Why it may matterVerify against the original reporting

Hot inflation data and rising deficits suggest higher-for-longer rates, which historically compress equity multiples and lift debt service costs. JPM misses add to financials downside risk; combined with policy uncertainty, this tends to weigh near-term S&P 500 levels, as seen in prior cycles when inflation surprised and rates stayed elevated.
