Trade Deficit vs Trade Surplus

Trade Deficit and Trade Surplus are two International Trade & Finance concepts in AP Economics that students often mix up. In short: trade deficit is a trade deficit occurs when a country's imports exceed its exports, making net exports negative. Meanwhile, trade surplus is a trade surplus occurs when a country's exports exceed its imports, making net exports positive. Here is how they compare side by side.

Trade Deficit

A trade deficit occurs when a country's imports exceed its exports, making net exports negative.

It is financed by borrowing from or selling assets to foreigners, recorded as a surplus in the financial account. A deficit is not inherently bad; it can reflect strong domestic demand or investment inflows. It is the opposite of a trade surplus.

Trade deficit = Imports − Exports (when positive).
Trade Surplus

A trade surplus occurs when a country's exports exceed its imports, making net exports positive.

It adds to aggregate demand and means the country is a net lender to the rest of the world. It corresponds to a deficit in the financial account. It is the opposite of a trade deficit.

Trade surplus = Exports − Imports (when positive).
