Economic Data That Moves Markets: CPI, Jobs, GDP and PMIs

Module 6C: Fundamentals for Technical Traders · Lesson 1 of 4 · Back to course

Even if you only ever trade from a chart, economic data still affects you. A few scheduled releases each month can move a currency pair or an index more in one minute than it moved all morning. You don’t need to become an economist. You do need to know what the big releases are, when they come out in UK time, and why markets react to them the way they do.

Why a chart trader should care

Technical analysis studies what price has done. Fundamental analysis looks at what might make it move: the economy, interest rates and money flows. Most beginners don’t need to trade the news, but they do need to avoid being ambushed by it. A perfectly good setup can be wiped out because the UK inflation figure came out two minutes after you entered.

The practical goal of this lesson is simple: know which releases matter, check the economic calendar every day before you trade, and have a written rule for what you do around them.

The big four

1. Inflation (CPI)

The Consumer Prices Index (CPI) measures how fast the prices of everyday goods and services are rising. It matters because central banks set interest rates largely to control inflation. The Bank of England’s target is 2% CPI inflation. If inflation is running hot, markets start to expect higher interest rates (or fewer cuts), and that usually supports the currency. We cover the link properly in Lesson 6C.2.

  • UK CPI is published by the Office for National Statistics (ONS) at 07:00 UK time, usually on a Wednesday around the middle of the month, for the previous month.
  • US CPI is published by the Bureau of Labor Statistics (BLS) at 8:30am Eastern time, which is normally 13:30 UK time.
  • Watch the “core” figure too. It strips out volatile items like food and energy, and markets often react to it as much as to the headline.

2. Jobs data

A strong jobs market can push wages and inflation up, so it feeds into interest-rate expectations too.

  • UK labour market figures (unemployment, employment and wage growth) come from the ONS at 07:00 UK time, usually on a Tuesday. Wage growth is often what UK markets focus on.
  • US Non-Farm Payrolls (NFP) – the US “Employment Situation” report – is published by the BLS at 8:30am Eastern (normally 13:30 UK), usually on the first Friday of the month. It’s one of the most-watched releases in the world and can move GBP/USD, gold and US indices sharply.

3. GDP

Gross domestic product (GDP) measures the total output of the economy – whether it’s growing or shrinking. The ONS publishes a monthly UK GDP estimate as well as quarterly figures, at 07:00 UK time. GDP looks backwards (it describes a month or quarter that has already ended), so markets often react less to it than to CPI or jobs – unless it’s a big surprise.

4. PMIs (business surveys)

A Purchasing Managers’ Index (PMI) is a monthly survey of businesses asking whether things like output, new orders and hiring are better or worse than last month. A reading above 50 means more businesses reported improvement than deterioration; below 50 means the opposite.

  • PMIs are fast: the “flash” (early) estimates come out before the end of the month they describe.
  • For the UK, S&P Global publishes its UK PMIs at 09:30 UK time. Manufacturing usually comes on the first working day of the month and services on the third, with flash readings later in the month.

Key release times in UK time

Release Who publishes it Usual time (UK) Usual day
UK CPI inflation ONS 07:00 Wednesday, mid-month
UK labour market ONS 07:00 Tuesday, mid-month
UK GDP (monthly) ONS 07:00 Mid-month
UK PMIs S&P Global 09:30 Flash late in month; final early in month
US CPI BLS 13:30 (see note) Mid-month
US Non-Farm Payrolls BLS 13:30 (see note) Usually first Friday

The clock-change trap. US releases at 8:30am Eastern are at 13:30 UK time for most of the year. But the US and UK change their clocks on different dates. For a week or so in late October/early November, and for two to three weeks in March, the gap shrinks to four hours and the same releases come out at 12:30 UK time. In 2026, UK clocks go back on 25 October and US clocks on 1 November, so US data between those dates lands an hour earlier for UK traders than usual. Always check the time on your calendar, not from memory.

Times and patterns checked on the official ONS, BLS and S&P Global release calendars on 17 October 2026. For example, the ONS lists UK CPI for September 2026 at 07:00 on Wednesday 21 October 2026, and the BLS lists the October 2026 jobs report for 8:30am Eastern on Friday 6 November 2026 (13:30 UK). Dates can change, so always use the official calendars or your platform’s economic calendar.

Why the surprise matters more than the number

Before each release, economists publish forecasts, and a typical “consensus” figure appears on every economic calendar. Markets are forward-looking, so by release time the consensus is largely already in the price. What moves the market is the surprise: the difference between the actual number and what was expected.

