Total household debt balances continued their upward climb in the first quarter of 2022 with an increase of $266 billion; this rise was primarily driven by a $250 billion increase in mortgage balances, according to the latest Quarterly Report on Household Debt and Creditfrom the New York Fed’s Center for Microeconomic Data. Mortgages, historically the largest form of household debt, now comprise 71 percent of outstanding household debt balances, up from 69 percent in the fourth quarter of 2019. Driving the increase in mortgage balances has been a high volume of new mortgage originations, which we define as mortgages that newly appear on credit reports and includes both purchase and refinance mortgages. There has been $8.4 trillion in new mortgage debt originated in the last two years, as a steady upward climb in purchase mortgages was accompanied by an historically large boom in mortgage refinances. Here, we take a close look at these refinances, and how they compare to recent purchase mortgages, using our Consumer Credit Panel, which is based on anonymized credit reports from Equifax.
