Global Trade War Effects: Currency Exchange Rates Analysis

What Is a Trade War and Why Does It Matter?

A trade war happens when countries charge taxes or set limits on each other’s products and services. This can hurt international trade. It may also disturb global supply chains and alter currency values. Big countries, like the United States, China, Canada, and Mexico, often run into trade problems. This causes currency fluctuations.

Trade wars make foreign exchange markets unpredictable. Investors and businesses often change their plans because of new trade policies and higher tariffs. This unpredictability can impact currency values. Therefore, it is important for businesses and individuals to watch how trade disputes affect the forex market.

What are the potential consequences of a global trade war?

A global trade war can lead to increased tariffs, higher consumer prices, disrupted supply chains, trade imbalances, and economic slowdowns. Countries may experience decreased exports and investments, rising inflation, job losses, and overall uncertainty in the global economy.

How Do Tariffs Impact Exchange Rates?

A tariff is a tax added to products coming from other countries. This makes those foreign goods more expensive. When tariffs increase, they can change a country’s trade balance and affect currency values. A country that raises tariffs might see its currency become stronger. On the other hand, a country with higher tariffs could see its currency weaken due to fewer exports and fears from investors. When tariffs go up, the country’s trade balance can change too, which can also impact how strong its currency is.

  • When a country has tariffs on imports, it can make its currency stronger. This is because more people want to buy items made locally.
  • If a country has tariffs, its currency can become weaker. This may happen due to fewer exports and lower trust from investors.

In 2018, the Trump administration added tariffs on Chinese goods. This led to trade tensions between China and the U.S. As a result, the Chinese yuan (CNY) lost value compared to the U.S. dollar (USD). This change made Chinese exports cheaper.

Year U.S. Tariffs on Chinese Imports (%) USD/CNY Exchange Rate
2018 10% 6.7
2019 25% 7.1
2020 7.5% (Phase One Deal) 6.9

How Do Trade Wars Affect Currency Fluctuations?

Currency fluctuations happen due to trade conflicts. When market sentiment is unclear, currencies tend to react fast to shifts in policies and trade talks.

  • Higher tariffs can create problems in foreign exchange markets.
  • Trade disputes lower business confidence. This impacts foreign investment and economic growth.
  • Response actions like new tariffs change currency values.

The Mexican peso (MXN) and Canadian dollar (CAD) fell sharply when the U.S. placed tariffs on steel and aluminum imported from Mexico and Canada.

Year U.S. Tariff Policy USD/MXN Exchange Rate USD/CAD Exchange Rate
2018 25% tariff on steel & aluminum 18.9 1.32
2019 USMCA trade deal discussions 19.5 1.34
2020 Tariff exemptions granted 19.0 1.30

How Do Central Banks Respond to Trade War Volatility?

Central banks play a key role in keeping currency markets stable when there are trade issues. They adjust interest rates and use monetary policies to control exchange rate volatility.

  • When a currency’s value goes down, a central bank could increase interest rates to attract investment and make it stable again.
  • If trade tensions damage economic growth, a central bank may lower interest rates to promote borrowing and spending.

The People’s Bank of China (PBOC) worked hard to prevent the yuan from losing too much value amidst trade issues with the U.S. Meanwhile, the U.S. Federal Reserve adjusted interest rates to manage inflation risks that resulted from changing trade policies.

How Do Trade Wars Influence the U.S. Dollar?

The U.S. dollar (USD) is the most important reserve currency globally. This means it is greatly influenced by any trade policy uncertainty.

  • When trade tariffs upset the global market, investors often opt for USD as a safe place to park their money. This causes the dollar’s value to rise.
  • If trade problems hurt the U.S. economy, the dollar may weaken.

During the trade war in 2018-2019, the U.S. dollar got stronger than emerging market currencies like the Chinese yuan (CNY) and the Mexican peso (MXN). Investors wanted stability during this period.

Year USD Index Value USD/CNY USD/MXN
2018 95.5 6.85 19.2
2019 98.2 7.12 19.6
2020 96.4 6.97 19.0

How Do Trade Wars Affect Emerging Market Currencies?

Trade wars greatly impact emerging market currencies. These economies really rely on exports and foreign investment.

  • When the Trump administration increased tariffs, several emerging market currencies lost value. This included the Indian rupee (INR) and the Brazilian real (BRL).
  • Countries that depend on raw materials exports had a hard time because of falling commodity prices. This caused the value of their currencies to drop.
Currency 2018 Exchange Rate (vs. USD) 2019 Exchange Rate (vs. USD)
Indian Rupee (INR) 68.4 71.2
Brazilian Real (BRL) 3.85 4.25
South African Rand (ZAR) 13.3 14.7

What Are the Effects of Trade Wars on Global Supply Chains?

Trade conflicts impact global supply chains. They can lead to higher costs and change locations for production.

  • Higher tariffs increase the prices of products brought in from other countries. This impacts local businesses.
  • Businesses may relocate their factories to avoid costs that come with tariffs.

Many companies in the U.S. have moved their manufacturing from China to countries like Vietnam and India. They chose to do this to avoid higher tariffs.

How Can Businesses and Consumers Prepare for Exchange Rate Volatility?

Businesses and people can protect themselves from changes in currency caused by the trade war by:

  • Watching trade policies: Understanding trade issues helps businesses prepare for their imports and exports.
  • Using currency protection methods: Companies use tools from the forex market to manage risks from exchange rates.
  • Checking foreign exchange services: If you send money to other countries, you should check exchange rates to avoid losing money.
