U.S. Stocks Rebound on Proposed U.S.-Iran Diplomatic Talks

U.S. stock indexes rebounded on October 20, 2026, following reports that mediators presented a proposal to revive diplomatic talks between the United States and Iran. The Dow Jones Industrial Average led the recovery, rising 1% or 530 points, while the S&P 500 increased by 0.3% and the Nasdaq remained flat.

The gains followed an initial morning dip and a broader downturn in Asian markets. That volatility was triggered by a South Korean data-center company whose shares fell 32% during its market debut.

Energy markets reacted to the diplomatic news with a decline in oil prices. Brent crude futures fell 0.7% to $108.79 a barrel, and U.S. benchmark crude futures dropped 1.8% to $101.79 a barrel.
