WASHINGTON (Reuters) - US oil prices tumbled for a second day on Tuesday as market concerns over limited progress in Sino-US trade talks on scrapping trade duties.
US West Texas Intermediate (WTI) crude fell 27 cents, or 0.47 percent, to $ 56.78 a barrel, further away from Friday's eight-week high when hopes of a trade deal grew.
Brent crude futures were down 20 cents, or 0.32 percent, at $ 62.24.
