The Fetish for Liquidity (and Reform of the Financial System)

So here’s the deal. What happened is that the financial sector taken as a whole moved into extremely short-term finance of positions in assets. This is a huge topic and is related to the transformation of investment banking partnerships that had a long-term interest in the well-being of their clients to publicly-held, pump-and-dump enterprises whose only interest was the well-being of top management.

It also is related to the rise of shadow banks that appeared to offer deposit-like liabilities but without the protection of FDIC. And it is related to the Greenspan “put” and the Bernanke “great moderation” that appeared to guarantee that all financial practices—no matter how crazily risky—would be backstopped by Uncle Sam. And it is related to very low overnight interest rate targets by the Fed (through to 2004) that made short-term finance extremely cheap relative to longer-term finance. All of this encouraged financial institutions to rely on insanely short short-term finance

The Volatility Paradox

Volatility tends to drop when market risk is building up and leverage is rising, luring investors into complacency. Indeed, the lower volatility justifies investors taking on more leverage; if volatility has dropped by a third, why not take one and a half times the leverage? This pro-cyclical dynamic arising from lower volatility in times of increasing risk-taking is the volatility paradox. The main take-away from the volatility paradox is that we shouldn’t use shorter-term, contemporary risk measures when they are very low
