What it means
Think of a country as a large household. It owns things abroad, such as foreign shares, bonds, factories and bank deposits, and foreigners own things inside it.
Net foreign assets is what is left after subtracting what foreigners own at home from what residents own overseas. The measure comes from a country's international investment position, a statement of its overseas assets and liabilities at a point in time.
Countries with a long history of trade surpluses, such as large exporters, often build up positive balances. Countries that have run deficits for many years, financing them by borrowing from abroad, tend to have negative balances.
The figure matters because it tells you how exposed a country is to the rest of the world. A large positive position acts as a cushion in a crisis, since the country can draw on its overseas holdings.
A large negative one means the country must keep attracting foreign funding and pay income abroad on its debts, which can strain the currency if investors lose confidence. The same label is used in banking statistics.
A central bank's net foreign assets are its foreign currency reserves minus its foreign liabilities, and the banking system's net foreign assets are used to understand money supply and credit growth. Analysts at the International Monetary Fund and in central banks track these numbers closely.
The nuance is valuation. Overseas assets are priced in foreign currencies and market values, so the figure changes when exchange rates and asset prices move, even without any new investment.
A country can therefore see its net foreign assets fall in a bad year for markets without having borrowed a cent more. Because different sources define the banking version slightly differently, it is wise to read the footnotes before comparing two countries.
Differences in what counts as a foreign liability can move the headline figure by a meaningful amount.
In practice
Real-world examples.
Example
A sovereign wealth fund invests oil revenue in foreign shares and bonds over many years. By the end of a decade the country's overseas holdings far exceed foreign claims at home. Its net foreign assets are strongly positive and help the currency in bad times.
Example
A fast-growing country finances a large trade deficit by selling bonds and property to foreign investors. Its net foreign assets turn negative by $300 billion. Analysts watch whether the economy can generate enough export earnings to pay the interest.
Example
A central bank reports foreign currency reserves of $120 billion and foreign liabilities of $20 billion. Its net foreign assets are $100 billion. The governor uses the figure when explaining how much support the bank could give the currency.
Formula
Calculation
Net foreign assets = foreign assets owned by residents - domestic assets and liabilities owed to foreigners
A country's residents and government hold foreign assets worth $900 billion, while foreigners hold assets in the country and claims on it worth $650 billion. Net foreign assets = 900 - 650 = +$250 billion. The country is a net creditor, and if the same figures were reversed the result would be -$250 billion, a net debtor position.Case study
Seen in the real world.
Zephyria is a fictional island economy that sells fish and tourism services. In this illustrative story, it ran trade deficits for ten years and borrowed from overseas banks to cover them. Its net foreign assets slid from zero to minus $12 billion, roughly 60% of its yearly output.
When global lenders became nervous, the currency fell by 25% and the cost of servicing the debt jumped. The government then adopted a plan to cut imports, encourage exports and build a reserve fund. A decade later, the net foreign position had improved to minus $4 billion, showing how a weak position makes a country vulnerable and how steady policy can repair it. Officials noted that the recovery took patience, since every improvement had to come from real exports and savings and not from accounting changes.
Watch out
Common mistakes.
- Treating negative net foreign assets as a sign of failure. Many successful economies are net debtors because they attract investment that earns high returns.
- Confusing it with the trade balance. Trade is a flow over a period, while net foreign assets is a stock at a point in time.
- Ignoring valuation changes. Exchange rate and market moves can change the figure without any new borrowing or lending.
Questions
People also ask.
How does net foreign assets differ from foreign reserves?
Reserves are assets held by the central bank, while net foreign assets include the holdings of everyone in the country and subtract what is owed to foreigners.
Why does it matter to the currency?
A strong positive position gives confidence, and a weak one can make investors fear a funding squeeze.
Where is the data published?
The International Monetary Fund and national statistics offices publish international investment position data, usually quarterly or yearly.
