How Macro Data Moves Prices
The moment inflation, jobs or interest rate decisions are released, stocks, bonds and currencies often swing hard together. What matters isn't whether the data is good or bad, but how far it is from expectations.

Text version · Fundamental Analysis, lesson 6: “How Macro Data Moves Prices”
The moment inflation, jobs or interest rate decisions are released, stocks, bonds and currencies often swing hard together. What matters isn't whether the data is good or bad, but how far it is from expectations.
The market trades the surprise
Before the release, prices already reflect what the market expects. What moves them is the surprise: actual minus expected. “Good data” that falls short of even better expectations is still bad news.
It all comes back to interest rates
CPI and nonfarm payrolls matter because they change what the market expects from the policy rate, and that ripples through bond yields, stock valuations, exchange rates and gold.
First, ask what the market is afraid of
The same jobs beat is good news when the market fears a recession and bad news when it fears inflation. Work out what the biggest worry is right now before judging which way the data will push prices.
Key takeaways
- Markets trade the "surprise": the gap between the actual and expected number is what moves prices.
- Inflation above expectations → more rate hikes expected → bond yields rise, stocks come under pressure, and the home currency tends to strengthen.
- The same data can have opposite effects at different times, depending on whether the market is more worried about inflation or recession.
Try it yourself
You can do these exercises in this lesson's interactive simulation:
- In CPI, drag the actual to match the forecast (3.0%): the four assets barely move. Why?
- Drag CPI to 3.6%: how much do yields, the stock index, the local currency and gold each move?
- Switch to nonfarm payrolls and drag the actual to 50K jobs (far below the expected 180K): which way do yields move? Is it the opposite of the last step?
- Switch to the rate decision (default actual 5.50%, 0.25% more than expected): how many bp did yields jump? How far did the stock index fall?
Quiz and explanations
- 1. CPI comes in far above expectations. What's the most typical first reaction?
- Answer: Bond yields rise and stocks come under pressure.An inflation surprise means the central bank may hike faster.
- 2. The data is "great" but the stock falls. What's the most likely reason?
- Answer: The market expected even better.The price already reflected higher expectations, so falling short of them is still a negative surprise.
- 3. The market expects CPI of 3.2%, and the actual figure is 2.9%. What's the most likely typical reaction?
- Answer: Yields fall and gold strengthens.Inflation below expectations → more rate cuts expected → yields fall, and non-yielding gold becomes relatively more attractive.
Terms in this lesson
- CPI (Consumer Price Index): The consumer price index, the most widely used measure of inflation; a bigger-than-expected rise usually means pressure to hike rates.
- nonfarm payrolls (Nonfarm Payrolls): The monthly count of new US non-farm jobs, showing how hot or cold the economy and job market are.
- policy rate (Policy Rate): The benchmark rate set by a central bank, which drives borrowing costs across the economy.
- surprise (Surprise): The gap between the released figure and what the market expected; prices react to the surprise, not to whether the data is good or bad.
