are high, refining companies earn better margins. When GRMs turn negative, it means refiners are effectively selling refined products at prices lower than the cost of crude oil used to produce them.

Why Singapore GRMs Matter Globally
Singapore is Asia’s largest refining and trading hub. Prices discovered in Singapore are used as a benchmark for refining margins across the Asia-Pacific region.
This is why Singapore GRMs are closely monitored by investors tracking refining companies such as:
🔻 Reliance Industries
🔻 MRPL (Mangalore Refinery)
🔻 Chennai Petroleum
If Singapore GRMs weaken sharply, it usually signals pressure on profitability for Asian refiners.
Why Have GRMs Turned Negative?
Singapore GRMs have reportedly dropped to around minus $11 per barrel, reflecting severe margin pressure for refiners.
The primary reasons include:
🔻 Sharp spike in crude oil prices due to West Asia geopolitical tensions.
🔻 Supply disruptions and risk premium added to crude prices.
🔻 Refined product prices (diesel, petrol, jet fuel) not rising at the same pace as crude.
🔻 Freight, insurance, and logistics costs rising due to regional conflict.
Is the Iran Conflict Responsible?
The ongoing conflict in West Asia has significantly contributed to the volatility.
When geopolitical tensions escalate near key oil transit routes such as the Strait of Hormuz, crude prices usually rise quickly due to supply fears.
However, refined product demand and pricing often adjust more slowly.
This creates a temporary mismatch where crude becomes expensive but refined product prices do not rise proportionately, compressing refining margins.
Which Stocks Could Be Impacted?
Negative GRMs can create short-term pressure on refining-focused companies.
Key stocks investors typically monitor include:
🔻 Reliance Industries (large integrated refinery)
🔻 MRPL
🔻 Chennai Petroleum
However, integrated companies with petrochemical businesses or diversified energy operations may be relatively more resilient than pure refining companies.
Investor Takeaway
The sharp fall in Singapore refining margins reflects the extreme volatility created by geopolitical tensions and crude price spikes. While negative GRMs are usually temporary, prolonged crude price rallies without corresponding increases in product prices can pressure refinery earnings in the near term. Investors should closely monitor crude movements, shipping disruptions, and refined product demand to assess how long the margin pressure may persist.
