GBP/USD "Cable" — profile of the fastest major pair

A first position on GBP/USD ends the same way for a great many people. The trader carries over habits from EUR/USD, sets a stop loss sixty points below the entry, and a quarter of an hour later watches it get hit — even though the direction eventually turned out to be right. The pound against the dollar simply moves wider and faster, and the market does not ask what the reader is used to. Below I explain where the name "Cable" came from, what a pip is really worth on this pair, what moves it, and why it is called the fastest of the majors.

Where does the name "Cable" come from?

The name is older than the currency market in its present shape. The first transatlantic telegraph cable was laid in 1858, though it worked for only a few weeks; a permanent link between Britain and North America went into service in 1866. Before that, the pound-dollar rate crossed the ocean aboard a mail steamer, with a delay measured in days. Once the quote began to travel by telegraph, London dealers simply spoke of "the cable". The market forgot the telegraph; the name stayed.

What is a pip worth on Cable?

A pip on GBP/USD is the fourth decimal place, that is 0.0001 dollar on every pound. A standard lot covers 100,000 pounds, so one pip of movement changes the result of such a position by 10 USD. A mini lot gives a dollar per pip, a micro lot ten cents. Because the dollar is the quote currency, the result arises in dollars, and on an account denominated in zloty it is converted at the prevailing USD/PLN rate. The same number of pips can therefore come out as a slightly different amount in zloty in two different months.

In the Bank for International Settlements survey of 2022, GBP/USD accounted for roughly 9.5 percent of daily global turnover. That is the third-largest share — behind EUR/USD and USD/JPY — and a solid place among the major pairs, but the proportion is worth remembering: EUR/USD handles more than twice as much turnover. That difference in market depth is the first reason Cable behaves differently.

Why does Cable move faster than EUR/USD?

A shallower market means fewer resting orders at every price level. The same impulse — a large institutional order, a surprising inflation print — pushes the quote further before the other side of the trade appears. In quiet hours the difference can go unnoticed, but at the moment data is released, or after London closes, it becomes obvious.

The second reason is the scale of the economy. Britain is many times smaller than the United States and than the euro area, and its trade and financial balance depends more heavily on the mood of foreign capital. A single Bank of England decision weighs more in the pricing of the pound than a single ECB decision does in the pricing of the euro, because on the other side there is no bloc of twenty-odd countries.

The third reason is political, and I will come back to it separately. Together they produce a pair with a distinctly wider daily range than EUR/USD — and with a larger share of moves that end back where they started. For a trader that means two things at once: more opportunities and more false signals.

What actually moves the pound?

The strongest point in the calendar is the Bank of England. The Monetary Policy Committee meets eight times a year and announces its Bank Rate decision at noon London time, which is 13:00 CET, usually on a Thursday. The British central bank also has a feature the Fed and the ECB lack: it publishes the committee's vote split immediately. The rate itself may land exactly where the market expected, and the market still reacts, because the vote split says which way the next decision is leaning.

The second point is inflation. The UK statistics office releases the consumer price index in the morning, around 8:00 CET, roughly in the middle of the month. Labour market data and the quarterly reading of gross domestic product come on top of that. The third factor is the dollar leg — Federal Reserve decisions and US data move Cable exactly as they move any other dollar pair, except that in a shallower market the reaction tends to be sharper.

The political legacy of 2016

The referendum on Britain's exit from the European Union changed the pound's status. Since June 2016 the market has treated sterling as a politically sensitive currency: a general election, a change of prime minister, an argument over the shape of trade agreements or the recurring question of Scottish independence can move the rate harder than many a macro release. The sharpest illustration came in the autumn of 2022 — after the budget presented by Liz Truss's government, the pound slid against the dollar to the lowest level in the history of the quote, and the Bank of England had to intervene in the bond market.

The practical conclusion is not "don't trade the pound". It is: before you open a position, check the British political calendar as carefully as the macroeconomic one. There are weeks in which technical analysis on Cable is simply beside the point, because the rate is being decided by a vote in the House of Commons.

How is this pair traded?

Cable is a London session pair. The deepest liquidity and the tightest spread fall roughly between 9:00 and 17:30 CET, and the liveliest trading tends to come in the first hours after the London open and after 14:00, when New York joins in — if that mechanism interests you, I describe it at greater length in the profile of the London session. Outside that window, especially in Asian hours, the spread widens and the moves turn random.

The character of the pair also dictates the choice of interval. Cable works well in position trading on the four-hour and daily charts, where wide moves work in your favour rather than against you. On five- and fifteen-minute intervals the same phenomenon turns into noise: breakouts that go nowhere, and stops hit on the way to the right target. Scalping this pair means paying the spread in a market that can give back several dozen pips on its own anyway.

Hence the most common beginner's mistake: carrying position size and stop width straight over from EUR/USD. Since the typical daily range here is larger, the stop has to be correspondingly wider — and for the risk in money terms to stay the same, the position has to be smaller. That one calculation separates deliberate trading on Cable from the frustration described at the start.

What to do before you open your first Cable position

1. Measure the daily range of both pairs. Put an average true range indicator on the daily charts of GBP/USD and EUR/USD, write down both values and divide one by the other. The ratio you get is the multiplier by which you have to widen your stop loss and by which you have to shrink your position size if you want to risk the same amount of money on Cable as on EUR/USD.
2. Convert the risk into money, not pips. Take the position size you intend to open, multiply it by the pip value (10 USD on a standard lot, a dollar on a mini, ten cents on a micro) and by the width of the stop, then convert the result at the current USD/PLN rate if your account is in zloty. Only that amount tells you whether the position fits your plan.
3. Put the eight Bank of England dates in your calendar. Meeting dates are published a year in advance; move them into your own calendar with a reminder for 13:00 CET and note beside them the date of the next UK inflation release. That alone is usually enough to keep you from entering a position a quarter of an hour before an announcement.
4. Test one approach on the four-hour chart. For a month, trade Cable only during London session hours and only on the four-hour interval, recording the reason for every entry in your journal. Then compare the outcome with the trades you took earlier on lower intervals — the difference usually settles the argument about noise on its own.
