Commodity Market Volatility

Commodity prices have been rising since, i think, late 20 20 and then have sky rocketed in recent weeks. As many as 25 african countries, including many least developed countries, import more than one third of their wheat from the two countries at war. But those sky rocketing commodity prices aren't just a matter of disrupted supply and too much demand. What role have invest s taking what are called long positions on commodities, meaning that they purchase derivatives, betting that prices will rise?
