Core Inflation Persists Despite Fed Rate Cuts
The latest Consumer Price Index (CPI) data reveals that inflation pressures remain stubbornly persistent as 2025 draws to a close. Annual inflation stands at 2.7%, still above the Federal Reserve's 2% target, with shelter costs and tariff impacts keeping price pressures elevated.
Core inflation, which excludes volatile food and energy prices, has moderated to 2.6% year-over-year—the lowest reading since March 2021. However, monthly increases continue at a pace that suggests the "last mile" to the Fed's 2% target remains challenging.
Services Sector Drives Persistent Price Growth
The sticky nature of current inflation is largely attributed to services inflation, particularly housing costs. The shelter index rose 0.4% in December and was the largest factor in the monthly increase, with annual shelter inflation running at 3.2%.
Food prices accelerated, with the food index increasing 0.7% over the month. Both food at home and food away from home contributed equally to the increase. Energy prices rose 0.3% in December after periods of volatility earlier in the year.
Tariff Impact on Inflation
Trade policy has materially affected inflation readings. According to economist Mark Zandi, "I think were it not for the tariffs, we would have been back to target already." Tariffs have pushed up inflation by approximately half a percentage point, complicating the Fed's path back to its 2% target.
Prices slowed notably for used cars and trucks (1.6% versus 3.6% in November) and household furnishings and operations (4% versus 4.6%), providing some offset to the persistent shelter inflation.
Data Collection Challenges
The inflation data comes after a 43-day government shutdown that lasted from early October until mid-December, which disrupted previous CPI reports. Economists have cautioned that the process used by the Bureau of Labor Statistics to carry-forward data could impart a downward bias on CPI inflation readings through April 2026.
Market Reaction and Fed Policy Implications
Markets continue to digest the implications of persistent inflation for Federal Reserve policy. With the Fed having cut rates three times in 2025, the question of additional easing in 2026 depends heavily on continued progress toward the 2% target.
Fed fund futures suggest investors expect rates to remain on hold until at least April, when the Fed may resume reductions if inflation continues moderating.
Why This Matters for Investors
Persistent inflation carries significant implications for investment portfolios across asset classes:
- Bond investors face continued duration risk as elevated inflation keeps pressure on real yields
- Equity investors should focus on companies with pricing power and strong balance sheets
- Precious metals continue to benefit from inflation hedging demand
- TIPS may offer attractive hedging opportunities given sticky core inflation
The report reinforces the importance of maintaining diversified portfolios with inflation hedges, including commodities exposure and dividend-growth stocks from sectors with historically strong pricing power.
