This calls into question RBI‘s assessment that episodic spikes in food inflation, unless very frequent, do not require a deviation from its monetary-tightening trajectory. Segregating the supply-and-demand side effects of inflation allows it to steer the economy to a soft landing. The evidence is softening core inflation – which factors out volatile food and energy prices – although it is still a percentage point above the 4% target set out for inflation based on CPI. Ancillary evidence is provided by WPI with a bigger weight to manufacturing, which is on a deflationary course.
Yet, if food inflation is neither as idiosyncratic nor as easily amenable to supply-side measures that the central bank’s rate-setting committee assumes, the shape of the interest-rate upcycle could become significantly different. Persistent food inflation imposes an extra onus on monetary demand compression. A faster reduction in core inflation builds a bigger cushion against recurrent surges in food inflation.
