• Prepared meals now classified under services, complicating CPI comparisons
• Effective food weight is closer to 40 percent when restaurant items are included

India’s new Consumer Price Index (CPI) series, set for release on February 12, is expected to show a lower food weight than the previous 2012 base series, but the exact magnitude depends largely on how food consumption is defined.

Official estimates indicate that food will account for roughly 37 percent of the CPI basket, down from about 46 percent earlier, reflecting rising incomes, diversification of consumption and a higher share of services in household spending.

However, this headline decline partly reflects a methodological shift rather than a purely structural change in consumption. A key adjustment is the relocation of cooked meals and snacks from the food category to a new restaurants and cafés services subgroup. While this classification better captures spending on eating out and services inflation, it complicates comparisons with the previous CPI basket.

A closer look: why the difference matters

Prepared meals and snacks carry a weight of about 3.3 percent of the inflation basket in the new series, higher than several traditional staples such as rice or electricity. In the 2012 CPI series, these items were included in the food index, with a slightly higher weight of about 3.6 percent. Their reclassification lowers the official food weight but does not necessarily reduce the role of food-related spending in household budgets.

When these restaurant-related food components are added back to the core food category for comparability, the effective food weight rises closer to around 40 percent rather than 37 percent. This suggests that the fall in food share is real but less dramatic than headline numbers imply.

A lower official food weight means food price shocks may have a somewhat smaller direct impact on headline inflation than in the past. However, if restaurant food inflation remains strong, its influence will still be felt indirectly through the services component.
