The Fed said the improvement in Americans' net wealth was helped by strength in home prices and the stock market.
Household net wealth -- assets minus liabilities -- has been slowly clawing back since it crashed by $12 trillion in 2008 after reaching $67 trillion a year before, BusinessWeek reported Thursday.
As households improved their financial positioning, the U.S. Treasury issued a net $1.2 trillion in debt, with the Federal Reserve and foreign investors as the main buyers.
Analysts said the household net worth growth was attributable to both an increase in assets and a decline in liabilities, BusinessWeek said.
Some growth in household debt could be considered a "positive sign for the economy" if it isn't too extreme, IHS Global Insight said in a commentary on the Fed report.
