Inflation, employment, and growth data
How inflation, jobs, and growth data shape central-bank expectations — and why the surprise matters more than the number.
Lesson 2 of 2 · 7 min read
Central banks don't set rates at random. They react to data — above all inflation, the labour market, and economic growth. Each important release nudges the market's expectations for future interest rates, and those expectations move currencies. Once you understand that chain, economic data stops looking like a random list of numbers and starts reading like a story you can follow.
What you'll learn
- The chain from economic data to rate expectations to exchange rates
- The key inflation measures: CPI, core CPI, and PCE
- The key labour-market data: payrolls, unemployment, and wages
- Growth indicators: GDP, PMIs, and retail sales
- Why the surprise versus consensus matters more than the number itself
1. The chain that moves currencies
Economic data → central-bank expectations → interest-rate expectations → currency
(Illustrative.) US inflation comes in higher than expected.
- The market concludes the Fed may need to keep rates higher for longer.
- Expected US interest rates rise; short-term Treasury yields move up.
- Holding dollars becomes relatively more attractive.
- USD tends to strengthen — EUR/USD falls, USD/JPY rises.
Every data point in this lesson matters because of step 1: what it changes about the central bank's likely next move.
2. Inflation
Inflation is the rate at which prices rise. Most major central banks target around 2%. When inflation runs well above target, pressure builds for higher rates; well below, for lower rates.
| Measure | What it is | Why traders watch it |
|---|---|---|
| CPI (Consumer Price Index) | Change in prices of a basket of consumer goods and services | The headline inflation number in most countries — often the biggest monthly market mover |
| Core CPI | CPI excluding volatile food and energy prices | Shows the underlying trend; central banks and markets often focus on it |
| PCE price index (US) | Personal consumption expenditures prices | The Federal Reserve's preferred inflation measure |
| PPI (Producer Price Index) | Prices received by producers | Can hint at future consumer-price pressure |
Each is usually reported month-over-month (m/m) and year-over-year (y/y). A single hot month matters more when it confirms a trend than when it looks like a one-off.
3. The labour market
Central banks watch jobs closely: a tight labour market can push up wages and, eventually, inflation. For the Fed, maximum employment is half of its mandate.
The US employment report (non-farm payrolls, or NFP) is released by the Bureau of Labor Statistics, usually on the first Friday of the month at 8:30 a.m. New York time. It contains three numbers traders watch:
| Figure | What it tells you |
|---|---|
| Non-farm payrolls | How many jobs were added or lost last month |
| Unemployment rate | The share of the labour force without a job |
| Average hourly earnings | Wage growth — a direct link to inflation pressure |
Other countries publish their own labour data — for example the UK's monthly labour market report, Canada's Labour Force Survey, and Australia's employment report.
4. Growth
| Indicator | What it measures | Notes |
|---|---|---|
| GDP | Total economic output | Quarterly; important, but backward-looking and often well anticipated |
| PMIs (Purchasing Managers' Indices) | Surveys of business activity in manufacturing and services | Monthly and timely; above 50 = expansion, below 50 = contraction |
| Retail sales | Consumer spending at retailers | Consumer spending drives much of many developed economies |
| Business and consumer confidence | Survey-based sentiment | Can signal turning points early |
Strong growth supports the case for higher (or at least not lower) rates; weakening growth builds the case for cuts.
5. The surprise is what moves price
For every scheduled release, economists publish a consensus forecast. That forecast is largely already reflected in the price before the number comes out.
What moves the market is the deviation from consensus.
Worked example
(Illustrative.) US CPI y/y — consensus 3.1%, previous 3.2%.
| Actual | vs consensus | Likely read | Typical USD reaction |
|---|---|---|---|
| 3.4% | +0.3 above | Inflation hotter than expected → rates higher for longer | USD stronger |
| 3.1% | In line | Nothing new | Small or brief move |
| 2.8% | −0.3 below | Inflation cooling faster → cuts more likely | USD weaker |
Note that the 3.1% outcome is lower than the previous month — yet the market barely reacts, because a fall to 3.1% was already expected.
Reading the whole release
Headline numbers rarely tell the full story. Professionals check:
- Core vs headline
- Revisions to previous months
- Components — for example, wages inside the jobs report, or services inflation inside CPI
- Consistency with other recent data
Mixed releases — strong headline, weak details — often produce a sharp first move that reverses within minutes.
6. Putting it together
A simple framework for any currency:
- What is the central bank focused on right now? (Inflation, jobs, or growth — the focus changes over time.)
- What does the market expect it to do next?
- Which upcoming data could change that expectation?
- What result would count as a surprise — in each direction?
If you can answer these four questions for the two currencies in a pair, you understand the macro backdrop better than most retail traders.
Common beginner mistakes
- Comparing the release to the previous month instead of to the consensus forecast.
- Reacting only to the headline and ignoring core, revisions, and components.
- Treating all data as equal. A central bank focused on inflation will care much more about CPI than a confidence survey.
- Forgetting the other currency in the pair. Strong US data can be overshadowed by stronger data from the other economy.
- Assuming the first move is the real move. Initial reactions often reverse once the details are digested.
Key terms
| Term | Meaning |
|---|---|
| CPI / core CPI | Consumer price inflation / excluding food and energy |
| PCE | Personal consumption expenditures price index — the Fed's preferred inflation gauge |
| NFP | US non-farm payrolls — monthly change in employment |
| Average hourly earnings | Wage growth measure inside the US jobs report |
| GDP | Gross domestic product — total economic output |
| PMI | Survey-based activity index; above 50 = expansion |
| Consensus | The median economist forecast for a release |
| Revision | A later change to previously published data |
Practice
- Find the latest US CPI release: headline and core, m/m and y/y, versus consensus. Was it a surprise? Which way did USD move in the following hour?
- Do the same for the latest NFP: headline, unemployment rate, average hourly earnings, and revisions.
- For the two currencies in your favourite pair, write down what each central bank is most focused on right now.
- List the three data releases next week most likely to change expectations for those central banks.
Quick recap
- Data moves currencies by changing expectations for central-bank policy.
- Inflation (CPI, core, PCE), jobs (payrolls, unemployment, wages), and growth (GDP, PMIs, retail sales) are the core releases.
- The market reacts to the surprise versus consensus, not the number in isolation.
- Read the whole release — core, revisions, and components — not just the headline.
- Always consider both economies in a pair.
