U.S. stock futures declined Tuesday as investors braced for January's consumer-price index report. Dow Jones Industrial Average futures fell around 100 points, signaling a cautious open on Wall Street. The inflation data, due this morning, comes amid heightened market sensitivity to price pressures and Federal Reserve policy.

Traders are particularly focused on whether December's cooling inflation trend continued into January. Recent economic data has shown mixed signals, with some indicators suggesting persistent price pressures despite overall moderation. The CPI report could influence expectations for future interest rate decisions.

The market's reaction underscores how inflation data remains a critical driver of investor sentiment. With the Federal Reserve closely monitoring price trends, today's numbers could impact both equity markets and bond yields. Investors are weighing the potential for sustained economic growth against the risk of persistent inflation requiring tighter monetary policy.
