Brent crude has fallen to $73 a barrel, its lowest level since the U.S.-Iran war began on February 28, 2026, and is down 37% from its May 2026 peak of $115 a barrel. The drop helped lift India’s Nifty Auto index 2.2% in a single session, with several auto stocks rising 2%–3%. The report attributes the rally to easing diesel costs and lower total cost of ownership (TCO) for fleet operators as oil prices decline.
