A trade deficit occurs when the value of an economy’s imports exceeds the value of its exports over a specified period. It is a negative trade balance, calculated as exports minus imports.
The coverage matters. A goods deficit covers merchandise, while a goods-and-services deficit includes services such as travel and transport. A country can have a goods deficit and a services surplus at the same time.
How is a trade deficit calculated?
Suppose an economy exports $100 billion of goods and services and imports $120 billion during a year. Exports minus imports equals negative $20 billion, usually described as a $20 billion deficit.
The BEA defines the trade balance as the difference between exports and imports. Both figures must use the same period, currency and coverage. When exports exceed imports, the result is a trade surplus.
Why does a deficit occur?
A deficit can reflect strong domestic spending, imports of machinery for investment, the prices of traded goods or comparatively weak foreign demand. It does not necessarily mean that domestic businesses cannot produce enough goods.
A bilateral deficit concerns trade with one partner. It differs from an economy’s total balance with the rest of the world.
Is it the same as a current account deficit?
No. The current account includes trade plus primary and secondary income balances. These include investment income and current transfers such as remittances. Their amounts can change the sign or size of the broader balance.
The saving and investment relationship applies to the current account: a shortfall in national saving relative to investment corresponds to a current account deficit, allowing for statistical discrepancies. National saving includes private and government saving. It is not the government budget balance alone.
How is it financed?
The broader balance-of-payments accounts record the financial counterparts to trade and income transactions. These can involve borrowing, foreign purchases of equity or changes in holdings of overseas assets. They are not limited to loans from foreign governments.
The IMF explains that the sustainability of an external deficit depends on its causes and financing. Financing productive investment has different implications from financing spending that creates little future income. Dependence on funding that can reverse quickly can create risks.
Does it weaken the currency or economy?
A deficit does not guarantee a currency fall, job losses or a recession. Exchange rates also respond to interest rates, capital flows and expectations. The trade balance alone does not show which currency was used for individual payments.
Imports are subtracted in GDP expenditure accounting to remove foreign production already included in spending. That accounting treatment does not mean every imported item mechanically reduces domestic output.
A narrowing deficit also needs explanation. Starting with exports of $100 billion and imports of $120 billion, either a $10 billion export increase or a $10 billion import decrease would reduce the deficit to $10 billion.
The import decline might reflect weaker domestic demand. The export increase might reflect stronger overseas sales. The balance alone cannot distinguish those conditions.
Do tariffs necessarily reduce it?
Tariffs are taxes on imports. They can reduce some imports, but their effect on the overall balance also depends on exchange rates, retaliation, input costs, saving and investment. Dallas Fed analysis finds that the aggregate outcome is uncertain, rather than a guaranteed correction.
