GBP/USD in one paragraph
GBP/USD is the exchange rate of one British Pound in US dollars and the third most traded pair in global forex. A quote of 1.2800 means one pound costs 1.28 US dollars. Traders call it Cable because the rate was first transmitted between London and New York over the 1866 transatlantic telegraph cable. Daily ranges of 80 to 120 pips are routine, roughly 30 to 50 percent higher than EUR/USD, because the UK is one open economy reacting to a single central bank rather than a 20-country bloc. The pair trades 24 hours from Sunday 5:00 PM ET to Friday 5:00 PM ET.
Why GBP/USD is called Cable
The Cable nickname is literal. In 1866 the SS Great Eastern finished laying the first reliable transatlantic telegraph cable between Valentia Island in Ireland and Heart's Content in Newfoundland. Before that, the GBP/USD exchange rate moved between London and New York at the speed of a steamship, roughly 10 days each way, and the two cities frequently quoted different prices.
Once the cable opened, the rate could be transmitted in minutes. Bullion dealers and bank clerks on both sides of the Atlantic began calling the quote the cable rate, and within a generation Cable was the standard floor-trader shorthand for pound-dollar. Sterling has lost its 19th-century role as the global reserve currency, but the nickname survived every regime change that followed: gold standard, Bretton Woods, the 1971 float, and the modern era of fiat majors.
Cable is the third most traded forex pair after EUR/USD and USD/JPY, capturing roughly 11 percent of global daily volume in the most recent BIS triennial survey. It is the primary FX channel for UK-US capital flows, the largest bilateral investment relationship in the world after EU-US, and the main hedging vehicle for sterling-denominated assets held outside the United Kingdom.
Quick fact. The 1866 cable was 4,200 km long, 25 mm thick, and could transmit roughly eight words per minute. By comparison, GBP/USD quotes on MT5 today update many times per second from aggregated bank and non-bank liquidity, and round-trip from London to New York in well under 100 milliseconds.
How GBP/USD is quoted and what a pip is worth
The GBP/USD quote tells you how many US dollars one British pound costs. If GBP/USD prints 1.2800, one pound is 1.28 dollars; if it prints 1.2900, the pound has strengthened by one cent. GBP is the base currency and USD is the quote currency. A quote of 1.2850 means the bid (the price you can sell at) and ask (the price you can buy at) sit around that level, separated by the spread.
A pip on Cable is the fourth decimal place: 0.0001. A move from 1.2800 to 1.2810 is a 10-pip move. JPY pairs use the second decimal (0.01) as the pip, but for all the other majors including GBP/USD, the standard pip is the fourth decimal. The fifth decimal (the so-called pipette) is half a pip; MT5 displays five decimals on Cable to show that finer increment.
Lot sizing on MT5 is standardised. One standard lot of GBP/USD is 100,000 units of the base currency, which is 100,000 pounds. A mini lot is 0.1 lots (10,000 pounds), a micro lot is 0.01 lots (1,000 pounds), and 0.01 is the minimum tradable size at LHFX. At a GBP/USD price of 1.2800, the notional value of one standard lot is roughly 128,000 US dollars.
Pip value on GBP/USD is fixed in the quote currency: every pip on one standard lot is worth 10 US dollars, regardless of where the pair is trading. On a mini lot it is 1 dollar per pip, and on a micro lot it is 10 cents per pip. That makes Cable position sizing straightforward: pick the pip value you can stomach on a stop, then size the lots backwards.
Worked example
You buy 0.10 lots of GBP/USD at 1.2800. That is 10,000 pounds of exposure, roughly 12,800 dollars of notional. At 1:500 leverage the margin required is about 26 dollars. Price moves to 1.2900, a 100-pip move in your favour, and pip value at 0.10 lots is 1 dollar per pip, so the trade returns 100 dollars. The same 100-pip move against you costs 100 dollars. On a 1,000 dollar account that is 10 percent risk on a single trade, so the prudent size for a 2 percent risk budget on a 100-pip stop is 0.02 lots, not 0.10.
What moves GBP/USD
Cable is a two-leg trade: every move reflects the pound side, the dollar side, or both. The catalysts cluster into central bank decisions, the underlying yield spread, UK political events, and global risk sentiment.
