March 19 (Reuters) - Wall Street's main indexes opened

lower on Thursday as crude prices soared on intensifying Middle

East hostilities, reviving inflation worries that have prompted

the Federal Reserve to take a more cautious stance on interest

rate cuts.

The rate-sensitive small-caps Russell 2000 index

dropped 10% from its all-time intraday high.

The Dow Jones Industrial Average fell 90.3 points, or

0.20%, at the open to 46,134.87. The S&P 500 fell 41.6

points, or 0.63%, at the open to 6,583.12​, while the Nasdaq

Composite dropped 281.4 points, or 1.27%, to 21,871.037

at the opening bell.
