FreedomUIC: the Wiki definition of QE is below. QE2 is the second try at this. Many investors think this kind of "hail mary" scheme will cause the metal market to soar.
Wiki says:
The term quantitative easing (QE) describes a monetary policy used by central banks to increase the supply of money by increasing the excess reserves of the banking system. This policy is usually invoked when the normal methods to control the money supply have failed, i.e the bank interest rate, discount rate and/or interbank interest rate are either at, or close to, zero.
A central bank implements QE by first crediting its own account with money it has created ex nihilo ("out of nothing").[1] It then purchases financial assets, including government bonds, mortgage-backed securities and corporate bonds, from banks and other financial institutions in a process referred to as open market operations. The purchases, by way of account deposits, give banks the excess reserves required for them to create new money, and thus a hopeful stimulation of the economy, by the process of deposit multiplication from increased lending in the fractional reserve banking system.
Risks include the policy being more effective than intended, spurring hyperinflation, or the risk of not being effective enough, if banks opt simply to pocket the additional cash in order to increase their capital reserves in a climate of increasing defaults in their present loan portfolio
