Geopolitical escalation and a softer dollar are driving today's tape

Friday, August 21, 2026. From GEO's evening brief, after the close.

Trump's "economic D-Day" package against Iran lifted Brent to $93.87/bbl, while a dollar index at 98.84 fueled a broad metals rally, with platinum leading at $1,891.40, up 2.84%, and gold up 1.97% to $4,661.60/oz. In grains, corn led higher at 508.25¢/bu after Pro Farmer's crop-tour estimates.
