Onion Prices Surge 116% in October, Push India's Retail Inflation Above RBI's 6% Limit

India’s retail inflation climbed to 6.09% in October on a year-on-year basis, breaching the Reserve Bank of India’s upper tolerance threshold for the first time in two years, data released by the Ministry of Statistics on Thursday revealed.

Measured under the new Consumer Price Index (CPI) series, the sharp uptick in headline prices was driven primarily by surging kitchen essentials and precious metals. With retail inflation crossing the central bank’s mandated comfort band of 2 to 6%, expectations of another interest rate hike at the upcoming monetary policy review have intensified.

Kitchen Staples and Silver Drive Price Surge

Overall food inflation accelerated to 8.94% in October, putting direct pressure on household budgets across the country. Onion prices registered the steepest climb, skyrocketing by 116.22% compared to October last year.

Garlic followed closely, turning costlier by 60.74%. Ginger and lemon prices also recorded substantial year-on-year jumps of 48.32% and 47.30%, respectively. Outside the food basket, silver jewellery emerged as one of the top inflation drivers, with prices surging by 52.39% during the month.

A few essential commodities offered marginal relief to consumers. Potato prices declined by 14.24%, while cauliflower and coconut became cheaper by 10.57% and 5.6%, respectively, over the same period last year.

Central Bank Policy and Rate Hike Expectations

The breach of the 6% ceiling complicates the RBI's mandate to balance economic growth with price stability. On October 7, the Monetary Policy Committee (MPC) voted unanimously to raise the policy repo rate by 25 basis points to 5.5%, aligning with a broader global shift toward hawkish monetary policy following a 25-basis-point rate hike by the US Federal Reserve in September.

In his October 7 monetary policy statement, RBI Governor Sanjay Malhotra noted that CPI inflation had already begun edging upward earlier in the fiscal year, rising from 4.5% in July to 4.8% in August 2026. While food and fuel groups accounted for most of that climb—driven by spikes in sugar and onion prices alongside unfavourable base effects in fuel—core inflation also rose to 4.2% in August. Excluding precious metals, core inflation stood at 2.9%, while the weighted share of CPI items recording inflation above 4% grew steadily to roughly 37%.

Supply-Side Pressures Cloud Near-Term Outlook

Looking ahead, inflation faces persistent supply-side risks stemming from a deficient monsoon, ongoing El Nino conditions, and elevated energy and commodity costs whose pass-through to consumers remains incomplete.

Factoring in these pressures, the central bank projected CPI inflation at 5.2% for the 2026-27 financial year, with quarterly estimates pegged at 4.9% for Q2, 6.0% for Q3, and 5.7% for Q4. Inflation for the first quarter of 2027-28 is forecast at 5.6% with evenly balanced risks, while core inflation for 2026-27 is projected at 4.4%.
