ดัชนี Core PCE Price Index คืออะไร?
When it comes to monitoring the economic condition and the Federal Reserve’s decisions, one key indicator that traders and investors should pay close attention to is the Core PCE Price Index. This index is an important measure of inflation, directly influencing interest rate adjustments and financial market movements. Let’s take a look at what the Core PCE is and why it’s an indicator everyone needs to know!
Core PCE Price Index (Personal Consumption Expenditures) Or in Thai, it is called Core Personal Consumption Expenditures (PCE) Price Index
It is an index used to measure the changes in prices of goods and services consumed by people in the U.S., excluding two highly volatile categories: food and energy. These two groups are excluded because their prices tend to fluctuate rapidly, which can make inflation measurement less clear.

Therefore, the Core PCE helps the Fed and analysts gain a clearer long-term view of price changes in various goods, allowing them to better understand the true inflation occurring in the economy.
Why is the Core PCE important?
The reason Core PCE is important is because it is an indicator used by the U.S. Federal Reserve (Fed) to assess inflation. This affects the Fed’s decision to adjust interest rates, which in turn influence the movements of global financial markets, including the stock market, bond market, and currency market.
A higher Core PCE figure indicates rising inflation, which may lead the Fed to decide to raise interest rates to reduce economic pressure. Conversely, if the Core PCE is low or shows signs of deflation, the Fed may choose to lower interest rates to stimulate the economy.
How does the Core PCE affect financial markets?
Changes in the Core PCE directly affect both the US dollar and gold prices. Let’s take a closer look at how this happens.
1. Impact on the US Dollar (USD)
- Core PCE Increases: If the figure comes out higher than expected, it indicates that inflation is rising rapidly. This may lead the Fed to decide to raise interest rates to reduce economic pressure, causing the US dollar to strengthen because investors worldwide will see the dollar as an asset with higher returns.
- Core PCE Decreases: If the figure is lower than expected, it means inflation is not rising or there may be deflation. This could cause the Fed to keep interest rates steady or lower them. As a result, the US dollar will weaken because lower interest rates make holding dollars less attractive to investors.
2. Impact on Gold Prices
- Core PCE increases: If this number rises and interest rates are likely to increase, gold is usually negatively affected. Gold prices may decline because investors tend to sell gold to hold other assets with higher returns, such as bonds or stocks.
- Core PCE decreases: If the number comes in lower than expected, gold may rise. When interest rates are kept steady or lowered, investors often seek safe-haven assets like gold, which can lead to higher gold prices.
Why do traders need to pay attention to the Core PCE?
For traders, whether you trade in the Forex, stock, or gold markets, monitoring the Core PCE figure is extremely important because it indicates inflation trends and the central bank’s interest rate decisions, which significantly impact market movements.
A high Core PCE figure may signal a stronger US dollar, while a low figure could indicate a weaker dollar and a potential rise in gold prices. Traders who understand and follow this data have better opportunities to profit from market movements.
Conclusion
Core PCE is an important index used to measure inflation in the United States and serves as a key indicator that the Fed relies on to make decisions about adjusting interest rates. Because this figure directly impacts the US dollar and gold prices, traders and investors should closely monitor this news to better assess market trends and make informed investment decisions.
