Sept. 24 (Bloomberg) -- Emerging-market stocks retreated to a one-week low as a decline in commodities sank producers from Petroleo Brasileiro SA to OAO Mechel. Indonesia’s rupiah weakened to the lowest level since November 2009.
The MSCI Emerging Markets Index fell 0.6 percent to 1,010.56, the lowest since Sept. 18. Brazil’s Petrobras paced losses in energy shares, while Mechel, Russia’s biggest producer of coal for steelmakers, sank 2 percent. China’s stocks slid, led by the biggest drop in financial companies in two months, on concern the government may encourage more competition among banks and expand property taxes. The rupiah slipped on speculation local companies boosted dollar purchases.
Commodity companies posted the biggest declines among 10 industries in the measure for developing-nation stocks. West Texas Intermediate crude tumbled to the lowest level in eight weeks on speculation that U.S.-Iranian relations are thawing and as the threat of an American military strike on Syria recedes. Gold, copper and silver also retreated.
“It’s a cliche, but it’s true: the market hates uncertainty,” Lawrence Creatura, a Rochester, New York-based fund manager at Federated Investors Inc., which oversees about $364 billion, said by phone. “Resolution of the Syrian uncertainty, via political discourse or military action would likely be positive for the markets.”

Investors also watched U.S. economic data for clues on whether the Federal Reserve will trim its bond-buying program.
