Every month, two inflation reports land within 24 hours of each other — CPI on Tuesday, PPI on Wednesday. Markets move on both. The dollar reacts to both. And yet most retail traders only pay attention to one, or treat them as the same thing with different names.
They are not the same thing. They measure inflation at two completely different points in the supply chain, and when you read them together, you get a picture of where prices are coming from and where they are likely to go — which is far more useful than either number alone.
Here is what each one is, how they differ, and exactly how to use them together when you are trading dollar pairs like GBPUSD, EURUSD, or XAUUSD.
What CPI actually measures
CPI stands for Consumer Price Index. It tracks what ordinary people pay for a basket of everyday goods and services — food, housing, transport, healthcare, clothing, and more. The U.S. Bureau of Labor Statistics surveys thousands of prices across the country every month and compiles them into a single index.
When people say "inflation is at 4%," they are almost always referring to CPI — specifically the year-on-year change in that index. It is the most widely watched inflation measure in the world, and it is what the Fed references most often when talking about its 2% inflation target.
There are two versions you will see quoted:
- Headline CPI — includes everything, including food and energy prices
- Core CPI — strips out food and energy, since those tend to be volatile month to month. The Fed tends to focus more on core because it reflects more persistent, structural inflation rather than a one-month spike in petrol prices
What PPI actually measures
PPI stands for Producer Price Index. Instead of tracking what consumers pay, it tracks what businesses receive for the goods and services they produce — in other words, prices earlier in the supply chain, before those goods reach shops and households.
Think of it this way: if a factory that makes cooking oil sees its input costs rise — raw materials, energy, transport — that is what PPI captures. CPI captures what you eventually pay at the supermarket for that bottle of oil, after those costs have passed through the whole chain.
Like CPI, PPI also has a headline and a core version. And also like CPI, it is released monthly by the BLS, one day after CPI.
The key difference — and why it matters for traders
What households actually pay. This is the inflation the Fed is mandated to control. Moves markets immediately on release.
What businesses pay to produce goods. A leading indicator — rising PPI often shows up in CPI 1–3 months later.
The reason both matter to a forex trader is that they tell you different things about the inflation story and where it is heading.
CPI tells you where inflation is right now. It is what the Fed is reacting to today. A hot CPI print means the Fed has less reason to cut rates and more reason to hold or hike — which is generally dollar positive. A soft CPI print means inflation is cooling, which opens the door to eventual easing — generally dollar negative.
PPI tells you where inflation is going next. Because producer prices eventually pass through to consumer prices, a rising PPI is often a warning that CPI will follow higher in the coming months — even if this month's CPI was calm. This is why experienced macro traders do not ignore PPI just because it moves markets less dramatically on the day it lands.
How to read them together — the four scenarios
When CPI and PPI land in the same week, the most useful thing you can do is read them as a pair rather than as two separate events. There are four combinations, and each one tells a different story for the dollar:
CPI beats + PPI beats. The strongest dollar signal. Inflation is elevated at the consumer level right now, and the pipeline is full — more is likely coming. The Fed has maximum reason to stay hawkish. This is the combination that most aggressively prices out rate cuts and prices in holds or hikes. Dollar strengthens, GBPUSD and EURUSD tend to fall, Gold tends to come under pressure.
CPI misses + PPI misses. The clearest dovish signal. Inflation is cooling at the consumer level, and the pipeline is easing — there is no new pressure building. This is the combination that most aggressively prices in rate cuts. Dollar weakens, GBPUSD and EURUSD tend to rise, Gold often rallies.
Current inflation elevated, pipeline cooling. The market will react to the hot CPI initially — dollar positive. But a soft PPI underneath suggests the pressure may ease in coming months. This is a "hold hawkish for now, but watch the next few prints" scenario. The initial dollar strength may not hold for as long as a clean double-hot reading.
Current inflation cooling, pipeline still pressured. The trickiest combination. CPI softening is initially dollar negative — but a hot PPI is a warning that the relief may be temporary. Traders who only watch CPI may sell the dollar, while macro-aware traders are more cautious knowing the next CPI print could reverse the trend.
Why the first reaction is not always the right one
One of the most consistent patterns around CPI releases is that the market's initial move often gets fully or partially reversed within the same session. This happens because the market reacts to the headline number first, then starts digesting the details — core vs headline, month-on-month vs year-on-year, what PPI said the day before.
A trader who only watches the headline CPI number and reacts immediately is working with half the picture. A trader who also has the PPI read in context, knows the current Fed stance, and has a macro bias built before the release — that trader is in a position to distinguish between a real trend shift and a one-day reaction.
This is exactly the approach the SOG Capital Macro Tracker is built around. Rather than reacting to each release in isolation, it holds the full picture — CPI, PPI, NFP, FOMC stance, COT positioning, and CME rate odds — updated together as each data point lands, so you can see how the new number fits into the existing macro story rather than just whether it beat or missed.
A note on this week specifically
June CPI drops Tuesday July 14 and PPI follows Wednesday July 15. These two releases are the final major inflation inputs before the July 28–29 FOMC meeting, where the Fed will decide whether to hold, hike, or signal a change in direction.
The current setup coming into this week: the June NFP badly missed expectations (57K vs 115K forecast), which softened hike odds from 32% down to around 22%. But the FOMC minutes released last week confirmed the committee dropped its easing-bias language and that a few members wanted to hike at the June meeting — inflation remains their primary concern.
That means this week's CPI and PPI are carrying more weight than usual. If both come in hot, the NFP miss gets discounted and hike odds recover. If both come in soft, a genuinely two-sided picture opens up for the first time this cycle. The four scenarios above are exactly the framework to have in mind when the numbers land.
