Meanwhile, the Ministry of Energy reports on Thailand's energy situation and international context, reserve volumes, diesel sales, and the fuel fund status as of 17 April 2026.

Geopolitical tensions in the Middle East remain highly uncertain despite multiple diplomatic efforts, including planned second-round talks between the US and Iran via Pakistan, and US President Trump's announcement of a 10-day ceasefire between Israel and Lebanon. Simultaneously, the US expanded its naval blockade against Iranian ships and signaled possible financial sanctions if talks stall. These conflicting signals caused energy market volatility, with oil prices rising on 16 April 2026 due to supply concerns, then easing on the morning of 17 April following ceasefire news and renewed negotiation hopes.

WTI crude traded in the range of 92.90–93.68 USD/barrel, Brent at 97.94–98.67 USD/barrel, and Dubai steady at 105.51 USD/barrel. However, the market still faces risks from fuel shortages that peace agreements may not resolve immediately.
