Producer Price Index
A measure of prices at the producer level — what businesses receive for their output, before goods reach consumers.
In plain words
When a factory ships a box of goods to a wholesaler, the price it charges is captured by the Producer Price Index (PPI). When that wholesaler ships to a retailer, and when the retailer sells to you, those stages add distribution margins, retail markups, and taxes — which the Consumer Price Index (CPI) eventually captures. PPI sits earlier in the chain.
This earlier position makes PPI a leading indicator: if producer prices are rising today, consumer prices are likely to rise 1–3 months later (for goods) as the increase passes through the distribution chain. If producer prices are falling — as goods PPI did in late 2022 through 2024 — consumer goods prices tend to follow down, with a lag. This is why economists and analysts watch PPI releases closely ahead of CPI: they reveal what is coming down the pipeline.
In the United States, the Bureau of Labor Statistics publishes the PPI for Final Demand monthly, covering goods (~34% of the index) and services (~66%). The UK ONS publishes "Output PPI" and "Input PPI". Eurostat publishes "Producer Prices in Industry" for EU member states. The OECD compiles harmonised PPI data across member countries.
The pipeline: from crude materials to consumer prices
The BLS publishes three tiers of PPI that trace prices through the production chain:
A sharp move in crude materials PPI today is a signal to watch for final demand PPI in 1–3 months, and then CPI goods in a further 1–3 months. The total pipeline from crude materials to consumer prices can be 3–6 months. This is why the stage-of-processing tables in the BLS PPI release — not just the headline — are the most analytically useful part of the report. Our guide to reading a PPI report walks through these tables step by step.
PPI vs CPI: the key differences
The critical difference: PPI does not include rent (which is ~26% of US core CPI as Owners' Equivalent Rent) or the retail and distribution margins that add to consumer prices. This means PPI can fall sharply while core CPI stays elevated — as happened in 2023–24, when goods PPI turned negative but core goods CPI remained slightly positive as retailers rebuilt margins. See the PPI explainer for a full discussion of this divergence.
Limitations of PPI as a CPI predictor
Margin absorption: Retailers and wholesalers may absorb PPI changes rather than passing them through. When consumer demand is weak, businesses often compress margins to protect market share. This breaks the PPI-to-CPI link temporarily — and was a major reason why goods deflation in 2023–24 took longer than expected to appear in consumer prices.
Services PPI ≠ services CPI: Services PPI measures business-to-business service transactions — what one company charges another for logistics, consulting, or healthcare services. Services CPI measures what consumers pay for largely different services: rent, restaurant meals, personal care. The correlation exists but is loose and noisy. The dominant driver of services CPI is wage growth, not services PPI.
Imports not covered: PPI only covers domestically produced output. For economies with significant import exposure, imported inflation through import price indices matters independently of domestic PPI. The BLS publishes a separate Import Price Index to fill this gap. Our exchange rate and inflation guide explains how import prices interact with domestic PPI.
Frequently asked questions
Is PPI a reliable leading indicator for CPI?
For goods, yes — goods PPI leads core goods CPI by approximately 2–3 months with a partial pass-through of 30–50%. For services, the relationship is weaker and noisier because services PPI (business-to-business) measures different activities than services CPI (consumer-facing). The cleanest PPI-to-CPI signal is in the stage-of-processing series: rising intermediate goods PPI consistently precedes rising finished goods PPI, which then precedes consumer goods CPI. Use PPI alongside import prices, wage data, and shelter leading indicators for the most complete inflation forecast.
How is PPI different from the GDP deflator?
PPI measures prices received by domestic producers for final demand output — goods and services sold at the producer level. The GDP deflator measures the price change of all goods and services included in GDP, including government consumption and investment. PPI excludes imports (since imports are not domestic production); the GDP deflator also excludes imports but includes government spending and investment goods that may not appear in PPI. For inflation analysis, PPI is the better leading indicator for CPI. The GDP deflator is used for national accounts purposes (converting nominal to real GDP).
Where can I find PPI data for countries other than the US?
Eurostat publishes Producer Prices in Industry for EU/EEA countries at ec.europa.eu/eurostat. The UK ONS publishes "Producer Price Inflation" monthly at ons.gov.uk. The OECD compiles harmonised PPI data at stats.oecd.org under "Prices and Purchasing Power Parities > Producer Prices". For emerging markets, the IMF International Financial Statistics database (data.imf.org) has PPI series for many countries. Coverage and methodology vary more widely for non-OECD countries.