Bank of England policy
The BoE Monetary Policy Committee meets eight times a year, on a fixed schedule published in advance. The decision lands at 12:00 noon London (7:00 AM ET) and the Monetary Policy Report follows on the same day for four of those meetings. The 9-member voting split is published in the same release and frequently moves Cable more than the headline rate itself. A hawkish vote split with no hike still tightens BoE expectations and lifts GBP/USD; a dovish split with no cut does the opposite.
Federal Reserve policy
FOMC meets eight times a year. The statement lands at 2:00 PM ET and Chair press conferences follow 30 minutes later. Hawkish Fed surprises strengthen the dollar and push GBP/USD down; dovish surprises weaken the dollar and push Cable up. On Fed days the dollar leg dominates and Cable typically tracks the broader DXY move in mirror image.
UK-US 2-year yield spread
The single cleanest medium-term GBP/USD driver is the spread between 2-year UK Gilt yields and 2-year US Treasury yields. When UK yields rise faster than US yields (the spread widens in sterling's favour), Cable trends higher over multi-week windows. When the spread compresses or inverts, Cable trends lower. The 2-year tenor is preferred because it captures the market's pricing of the next 8 BoE and FOMC meetings, which is the horizon that actually moves spot.
UK CPI and labour data
UK CPI is released on the third Wednesday of each month at 7:00 AM London (2:00 AM ET). Headline, core, and services inflation each get parsed separately because the BoE has repeatedly flagged services CPI and wage growth as the stickier components. Average weekly earnings land the Tuesday before CPI; the two together drive most of the BoE rate-path repricing each month and can move GBP/USD 40 to 80 pips in the first 30 minutes after release.
UK politics and the Budget
The Autumn Budget (typically late October or November) and the Spring Statement (March) are the two scheduled fiscal events. Both move Cable on tax, gilt-issuance, and borrowing announcements. The September 2022 mini-budget produced a same-week 7 percent drop in GBP/USD and forced a Bank of England gilt-market intervention; that episode is the modern reference point for how fast Cable can move on a UK fiscal surprise. Election cycles, leadership challenges, and cabinet reshuffles add ad-hoc gap risk.
Global risk sentiment
GBP/USD has a moderate risk-on tilt: in broad risk-on tape, capital rotates out of the dollar and into higher-beta majors including sterling, pushing Cable up. In sharp risk-off episodes the dollar rallies as global capital flows into Treasuries, and Cable falls faster than EUR/USD because of the UK's smaller, more open economy. S&P 500 weekly direction is a useful crosscheck on GBP/USD swing trades.
When does GBP/USD trade?
Cable trades 24 hours a day, five days a week, from Sunday 5:00 PM ET through Friday 5:00 PM ET. Liquidity follows the sun: Asia is thin, London is the volume centre, and the London-New York overlap is where the deepest book and the highest volatility sit. Cable is a London pair first, and the heaviest order flow lands during UK business hours.
Roughly 40 percent of all daily Cable volume passes through the London session, with another 25 to 30 percent during the four-hour London-NY overlap. Asian hours typically print the tightest ranges; New York afternoon thins out as London desks close and US traders square risk into the close. UK data is released at 7:00 AM London (2:00 AM ET); US data lands at 8:30 AM ET, deep in the overlap.
Roughly 6:00 PM to 3:00 AM ET. Quieter, narrower ranges of 20 to 40 pips. Cable mostly tracks USD/JPY direction during this window.
Roughly 3:00 AM to 8:00 AM ET. Spreads tighten sharply, ranges expand. UK CPI, wages, GDP, and retail sales all print at 7:00 AM London (2:00 AM ET) on their respective days.
Roughly 8:00 AM to 12:00 PM ET (1:00 PM to 5:00 PM London). The most liquid and most volatile window. US CPI, NFP, and PCE land at 8:30 AM ET; FOMC at 2:00 PM ET on meeting days.
Roughly 12:00 PM to 5:00 PM ET. Liquidity thins as London closes. Ranges narrow unless FOMC, a Fed speaker, or a US political headline hits the tape.
How the BoE and Fed combine to set the trend
Every GBP/USD move reflects expectations for both central banks. The clean way to think about Cable is the relative policy path: it is not whether the BoE hikes, but whether the BoE hikes more or less than the Fed over the next 12 months that the market is pricing.
