BETWEEN, say December 25, 2019, and June 23, 2020, world crude (brent) oil prices have fallen by nearly 37 per cent. They had fallen by over 60 per cent between end-December and mid-April, but there has been some price-recovery since then; even so, the decline in world prices till June 23 has been quite dramatic. In India however, over this very period, petrol and diesel prices have been going up sharply and are now higher than ever before; in fact diesel prices have increased even more sharply than petrol prices and the difference between the two has largely disappeared.
