U.S. equity index futures posted mixed results during Tuesday's session as investors digested conflicting corporate earnings and a stark deceleration in consumer price numbers. While positive bank earnings supported indices, a steep post-earnings sell-off in IBM limited broad-based gains. Macroeconomic data took center stage as the Bureau of Labor Statistics reported a 0.4% monthly decline in CPI, dragging the headline inflation rate down to 3.2% to mark the largest one-month drop since April 2020. The cooler numbers significantly lowered near-term rate expectations for July, though probability metrics still indicate a 60% chance of a September adjustment. Volume dynamics shifted heavily as a result, triggering massive call option surges in the E-mini S&P 500 and Nasdaq-100 contracts alongside notable double-digit growth in digital asset volumes.
