Thailand Power and Oil Market 2H 2026: In-depth Analysis of Investment Strategies Under Supply-Demand Changes

In the second half of 2026, the global energy market continues to seek balance between supply-demand imbalances and geopolitical risks. As an important energy consumer and producer in Southeast Asia, Thailand's power and oil market is experiencing unprecedented changes. This article will conduct an in-depth analysis of the current market situation, policy trends, and investment opportunities, providing comprehensive market forecasts and strategic recommendations for investors.

International Oil Price Fluctuations and Thailand Market Linkage Effects

Since July 2026, international oil prices have experienced significant fluctuations. Brent crude prices, under the dual impact of the hurricane season and OPEC+ production policy adjustments, once reached a high of $90 per barrel, then fell back to around $85 due to slowing global demand growth and increased inventories. These fluctuations have had a direct impact on Thailand's energy market.

As a net oil importer, every fluctuation in international oil prices is quickly transmitted to the domestic market. According to data from Thailand's Ministry of Energy, in the first half of 2026, the correlation between Thailand's gasoline prices and international oil prices reached 0.87, and diesel prices showed a correlation of 0.82. This high degree of linkage makes the performance of Thailand's energy stocks closely related to international oil price trends.

Notably, Thailand's sensitivity to international oil prices is changing. As Thailand accelerates its energy transition and increases the proportion of renewable energy, the impact of traditional oil and gas prices on the overall energy market is relatively weakened. However, in the next 3-5 years, oil products will still account for over 60% of Thailand's energy structure, and the impact of oil price fluctuations on the economy cannot be ignored.

Thailand Energy Policy Adjustments and Market Restructuring

In 2026, the Thai government continues to promote energy structure adjustments to achieve the 2030 carbon neutrality goal. The newly released "Thailand Energy Development Plan 2026-2030" clearly proposes to increase the proportion of renewable energy in the total energy structure from the current 20% to 30%, while reducing dependence on fossil fuels.

In the power and oil sector, policy adjustments are mainly manifested in three aspects:

\n
• Fuel Tax Reform: The Thai Ministry of Finance announced that it will gradually adjust the fuel tax structure, imposing higher taxes on high-pollution fuels while providing tax incentives for clean energy vehicles. This policy will affect fuel price structures and may lead some consumers to shift to electric vehicles.
\n
• LPG Market Liberalization: To promote competition and improve efficiency, the Thai Ministry of Energy announced that it will gradually liberalize the LPG market, allowing more private enterprises to enter this sector. Currently, PTT still controls about 70% of Thailand's LPG market, and market liberalization will bring a new competitive landscape.
\n
• Biofuel Promotion Plan: The Thai government is strengthening the promotion of biofuels, aiming to increase the blending ratio of bioethanol in gasoline from the current 10% to 15% by 2027, and biodiesel ratio from 7% to 10%.
\n

These policy adjustments will profoundly affect the supply-demand structure of Thailand's power and oil market. On one hand, the promotion of clean energy policies will reduce long-term demand for traditional oil and gas; on the other hand, during the transition period, oil and gas products will still be the mainstay of the energy structure, with stable market demand.

Performance of Major Energy Enterprises and Market Competition Landscape

Thailand's power and oil market is dominated by several major energy enterprises, with PTT Group as the national energy giant occupying a key position. In the first half of 2026, PTT Group achieved revenue of 1.2 trillion Thai baht, a year-on-year increase of 8.5%, but net profit only increased by 2.3%, reflecting the cost pressure and profit margin challenges facing the industry.

In terms of competitive landscape, Thailand's oil and gas market shows the following characteristics:

\n
• High Market Concentration: The top three energy enterprises (PTT, Bangchak, Esso) occupy about 75% of Thailand's oil and gas market, with market competition mainly concentrated among these major enterprises.
\n
• Obvious Gasoline Station Network Advantages: As of June 2026, there are about 15,000 gas stations nationwide in Thailand, with PTT-branded stations accounting for over 50%, forming a strong channel advantage.
\n
• Intensifying Upstream-Downstream Integration Trend: Major energy enterprises are strengthening upstream and downstream industry chain integration. In recent years, PTT has invested heavily in infrastructure such as LNG receiving terminals and refineries, aiming to increase industry chain control.
\n

Notably, as the energy transition accelerates, traditional energy enterprises are actively seeking business diversification. PTT Group has announced that it will invest 50 billion Thai baht in renewable energy projects in the next five years, aiming to increase the proportion of renewable energy business to 20% by 2030.
