Why Central Banks Aim for Inflation: The 2% Solution

Imagine a world where the prices of goods and services never change. A gallon of milk, a tank of gas, or a movie ticket would cost the same year after year. While this might sound like an ideal scenario, the reality is that a certain level of inflation is not only normal but also necessary for a healthy economy. In this blog post, we'll explore the reasons why prices can't remain stagnant and why a little inflation is actually a good thing.

The Virtuous Cycle of Inflation

At the heart of the inflation debate is the concept of the "virtuous cycle." This cycle occurs when prices are generally rising, and people expect them to continue doing so. As a result, consumers are encouraged to spend money now on big-ticket items like cars or appliances to avoid paying more for the same product later.

Let's say you've been saving up for a new refrigerator. If you expect prices to rise by 5% over the next year, you might decide to purchase the refrigerator now rather than wait and risk paying more later.

Additionally, the cost of everyday necessities like food and clothing increases, requiring people to spend more. As companies make more money, they can employ more people and pay higher wages. This, in turn, gives consumers more money to spend, leading to increased demand and, consequently, higher prices. The cycle continues, creating a self-sustaining loop of economic growth.

The Importance of Wage Growth

For the virtuous cycle of inflation to truly benefit the economy, it's crucial that wages rise alongside prices. If your income keeps pace with inflation, you'll still be able to afford the same goods and services, even as they become more expensive.

Suppose the cost of your weekly grocery shopping increases from $100 to $105 due to inflation. If your wages also increase by 5%, you'll still be able to purchase the same amount of groceries without feeling the pinch.

However, when wage growth lags behind inflation consumers feel the strain of higher prices without the relief of increased income. This can lead to a vicious cycle, where people struggle to make ends meet, and the economy suffers as a result.

The Risks of Deflation

On the opposite end of the spectrum from inflation lies deflation, which occurs when prices fall instead of rise. At first glance, falling prices might seem like a dream come true for consumers. However, deflation can trigger a dangerous economic phenomenon known as a "deflationary spiral."

Real-world example: Imagine you're considering buying a new television. If you expect prices to drop by 10% in the next six months, you might choose to wait for a better deal. Now, apply this thinking to millions of consumers, and you can see how deflation can lead to decreased spending.

When prices fall, consumers tend to hold off on making big purchases, hoping for even lower prices in the future. As people spend less, companies make less money, leading to cost-cutting measures and layoffs. Unemployed individuals spend even less, and those who still have jobs might choose to save more to protect against financial instability. As a result, prices continue to fall, and the economy slows down.

The Difficulty of Fixing Deflation

Governments and central banks have tools to combat rising inflation, such as raising interest rates to make borrowing more expensive and slow down spending. However, fixing deflation is much more challenging.

During the Great Depression, the U.S. experienced a prolonged period of deflation. It took the outbreak of World War II, which led to massive government spending and increased employment, to finally break the deflationary spiral.

When interest rates are already low, there's little room for further reduction. If deflation takes hold, the government's options for stimulating the economy become limited, and the cost of deflation can be severe.

The Role of Inflation Targets

To avoid the pitfalls of deflation and maintain a healthy economy, many countries, set inflation targets. The most common target is around 2% per year.

While this number might seem arbitrary, it serves an essential purpose. By aiming for a small amount of inflation, central banks create a buffer against deflation. If inflation were to sit at 0%, the inherent fluctuations in the economy could easily push it into negative territory, triggering a deflationary spiral.


In a perfect world, prices would remain stable, and our money would always maintain its purchasing power. However, the reality is that a small amount of inflation is not only normal but also necessary for a healthy, growing economy. By understanding the virtuous cycle of inflation, the risks of deflation, and the role of inflation targets, we can better appreciate why prices can't simply stay the same.

Key Takeaways:

  1. A little inflation is a good thing for the economy, as it encourages spending and investment.
  2. Wage growth must keep pace with inflation for the virtuous cycle to benefit consumers.
  3. Deflation can lead to a dangerous deflationary spiral, slowing down economic growth.
  4. Governments have limited tools to combat deflation once it takes hold.
  5. Inflation targets help central banks maintain a buffer against deflation.
