Refineries Brace for Q2 Impact: Oil Stock Losses & Negative Margins

Thansettakij•Economy•1d ago

Reader Briefing

Thai oil refineries are anticipating significant financial challenges in Q2 2026 due to potential stock losses and declining refining margins, following a volatile Q1 driven by geopolitical events.

•Thai oil refineries are at risk of experiencing losses in Q2 2026 due to falling oil prices and reduced refining margins.
•Geopolitical tensions in the Middle East and high crude oil prices in Q1 2026 led to record profits, but subsequent market adjustments pose a risk.
•Companies like Thai Oil are particularly vulnerable due to their large refining capacity and substantial oil reserves.
•Rising interest rates are increasing financial costs for refineries, further impacting profitability.

Overview

•Early 2026 saw significant volatility in Thailand's oil refinery sector due to Middle East geopolitical crises, driving crude oil prices above $100 per barrel.
•This led to historically high temporary profits in Q1, with crude prices exceeding $100 per barrel.
•Concerns are high for Q2 2026 regarding potential losses from oil stock and declining refining margins.
•Refiners face 'Stock Loss' by purchasing expensive crude oil only to see its market value decrease.
•Higher average inventory costs and a downward price adjustment even slightly below $100 per barrel will result in immediate recognition of stock value loss.
•Reduced demand for oil globally is narrowing the price gap between crude and refined products, affecting base refining margins (Market GRM).
•Increased working capital needs to procure and stock crude oil, coupled with high interest rates, are raising financial costs and eroding net profits.
•The Thai government's measures to control domestic retail fuel prices are reducing the margin refineries can earn from domestic sales compared to exports.
