World oil prices on July 30 slightly decreased after increasing in yesterday's session. However, world oil prices are still supported by US-Iran tensions, the risk of Middle East supply disruption and US crude oil inventories falling to their lowest level since 2018.
The world gasoline and oil market in this operating period is influenced by key factors such as: Conflict between the US and Iran temporarily cooled down but then showed signs of re-emerging; Iran continues to attack some ships passing through the Strait of Hormuz; military conflict shows signs of spreading in the Middle East region when the US, Saudi Arabia and armed groups in Iraq supported by Iran have mutual attacks; military conflict between Russia and Ukraine continues, focusing on energy facilities, oil refineries...
The above factors have caused world finished gasoline and oil prices in recent days to increase and decrease depending on the item.
