Why does the U.S. Consumer Price Index (CPI) have a significant impact on the market?

There are several reasons why the U.S. Consumer Price Index (CPI) has a significant impact on the market. Here is a detailed explanation:

Impact on Inflation and Monetary Policy:

• The CPI is an indicator that shows the rate of price increases and affects the monetary policy of central banks. If the inflation rate exceeds the central bank's target, it could prompt monetary tightening (interest rate hikes). This is because there might be a need to adjust monetary policy to curb price increases.
• In the foreign exchange market, there is a causality that if U.S. interest rates rise, the dollar strengthens. Conversely, if interest rates fall, the dollar weakens.

Relation to Market Expectations:

• The CPI is an important economic indicator for market participants and provides clues for predicting the movement of prices.
• Since price increases can also affect the economy, the market pays close attention to the CPI.
• Especially if the path to the U.S. inflation target of 2% is long, the CPI will continue to be one of the most closely watched economic indicators.

Market Reaction:

• After the CPI announcement, significant price movements can be seen in the foreign exchange and stock markets.
• For example, if the CPI exceeds expectations, the dollar might rise, and the stock market could react accordingly.

In summary, the CPI is an important indicator that shows the movement of prices, and market participants react sensitively to its movements.
