The June CPI is a significant report before the Federal Reserve's interest rate meeting at the end of this month, which will guide the Fed's next rate hike action.
Currently, the market expects a probability of 92.4% for a rate hike by the Fed in July. The lower-than-expected CPI results may not be sufficient to change the decision of a 25 basis points rate hike in July, but it will help reduce expectations of further rate hikes by the Fed after July.

The decrease in expectations of two rate hikes would be beneficial for the S&P 500 index. JPMorgan predicts that if the CPI grows year-on-year between 3.05% and 3.2%, the S&P 500 index will rise by 1.5% to 1.75%. If the CPI grows year-on-year between 3.05% and 3.2%, the S&P 500 index will rise by 0.5% to 0.75%. Conversely, if the CPI grows year-on-year between 3.3% and 3.6%, the S&P 500 index will fall by 1% to 1.25%.
We believe that the CPI data this time will meet expectations, and the S&P 500 index is expected to modestly rise by 0-1%.
