May CPI Slows to 0.5% MoM, RBI Holds Tight

India's consumer price index rose 0.5% in May, a slight deceleration from April's 0.6% monthly gain. The headline hides a split: energy costs moderated, food prices didn't.

Food inflation, with a near 50% weight in the CPI basket, remains the Reserve Bank of India's biggest concern. Vegetable prices and edible oils have posted sticky gains in recent months. The RBI's monetary policy committee held the repo rate at 6.50% in early June and has said it will not cut until food price pressures ease.

Governor Shaktikanta Das has repeatedly flagged pass-through risk into broader inflation expectations. Services inflation, which the RBI tracks closely, has stayed elevated.

Fuel and light offered some relief. Global crude prices softened through April and May, feeding into domestic fuel indices. That tailwind is narrowing as base effects fade and crude stabilizes around $80 a barrel.

For bond markets, the 10-year yield has been rangebound since April. Without a shift in RBI communication or a drop in food inflation, that range holds. The central bank has been draining surplus liquidity via variable-rate reverse repo auctions, reinforcing its posture.

The next policy meeting is in August. The June and July CPI prints and the Union Budget due in July will shape the decision. Until then, the repo rate stays at 6.50%.

Sector readthrough: rate-sensitive sectors like banks and auto lenders will see limited relief on funding costs. Consumer staples firms with pricing power can pass through cost inflation. Margin compression is a risk for companies exposed to volatile food inputs.

The June CPI release is scheduled for July 12.
