The instrument problem

A WPI and a PPI are not the same measurement, and only one of them is common.

India is unusual. Its headline producer-side inflation number is a Wholesale Price Index — the price of goods changing hands at the wholesale stage, imports included, services excluded entirely. Most comparable economies retired that instrument decades ago in favour of a Producer Price Index, which measures the prices producers receive for their own output, excludes imports, and in several countries now includes services.

The two answer different questions. A WPI moves when the price of an imported barrel moves; a domestic-output PPI does not, at least not directly. For an economy importing over 85% of its crude, that distinction is not a footnote — it is most of the difference between the two series in any year when energy moves.

Japan makes the point neatly: what it now calls the Corporate Goods Price Index was called a wholesale price index until it was renamed and reworked in 2002. The instrument India still leads with is the one most of its peers replaced.

The wedge

Producer prices overshoot, then undershoot. Everywhere.

Read across and the same story appears five times out of seven. Producer-side prices were below consumer inflation before the pandemic, overshot it hugely in 2021–22, and fell below again from 2023. The turn is not an Indian phenomenon, an American one or a European one. It is what a global commodity and freight shock does to the two ends of a price chain, and it happened on roughly the same schedule in India, the United States, Japan, Korea and the euro area. Japan is a partial exception in timing: it peaked lower, at 9.8%, and stayed positive through 2023 rather than turning negative.

Brazil is not a partial exception. It ran a different cycle. Its producer prices rose 11.1% in 2020, the year every other economy here was flat or falling, and peaked at +31.6% in 2021 — earlier and roughly twice as high as anyone else. That is not the commodity shock, which had not arrived; it is the real, which lost about a quarter of its value against the dollar during 2020. A producer price index in a country with a collapsing currency and a heavy imported-input bill measures the exchange rate as much as it measures prices. Brazil then fell hardest too, to −6.2% in 2023.

China is the other exception, in the opposite direction. It is the only economy here with producer prices falling in two consecutive years — −3.0% in 2023 and −2.2% in 2024 — and its 2021 peak of +8.1% was among the mildest. Set that against its consumer inflation of 0.2%, 0.2% and 0.0% over 2023–25 and the picture is consistent at both ends of the chain: China is the one large economy in this comparison that did not have an inflation problem to solve, and now has the opposite one. Where Brazil’s deviation is a currency story, China’s is a demand story.

So the synchronised turn is real but it is not universal, and the exception is instructive: it appears exactly where a large currency move sits on top of the commodity cycle. Any account of 2021–22 producer inflation that does not separate the two will misread Brazil completely and will slightly misread everyone else.

What differs is amplitude. India’s wholesale inflation swung 16.2 percentage points between 2022 and 2023, from +15.4% to −0.8%. The euro area swung 27.3 points, from +26.0% to −1.3% — the violence of a gas shock passing through an industrial base. The United States peaked earliest, in 2021 rather than 2022. Japan and Korea barely swung at all — Japan from +9.8% to +4.4% and Korea from +8.4% to +1.6%, neither going below zero. Both are heavy importers of energy that hedge and contract forward; neither had much domestic inflation to begin with.

The lesson this blog drew from the Indian series holds across all seven and gets stronger: a producer-side index is not a slower version of the consumer index. It is a different variable with its own amplitude, and averaging across the turn destroys the information in both.

Where India sits on consumer prices

Near the bottom of the G20, which is new.

In 2019 India had the highest consumer inflation of any major economy in this table outside Argentina. By 2025 it is at 2.4% — below Brazil, Mexico, South Africa, Japan and Korea, and below the last published American figure. That is a genuine and underdiscussed reversal, and it happened while the wholesale series was doing something completely different.

Two economies are worth naming for the opposite reason. China printed 0.0% in 2025 after 0.2% in each of the two preceding years — consumer prices flat for three years running. Japan is the only advanced economy in the table whose inflation is higher now than during the 2022 shock, at 3.2% against 2.5%: the exit from deflation arrived late and has not reversed.

The comparison that no longer exists

The harmonised producer series was retired, and nothing replaced it.

This piece was supposed to cover more countries. It does not, and the reason is a finding in itself.

Until 2022 the OECD published a harmonised family of wholesale and producer price series covering its members and major partners, India included — the series that made a genuine like-for-like international comparison possible. It was discontinued. On the public data mirrors, every one of those series stops in 2022: India’s wholesale aggregate at December 2022, Japan’s producer indices at April 2022, China’s and the euro area’s at December 2022. The OECD’s current price database is extensive and live, and contains no producer price data at all — consumer indices, harmonised consumer indices, house prices and purchasing power parities, and nothing on the producer side.

