U.S. December Core CPI Declines, Market Anticipates Earlier Rate Cuts

2025-01-16

The U.S. December Consumer Price Index (CPI) report showed core inflation falling below market expectations, alleviating fears of a resurgence in inflation. While markets still expect rates to remain unchanged in January, expectations for rate cuts this year have shifted earlier to June. Following the data release, the three major U.S. stock indices rallied, and the 10-year Treasury yield fell to approximately 4.6%.

The CPI increased by 2.9% year-over-year (prior: 2.7%) in December, according to Bureau of Labor Statistics (BLS)on January 15, marking the third consecutive monthly increase. Month-over-month rise a 0.4% (prior: 0.3%), both in line with market expectations. Core CPI rose 3.2% year-over-year (prior: 3.3%) and 0.2% month-over-month (prior 0.3%), both below market expectations of 3.3% and 0.3%, respectively.

Breaking down the component, the rise in CPI was primarily driven by a sharp increase in energy prices, which rose 2.6% month-over-month (previous 0.2%). However, core goods prices increased by just 0.1% month-over-month (previous 0.3%), failing to sustain the upward momentum from the previous month, offsetting some of the gains from energy prices. Core services prices rose 0.2% month-over-month (unchanged from the previous month), with housing services—the largest component—rising 0.3% month-over-month (unchanged from the previous month). Rent and owners’ equivalent rent also rose to 0.3% month-over-month (previous 0.2%).

On a year-over-year basis, housing services inflation fell to 4.6% (previous 4.7%), the lowest since January 2022. Rent and owners’ equivalent rent continued to decline, falling to 4.3% (previous 4.4%) and 4.8% (previous 4.9%), respectively. These trends suggest that overall core inflation will continue to decline as new lease rates moderate, though the process is expected to remain gradual.

During the Federal Reserve’s December FOMC meeting and economic forecast release, officials raised their inflation forecasts for 2024-2026, reflecting uncertainty surrounding Trump-era tariffs and immigration policies. This move aimed to preemptively anchor market expectations for a higher inflation trajectory. The January University of Michigan Consumer Sentiment Survey showed that one-year inflation expectations rose to 3.3% (previous 2.8%), while long-term inflation expectations also increased to 3.3% (previous 3.0%).

This forward-guidance strategy contributed to a more positive market reaction when core CPI and the Producer Price Index (PPI), released on January 14, came in below expectations. According to CME FedWatch data, markets maintained expectations for no rate changes in January and a single rate cut this year. However, the timing of the first rate cut has shifted slightly earlier to June (previously July), with a 30% probability of two rate cuts by year-end. Following the data release, U.S. stock indices gained between 1.5% and 2.5%, while the 10-year Treasury yield eased to around 4.6% on expectations of looser monetary policy.

Core inflation is expected to decline in the first quarter of 2025 due to high base effects and the dissipation of seasonal factors. The trajectory of core inflation in the second quarter will be critical. If core inflation continues to decline in Q2, it could deliver further positive surprises to the market and bolster expectations for an earlier Fed rate cut.
