In the world of global financial markets, one of the most anticipated economic data releases each month is the United States inflation report. Every time inflation data is published, currency, gold, stock, and bond markets can move aggressively within just a few minutes.
Most investors usually focus more on the Consumer Price Index (CPI) because this data often triggers significant volatility in the markets. But in reality, the Federal Reserve (Fed) pays more attention to another less popular inflation indicator, which is the Core PCE.
The question is, why does the Fed trust Core PCE more than CPI? Why is this difference so important for traders and investors to understand?
What is CPI?
CPI or Consumer Price Index measures the changes in prices of goods and services paid by consumers daily. It includes prices of food, fuel, rent, transportation, medical care, and various other basic necessities.
Because this data is released earlier each month, CPI often serves as the first indicator of the current inflation situation in the United States. That is why the market usually reacts very aggressively when the CPI figures are higher or lower than expected.
If CPI rises sharply, it will support the USD currency and US government bond yields. However, commodity and stock markets tend to decline.
In other words, CPI is a ‘market mover’ because it has a very large emotional and sentiment impact on global investors.
Why Does the Fed Focus More on Core PCE?
Although CPI is more popular, the Fed actually uses the Core PCE or Personal Consumption Expenditures Price Index more as the main reference for their monetary policy.
Core PCE is considered more accurate because its data scope is broader as it closely examines changes in consumer behavior, features less volatile figures, and is more flexible in measuring actual inflation.
Unlike CPI, Core PCE is also less influenced by sudden changes in food and energy prices, which are often temporary.
Why Do Traders Need to Understand This Difference?
Many traders only look at CPI because its impact on the market is very immediate. But understanding Core PCE can help investors read the Fed’s true direction more accurately.
In the current situation, the Fed remains very cautious because they do not want to repeat the mistakes of the 1970s inflation era, where interest rates were cut too early before inflation truly subsided.
So even though the market is very obsessed with CPI, the actual interest rate decisions still largely depend on how Core PCE moves in the coming months.
