The latest Consumer Price Index (CPI) report reveals that while inflation is not accelerating, it remains uncomfortably above the Federal Reserve’s 2 percent target, putting pressure on policymakers to monitor price stability. The December CPI increased 0.4 percent month over month, driven primarily by a surge in energy prices. This brings the year-over-year headline CPI to 2.9 percent, the highest in five months, according to a new analysis from Wells Fargo.
Excluding volatile food and energy components, the core CPI rose by a more modest 0.2 percent, aligning with expectations. However, the core inflation rate held steady at 3.3 percent for the seventh consecutive month, reflecting a stall in disinflationary progress. Factors such as stabilized supply chains and reduced commodity prices—key drivers of disinflation in prior months—are no longer providing significant relief.
Energy costs, including gasoline and natural gas, saw notable increases, with energy goods rising 3.7 percent in December. Seasonal dynamics in grocery promotions contributed to a lesser-than-expected price decline for food at home, further pushing the headline CPI higher.
The shelter component of the index edged back to a 0.3 percent monthly increase after slowing in November, reflecting continued upward pressure on housing costs. Meanwhile, non-housing core services inflation eased slightly, supported by a partial reversal in hotel price surges from the prior month.
The Federal Reserve faces mounting challenges as inflation remains sticky. The Fed’s preferred measure, the core Personal Consumption Expenditures (PCE) price index, rose at a more modest 0.2 percent monthly pace in December, leaving the year-over-year rate at 2.8 percent. Despite these incremental gains, inflation remains above target, requiring vigilance from policymakers.
Chair Jerome Powell and the Federal Open Market Committee (FOMC) may find it difficult to justify additional rate cuts without stronger evidence of disinflation. While the labor market has steadied, fresh inflationary pressures—such as higher tariffs and resilient consumer spending—pose risks.
Wells Fargo economists Sarah House and Aubrey Woessner highlighted the role of new trade policies in exacerbating inflationary pressures. Higher tariffs are likely to leave businesses with little choice but to pass costs on to consumers, while a cooling labor market and more price-conscious consumers may counterbalance these forces to some extent.
The December CPI data underscore the uphill battle to bring inflation back to the Fed’s 2 percent target. As policymakers grapple with these persistent challenges, the 2025 economic outlook appears increasingly complex. Stakeholders will watch closely for signs of renewed progress in disinflation and the Fed’s response to an economic environment marked by price stickiness and shifting policy dynamics.
