India's August CPI hits 4.82 percent as onions jump 48 percent

India's consumer price index rose 4.82 percent in August from a year earlier, up from 4.45 percent in July, according to provisional figures the Ministry of Statistics and Programme Implementation released on Monday. The print is the highest so far on the new CPI series that uses 2024 as the base year. Compared with the official back series it is the strongest reading since December 2024, when inflation was 5.22 percent. It is also the third month in a row above the Reserve Bank of India's 4 percent target midpoint.

Food did most of the work. The Consumer Food Price Index climbed to 5.95 percent from 5.52 percent in July. Rural food inflation was 6.13 percent. Urban food inflation was 5.64 percent. Onions jumped 48.27 percent year on year, up from 22.54 percent in July. Garlic rose 43.60 percent. Ginger rose 73.82 percent, a slowing from 83.57 percent but still a kitchen-level shock. Silver jewellery inflated 107.11 percent. Gold, diamond and platinum jewellery rose 35.53 percent.

Some items went the other way. Tomatoes were 31.09 percent cheaper than a year earlier. Potatoes were down 13.14 percent. Motor cars and jeeps were down 6.72 percent. Lady's finger was down 5.41 percent. Among broader groups, transport services for goods led at 14.64 percent. Food and beverage serving services rose 8.41 percent. Operation of personal transport equipment rose 7.40 percent. Paan and tobacco rose 7.34 percent. Purchase of vehicles fell 4.38 percent. Recreational durables fell 1.25 percent.

Rural headline inflation was 5.23 percent, urban 4.31 percent. The all-India CPI index stood at 108.74 against 107.95 in July. Rural CPI was 109.27. Urban CPI was 108.07. Core CPI, as calculated by CNBC-TV18 from the same release, rose to 4.2 percent from 3.9 percent. That is the sticky part. Food can move with a harvest. Core at 4.2 percent says services and other non-food items are not sitting still.

The path since spring is one direction. CPI was 3.93 percent in May, 4.38 percent in June, 4.45 percent in July and 4.82 percent in August. Each step has been small. Four steps put the new series through the RBI's preferred centre line and keep it there. Wholesale prices, released separately, printed 9.92 percent for August on the 2022-23 WPI series, with fuel and power at 22.93 percent. The two indices do not use the same basket. Together they say pipeline costs and kitchen costs are both rising into the Monetary Policy Committee's next meeting.

The MPC's job is a 4 percent target with a band of 2 to 6 percent. 4.82 percent is inside the band and above the bullseye. A 37 basis-point jump in one month on a new series is enough to argue against an easy cut and not enough, on its own, to argue for a hike. Markets will listen for whether the committee treats onions and ginger as weather or as a sign that food is embedding.

Households do not need the series number. They need the onion price. A move from 22 percent to 48 percent year on year on a staple that has no clean substitute is the political fact inside the statistical one. Tomatoes going the other way will not cancel it on a Delhi plate.

MoSPI labelled the release provisional, as it always does for the latest month. Revisions exist. They rarely erase a 37 basis-point step. The August file also confirms that the 2024-base series can print well above 4 percent. That was the open question when the series launched. It is no longer open.

What the committee does with 4.82 percent will be written in the next policy statement. What shops already did with onions, garlic and ginger is in the same table. The first is a rate. The second is a bill.
