What Are Terms of Trade (TOT)?

Terms of trade (TOT) represent the ratio between a country's export prices and its import prices. How many units of exports are required to purchase a single unit of imports? The ratio is calculated by dividing the price of the exports by the price of the imports and multiplying the result by 100.

More capital is leaving the country than is entering the country when a country’s TOT is less than 100%. When the TOT is greater than 100%, the country is accumulating more capital from exports than it is spending on imports.

How Do Terms of Trade (TOT) Work?

The TOT is used as an indicator of a country’s economic health, but it can lead analysts to draw the wrong conclusions. Changes in import prices and export prices impact the TOT and it's important to understand what caused the price increases or decreases. TOT measurements are often recorded in an index for economic monitoring purposes.

An improvement or increase in a country's TOT generally indicates that export prices have gone up as import prices have either maintained or dropped. Conversely, export prices might have dropped but not as significantly as import prices. Export prices might remain steady while import prices have decreased or they might have simply increased at a faster pace than import prices. All these scenarios can result in an improved TOT.

Fast Facts

  • The ratio is calculated by dividing the price of the exports by the price of the imports and multiplying the result by 100.
  • More capital is leaving the country than is entering the country when a country’s TOT is less than 100%.
  • An improvement or increase in a country's TOT generally indicates that export prices have gone up as import prices have either maintained or dropped.

A Real World Example

Developing countries experienced increases in their terms of trade during the commodity price boom in the early 2000s. They could buy more consumer goods from other countries when selling a certain quantity of commodities, such as oil and copper.

In the past two decades, however, a rise in globalization has reduced the price of manufactured goods. Industrialized countries' advantage over developing countries is becoming less significant.

Factors Affecting Terms of Trade

A TOT is dependent to some extent on exchange and inflation rates and on prices. A variety of other factors influence the TOT as well and some are unique to specific sectors and industries.

Scarcity – the amount of goods available for trade – is one such factor. The more goods a vendor has available for sale, the more goods it will likely sell, and the more goods that vendor can buy using capital obtained from sales.

The size and quality of goods also affects the TOT. Larger and higher-quality goods will likely cost more. If goods sell for a higher price, a seller will have additional capital to purchase more goods.

Fluctuating Terms of Trade

A country can purchase more imported goods for every unit of export that it sells when its TOT improves. An increase in the TOT can therefore be beneficial because the country needs fewer exports to buy a given number of imports.

It might also have a positive impact on domestic cost-push inflation when the TOT increases because the increase is indicative of falling import prices in relation to export prices. The country’s export volumes could fall to the detriment of the balance of payments, however.

The country must export a greater number of units to purchase the same number of imports when its TOT deteriorates. The Prebisch-Singer hypothesis states that some emerging markets and developing countries have experienced declining TOTs because of a generalized decline in the price of commodities relative to the price of manufactured goods.
