The balance of trade is the value of a country's exports minus its imports. It's the most significant component of the current account. It measures a country's net income earned on international assets. The current account also includes all payments across borders. The trade balance is the easiest to measure. That's because all goods and many services must pass through the customs office.

The current account is part of a country's balance of payments.

It measures all international transactions.

How to Calculate It

A country's trade balance equals the value of its exports minus its imports. Exports are goods or services made domestically and sold to a foreigner. That includes a pair of jeans you mail to a friend overseas. It could also be signage a corporate headquarter transfers to its foreign office. If the foreigner pays for it, then it's an export.

Imports are goods and services bought by a country's residents but made in a foreign country. It includes souvenirs purchased by tourists traveling abroad. Services provided while traveling, such as transportation, hotels, and meals, are also imports. It doesn't matter whether the company that makes the good or service is a domestic or foreign company. If it was purchased or made in a foreign country, it's an import.

When exports are larger than imports, it's a trade surplus. Most nations view that as a favorable trade balance.

When exports are less than imports, it's a trade deficit. Countries usually regard that as an unfavorable trade balance. But sometimes a favorable trade balance, or surplus, is not in the country's best interests. For example, an emerging market should import to invest in its infrastructure. It can run a deficit for a short period with this goal in mind.


Favorable Trade Balance

Most countries try to create trade policies that encourage a trade surplus. They consider a surplus a favorable trade balance because it's like making a profit as a country. Nations prefer to sell more products and receive more capital for their residents. It translates into a higher standard of living. Their companies also gain a competitive advantage in expertise by producing all the exports. They hire more workers, reducing unemployment and generating more income.

To maintain this favorable trade balance, leaders often resort to trade protectionism. They protect domestic industries by levying tariffs, quotas or subsidies on imports. That doesn’t work for long. Soon other countries retaliate with their protectionist measures. A trade war will reduce international trade for all nations.

But sometimes a trade deficit is the more favorable balance of trade. It depends on where the country is in its business cycle. For example, Hong Kong has a trade deficit. But many of its imports are raw materials that it converts into finished goods and then exports. That gives it a competitive advantage in manufacturing and finance. It creates a higher standard of living. Canada's slight trade deficit is a result of its economic growth.

Its residents enjoy a better lifestyle afforded by diverse imports.

Romania's former dictator, Nicolae Ceausescu, created a trade surplus that hurt his country. He used protectionism to bolster domestic industries. He also forced Romanians to save instead of spending on imports. That resulted in such a low standard of living that the people forced him out of office.

Unfavorable Trade Balance

Most of the time, trade deficits are an unfavorable balance of trade. As a rule, countries with trade deficits export raw materials. They import a lot of consumer products. Their domestic businesses don't gain the experience needed to make value-added products. Their economies become dependent on global commodity prices. Such a strategy also depletes their natural resources in the long run.

Once in a while, a trade surplus is an unfavorable trade balance.

 China and Japan have both become dependent on exports to drive economic growth. They must purchase significant amounts of U.S. Treasurys to keep the dollar's value high and the value of their currencies low. That's how they keep their exports competitively priced and maintain their trade surplus. But this export-driven strategy means they rely on U.S. customers and U.S. foreign policy. In addition, their domestic market is weak. Chinese and Japanese citizens must save to provide for their old age since the governments don't have strong social services. 

Difference Between Balance of Trade and Balance of Payments

The balance of trade is the most significant component of the balance of payments. The payments balance adds international investments plus net income made on those investments. 

A country can run a trade deficit, but still have a surplus in its balance of payments. Foreigners invest in the country's growth by loaning to businesses. They also buy government bonds and hire workers from that country. If the other components of the balance of payments are in a large enough surplus, it will offset a trade deficit.
