Paul Krugman: A Crisis of Faith

A decade ago, during the last global financial crisis, the word on everyone’s lips was “contagion.” Troubles that began in a far-away country of which most people knew nothing (Thailand) eventually spread to much bigger countries with no obvious connection to Southeast Asia, like Russia and Brazil.

Today, we’re witnessing another kind of contagion, not so much across countries as across markets. Troubles that began a little over a year ago in an obscure corner of the financial system, BBB-minus subprime-mortgage-backed securities, have spread to corporate bonds, auto loans, credit cards and now — the latest casualty — student loans.
