(Fortune) — Total household debt fell by $77 billion during the three months ending in June, but nearly half of that decline stemmed from bank charge-offs of residential mortgages, credit cards and other consumer loans, according to Capital Economics Group. In a recent report, the London-based economic research consultancy found that this isn’t necessarily a new development. Household debt has fallen every quarter since the beginning of 2008, leaving it $473 billion below the peak, which is the equivalent of reducing debt at every household by $4,200.
Shedding away debt – however it’s done – is critical to the overall health of the economy. But the wave of households de-leveraging by default is worrisome. And many Americans are using their new savings to buy up U.S. Treasuries instead of devoting it all toward paying down debt. During the past year, households bought 42% of the new Treasury debt issued, equal to about $616 billion and far more than the $432 billion absorbed by foreign investors.
