The price of oil (expressed in US dollars) can rise in two ways. 

The price may rise if oil rises in price, and may rise if the US dollar depreciates. 

What are the prerequisites for an increase in oil prices? 

This is her deficiency.  An embargo on Russian oil could potentially lead to a shortage. 

What are the prerequisites for the depreciation of the US dollar? 

The US dollar is the world's reserve currency.  However, at present, Russia and China are refusing to use the US dollar in their financial and economic activities.  Recently I read the news that Saudi Arabia plans to sell oil not for US dollars, but for Chinese yuan.  This is a very negative signal for the US dollar. 

Therefore, based on this, there are serious prerequisites for further growth in oil prices.
