Copper fell for a second day in New York and London before a report that may show cooling house prices in the U.S., the world’s second-largest user of the metal.
Property values in 20 cities increased 3.1 percent in July from a year earlier, below the 4.2 percent gain in the 12 months to June, according to the median forecast of 28 economists surveyed by Bloomberg News. Separate figures may show consumer confidence in the U.S. weakened.
“Good U.S. consumer-confidence and house-price data are crucial for metals and other risk assets to avoid further losses today,” said David Thurtell, a Citigroup Inc. analyst in London.
Copper for delivery in December dropped 1.8 cents, or 0.5 percent, to $3.579 a pound at 8 a.m. on the Comex in New York. Copper for delivery in three months slid 0.6 percent to $7,861 a metric ton at on the London Metal Exchange. All of the six main metals traded on the LME retreated except tin.
The S&P/Case-Shiller home-price figures are scheduled for release at 9 a.m. in Washington. Construction accounts for a quarter of copper demand, according to the Copper Development Association.
