At 7:56 PM on May 14, world oil prices simultaneously decreased. Accordingly, WTI oil price was at 100.48 USD/barrel, down 0.54 USD/barrel, equivalent to a decrease of 0.53%. Brent oil was at 104.92 USD/barrel, down 0.71 USD/barrel, equivalent to a decrease of 0.67%.
Oil prices fell on Thursday after Iranian state media reported that about 30 ships had passed through the Strait of Hormuz in recent hours, while the semi-official Fars news agency quoted a source as saying that Iran had begun to allow some Chinese ships to pass through.
According to the Ministry of Industry and Trade, the world gasoline and oil market in this operating period is affected by key factors such as: Information about the US and Iran towards a temporary agreement, reducing immediate tensions; some clashes still occur between the US and Iran; the Strait of Hormuz is largely still blockaded; the US Federal Reserve (Fed) may raise interest rates to curb inflation; military conflict between Russia and Ukraine is still taking place... The above factors have caused world finished gasoline and oil prices in recent days to increase and decrease depending on each item.
The average world finished petroleum product price between the price adjustment period on May 7, 2026 and the price adjustment period on May 14, 2026 is: 128.732 USD/barrel of RON92 gasoline used to blend E5RON92 gasoline (down 4.260 USD/barrel, equivalent to a decrease of 3.20%); 130.838 USD/barrel of RON95 gasoline (down 4.568 USD/barrel, equivalent to a decrease of 3.37%); 146.038 USD/barrel of diesel oil 0.05S (down 7.616 USD/barrel, equivalent to a decrease of 4.96%); 687.654 USD/ton of mazut oil 180CST 3.5S (down 25.816 USD/ton, equivalent to a decrease of 3.62%).
