The Isaias weather system is approaching, and the price of crude oil has risen by about 70%. On October 9, 2026, around 70% of the crude oil production in the US waters was halted due to Isaias, which was heading towards the southern Gulf of Mexico. The halt of such a large number of productions is expected to cause Brent and WTI prices to rise. Additionally, China's decision to resume the supply of restricted fuels after a brief interruption during its Golden Week period contributed to an upward trend in oil prices. Reuters reported that Chinese authorities have declared that they would resume the supply of restricted fuels, essential for maintaining global energy supply stability. The ground situation was further aggravated by ongoing tensions between Iran and the United States.

The Trump administration's statement regarding the productive talks with Iran concerning the war in the Middle East has led to a decrease in oil prices before the session. However, these talks were not expected to bring about immediate changes in the geopolitical scene. The conflict between Russia and Ukraine has also interrupted the delivery of limited fuels such as gasoline, drinking water, and especially diesel. These interruptions have added to the volatility of the oil market, making it even more difficult to predict future trends for the past. The presence of Isaias in the Gulf of Mexico has caused approximately 1.3 million barrels per day to be stopped, or roughly 62.9% of the current crude production.

This stop has increased global oil market pressure, leading to price increases. As Typhoon Isaias approaches, there are growing concerns about the potential effects on corporate operations and market trends. The confusion surrounding Typhoon Isaias and the extent of damage it could cause adds another layer of complexity to the already volatile market scene. Despite recent positive impacts on oil prices, analysts remain cautious, observing that the market remains highly sensitive to geopolitical events and natural disasters. They anticipate that crude oil prices will continue to rise, potentially reaching new levels.