  • Actual close to the forecast: often a small, short-lived reaction.
  • Actual well above or below the forecast: often a sharp move, wider spreads and slippage.
  • Revisions matter too. If last month’s figure is revised a lot, that can outweigh this month’s number.

Even then, the first move is not reliable. Price often spikes one way, then reverses as traders digest the detail. That’s why many experienced traders simply stay out for a few minutes either side of major releases.

Common mistakes

  • Not checking the calendar. Entering a trade at 06:58 on UK CPI day without realising is one of the most common beginner accidents.
  • Trying to guess the number. Even professional forecasters miss regularly. Guessing the direction of the surprise is a coin flip with very wide spreads.
  • Assuming a “good” number means the currency goes up. Markets react to the surprise and to what it means for interest rates, not to whether the news sounds good.
  • Trusting your stop to protect you. In a fast release, a normal stop-loss can be filled well past its level. A guaranteed stop avoids that but costs extra.
  • Forgetting the clock-change weeks. See the table note above.

Example (illustrative numbers)

All figures are made up for teaching purposes. They aren’t real data, real prices or a trade idea.

Suppose the consensus forecast for UK annual CPI inflation is 3.0%, and it comes out at 3.4%. That’s a surprise on the high side. A typical reaction might be:

  • Traders think the Bank of England is less likely to cut rates soon.
  • The pound strengthens: GBP/USD jumps from 1.2600 to 1.2660 (60 pips) in the first few minutes.
  • Spreads, normally 1 pip, briefly widen to several pips.

Now imagine you had a short GBP/USD trade open with a stop 20 pips above your entry, at 1.2620. In a jump like that, your stop might be filled at 1.2640 instead – a loss twice the size you planned. If your position size assumed a 20-pip loss, you’ve just lost twice your planned risk. And if the figure had come out at exactly 3.0%, the move might have been 10 pips and gone nowhere. Neither outcome was predictable in advance.

The prop firm angle

Prop firm rules and economic news are a risky mix:

  • Some firms restrict trading around high-impact news on some account types – for example, not opening or closing trades a few minutes either side. Others allow it. Read the rules for your exact account; breaking a news rule can void a challenge or a payout (see Module 15).
  • Slippage counts towards your daily loss limit. One badly filled stop at 13:30 on payrolls day can push you through a daily loss limit you thought you had room for.
  • A simple, defensible rule for a challenge: no new trades from 15 minutes before to 15 minutes after any high-impact release for the currencies or index you trade, and consider reducing or closing positions beforehand. Write it into your plan.

Key takeaways

  • The big scheduled releases are inflation (CPI), jobs, GDP and PMIs, plus central bank decisions (next lesson).
  • UK ONS data usually comes out at 07:00 UK time; key US data at 8:30am Eastern, normally 13:30 UK, but 12:30 in the clock-change gaps.
  • Markets react to the surprise versus the forecast, and the first move often reverses.
  • For most beginners, the aim is to avoid being caught out, not to trade the release.

Quick quiz

  1. At what time (UK) does the ONS usually publish UK CPI? (07:00.)
  2. Why might GBP/USD rise after a higher-than-expected UK CPI figure? (Markets may expect higher interest rates, or fewer cuts, which tends to support the currency.)
  3. What moves markets more: the actual figure or the difference from the forecast? (The difference from the forecast – the surprise.)
  4. US Non-Farm Payrolls is released at 8:30am Eastern. What time is that in the UK for most of the year? (13:30. It’s 12:30 during the short gaps when US and UK clocks have changed on different dates.)
  5. A PMI reading of 48 suggests what? (More businesses reported things getting worse than better – a contraction signal.)

Try this

Open a free economic calendar (most platforms and charting sites have one) and set it to UK time. For the next week, write down every high-impact release for GBP and USD, with the UK time. On a demo or free chart of GBP/USD, mark each release time with a vertical line. Afterwards, look at the five minutes before and after each one: how far did price move, and did the first move last? You’re not looking for a trading signal – you’re learning what “news risk” looks like so it doesn’t surprise you.

FAQ

Do I need to understand economics to trade? No, but you need to know when the big releases are and have a rule for them. That alone avoids a lot of avoidable losses.

Is news trading a good strategy for beginners? It’s one of the hardest: spreads widen, slippage is common and the first move often reverses. Most beginners are better off standing aside.

Where do I find release times? The official sources are the ONS release calendar (UK data), the BLS release schedule (US jobs and CPI) and the S&P Global PMI calendar. Your platform’s economic calendar pulls these together; make sure it’s set to UK time.
