The payoff in credit card debt that occurred during October, in the wake of 9/11 attacks, was short-lived as consumers have since returned to more normal credit patterns. During November, Americans piled on more than $5 billion in revolving credit, mostly credit card debt. Record low interest rates and holiday spending may have been responsible for the rebound. According to the monthly figures released by the Federal Reserve this week, Americans added $5.4 billion to revolving credit during November, following a $3.7 billion pay down in October. While the rebound reversed a trend that began in July, total revolving credit remains about $6 billion below the record level set in June of this year, when total revolving credit topped $700 billion. According to the Federal Reserve, revolving debt stood at $694.6 billion during November. At the end of November, American consumers were $1.653 trillion in debt, exclusive of home mortgages.
