Why inflation looks better after 2014

The measured gap

7.98% → 4.83%

Average annual consumer price inflation, UPA (2004–13) against NDA (2014–26), computed from the same dataset as every other figure on this site. Lower is better, so this is the one cross-era measure on which the later period performs better.

Reason 1  ·  This is the largest single factor.

The comparison straddles the collapse of a global oil cycle

Brent crude fell from about $115 a barrel in June 2014 to below $30 by January 2016, roughly 75% in nineteen months. The cause was entirely outside India. United States shale supply arrived at scale, and OPEC decided to defend market share instead of cutting production to hold the price up.

India imports about 88% of the crude it consumes (88.2% in 2024-25, provisional, according to the Petroleum Planning and Analysis Cell). Energy prices enter the consumer price index directly through fuel and light, and indirectly through the transport cost of everything else. A 75% fall in the landed price of the most import-dependent input in the economy is a large tailwind.

The timing matters most. The shock arrives almost exactly at the boundary between the two periods being compared. Any measure that is sensitive to world energy prices will show a break at 2014 whether or not anything changed in Delhi. The same channel ran the other way in 2026. Crude prices rose sharply after February, and in late March 2026 the government cut the special additional excise duty on petrol and diesel to cushion the shock (Notification 05/2026-Central Excise, 26 March 2026; ₹10 a litre by the government's own announcement).

Reason 2  ·  This one runs against the government, and it is the part most often left out.

The government captured much of the fall instead of passing it through

Central excise duty on petrol was ₹9.48 a litre and on diesel ₹3.56 a litre in 2014. Between November 2014 and January 2016 it was raised on nine separate occasions, by ₹11.77 a litre on petrol and ₹13.47 on diesel. The stated purpose was to absorb the gains from falling global prices into the exchequer and keep them from reaching the pump.

Two things follow. First, the disinflation that households actually experienced was the residual left after the tax take, so the fall in measured CPI understates how large the imported price shock was. Second, and more awkwardly for anyone claiming credit, to the extent that policy acted on fuel prices in this period, it acted to keep them higher than the world price would have delivered.

The tax take has kept moving since. Central excise on petrol was raised by ₹2 a litre in April 2025 and cut in late March 2026 during the West Asia oil shock, by ₹10 a litre according to the government's announcement (Notification 05/2026-Central Excise). The rates were revised again in July 2026. Fuel tax is a policy choice with a fiscal rationale, and it can be defended. It cannot be evidence of an anti-inflation achievement.

Reason 3  ·  Symmetrical to the first point, and just as important.

The UPA average sits on top of a global commodity boom

The comparison has two ends, and the earlier one is not a neutral baseline. The UPA's second term coincided with the 2008 food and fuel price spike, the commodity boom that ran through 2013, and the worldwide fiscal and monetary stimulus that followed the financial crisis. Indian inflation ran at 10.9% in 2009, 12.0% in 2010 and 10.0% in 2013 on the World Bank series.

Setting an era containing a commodity boom against an era containing its collapse produces a difference. Most of that difference reflects world prices across two adjacent decades, and only part of it reflects the two governments.

Reason 4  ·  The strongest policy candidate.

Where domestic policy did contribute, the mechanism supports this project's thesis

India did adopt formal inflation targeting in this period, and it is a real institutional change. The Monetary Policy Framework Agreement between the government and the Reserve Bank was signed on 20 February 2015. The Finance Act 2016 amended the Reserve Bank of India Act 1934 to give it statutory backing and to create a Monetary Policy Committee, which was constituted in September 2016. The target is 4% consumer price inflation with a tolerance band of two percentage points either side.

There is a reasonable case that this anchored expectations and contributed to the outcome. We do not dismiss it. Consider, though, what kind of thing it is. Inflation targeting is a rule that binds the executive. It moves an instrument out of the discretionary reach of whichever government holds office, hands it to a committee with a published mandate, and requires the Reserve Bank to send a report to the Central Government under section 45ZN of the RBI Act when the target is missed.

So if this is the channel, the finding is that India's best macroeconomic outcome in the period came from deliberately constraining executive discretion. That is the argument this project makes everywhere else, and this is an instance of it.

Reason 5  ·  Narrow, but it affects the most-quoted number.

The 2026 figure is not on the same basis as the rest of the series

From the January 2026 print, published on 12 February 2026, the Ministry of Statistics replaced the CPI series based on 2012=100 with one based on 2024=100. The new series draws its weights from the Household Consumption Expenditure Survey 2023-24 and adopts the COICOP 2018 classification in place of the older six-group structure.

Food's weight in the basket falls from 45.86% to 36.75%. The same movement in food prices now produces a smaller movement in headline CPI than it would have under the old series. Indian consumption patterns did change between 2012 and 2024, and reweighting was overdue, so this is no manipulation. It does mean the 2026 figure and the 2014-2025 figures are measured on different rulers, and this site labels the 2026 figure as such and does not splice the two silently.

Reason 6  ·  Stated as a limitation. It is not a finding.

A headline average is not what a household experiences

A single national CPI average conceals distribution. A household spending most of its income on food faces something much closer to food inflation than to the headline, and the reweighting described above mechanically reduces how much food shows up in the headline for everyone.

We flag this because it is true and because readers raise it. This project has not measured it. Establishing what inflation different income deciles actually faced over 2004-2026 would require expenditure-weighted price indices by decile, which is a substantial piece of work that has not been done here. Treat this section as a caveat on the headline.

Argued against ourselves

The strongest case against this page

The best version of the counter-argument runs like this. Oil fell for everyone, yet not every oil-importing economy brought inflation from double digits to the low single digits and held it there for a decade. Something domestic must have done work. Inflation targeting is the obvious candidate, and there were others. Food-price management improved, buffer stock operations were more competent, and the fiscal deficit was consolidated between 2014 and 2018.

We think that case has force, and we have not refuted it. Our claim is narrower, and we think it is defensible. The raw cross-era gap cannot be read as a policy result, because a shock large enough to explain most of it arrived at exactly the era boundary. And the leading domestic candidate is a constraint on executive power.

Falsification

What would change our reading

A measure of core inflation (excluding food and fuel) showing a fall of comparable size across the two eras would be strong evidence that something other than the commodity cycle was operating, because it strips out the channel the oil shock runs through. This project does not currently carry a consistent core series back to 2004, so it cannot make that test, and it does not claim the test has been run.

Comparative evidence would also move us. If India's disinflation is materially larger than that of other oil-importing emerging economies over the same window, the residual needs a domestic explanation.

If either analysis is published and points the other way, it will be recorded on the updates page and this page will be rewritten. That is the standing commitment on everything here.

In one paragraph

Inflation is lower under the NDA. This site reports that plainly, counts it as the one measure on which the period performs better, and declines to award credit for it. Our reading, which the core-inflation test described above has not yet checked, is that most of the gap comes from the world oil price arriving at a convenient moment. Policy taxed the part of the windfall it touched. The domestic institution with the best claim to have helped works by taking discretion away from government.
