US stocks fall as September inflation tops forecasts, Treasury yields climb

US stock futures fell Wednesday after September inflation came in at 3.7% annually, above the 3.6% expected, raising concerns about persistent price pressures and prompting Treasury yields to rise. Core CPI, excluding food and energy, rose 0.3% monthly and 2.6% annually, both slightly above forecasts. The 10-year Treasury yield climbed over 6 basis points to 5.278%, adding pressure on stocks as bonds become more attractive. Bank of America shares dropped about 3% after missing earnings estimates and facing over $1.2 billion in penalties. Chip stocks extended losses, while oil prices rose nearly 2% to around $96 per barrel, with gasoline averaging $4.34 per gallon.