China had to be reached the long way round. The National Bureau of Statistics data portal returns 403 Forbidden to requests from an Indian IP and its main site does not respond at all from here; the OECD mirror stops in December 2022 with the rest. The figures in Exhibit 1 therefore come from the NBS’s own Statistical Communiqué on National Economic and Social Development, one per year, retrieved from the Internet Archive. That is the Bureau’s own published text, archived — not a redistributor’s reconstruction — and each figure is the sentence “the producer prices for industrial products went down/up by X percent” read directly out of the release. Four of the six were cross-checked against the OECD mirror where the years overlap and agree exactly.

Two limits follow from the route. China’s 2025 figure is missing because the communiqué covering it would have been published in February 2026 and the Archive has no capture of it — the site went dark to crawlers at roughly the point it went dark to us. And China is absent from the monthly 2026 panel entirely, because monthly releases are not archived at all. An annual series recovered from archived press releases is a weaker instrument than a live API, and it is labelled as such here rather than quietly mixed in.

So the seven-economy panel in Exhibit 1 is not a choice of scope. It is what can still be assembled, one national statistical office at a time, with the differences in instrument stated rather than smoothed over. Anyone presenting a tidy ten-country wholesale-price chart for the last three years is either using a vendor’s reconstruction or has not checked where the numbers stop.

A companion piece, Inflation Trends Globally: What Five Years Actually Cost, takes the same data from the other direction — global first, with the full G20 consumer panel and Argentina included for scale. This article is the India-anchored reading and the methodology argument.

The whole episode in one number

Five years of inflation, compounded.

Year-on-year rates are how prices are reported and a poor way to feel their weight. Compounding 2021 through 2025 gives the question most people actually mean when they ask what has happened to prices.

The spread is the point. Over five years Brazil’s producer prices rose almost half and China’s rose under 7% — and China’s figure covers four years, so the true five-year gap is wider still. Two large emerging economies, the same window, a sevenfold difference in outcome.

India sits in the middle of both columns. Wholesale prices up 29.4%, consumer prices up 27.4% — over a quarter added to the price level in five years, or 5.0% a year at the till. Applying the rule of 72 used in the earlier wholesale piece, 72 ÷ 5.0 puts an Indian consumer doubling at about 14 years on the pace of the last five — faster than the fourteen-year record implies, and worth holding against the low 2.4% print for 2025.

The 2.0-point gap between India’s producer and consumer totals is the narrowest of the four economies where both sides can be measured over a matched window — Japan’s is 15.0 points, Brazil’s 13.2, and the United States’ 9.8 when producer and consumer are both cut to 2020–24. Whatever the 2021–22 wholesale spike did in India, it did not durably open a wedge between what producers paid and what households paid. It arrived, and it was absorbed.

Reading the Indian prints against this

Three things the international view changes.

The 2022 wholesale spike was not an Indian policy failure. It was smaller than the euro area’s and arrived at roughly the same time as everyone else’s. Explanations reaching for domestic causes have to explain why the same shape appears in economies with entirely different domestic policy.

The current divergence is the unusual part. India’s wholesale inflation has run near zero for three years — −0.8%, +1.2%, +0.9% — while consumer inflation fell steadily from 5.6% to 2.4%. Both falling is normal; both being this low simultaneously, in an economy growing at 6–7%, is not the configuration of the 2010s.

And 2026 is another synchronised turn, not an Indian one. India’s April 2026 wholesale inflation came in at +8.3%, the sharpest since 2022. So did everyone else’s:

The United States went from +2.4% in January to +12.3% in May — a ten-point acceleration in four months, larger and faster than India’s. Korea moved almost identically, +1.9% to +8.6%. Japan more than doubled, from +2.9% in March to +7.1% in June, after two years of easing. The euro area crossed from −2.7% to +4.9% inside three months. India’s April print of +8.3% sits between Korea and the United States.

Brazil is the laggard this time, and by the same logic as before: it entered 2026 at −4.4%, still working off the 2021 spike, and has only just crossed into positive territory at +2.5%. The country that led the last cycle is trailing this one.

Whatever is driving the 2026 producer-side turn — crude moving from roughly $77 to $92 over the period (Brent spot price, EIA, January to June 2026) is the obvious candidate — it is not something happening only to India. An explanation reaching for Indian fuel taxation has to account for the American number being larger and the Korean one being the same.
