History

Historical Context

July 2026 chip-maker losses echo the 2008 crisis, when Lehman’s collapse sent the Dow down 733 points and led the Federal Reserve to cut rates by 0.5 percentage point. Then, equity swings persisted despite steady rates, a pattern resurfacing as Intel and Seagate tumble while investors watch UnitedHealth earnings and Iran-Houthi oil-route tensions.
