U.S. oil futures end higher on Russia-Ukraine conflict, but well below the day's highs above $100

U.S. oil futures topped $100 a barrel on Thursday after Russia’s full-scale invasion of Ukraine. Prices, however, finished with a more modest gain. Oil and natural-gas supplies are still unaffected by the current escalation, but “there is a concern that at some point they may get cut off,” said Michael Hewson, chief market analyst at CMC Markets UK. West Texas Intermediate crude for April delivery CLJ22, +1.14% rose 71 cents, or 0.8%, to settle at $92.81 a barrel on the New York Mercantile Exchange after trading as high as $100.54.
