US Stocks Fall as Borrowing Costs Hit 5%

U.S. stocks kept falling September 15, 2026, per MarketWatch, with the Dow — 30 big U.S. companies — down 500 points. Washington’s 10-year borrowing rate hit 5%, per MarketWatch. Like higher mortgage rates, that raises costs for borrowers and pressures stocks. I see money getting tighter as the Fed opened its September 15-16 meeting.
