Inflation remains tame: U.S. consumer prices unchanged in July

More good news amid a week of positives for U.S. investors: inflation remains tame. Consumer prices were unchanged in July, the U.S. Labor Department announced Friday, as a lack of demand led to little pricing power in the U.S. economy.

What's more, the U.S. economy over the past year shows little sign of inflation: consumer prices have actually declined 2.1 percent in the past 12 months -- the biggest yearly decline in prices since 1950.
