A current account deficit means a country is spending more abroad than it earns from abroad. It covers more than just trade in goods: it includes services, income from overseas investments and money transferred between countries. The UK has run a current account deficit for most of the past few decades, and that fact shapes how investors think about sterling, especially in times of stress.
What goes into the current account
The current account is part of a country’s balance of payments, the record of all its financial dealings with the rest of the world. It has several components.
- Trade in goods, the difference between exports and imports of physical products such as cars, machinery and food.
- Trade in services, which covers things like financial services, insurance, tourism and consulting.
- Primary income, mainly the returns earned on overseas investments, such as dividends and interest, minus what foreign investors earn on their investments in the UK.
- Secondary income, which includes transfers like foreign aid and payments to international organisations.
If the total is negative, the country has a current account deficit. Our guide to the trade balance covers the first part of that picture in more detail.
The UK’s position
The UK typically imports more goods than it exports, giving it a large goods deficit. It partly makes up for this with a strong surplus in services, thanks to the City of London, professional services and other exports. Even so, the overall current account has usually been in deficit.
That shortfall has to be financed. If a country spends more abroad than it earns, the difference must be covered by money flowing in from overseas investors, who buy UK assets such as gilts, shares, property and companies. In other words, a current account deficit is balanced by a surplus in what is called the financial account.
The kindness of strangers
In 2016, the then Bank of England Governor Mark Carney described the UK as relying on “the kindness of strangers” to finance its current account deficit. The phrase stuck because it captured the vulnerability neatly. As long as foreign investors are happy to put money into UK assets, the deficit is easily funded. If their confidence falters, they may demand a lower pound or higher interest rates before they are willing to keep investing.
This is one reason sterling can be sensitive to political and fiscal shocks. When investors worry about UK policy, the need for continuous foreign funding can amplify moves in the currency and in gilts. The market turmoil after the September 2022 mini-budget showed how quickly confidence can shift.
Is a deficit always bad?
Not necessarily. A deficit can reflect strong domestic demand, healthy investment or a country that is attractive to foreign capital. The United States has run large deficits for decades while the dollar has remained the world’s leading reserve currency. Many fast-growing economies run deficits as they import machinery and technology to build their industries.
The questions that matter are how large the deficit is relative to the size of the economy, how it is financed and how stable that financing is. Long-term foreign direct investment, such as building factories, is generally considered more stable than short-term flows into bonds, which can leave quickly.
Why traders watch it
Current account data is published quarterly in the UK and rarely moves markets on the day, because it is released with a lag. Its importance is more structural. A large or widening deficit can leave a currency more exposed to shifts in global risk appetite. In risk-off periods, currencies of deficit countries often weaken, while those of surplus countries such as Switzerland and Japan have tended to strengthen.
It also links to interest rates. A country that relies on foreign capital may need to offer attractive returns to keep that capital flowing, which is one reason interest rate expectations matter so much for sterling.
Bringing it together
A current account deficit means a country spends more abroad than it earns, and must attract foreign money to fill the gap. The UK has lived with one for decades, relying on overseas investors to buy its assets. That does not doom the pound, but it does help explain why sterling can react sharply when confidence wobbles, and why the second-order question is always who is funding the gap and how willing they remain.
