On the last day of February, what was hitherto regarded as impossible, happened. What had been feared over decades but never materialised, the waterway that carries a fifth of the world’s crude oil, natural gas and LPG, closed. World crude prices surged within days, leaving every importing economy facing the same arithmetic. India imports more than 80 per cent of its crude and nearly 60 per cent of its cooking gas, most of it through that very strait, and the predictions wrote themselves: pumps would run dry within weeks, the cylinder would vanish from the kitchen and the economy would stall.
