PPI is the producer price index, an early read on inflation. Here's why prices at the factory gate lead CPI and how the release moves a currency.

What is PPI? - Karnek

PPI stands for the producer price index. It tracks what producers charge at the factory gate — the wholesale prices of goods before they reach the shop shelf. It matters to traders because it tends to move before CPI does. When it costs more to make things, that cost usually reaches the consumer a month or two later. PPI is inflation caught earlier in the pipeline.

What it is

PPI measures inflation from the seller's side rather than the shopper's. Statisticians survey the prices producers receive for their output — raw materials, components, finished goods leaving the factory. Like CPI, it is quoted a few ways:

Headline PPI — the full basket, including food and energy.
Core PPI — the same basket with volatile food and energy stripped out.
Year-on-year and month-on-month — the annual figure for the trend, the monthly for momentum.

Because producer costs feed into shop prices, a rising PPI is often the first sign that consumer inflation is coming.

Why it leads

Think of the supply chain as a pipeline. A manufacturer's costs rise first; those costs pass to wholesalers, then to retailers, and finally to the shopper who sees a higher price at the till. CPI captures the last step; PPI captures an earlier one. So when PPI climbs while CPI is still calm, traders read it as a warning that CPI will follow — and that the central bank may have to keep rates higher to cool it. That expectation, not the PPI number itself, is what moves the currency.

PPI does not always feed through cleanly. Producers sometimes absorb higher costs to protect market share, so a hot PPI need not become a hot CPI. Treat it as an early signal, not a promise.

An example

Suppose US PPI is forecast at 0.2% for the month and prints at 0.6%. The market reads it as inflation building upstream and reprices the Fed a touch tighter. EUR/USD might slip 30 to 40 pips as the dollar firms. A trader long one standard lot of EUR/USD — roughly £8 a pip — could see £240 to £320 come off the position. The reaction is usually smaller than a CPI surprise, because PPI is a lead indicator rather than the confirmed consumer number.

Why it matters

PPI is a scheduled release, often landing the day before or after CPI, and traders use it to set expectations for the bigger print.

Leading — it can flag a change before CPI confirms it.
Scheduled — a known date and time you can plan around.
Secondary — it moves price less than CPI, but it colours how CPI is read.

For an automated strategy the point is timing. PPI rarely causes the violent spike CPI can, but it is still a high-impact number, and an EA trading blind into it takes on slippage the calendar could have flagged.

The Karnek note

Karnek watches your live account, not the data wire, so it will not trade a PPI release or step aside before one. What it does is record how your EAs behaved through the event — the positions they held, the slippage they took, the drawdown that followed — straight from the terminal. Karnek can never open or close a trade on the account.
