The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by consumers for a basket of goods and services. It is calculated by the Bureau of Labor Statistics (BLS) as their measure of inflation. It is usually released around the second Wednesday of every month and references the prior month.
 

What is CPI?

The index is calculated using the prices of a fixed basket of goods and services, with the base period prices set at 100. To determine the index for the current period, the prices are compared to those in the base period. The percentage change in the index from the base period is then used to gauge inflation.

The Consumer Price Index (CPI) tracks price changes for a fixed set of goods and services. This basket encompasses categories like food and beverages, housing, clothing, transportation, medical care, recreation, education, communication, and other items. The Bureau of Labor Statistics (BLS) updates this market basket periodically to reflect shifts in consumer spending patterns.
 

What impact does the CPI have on financial markets?

CPI can influence monetary policy, interest rates and the value of the currency. It also impacts wages, consumer spending and economic growth. High inflation can lead to economic instability, while low or negative inflation (deflation) can indicate a weak economy.

1.     Interest Rates and Monetary Policy
The Consumer Price Index (CPI) is a crucial economic indicator that impacts the Federal Reserve’s interest rate decisions. When inflation is high (indicated by a rising CPI), the Fed may increase interest rates to cool down the economy. Conversely, low inflation could lead the Fed to lower interest rates to encourage economic growth. Fluctuations in interest rate expectations driven by CPI data can affect bond and stock prices as investors adjust their forecasts.

2.     Bond Markets
The Consumer Price Index (CPI) significantly impacts bond yields (as illustrated by the red line on the chart below). Higher inflation often leads to increased yields, as investors seek greater compensation for the reduced purchasing power of future bond payments. With rising CPI, the demand for Treasury Inflation-Protected Securities (TIPS) may also grow, as these securities provide a safeguard against inflation.

3.     Stock Markets
Inflation affects corporate earnings by raising costs for companies, which can squeeze profit margins unless they are able to pass these costs onto consumers. Different sectors respond differently to inflation: consumer staples and utilities may perform better in high-inflation environments due to their ability to transfer costs to consumers, while growth sectors like technology might struggle due to higher discount rates on future earnings.

4.     Currency Markets
Higher inflation can lead to a decrease in a currency's value as purchasing power diminishes. However, if inflation drives interest rates higher, the currency might appreciate due to increased demand for investments that offer higher returns. Currency traders keep a close eye on CPI data to forecast central bank policies and make informed trading decisions.

5.     Commodity Markets
Commodities such as gold and oil are highly sensitive to inflation data. Gold is often viewed as a hedge against inflation, so a rising CPI data might boost demand for gold. Inflation can also influence oil prices both directly, through increased production costs, and indirectly, through shifts in monetary policy. Since oil is a key input for transportation, higher oil prices can lead to increased transport costs, affecting the prices of goods. Additionally, higher oil prices can lead to increased producer prices, which may drive workers to demand higher wages.
