The economy is picking up again worldwide, especially in China, and economic optimism has returned to the stock markets for a long time. Naturally, this is also having an impact on the oil price, which has been rising for weeks as a result. As oil is traded in US dollars on the global markets, prices for oil products such as diesel are rising sharply due to the strong dollar in Europe. The average price of crude oil in the Minerölwirtschaftsverband price index was €1.23 per litre in the months of March-April-May. It can be assumed that the BP Deepwater Horizon oil rig accident on 20 April will also have an impact on prices in the coming months.
