April CPI expected to spike to 3.9%, signaling early supply-driven inflation and potential market risks.

The US April Consumer Price Index (CPI) is forecasted to rise sharply to 3.9%, with core CPI also expected to increase by 0.4% month-over-month, up from 0.2% in March. This inflationary spike is driven by supply shocks, indicating an early phase of inflation pressures. Despite this, financial markets remain complacent, with the stock market heavily focused on AI investments, creating a bubble that could be vulnerable to a Federal Reserve hawkish stance. Investors should watch for potential market corrections as inflation data unfolds.
