GBP/JPY: how much does it move, when, and what moves it?
Close to close it moves 55 pips against USD/JPY's 53. The beast reputation is intraday range, not displacement. A derived series, and we say so.
GBP/JPY gets called the beast, and it has a case: 93% of its days clear 100 pips. But the reputation comes from its intraday range, and once you measure what it actually travels from one close to the next, a different pair appears — one that looks far more like the yen than like the pound.
This is the only entry in the series we do not measure directly, and that is worth knowing before reading a single figure.
How the numbers were built, and their limit. GBP/JPY is not in our price history, so it is derived from its two legs: GBP/JPY = GBP/USD × USD/JPY. The derived close is exact. The hourly range is not: it is built from the highs and lows of both legs, which do not occur in the same second, so it is an upper bound. Everything below says so where it matters. Hourly bars, last two years, 521 Monday-to-Friday days, Sundays excluded. Hours in UTC.
How much does GBP/JPY move in a day?
Start with the exact number, which is the close-to-close one:
| Pair | Daily close-to-close move | Upper bound on range |
|---|---|---|
| USD/CHF | 24 pips | 53 pips |
| EUR/USD | 28 pips | 64 pips |
| GBP/USD | 36 pips | 80 pips |
| USD/JPY | 53 pips | 112 pips |
| GBP/JPY | 55 pips | ~179 pips |
There is the finding: close to close, GBP/JPY moves 55 pips and USD/JPY moves 53. Two pips apart. The whole distance between 179 and 112 is intraday range — out and back within the session — plus whatever the derived method inflates.
Put another way: GBP/JPY does not travel twice as far, it takes twice as many turns getting there. For an intraday trader that is real and it is more risk. For someone holding across days, far less than the reputation suggests.
On the range percentiles, which are upper bounds: a quiet day runs about 105 pips and a busy one 315. And not one of the 521 days came in under 40. Remember a yen pip is the second decimal — what a pip is and how to calculate its value — and to turn it into currency there is the position size calculator.
What hours is it genuinely alive?
| Window (UTC) | Median hourly range (upper bound) |
|---|---|
| 22:00–05:00 · Asia | 31 to 55 pips |
| 06:00–08:00 · London opens | 54 to 64 pips |
| 09:00–11:00 · European morning | 47 to 53 pips |
| 12:00–16:00 · London–New York overlap | 55 to 76 pips |
| 17:00–21:00 · New York afternoon | 31 to 45 pips |
The peak sits at 14:00 UTC and the trough at 22:00, a gap of 2.4 times. And here is its second quirk: 69% of its range falls in the London–New York overlap, ahead of even USD/CAD — though the figure comes from a derived series, so read it as an order of magnitude.
That is the opposite of USD/JPY, which splits its day across two peaks and concentrates only 53% in the overlap. GBP/JPY inherits the Tokyo open from its yen leg — which is why 00:00 UTC still delivers 55 pips — but the sterling leg adds the London morning, and the result is a pair that concentrates more, not less. The map is in forex trading sessions and in session overlaps; live, on the session clock.
What moves GBP/JPY?
The short answer is the yen, far more than the pound. And it measures.
| What it moves with | Correlation of daily returns |
|---|---|
| USD/JPY | +0.70 |
| GBP/USD | +0.25 |
The "sterling pair" is really a yen pair in a sterling coat. When the Bank of Japan (BoJ) moves, or when the threat of currency intervention appears, this pair feels it more than it feels the Bank of England (BoE) speaking.
And underneath it all the dollar is still there, even though it is not in the name: both legs carry it, which is why US data moves this pair even though it is a cross. A concrete stretch of its history is in GBP/JPY's rally; to size a position with a release coming, the news risk calculator.
What does not move it, despite appearances?
The pound, mostly. At +0.25 against GBP/USD, taking a GBP/JPY position to express a view on sterling gets you halfway at best: three quarters of the movement comes from somewhere else. If your thesis is about the pound, the pair that expresses it is GBP/USD or EUR/GBP, not this one.
And its reputation. "The most volatile pair" is true by intraday range and misleading by displacement. Those 55 close-to-close pips leave it two pips from USD/JPY, which nobody calls a beast.
Is it a good pair to start on?
No. Not because of the volatility as such, but because the volatility it has is the kind that punishes sizing errors: a lot of out-and-back travel inside the day, where a normal stop gets taken out by noise and a wide one carries a large loss when it is wrong.
If you trade it anyway, size with ATR (Average True Range) rather than the median, and watch the spread: on a cross with no dollar in it, the spread is usually wider than on the majors, and that eats a share of the range the figures above do not deduct.
What these numbers do not tell you
- It is a derived series. The close is exact; the hourly range is an upper bound, because the two legs' highs do not coincide to the second.
- 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, and on this pair that weighs more than on the majors.
- The granularity is one hour, so a five-minute spike is invisible.
- This is not a forecast. It describes how the pair has behaved; the past shapes the expectation, never the outcome.
