U.S. inflation data preview: September CPI and what it means for markets
Market context: SPY: CPI prints drive broad equity index expectations for rate cuts or hikes. A hotter CPI would likely pressure equities, while a cooler print could support them. TLT: Inflation data directly shapes Treasury yield expectations and long-duration bond prices. Higher-than-expected CPI would likely push yields up and weigh on long-duration Treasuries. DXY: Inflation differentials and Fed policy expectations influence the dollar. A hot CPI would likely strengthen the dollar on reduced cut expectations, while a soft print would weaken it.
