Dow, Nasdaq Open Slightly Lower as Treasury Yields and Oil Prices Inch Higher

U.S. equities were slightly lower on Wednesday as Treasury yields and oil prices inched higher amid fresh uncertainty around the war between the U.S. and Iran.

The S&P 500 dropped 0.11%, while the Nasdaq Composite dipped 0.26%. The Dow Jones Industrial Average was down 53.6 points, or 0.1%.

Treasury yields increased, weighing on equity. The yield on the 10-year Treasury note climbed more than 2 basis points to 4.99%, as did the 30-year Treasury bond yield to 5.323%.

Futures tied to the major averages had reversed course from earlier gains after Brent crude oil futures moved up as well. Brent futures for November delivery were last seen trading 1% higher at around $100 a barrel, while U.S. West Texas Intermediate futures were up marginally at around $90 per barrel.
