Effects of Inflation on Stock Prices

Effects of Inflation in Stock Prices

A direct correlation exists between inflation and stock prices. Theoretically, inflation should not affect stock prices because companies can simply raise their prices to make up for the increased cost to produce goods and services.

In reality, companies competing globally cannot raise their prices for fear of losing business to competitors. These companies are negatively affected by inflation. Investors must understand the importance of inflation to stock prices to know the impact inflation will have on their investments.

  • Corporate Profits

Inflation negatively affects corporate profits. Stock prices are a direct reflection of corporate net earnings. Many businesses cannot change their prices to reflect increased cost. Companies typically pass the rising cost of production to customers in several stages instead of all at once.

While this process is taking place, companies must endure the increased cost to deliver products and services to consumers. Businesses are also hesitant to increase the price of goods and services out of fear of consumers’ reactions as loss of consumers will reduce corporate profits and negatively affect the value of the company’s stock.

  • Economy

Inflation often causes the government to restrict monetary policy. It typically increases interest rates in an effort to control inflation. Increased interest rates make borrowing money more expensive, which decreases the amount of money circulating through the economy.

A decrease in consumer spending negatively affects companies’ earnings, and consequently stock prices. Increased interest rates also affect business investments, which are critical to the long-term growth of a company.

  • Investor Confidence

Inflation can last for a short or long period of time. The uncertainty about inflation affects investor confidence. Some investors may choose to sell their shares if they believe inflation will stick around for the long-term. If too many investors sell their shares, it can cause stock prices to decline because supply is greater than demand. Investors who continue to invest in stocks require a higher rate of return because of the associated risk. To achieve higher returns, stock prices must decrease.

  • Global Market

While some companies can react to inflation by raising their prices, others who compete in a global market may find it difficult to stay competitive with foreign producers who don’t have to raise prices due to inflation. More importantly, inflation takes from investors by raising prices with no corresponding increase in value.

This means company’s financials are over-stated by inflation because the numbers (revenue and earnings) rise with the rate of inflation in addition to any added value generated by the company.


The effect of inflation on stock prices depends on the severity of inflation in the economy. The measurement of inflation can show the severity of inflation.
