Walmart's sales shortfall and rising government borrowing costs signal trouble ahead

On August 20, 2026, major stock indexes fell: the Dow 0.86%, S&P 500 0.44%, and Nasdaq 0.92%. The interest rate the U.S. pays on 30-year loans rose to 5.244%. Walmart fell 8.6% after reporting weaker-than-expected sales. When borrowing gets pricier and shoppers pull back, the economy can stall while prices keep climbing — a painful mix worth watching.
