GBP/USD: how much does it move, when, and what moves it?
An 80-pip median day and only 5% of sessions under 40. The same clock as EUR/USD, turned up. Measured on 521 days of our own price history.
GBP/USD gets called the nervous pair, almost always without a number attached. Here is the number: it covers 80 pips on a normal day, 25% more than EUR/USD, and clears 100 pips on three sessions out of ten.
What follows is its three constants — how much, when and why — measured against our own price history.
How the numbers were built. Hourly bars from January 2021 to September 2026. The headline figures use the last two years, 521 Monday-to-Friday days, with Sundays excluded because they are half a session. Every hour below is UTC.
How much does GBP/USD move in a day?
The median daily range is 80 pips. If that unit means nothing to you yet, start with what a pip is and how to calculate its value.
| Kind of day | Range |
|---|---|
| Very quiet (10th percentile) | 47 pips |
| Quiet (25th percentile) | 62 pips |
| Typical (median) | 80 pips |
| Busy (75th percentile) | 107 pips |
| Very busy (90th percentile) | 141 pips |
The figure that captures it best is not the median, it is the floor: only 5% of days fail to reach 40 pips. For EUR/USD that share is 15%, and for USD/CHF 24%. GBP/USD almost never sits still.
| Pair | Median daily range | Days under 40 pips |
|---|---|---|
| USD/CHF | 53 pips | 24% |
| USD/CAD | 59 pips | 17% |
| EUR/USD | 64 pips | 15% |
| GBP/USD | 80 pips | 5% |
| USD/JPY | 112 pips | 4% |
⚠️ That table compares pips, not money: a USD/JPY pip is not worth what a GBP/USD pip is worth. To turn range into currency, use the position size calculator.
What hours is it genuinely alive?
| Window (UTC) | Median range per hour |
|---|---|
| 22:00–05:00 · Asia | 8 to 12 pips |
| 06:00–08:00 · London opens | 15 to 20 pips |
| 09:00–11:00 · European morning | 16 to 17 pips |
| 12:00–16:00 · London–New York overlap | 17 to 24 pips |
| 17:00–21:00 · New York afternoon | 10 to 15 pips |
The peak sits at 14:00 UTC with 23.9 pips and the trough at 23:00 with 7.6 — a threefold spread inside one day. And 61% of the daily range happens in the London–New York overlap, the same proportion as EUR/USD.
Which is the part that surprises people comparing the two: the clock is identical. Same 14:00 peak, same 61% in the overlap, and a best-hour-to-worst-hour gap of 3.1 times against EUR/USD's 3.0. What differs between the two pairs is not the hour they move in, but how much: GBP/USD is EUR/USD turned up. The full map is in forex trading sessions and in session overlaps, and you can follow it live on the session clock.
What moves GBP/USD?
The dollar first, sterling second — and that ranking is measurable.
- US data. In the hour non-farm payrolls are released, GBP/USD's range is 2.10 times its range for that same hour on an ordinary day. The control that validates the measurement is EUR/GBP, which carries no dollar and only reaches 1.30.
- The distance between central banks: not what the Federal Reserve (the Fed) does, nor what the Bank of England (BoE) does, but the gap between them.
- Inflation in both countries, since it is what those two decisions hang on. The mechanism is in what inflation is.
Note that its multiplier on a US release, 2.10, is the lowest of the five dollar pairs we measured. Not because the data matters less: because its normal noise level is already high, so the release stands out less against the background. When one is coming, the news risk calculator turns that into position size.
What does not move it, despite appearances?
Trading it alongside EUR/USD is not diversification. We measured the correlation of both pairs' daily returns over the same window: +0.80. Buying both is one bet against the dollar at double the size — the reasoning is in currency correlation, and the other half of this series is EUR/USD.
And its nickname explains nothing about its character. It is called cable after the submarine telegraph line that joined London and New York in 1866, not after any property of the pair: the story is in why GBP/USD is called cable. What does survive from that is the geography — it is still the pair of those two cities, and that is where it moves.
If what you want is sterling without the dollar in front of it, the pair that isolates that story is EUR/GBP, whose correlation with GBP/USD is −0.28: effectively a different market.
And be careful with the other sterling cross: GBP/JPY correlates just +0.25 with GBP/USD, so it does not express a view on sterling either — three quarters of its movement comes from the yen.
Is it a good pair to start on?
It depends what you compare it against. Its advantage is that there is almost always range: only one day in twenty stays under 40 pips, so strategies that need distance rarely run dry.
Its cost is the same figure read backwards: 30% of days clear 100 pips, and a stop sized for EUR/USD comes up short here. The tool for that is not the median but ATR (Average True Range), which adapts to the volatility of these weeks. And always measure the spread against the range you expect, never in the abstract.
What these numbers do not tell you
- The median is not your day. It describes the centre of a distribution, not what happens tomorrow.
- No spread and no slippage are inside it. Our history stores prices, not costs, so everything above is gross range.
- The granularity is one hour, so a five-minute spike is invisible and these figures understate the first move on a release.
- It is a single feed — our broker's, normalised to UTC. Another would give similar numbers, not identical ones.
- This is not a forecast. It describes how the pair has behaved; past behaviour shapes the expectation, never the outcome.
