Corridas Bancárias do Séc. XXI

Corridas bancárias do séc. XXI são diferentes, como explica Tyler Cowen:

"The new complication is that bank deposits are no longer the dominant form of modern short-term finance. The modern bank run means a rush to withdraw from money market funds, the disappearance of reliable collateral for overnight loans between banks or the sudden pulling of short-term credit to a troubled financial institution. But these new versions are in some ways still similar to the old: both reflect the desire to pull money out of an endeavor — and to be the first out the door. And both can set off a crash.
These newer forms occur in the so-called shadow banking system, involving short-term financial credit not guaranteed by the deposit insurance umbrella. According to the Federal Reserve Bank of New York, shadow banking accounts for about $15 trillion in assets — more than the traditional banking system. But as recently as 1990, the shadow-banking total was much lower, at less than $4 trillion. The core problem is that the growth of short-term credit has been outracing our ability to protect it, and since 2008 most investors have realized that these shadow-banking transactions are not risk-free"
