"Creating tons of new money and credit out of thin air is not without cost."

"Central bankers contributed to the economic crisis the world now faces. They kept interest rates too low for too long. They fixated on controlling inflation, even as they stood by and watched investment banks party in an orgy of credit. Central bankers were completely incompetent and failed to see the Great Financial Crisis coming. They couldn't spot housing bubbles, and even when the crisis had started and banks were failing, they insisted that the banks they supervised were well regulated and healthy. They failed at their job and should have been fired. Yet governments now need central banks to erode the mountain of debt by printing money and creating inflation.

...if central bankers couldn't manage conventional monetary policy well in the good times, what makes us think that they will be able to manage unconventional monetary policies in the bad times?

...Economists know that there are no free lunches. Creating tons of new money and credit out of thin air is not without cost. Massively increasing the size of a central bank's balance sheet is risky and stores up extremely difficult problems for the future.
...the experiment is unlikely to end well.

...Central banks think they can swell the size of their balance sheet, print money to finance government deficits, and keep rates at zero with no consequences. Bernanke and other bankers think they have the foresight to reverse their unconventional policies at the right time. They've been wrong in the past, and they will get the timing wrong in the future. They will keep interest rates too low for too long and cause inflation and bubbles... What they are doing will destroy savers who rely on interest payments and fixed coupons from their bonds. They will also harm lenders who have lent money and will never be repaid in devalued dollars, if they are repaid at all.

We are already seeing the unintended consequences of this Great Monetary Experiment. ...Investors are reaching for riskier and riskier investments to get some small return. ...Older people who are relying on pension funds to pay for their retirement are getting screwed...

When investors convince themselves central bankers have their backs, they feel encouraged to bid up prices for everything, accepting more risk with less return. Excesses and bubbles are not a mere side effect. As crazy as it seems, reckless investor behavior is, in fact, the planned objective. William McChesney Martin, one of the great heads of the Federal Reserve, said the job of a central banker was to take away the punch bowl before the party gets started. Now, central bankers are spiking the punch bowl with triple sec and absinthe and egging on the revelers to jump in the pool..."
