The difference is, this time no one—economists, political scientists, the Reserve Bank of India, not even the government’s economic advisors—seems to agree on what will slow the steady upward march of prices, or when. Last week, the central bank hiked, for the 12th time since March 2010, the interest rate at which it lends to other banks. This has been the key response against inflation till date, and is often described as a “textbook case” of trying to dampen demand through monetary policy. If demand is successfully lowered, it is expected, any escalation in prices caused by supply constraints will be curbed.
