Two key economic reports set to be released this week could have a significant impact on the future of the Federal Reserve's interest rate policy. The first report is the U.S. gross domestic product (GDP) for the final quarter of 2023, which is expected to show growth at a 1.7% pace. This would be the slowest expansion since a decline in Q2 of 2022.

In addition, the Commerce Department will release the personal consumption expenditures price index, also known as the core PCE, which serves as a crucial inflation gauge for the Federal Reserve. Economists are forecasting a 0.2% monthly increase and a 3% annual growth in core PCE prices, excluding food and energy components.

The markets are closely watching these figures as they move towards the Fed's 2% inflation target, a milestone that has not yet been reached. Federal Reserve officials have indicated that their rate decisions are data-driven and anchored towards achieving their inflation target.

Market sentiment has shifted in response to recent data, including a 0.6% increase in consumer spending for December and a decrease in initial jobless claims. Expectations for a rate cut at the Fed's March meeting have decreased, along with a decrease in the anticipated number of rate cuts for the year.

As the Federal Reserve prepares to hold interest rates steady, there is speculation about potential rate cuts in the first half of 2024 if inflation falls faster than expected. However, there has been no indication of a planned rate cut for March. Federal Reserve policymakers are approaching rate decisions cautiously due to historical errors in the past.
