La crisis en créditos contagia a otros instrumentos "seguros"

Ahora, créditos sobre propiedades comerciales y aún los préstamos para colegiaturas universitarias están en problema.

Wall Street banks are bracing for another wave of multibillion-dollar losses as the crisis that began with subprime mortgages spreads through the credit markets.

In recent weeks one part of the debt market after another has buckled. High-risk loans used to finance corporate buyouts have plummeted in value. Securities backed by commercial real estate mortgages and student loans have fallen sharply. Even auction-rate securities, arcane investments usually considered as safe as cash, have stumbled.

The breadth and scale of the declines mean more pain for major banks, which have already written off more than $120 billion of losses stemming from bad mortgage-related investments.
