Mini Lesson
International trade is the buying and selling of goods and services across national borders. It is now so common that almost everything in your bedroom — phone, clothes, books, electronics — has crossed at least one border on its way to you. Understanding the vocabulary of trade lets you read economic news and follow global events with much sharper eyes.
Exports and Imports
An export is a good or service that a country sells to another country. An import is a good or service that a country buys from another country. The same product can be both: a Japanese car is an export when it leaves Japan and an import when it arrives in Germany. Money flows in the opposite direction — out of the importing country, into the exporting country.
Trade Balance, Surplus, Deficit
- Trade balance = total value of exports minus total value of imports.
- Trade surplus — exports are larger than imports. Money flows IN. Germany and China often run trade surpluses.
- Trade deficit — imports are larger than exports. Money flows OUT. The United States and the United Kingdom often run trade deficits.
- A deficit is not automatically "bad". A growing economy may buy lots of foreign goods because its citizens are wealthy and businesses are investing.
Tariffs
A tariff is a tax that one country places on goods coming in from abroad. If a country puts a 25% tariff on imported steel, foreign steel costs 25% more, and domestic steel becomes more competitive. Governments use tariffs to protect home industries, raise revenue, or as a political tool. The downside: tariffs raise prices for consumers and can trigger retaliatory tariffs from other countries.
Trade Agreements
A trade agreement is a formal deal between countries that reduces tariffs and other barriers to trade. The North American free trade agreement (signed in 1994, replaced by USMCA in 2020) covered the United States, Canada, and Mexico. The European Union allows goods, services, and workers to move freely between its 27 member states. Trade agreements aim to make exporting and importing easier, cheaper, and more predictable.
Country Z exports goods worth 800 billion USD in a year and imports goods worth 950 billion USD. What is its trade balance? Is it a surplus or deficit?
Tip: when news headlines say a country "has a record trade deficit", remember that this is not automatically bad. A wealthy population that can afford to import many goods, and businesses confident enough to buy imported machinery, can both cause a deficit. Always check the wider context.
