Markets edge near records as cooler CPI eases inflation fears

U.S. equity benchmarks opened near record levels after the Labor Department’s Bureau of Labor Statistics reported a modest December rise in the Consumer Price Index, a set of readings that softened immediate inflation pressures and prompted a measured market response. Headline CPI rose 0.3% month over month and 2.7% year over year, while core CPI, which excludes food and energy, increased 0.2% month over month and 2.6% year over year, below the Dow Jones consensus that had anticipated a 0.3% monthly core gain and 2.8% annual pace.

The cooler-than-expected core print produced an intraday lift for risk assets and helped pare earlier losses, with markets adopting a mixed but relatively calm tone. Investors drew two signals from the data: inflation momentum appeared to be abating from the highs of 2025, yet price growth remains above the Federal Reserve’s 2% target, leaving room for caution in the near term. Fed funds futures, via the CME FedWatch tool, priced in two quarter-percentage-point cuts beginning in June 2026, a path that reflects markets’ view that easing is likely later this year rather than immediately.

The CPI release arrived days after a December jobs report that market participants described as showing a "somewhat weaker, yet stable" labor market. Taken together, the labor and price data present a mixed signal for policymakers: softer job growth supports patience on rate cuts, while cooling core inflation reduces urgency to keep policy exceptionally restrictive. That balance helps explain why futures scaled back some earlier volatility rather than prompting a decisive market rally or rout.

The backdrop to the trading session included an all-time closing high for the S&P 500 and Dow Industrials in the prior session, and a record for the Russell 2000 small-cap index, underscoring broad participation in the recent advance. Market breadth was supported by positive corporate news: JPMorgan Chase shares rose about 1% after the bank reported fourth-quarter adjusted earnings of $5.23 per share on $46.77 billion in revenue, beating analyst projections and highlighting resilience in trading revenue. Defense and aerospace names moved sharply after L3Harris Technologies said it will pursue an initial public offering of its missile solutions business in the second half of 2026; the stock jumped about 13%.

Geopolitical developments added volatility to commodity markets. Oil prices spiked after President Donald Trump canceled all meetings with Iran and told protesters that "help is on its way," following a statement that any country doing business with Iran would face a 25% tariff "on any and all business being done" with the U.S. Those moves raised near-term supply risk perceptions and pressured energy-sensitive sectors.

Longer-term context matters for interpreting the December data. Inflation remains above the Fed’s target, but the flattening of price gains through late 2025 marks an improvement from earlier in the year, when tariff actions and supply disruptions contributed to sharper price increases. As TradeStation strategist David Russell put it, Americans were "starting to see relief on prices after a long wait since the pandemic."

For markets, the December CPI offered reassurance without decisively shifting the policy outlook. Investors and policymakers will be watching incoming data in the coming months, especially wage growth and services inflation, to judge whether the modest easing in core CPI represents a durable trend or a temporary pause.
