The OPEC official also informed the EU that the present market volatility is caused by "non-fundamental issues" outside of OPEC's control and that it is the EU's job to advocate a "realistic" approach to the energy transition.

Oil and gas aren't the only commodities impacted by Ukraine's conflict. Russia and Ukraine produce almost one-third of the world's wheat exports, and both are big exporters of sunflower oil and fertilizer. As a result, food prices have reached historic highs, and several countries and non-governmental organizations are warning of impending food shortages.
