Does War Affect Interest Rates?

War has been a significant factor in shaping global economic trends, and one of the key aspects that is often affected is interest rates. But does war really impact interest rates, and if so, how?

What are Interest Rates?

Before diving into the relationship between war and interest rates, let’s define what interest rates are. Interest rates are the percentage at which banks and other financial institutions lend and borrow money. They are used to control inflation, stabilize the economy, and encourage borrowing and spending. Interest rates are usually set by central banks, such as the Federal Reserve in the United States.

Theoretical Link Between War and Interest Rates

From a theoretical perspective, war can affect interest rates in several ways:

• Increased borrowing needs: During a war, governments often need to borrow more money to finance their military efforts, which can lead to an increase in the demand for credit and, subsequently, higher interest rates.
• Risk and uncertainty: War creates uncertainty and increases the risk of economic disruption, which can lead to a higher premium for investors, driving up interest rates.
• Inflationary pressures: War can disrupt global supply chains, leading to shortages and price increases, which can drive up inflation and lead to higher interest rates.
• Weakening of global economic confidence: War can weaken global economic confidence, leading to reduced investment, lower consumption, and lower economic growth, which can lead to higher interest rates.

Historical Examples of War Affecting Interest Rates

Let’s take a look at some historical examples to see if these theoretical links hold up:

World War I (1914-1918)

During World War I, the United States government borrowed heavily to finance its war efforts, leading to an increase in the federal debt from $1.6 billion to $25.4 billion. This increase in borrowing needs led to a rise in interest rates, with the yield on the 10-year US Treasury bond increasing from 3.2% to 5.1% during the war period.

World War II (1939-1945)

During World War II, the US government continued to borrow heavily, but the Federal Reserve kept interest rates low to finance the war effort. The yield on the 10-year US Treasury bond remained relatively low, ranging from 1.2% to 2.2% during the war period.

The War in Iraq (2003-2011)

During the Iraq War, the Federal Reserve kept interest rates low to stimulate the economy, which was experiencing a recession. The yield on the 10-year US Treasury bond remained relatively low, ranging from 1.3% to 3.4% during the war period.

The 2008 Global Financial Crisis and the War in Afghanistan

During the 2008 global financial crisis, the Federal Reserve kept interest rates low to stimulate the economy, which was experiencing a severe downturn. The war in Afghanistan also increased the demand for credit and led to an increase in interest rates. The yield on the 10-year US Treasury bond rose from 2.6% to 4.1% during the crisis period.

The Russian Invasion of Ukraine (2022)

The ongoing Russian invasion of Ukraine has led to a surge in oil prices, increased global inflationary pressures, and weakened global economic confidence. In response, the Federal Reserve has raised interest rates several times to combat inflation and maintain economic stability. The yield on the 10-year US Treasury bond has risen from 1.7% to 2.9% since the start of the conflict.

Conclusion

In conclusion, war can indeed affect interest rates, although the relationship is complex and influenced by various factors. During times of war, governments may need to borrow more money, leading to an increase in the demand for credit and higher interest rates. Additionally, war can create uncertainty, inflationary pressures, and weaken global economic confidence, all of which can drive up interest rates. However, the extent to which war affects interest rates depends on various factors, including the nature and duration of the conflict, the government’s fiscal policy, and the response of central banks.
