Why the RBI's Favourite Inflation Number Excludes Almost Everything That's Actually Rising

THE INFLATION NUMBER THAT STOPPED COUNTING WHAT'S ACTUALLY RISING

Headline CPI breached the RBI's own 4% target in June, at 4.38%. The RBI held rates anyway, calling the picture benign. That is only possible because the RBI is not really looking at headline CPI anymore - it is looking at a version of inflation with food, fuel and now precious metals stripped out, a metric currently sitting at 2.5%.

What Gets Excluded, And Why That's Not Automatically Wrong

Excluding food and fuel from core inflation is standard central-bank practice and for good reason: households don't stop eating or travelling when prices swing, so food and fuel prices are volatile but don't reveal much about underlying demand pressure that interest rates can actually influence.

Adding gold and silver to the exclusion list this year, given a global surge in precious metal prices, follows the same logic on paper. But logic that is sound in principle can still produce a misleading number in practice and that is exactly the economists' complaint: the RBI's chosen metric excludes precisely the categories driving 89% of CPI items to see price increases in June, then calls what remains "benign."

The Gap Between the Number and What It's Supposed to Measure

Core inflation excluding precious metals reads 2.5% year-on-year. But ANZ's economists pointed out that the month-on-month momentum in that same sub-basket, annualised, is already running at 4-4.4% - nearly double the headline figure the RBI is citing as reassuring.

A year-on-year average can look calm while the trend inside it is accelerating and that gap is exactly where a policy metric can mislead even when every individual number in it is accurate. The RBI's own projections make this starker still: it expects headline inflation to average 4.7% to 5.9% over the next several quarters, well above its 4% target, while describing the narrower core measure as on track to "align" with core inflation only by the end of the financial year.

Why This Is a Methodological Choice With Real Stakes This is not a

story about the RBI hiding bad news - every number here is disclosed and verified. It is a story about which number a rate-setting committee treats as decisive when headline and core diverge this sharply. If the RBI is, in practice, targeting a metric that excludes an ever-narrower slice of the CPI basket, then holding rates steady stops being a response to "benign inflation" and becomes a bet that the excluded categories won't feed back into the rest of the basket before the RBI's own more conventional core measure catches up.

For a GS3 aspirant, the transferable insight is this: inflation targeting frameworks are only as credible as the metric they actually target in practice, not the metric written into the statute. When a central bank's chosen indicator diverges this far from its legal mandate's headline number, the interesting exam question isn't whether the exclusion is theoretically justified - it's what happens to policy credibility if the excluded categories turn out not to be temporary after all.
