Whether you're a UK traveler heading to the States, a US business paying a British supplier, or just curious why the pound is worth what it is, this guide explains what moves the pound to dollar rate and how to get a fair deal when you convert.

Why is it called "cable"?

The nickname dates back to the 1800s, when GBP/USD quotes were sent between London and New York over a transatlantic telegraph cable. The name stuck, and traders still use it today.

What moves the GBP/USD rate

The pound-dollar rate is driven by the relative strength of two economies and, crucially, the gap between their central banks' interest rates.

1. Interest rate differentials (BoE vs Fed)

This is the single biggest driver. When the Bank of England holds rates higher than the US Federal Reserve, holding pounds pays more interest, which tends to support GBP. When the Fed is more aggressive, the dollar strengthens.

Watch both central banks' meetings and the language in their statements — markets often move more on the expected path of rates than on the decision itself.

2. Inflation and growth data

UK and US inflation (CPI), jobs numbers, and GDP releases shift expectations for future rate moves. A hot UK inflation print that makes more BoE hikes likely can lift the pound within minutes.

3. Risk sentiment and the dollar's safe-haven status

The US dollar is the world's reserve currency and a safe haven. In times of global stress, money flows into dollars, which usually pushes GBP/USD down regardless of UK fundamentals.

4. UK-specific politics

Budgets, elections, and major policy shifts can move the pound sharply. The currency is sensitive to anything that changes the outlook for UK growth or government borrowing.

The typical GBP/USD range

Historically the pound has traded across a wide band against the dollar — from above 2.00 in 2007 to near parity territory under stress. In recent years it has more often ranged in the 1.20–1.40 zone. Rather than memorize a number, compare today's quote with the recent range on the history chart, which now shows up to five years of data.

How to convert pounds to dollars at a fair rate

The rate you see in the news is the mid-market rate — the midpoint between buy and sell prices in the wholesale market. It's the fairest benchmark, but it's not always what providers give you. Here's how to get close to it:

Start from the mid-market rate. Open the live GBP/USD converter and treat that number as your benchmark. Any provider quoting a worse rate is charging a hidden spread.
Look at total cost, not "zero fees." A "no-fee" deal with a poor exchange rate often costs more than a small flat fee on a fair rate. See our guide on converting money without fees.
Avoid airport and hotel kiosks. Their spreads are among the worst you'll find.
For larger transfers, mind the timing. You can't predict the market, but avoiding obviously volatile days helps — see the best time to convert currency.

Is now a good time to convert pounds to dollars?

There's no universal answer — it depends on the recent range and your needs. Compare today's quote with the recent history on the live converter. If you're getting close to the mid-market rate with low fees, that's a good deal.

Why is GBP usually worth more than USD?

A higher number doesn't mean a "stronger" or "better" currency — it just reflects the historical exchange ratio between the two. What matters is how the rate changes over time, not the absolute figure.
