The Treasury plan is a disgrace: a bailout of reckless bankers, lenders and investors that provides little direct debt relief to borrowers and financially stressed households and that will come at a very high cost to the US taxpayer. And the plan does nothing to resolve the severe stress in money markets and interbank markets that are now close to a systemic meltdown.

The global financial crisis - missed by most analysts - shows that most forecasters are poor at pricing in economic/financial risks, let alone geopolitical ones.

In an extreme credit crunch, leveraged purchases of gold cause forced sales, because any price correction triggers margin calls. As a result, gold can be very volatile - upward and downward - at the peak of a crisis.

A currency serves three functions: providing a means of payment, a unit of account and a store of value. Gold may be a store of value for wealth, but it is not a means of payment. You cannot pay for your groceries with it. Nor is it a unit of account. Prices of goods and services, and of financial assets, are not denominated in gold terms.

We're essentially continuing a system where profits are privatized and...losses socialized.
