Which Factors Can Influence a Country's Balance of Trade?

Reading time: 7 minutes

The balance of trade is the difference between the value of exports and the value of imports flowing in and out of a country’s economy. When a country exports more than it imports, it has a trade surplus; conversely, when imports exceed exports, it is a trade deficit. A trade surplus is typically a sign that a country’s exports are highly demanded in the global economy. A trade deficit can signal a strong consumer economy but may also mean the nation is not producing enough to meet domestic demand or its goods aren’t globally competitive.

This balance reflects a nation’s competitiveness in the global market and offers insight into its economic health. It’s also a key component of a broader macroeconomic measure, the balance of payments, which is the aggregate value of all payments made to and from a country’s economy.

Factors Influencing the Balance of Trade

  • Currency, Inflation, and Foreign Exchange Reserves

One of the most influential factors in the balance of trade is exchange rates. If a country’s currency is strong, its exports become more expensive for foreign buyers in their local currency, resulting in reduced demand. A strong domestic currency also makes imports cheaper, encouraging domestic consumers to import more goods and potentially worsening a trade deficit. The opposite is true for a weak currency, where exports become cheaper and more competitive in the global market, and imports become more expensive.

Inflation also plays a role in a country’s trade balance. Inflation can make production more expensive as the cost of inputs rises, making them less competitive in global trade. Lastly, foreign exchange reserves are typically necessary to import machinery that makes a nation more productive. Without adequate reserves, its goods may cost more to produce and thus be more expensive. Low foreign currency reserves also make managing currency fluctuations and inflation trickier.

  • Economic Policies of the Nation

A country's economic and trade policies can significantly shape its trade landscape. Tariffs and taxes on imported goods can protect domestic industries but may reduce imports and trigger retaliation.

Subsidies can give domestic producers an edge, allowing them to offer competitive prices in international trade. Quotas, limits on the number or value of certain imports, help control trade volume.

Moreover, trade barriers or free trade agreements can either restrict or open up markets. Policymakers can use these tools to address trade imbalances. In recent years, American politicians have imposed tariffs on billions of dollars worth of Chinese goods, alleging unfair trade practices, prompting China to retaliate and place tariffs on US exports.

  • Global Economic Environment

When the world economy thrives, there's a ripple effect: demand surges, boosting exports of goods for many countries. However, during global recessions, reduced consumer spending can lead to declining imports and exports internationally.

Additionally, the economic health of a nation’s key trading partner nations matters immensely. For instance, a recession in Asia would impact Australia’s positive balance of trade, given that Asia is its main exporting partner.

  • Domestic Production Capabilities and Resources

A domestic economy’s production strength often hinges on two key factors: comparative advantage and access to raw materials.

The comparative advantage speaks to a country's ability to specialise in certain goods at a lower opportunity cost than others (opportunity cost is defined as ‘the next best alternative foregone’). For instance, if one nation can produce wine at a lower opportunity cost more efficiently than wheat, it will lean into wine production. The absolute advantage, on the other hand, is straightforward, which simply looks at the production costs behind a good (the ability of a country to produce greater quantities of a good using the same inputs as another country. 

Access to raw materials and resources is also crucial. Nations abundant in resources like oil, minerals, or agricultural products typically export these to foreign countries lacking these endowments, boosting their trade balance.

  • Demand

Driving all foreign trade is demand, governed significantly by consumer tastes. Oil, for example, is in constant demand at a huge scale. Nations that export oil are likely to have trade surpluses, while those with virtually no oil deposits, like Japan, are predisposed to trade deficits.  

Broader consumer preferences, driven by a wide variety of factors, also shape demand. As tastes evolve over a given period of time, the goods a country imports and exports change. For instance, the growing demand for battery-powered technology may increase a lithium producer’s net exports.

  • Political Stability and Relations

A politically stable nation is, generally speaking, a trustworthy one, meaning trading partners are more comfortable doing business with it. Economic growth, as measured by Gross Domestic Product (GDP), is typically more stable in these countries, and their climates are often more favourable for foreign investors.

Foreign investment is important because it can lead to increased production, job creation, and technological advancements—all of which can contribute to an improved balance of trade. Stable political ties can also pave the way for mutually beneficial trade agreements, which may increase either nation’s exports or lower their import costs.

The Bottom Line

In essence, a country’s balance of trade is driven by a wide variety of factors, including many out of its control. Understanding this complex interplay can help traders and investors grasp where an economy stands on the world stage and where its strengths and weaknesses lie. In turn, it can help market participants make better-informed decisions and navigate the shifting tides of financial markets more confidently.
