After declining throughout much of 2009, American consumer confidence improved sharply this month, returning to levels not seen since the financial crisis began in September 2008, according to the most recent results of the RBC CASH (Consumer Attitudes and Spending by Household) Index. Driven by the largest-single-month gain in expectations for jobs since the inception of the Index eight years ago, the RBC Index for January 2010 stands at 58.3, up 19.3 points from its December 2009 reading of 39.0.
