CNBC’s Jessica Ettinger highlights how record-high diesel prices are driving inflation across the economy. Guests explain that diesel is critical for transporting goods, agriculture, and mining, meaning higher costs ripple through the supply chain to raise consumer prices. The surge is driven by a severe shortage of refinery spare capacity due to geopolitical conflicts targeting facilities in the Middle East and Russia. Experts warn that these elevated energy costs will likely keep commodity and consumer prices high into next year.