BoE hike or hawkish surprise
Pound strengthens. UK yields rise relative to US yields, the 2-year UK-US spread widens in sterling's favour, and GBP/USD lifts. A 25 basis point surprise hike with a hawkish vote split typically delivers a 60 to 120 pip move in the first session and a multi-week trend if the spread keeps widening.
BoE cut or dovish surprise
Pound weakens. UK yields fall relative to US yields, the spread compresses, and GBP/USD drops. A 25 basis point surprise cut typically delivers a similar 60 to 120 pip move in the opposite direction. Forward guidance shifts in the Monetary Policy Report can produce the same effect without any change in the headline rate.
Fed hike or hawkish surprise
Dollar strengthens. US yields rise relative to UK yields, the spread compresses against sterling, and GBP/USD falls. Because the dollar moves against every pair simultaneously, Cable typically tracks the broader DXY move on FOMC days, with the magnitude scaled by Cable's higher beta.
Fed cut or dovish surprise
Dollar weakens. US yields fall relative to UK yields, the spread widens in sterling's favour, and GBP/USD rallies. The 2024 to 2026 dollar weakening cycle has been the cleanest recent example: every dovish FOMC surprise produced a multi-day Cable rally as the UK-US spread reopened.
Policy divergence trades
The cleanest Cable trends happen when the BoE and Fed move in opposite directions over a quarter or longer. BoE on hold while Fed cuts is sterling-positive; BoE cuts while Fed holds is sterling-negative. Watch the BoE and Fed dot-plot or implied-rate paths from short-sterling and Fed funds futures; the spread between the two is the cleanest input for a swing-trade thesis.
How GBP/USD compares to other liquid majors
Cable sits between EUR/USD (slower, lower beta) and GBP/JPY (faster, higher beta). Picking the right pair for your account size and stop tolerance matters more than picking the right direction.
| Pair | Typical daily range | Beta vs EUR/USD | Primary drivers | Typical raw spread |
|---|---|---|---|---|
| GBP/USD | 80 to 120 pips | 1.3 to 1.5x | BoE, Fed, UK-US 2y spread | From 0.0 pips |
| EUR/USD | 50 to 80 pips | 1.0x (baseline) | ECB, Fed, EU-US 2y spread | From 0.0 pips |
| GBP/JPY | 120 to 200 pips | 1.8 to 2.5x | BoE, BoJ, risk sentiment | From 0.5 pips |
GBP/USD has roughly 30 to 50 percent more daily range than EUR/USD because the UK is one open economy reacting to a single central bank rather than a 20-country bloc. The same Bank of England decision moves all of sterling at once; an ECB decision is filtered through 20 different national economies and dampens the FX impact.
If your stop is tighter than 50 pips you may want EUR/USD; if you have stop tolerance above 100 pips and a multi-day thesis, Cable usually pays better. GBP/JPY amplifies both the BoE leg and risk sentiment but is too volatile for most beginner position sizes.

Risks of trading GBP/USD
Cable is liquid and well-understood, but it carries more event-driven risk than EUR/USD. The combination of higher daily volatility, scheduled UK fiscal events, and high available leverage means losses compound faster than on lower-beta pairs.
Event-driven volatility
BoE decisions, MPC vote splits, UK CPI, and UK wages data routinely move Cable 60 to 120 pips inside 30 minutes. FOMC days add the same on the dollar leg. A 100-pip move on 1:500 leverage is a 50 percent return or a 50 percent loss on margin, depending on direction.
Weekend and political gaps
Cable closes Friday 5:00 PM ET and reopens Sunday 5:00 PM ET. UK political headlines (no-confidence votes, leadership changes, snap-election calls, Budget leaks) regularly produce gap opens of 50 to 200 pips. The September 2022 mini-budget saw GBP/USD gap roughly 7 percent in a single trading session. Stop losses cannot protect across a closed market.
Leverage amplifies both sides
1:500 leverage on GBP/USD means a 0.2 percent adverse move wipes out the margin on a fully-leveraged position. Cable moves 0.5 to 1 percent on most days and 2 to 5 percent on major event days. Size positions to your account, not to the leverage cap.
UK political headline risk
The UK has had five prime ministers in the last decade and frequent cabinet reshuffles. Headlines can hit the tape outside scheduled data windows, producing 50 to 100 pip moves on no prior notice. Brexit-era headlines were the extreme example; the underlying mechanism (sterling repricing on a single UK news item) has not gone away.
