2.1.1 - The current account and external balance

Current-account flows and balances

The current account records flows between an economy's residents and the rest of the world during a stated period.

The balance of payments records an economy's international economic transactions. Its current account includes trade in goods and services, primary income such as investment income, and secondary income such as current transfers. It is not just the trade-in-goods balance, a household bank account or the stock of foreign reserves. Purchasing a foreign asset or receiving an overseas loan belongs in other balance-of-payments accounts; income earned on an investment is a current-account flow.

Exports are goods or services sold to customers abroad and bring receipts to domestic producers. Imports are goods or services purchased from abroad and involve payments to foreign producers. Trade in physical goods is traditionally called visibles: for example, exported machinery or imported fruit. Trade in services is called invisibles: for example, a foreign visitor buying domestic hotel services is a service export, while a resident paying a foreign software provider is a service import. “Invisible” does not mean unrecorded.

The current-account balance is receipts minus payments across its components. A positive balance is a surplus, zero is balance, and a negative balance is a deficit. The objective is often expressed as balance or surplus, but a surplus is not automatically proof of better living standards.

The goods deficit is £20 billion, but the current-account deficit is £5 billion: $-20+15+2-2=-5$. The figures are flows over one year. They do not show the stock of money or assets the country holds. If a simplified task supplies only exports and imports and states that other current-account components net to zero, the trade balance also gives the current-account balance. Do not assume that without evidence.

Quality and relative prices

Customers compare domestic and foreign products using both their prices and the benefits they offer.

Higher quality of domestic goods, such as reliable machinery with useful features and after-sales support, can increase export demand and encourage residents to buy domestically rather than import. Receipts may rise relative to payments, improving the trade contribution to the current account. Poor domestic quality can do the reverse. Higher quality of foreign goods can attract domestic import purchases and compete with domestic exports in overseas markets. These effects depend on customers valuing the quality differences, not just a producer calling its product “premium”.

The price of domestic goods matters relative to foreign alternatives. If domestic costs and prices rise while foreign prices and the exchange rate stay unchanged, exports may become less competitive and imports relatively attractive. Higher foreign prices can encourage buyers to switch toward domestic products, potentially strengthening exports and reducing import quantities. But expensive essential imports may increase the import bill if customers cannot easily reduce quantities. A price rise and the value of total payments are therefore different questions.

For an illustrative machine exporter, better reliability can protect orders despite a higher price. For a producer selling a standard product with many substitutes, a small price disadvantage may cause substantial lost sales. The current-account outcome depends on quantities and values of purchases across the economy, alongside income flows and transfers. Quality, price and exchange rates can operate together, so one factor alone need not explain an entire national surplus or deficit.
