Financial market impact of the COVID-19 pandemic
Economic turmoil associated with the COVID-19 pandemic has had wide-ranging and severe impacts upon financial markets, including stock, bond, and commodity (including crude oil and gold) markets. Major events included a described Russia–Saudi Arabia oil price war, which after failing to reach an OPEC+ agreement resulted in a collapse of crude oil prices and a stock market crash in March 2020.
