Oil prices fell today closing out a volatile week little changed. On Thursday, data from China showed its economy lost momentum in July, with new home prices falling at the fastest pace in nine years, industrial output slowing and unemployment rising. That has stoked worries among traders about a slump in demand from the top oil importer, where refineries sharply cut crude processing rates last month on tepid fuel demand. “It has been a volatile week in oil markets: on one hand you had fears of supply disruptions from a wider Middle East war, but on the other, slowing growth in China forced revisions of demand forecasts,” said Andrew Lipow, president of energy consultancy Lipow Oil Associates. WTI traded down $1.51 or -1.9% to close at $76.65. Brent traded down $1.36 or -1.7% to close at $79.68.
