The Bureau of Labor Statistics delivered its verdict on December inflation Tuesday morning, and the news was neither relief nor alarm—instead, confirmation that the path back to price stability remains a slow grind. The Consumer Price Index rose 2.7% year-over-year in December, matching November's reading and meeting economist expectations.

Core inflation, which strips out volatile food and energy prices, also came in at 2.7% annually, with a month-over-month increase of approximately 0.26%. These figures leave the Federal Reserve in familiar territory: inflation that's trending in the right direction but still uncomfortably above the central bank's 2% target.

Why This Report Matters More Than Most

December's CPI release carries unusual weight for several reasons that extend beyond the headline numbers:

  • Data Quality Reset: The October CPI collection was disrupted by a government funding lapse, creating noise in recent readings. December's data offers the first clean checkpoint since that disruption, allowing economists to more accurately assess the inflation trend.
  • Fed Credibility Crisis: With the Department of Justice investigation into Fed Chair Jerome Powell dominating headlines, any inflation surprise would amplify questions about the central bank's ability to fulfill its mandate.
  • Rate Cut Expectations: Markets have priced in two Fed rate cuts for 2026, beginning in June. Today's report will either validate that view or force a recalibration.

"The December data confirms what we've been seeing—inflation is no longer accelerating, but the last mile back to 2% is proving stubborn. The Fed has room to be patient, but not room to declare victory."

Breaking Down the Numbers

Within the headline figures, several categories tell a more nuanced story:

Shelter costs remain the primary driver of elevated core inflation, though the rate of increase has moderated from 2024 peaks. Housing economists expect shelter inflation to continue declining gradually as lower market rents filter into the CPI's lagged methodology.

Energy prices declined in December, providing modest relief to consumers after volatile swings earlier in 2025. Gasoline prices fell month-over-month, contributing to the relatively benign headline reading.

Food prices rose modestly, with grocery inflation running at roughly 2.4% year-over-year according to private-sector data. The normalization of egg prices following 2025's bird flu crisis has helped contain food inflation.

Services inflation remains the Fed's primary concern. Categories like insurance, healthcare, and dining out continue to show price increases above the overall inflation rate, reflecting ongoing labor cost pressures in service industries.

What It Means for Fed Policy

The December CPI report is unlikely to significantly alter the Federal Reserve's near-term plans. The Federal Open Market Committee meets January 28-29, and markets overwhelmingly expect no change to the federal funds rate at that meeting.

The more interesting question is what comes next. Fed Governor Stephen Miran has advocated for 150 basis points of rate cuts in 2026, citing manageable inflation and softening labor market conditions. Other Fed officials favor a more cautious approach, pointing to inflation that remains above target.

Today's data supports the cautious camp. With inflation stuck at 2.7%, aggressive rate cuts would risk reigniting price pressures—particularly given fiscal policy uncertainty and potential tariff impacts on import prices.

Market Reaction

Financial markets showed a muted initial response to the in-line CPI reading. Stock futures ticked slightly higher as the absence of an upside surprise removed one potential headwind for risk assets. Treasury yields were little changed, with the 10-year note holding near 4.18%.

The dollar, which has weakened in recent days amid the Fed turmoil, stabilized following the release. Currency traders had been watching for any inflation surprise that might complicate the Fed's policy path.

The Consumer Perspective

For American households, the December CPI offers a reminder that while the inflation crisis of 2022-2023 has faded, prices aren't falling—they're just rising more slowly. The cumulative price increase since 2020 exceeds 20% for many essential categories, and wages have only partially kept pace.

The good news: real wage growth has turned positive, meaning most workers are seeing purchasing power gains. The bad news: years of above-target inflation have permanently raised the price level, and no amount of Fed policy will bring prices back to pre-pandemic levels.

Looking Ahead

The January CPI report, due in mid-February, will carry even greater significance as the Fed approaches its first opportunity to cut rates in 2026. If inflation continues to hover near current levels, the central bank may opt to hold rates steady longer than markets currently expect.

For investors, the December report suggests a familiar playbook: moderate inflation supports equity valuations, but the Fed's flexibility to cut rates aggressively remains constrained. The "higher for longer" interest rate environment that defined 2024-2025 may be moderating, but it hasn't ended.

The inflation genie isn't quite back in the bottle—but at least it's no longer running wild.
