US equity markets are preparing for a volatile session as traders await the release of June consumer price index (CPI) data, a key indicator that will shape expectations for Federal Reserve interest rate policy.

The data release coincides with the start of the second-quarter earnings season, creating a complex backdrop for investors navigating both macroeconomic signals and corporate fundamentals.

The June CPI print is widely viewed as a critical data point for determining the trajectory of monetary policy.

A hotter-than-expected reading could dampen hopes for near-term rate cuts, while a cooler figure might reinforce the market's current pricing of easing.

This sensitivity is heightened by the upcoming Federal Reserve policy meeting on July 29, where officials will assess the latest inflation trends against labor market conditions.

Simultaneously, Wall Street's focus is shifting toward corporate earnings, with major financial institutions including JPMorgan Chase set to report results.
