The short answer
The US Consumer Price Index, CPI, is published monthly by the Bureau of Labor Statistics at 08:30 New York time, which is 13:30 in London, usually in the second week of the month. It reports the change in prices paid by urban consumers across a fixed basket of goods and services for the previous month, and it is the most market-moving inflation print on the calendar because it lands before the Fed’s preferred PCE gauge and immediately reshapes the rate path priced into the dollar. The cleanest read is not the headline year-over-year number alone but the combination of headline, core, which excludes volatile food and energy, supercore, services excluding shelter and energy that the Fed watches closely for wage-driven inflation, and month-over-month change. A hot CPI, prints above consensus on core and supercore, pushes Fed cuts further out, lifts the dollar and US yields, and pressures gold. A soft CPI does the mirror. The first ten minutes after 13:30 UK are violent and dominated by algorithms; the cleaner setups appear from minute two onward, with second-instrument confirmation between the dollar index, gold and US 10-year yields.
What CPI is and when it lands
The US Consumer Price Index is produced monthly by the Bureau of Labor Statistics and tracks the average change in prices paid by urban consumers for a fixed basket of goods and services. The release lands at 08:30 New York time, which is 13:30 in London, almost always on a Tuesday or Wednesday in the second week of the calendar month, for the prior month’s data. The published report gives you the headline year-over-year change, the headline month-over-month change, the core measures that strip out volatile food and energy, and detailed breakdowns by category. The fixed-basket design is its main limitation, because shoppers change what they buy when prices move, which is why the Fed actually targets the broader PCE gauge instead. But CPI lands first, the data is not revised, and the entire market trades it on release, which is why it dominates inflation day.
Why it moves the dollar and gold so hard
Three reasons. First, CPI is the first hard read on inflation for the month and the surprise versus consensus immediately reprices the Federal Reserve’s expected rate path, which is the single biggest driver of the dollar and Treasury yields. Second, because the Fed actually targets PCE, traders use the CPI components, especially shelter, services and supercore, to forecast the PCE that lands two weeks later, which doubles the importance of the breakdown. Third, the surprise is genuine: consensus forecasts often miss the actual core monthly print by a tenth or two, and the algorithms react in milliseconds to that gap. The combination routinely produces 60-to-100 pip moves in the dollar pairs in the first minutes, with gold and US 10-year yields swinging hard alongside. The 2026 backdrop, with core PCE running near the mid-4 percent range and the Fed pinned, has made every CPI a higher-stakes event than usual, because each print could be the one that tilts the committee toward a cut or a hold.

What to actually read on release, beyond the headline
Reading only the headline year-over-year number is how new traders get whipsawed. The desk reads four things together. First, headline and core versus consensus, because that is the immediate surprise the market trades. Second, the month-over-month change, especially on core, because year-over-year prints are heavily influenced by base effects from a year earlier and the monthly run rate is what tells you whether inflation is accelerating or decelerating right now. Third, the supercore measure, services excluding shelter and energy, because it captures the sticky wage-driven inflation that the Fed cares about most for its rate decisions. Fourth, the shelter component, the largest single contributor to CPI, which has its own lagged dynamics and can move the headline on its own. A clean hawkish print is core above consensus, supercore hot, monthly run rate accelerating, shelter not cooling. A clean dovish print is the mirror. Anything else is a mixed message, and mixed messages are where the desk waits for the dust to settle.

How the desk trades inflation day, before and after
Before the release, the desk does two things. It marks the consensus for headline and core CPI on screen so the surprise versus that bar is instantly readable, and it shrinks position size on existing dollar, gold and US index trades, because CPI day blows out normal stop distances. On release, the desk does not trade the first thirty seconds, because that move is algorithmic, spreads widen, and the headline can be misread before core and supercore register. From minute two to roughly minute ten the market typically retraces or extends as humans absorb the full report, and that is where the cleaner setups appear. The mistake to avoid is fading the initial spike on instinct; the right move is to read the full picture, confirm the dollar’s direction with a second instrument like gold or US 10-year yields, then trade the established reaction sized for the wider range. CPI is not where the desk swings for fences, it is where the desk takes one well-defined trade and is done. The PCE-vs-CPI piece linked below explains why core PCE matters even more for the medium-term rate path.
The desk’s checklist
- Mark the consensus before the release. Note the consensus for headline CPI, core CPI and month-over-month change on screen at 13:25 UK. The market trades the surprise versus that bar, not the absolute number.
- Shrink size on related trades. CPI day blows out normal stop distances on dollar pairs, gold and US indices. Cut size or step out ahead of 13:30 UK so a routine print does not flush you on noise.
- Skip the first thirty seconds. The first half-minute is algorithmic and spreads widen. Let the market price headline, core and the monthly change before you commit, because the components often soften or amplify the headline.
- Read core, month-over-month, supercore, shelter. A clean hawkish print needs core above consensus, monthly run rate accelerating, supercore hot, shelter not cooling. Mixed prints deserve patience, not size.
- Trade the established move with second-instrument confirm. From minute two to ten, take the trade only if a second instrument like gold or US 10-year yields agrees with the dollar’s direction. Size for the wider range and respect the stop.
Frequently asked
When is the US CPI released?
The Consumer Price Index is published by the Bureau of Labor Statistics at 08:30 New York time, which is 13:30 in London, almost always on a Tuesday or Wednesday in the second week of the calendar month, for the prior month’s data.
Why does CPI move forex so much?
Because it is the first hard inflation read of the month and immediately reprices the Federal Reserve’s expected rate path, which is the biggest driver of the dollar and US yields. A hot CPI pushes Fed cuts further out and lifts the dollar; a soft one brings cuts forward and weakens it.
What is core CPI and why does it matter?
Core CPI strips out the volatile food and energy components from the headline. It matters more for trading the Fed because the central bank is trying to read the persistent underlying trend it can influence with policy, not a one-off spike from an oil move. A hot core print is more hawkish than the same hot headline driven by energy.
What is supercore CPI?
Supercore is services CPI excluding shelter and energy. It is the cleanest gauge of the sticky, wage-driven services inflation that the Federal Reserve cares about most for its rate decisions, because it strips out the lagged shelter component and the noisy energy services. A hot supercore reading is a strong hawkish signal even when the headline cools.
How do you trade CPI step by step?
Mark the consensus before 13:30 UK, shrink size on related trades, skip the first thirty seconds while algos and wide spreads dominate, then read headline together with core, month-over-month, supercore and shelter. From minute two to ten, take one well-defined trade in the direction the full report supports, confirmed by a second instrument like gold or US 10-year yields, sized for the wider range.
CPI produces some of the sharpest, fastest moves on the calendar. To trade those releases you need fast, reliable execution and tight pricing on the dollar pairs, gold and US indices. The desk’s broker stack:
