How Exchange Rates Work — A Plain-English Guide

Exchange rates are the prices at which one country's currency can be traded for another. They are determined primarily by the foreign exchange (forex) market — the largest, most liquid financial market in the world, with over $7 trillion traded every day. Unlike stock markets, forex operates 24 hours a day, five days a week, across financial centers in Sydney, Tokyo, London, and New York.

What Drives Currency Values?

No single factor determines exchange rates, but the most influential drivers are:

• Interest rates: When a central bank raises interest rates, its currency typically strengthens. Higher rates attract foreign capital seeking better returns, increasing demand for that currency. The US Federal Reserve and Bank of England's rate decisions are closely watched by currency traders worldwide.
• Inflation: Countries with lower inflation tend to see their currencies appreciate. Higher inflation erodes purchasing power — a pound or dollar buys less over time, making it less attractive to hold. Central banks use interest rate policy partly to control inflation.
• GDP growth: Strong economic growth signals a healthy economy, attracting foreign investment and strengthening the currency. Weak growth or recession tends to weaken a currency as investors flee to safer assets.
• Trade balance: A country that exports more than it imports (trade surplus) creates stronger demand for its currency from foreign buyers. The UK has historically run trade deficits, which creates downward pressure on GBP over time.
• Political stability: Uncertainty drives investors away. Events like Brexit (2016–2020) caused significant GBP volatility, with the pound dropping sharply on the referendum result and again during deal negotiations.

A Brief History of the USD/GBP Rate

The US Dollar and British Pound have one of the longest and most storied exchange rate histories in modern finance. For much of the 19th and early 20th centuries, the British Pound was the world's reserve currency — the dollar was worth less than a quarter of a pound. After World War II, the Bretton Woods system fixed the pound at $2.80. When the fixed system broke down in 1971, the pound floated freely. It hit a historic low of $1.054 in February 1985 during the strong-dollar era. The peak in modern history was around $2.10 in 2007, just before the global financial crisis.

The 2016 Brexit referendum was the most dramatic recent event for GBP/USD, causing the pound to crash from around $1.48 to $1.33 overnight — one of the largest single-day moves in currency history. By 2022, the pound briefly fell below $1.04 following the disastrous Truss government mini-budget, before recovering. As of early 2025, the rate hovers around $1.26 (1 GBP = ~$1.26 USD, or 1 USD = ~£0.79).

Tips for Getting Better Exchange Rates When Traveling

Understanding the gap between the "mid-market rate" (what you see on Google) and what you actually pay is key to saving money abroad. Banks and airport kiosks typically charge 3–8% above the mid-market rate. Here is how to minimize that gap:

• Use a travel-focused debit or credit card (Wise, Revolut, Charles Schwab) that charges little or no markup over the mid-market rate.
• Withdraw cash from local ATMs at your destination rather than exchanging at home. The local bank network typically offers better rates than tourist-area kiosks.
• Always decline "dynamic currency conversion" (DCC) — if a merchant or ATM asks whether you want to pay in your home currency instead of the local currency, always choose the local currency. DCC rates are notoriously poor.
• Avoid hotels, airports, and train station exchange counters. Competition is low and rates are poor in these captive environments.
