Producer Price Index
CPI's upstream: factory-gate prices move first and retail prices follow — PPI is the forward sentry of the inflation chain.
Monthly (8:30 AM ET, mid-month)
What it is
The Producer Price Index (PPI), published by the BLS, measures monthly changes in domestic producers' selling prices — covering goods at the factory gate and, since its expansion, trade services and portions of services (transportation/warehousing, wholesale). The core measure excludes food and energy. PPI's distinctive position is upstream: business costs lead retail prices, so its trend and components (especially trade/transport services) serve as inputs for forecasting CPI and PCE — even though the two "baskets" do not coincide.
Release schedule
| Item | Details |
|---|---|
| • | Frequency: monthly (covering the prior month) |
| • | Release: mid-month at 08:30 ET (21:30/22:30 Beijing time, DST-dependent), usually a day or two after CPI |
| • | Contents: headline PPI m/m and y/y, core PPI (ex food & energy), goods and services components |
| • | Frame evolution: expanded from goods-only factory prices to include trade services and transport/warehousing |
| • | Release pairing: ships in CPI week (typically one day apart) — the "inflation week" double print |
Why it matters
Three layers of value: forward guidance — factory-gate to retail pass-through runs roughly a quarter behind, so PPI components (especially those mapping to PCE healthcare/financial services) inform next month's CPI/PCE forecasts; structure — core PPI's trend evidences non-energy business cost pressure upstream of sticky inflation; and event weight — sharing CPI week amplifies its role in positioning, where a PPI surprise reshapes readiness for the CPI print.
Impact across assets
Typical impacts (using an upside surprise):
| Asset | Typical impact |
|---|---|
| US equities | Hot → upstream stickiness evidence → rate expectations up → pressured; cooling → eases the "cost vs pricing" worry |
| US Dollar Index | Hot → firmer (hawkish repricing); cooling → softer — elasticity usually below CPI's |
| Gold | Hot → short-term pressure; but a cost-push inflation regime supports gold's long-run hedge narrative |
| Crypto | Tracks rate expectations: hot → tighter liquidity pricing → pressured |
| Treasuries | Hot → yields up; core PPI's trend matters more for inflation-compensation pricing than any single pulse |
How to read it
The standard read:
| Dimension | How to read it |
|---|---|
| Core PPI trend | The ex-food-energy trend is the starting point for stickiness — 3/6-month annualized beats any single month |
| Services components | Trade and transport/warehousing swings track fuel and logistics costs — their mapping to PCE is more direct than goods |
| Divergence from CPI | PPI strong with CPI soft = blocked pass-through (margin compression) or lag not yet arrived; PPI soft with CPI strong = retail markup — the divergence points at margins, not inflation itself |
| Energy component | Headline monthly swings are mostly energy — decompose before reading the headline |
The advanced frame: PPI-to-CPI pass-through is conditional — with competitive pressure firms absorb costs (weak pass-through, margin squeeze); with supply tightness they pass them fast. So "PPI falling but CPI sticky" is not contradictory: upstream relief is being captured as retail markup. For trading, PPI matters more for inflation-week positioning than for any single-day move.
Limitations & common mistakes
- Using PPI as a CPI predictor: different baskets (PPI includes exports/government/capital equipment; CPI is a consumption basket) — pass-through lags and margins absorb; "PPI hot = CPI hot" does not follow.
- Reading only the headline: energy dominates monthly swings — undecomposed headline m/m is mostly noise.
- Ignoring services: the frame includes services now, and services map most directly to PCE — goods-only reading misses half the signal.
- Mixing up release order: both land in the same week (CPI first) — attributing PPI-day moves to CPI or vice versa is a classic timeline error.
- Over-celebrating upstream relief: PPI falling while retail markups persist (margin expansion) leaves CPI sticky — pass-through needs two conditions: costs falling AND competitive pressure.

FAQ
Q How does PPI differ from CPI?
Position: PPI measures producer selling prices (upstream, goods plus trade/transport services); CPI measures consumer retail prices (downstream). Baskets differ too — PPI includes exports and government purchases but not import prices (which sit in CPI). Released in the same week, PPI serves as an upstream lead for CPI — with lags and margin absorption.
Q When is PPI released?
Mid-month at 08:30 ET (21:30/22:30 Beijing depending on DST), usually one to two days after CPI — together they form "inflation week". Holiday weeks shift.
Q Core or headline PPI first?
Core (ex food & energy) first for the trend, then the energy component to explain the headline swing — reversing the order lets one month's energy pulse mislead you.
Q Why is CPI still sticky when PPI falls?
Pass-through is not automatic: falling upstream costs must survive the retail-markup stage — with weak competition, margin expansion captures the relief. The PPI-CPI divergence reads pass-through and margins, not "which one is wrong".
Q How much does PPI matter for trading?
Three layers: inflation-week positioning input (reshapes CPI-day expectations), a PCE forecasting reference (services mapping), and trend evidence (core PPI 3–6-month annualized). Its single-day elasticity is usually below CPI's.
