Wall Street stocks fell Tuesday as oil prices kept climbing and raised concerns about high inflation.

The S&P 500 dropped 0.4%, the Dow fell 190 points, and the Nasdaq slipped 0.5%.

The weak start to September followed a mostly positive August for major indexes.

Technology stocks weighed heavily on the market.

Microsoft fell 1.3% and Advanced Micro Devices dropped 2.4%.

Their large market values give them strong influence, and their growth has relied on borrowing, which gets costlier as interest rates rise.

Pressure also came from a sell-off in U.S. government bonds.

The 10-year Treasury yield rose to 4.77% from 4.75% late Monday.

The 2-year yield climbed to 4.37% from 4.34%.

Rising yields signal that investors see Treasurys as riskier, partly due to growing government debt, which surpassed $40 trillion two weeks ago.

Oil prices drove much of the inflation pressure.

Brent crude rose 2.3% to $92.61, with the Strait of Hormuz effectively shut down amid the U.S. war with Iran.

Higher energy costs have pushed up prices for gasoline and shipped goods.

Inflation remains above 3%, and investors see a 66% chance the Fed will raise rates at its September meeting.

European markets fell, while Asian markets were mixed.
