What is an auction buying agent?
It’s where you use a third party to purchase something and then you purchase it from them.
As long as the Fed is paying a premium price on the secondary market, there is no need to purchase at the primary auction.
Bill Clinton used to use the Currency Stabilization Fund to sell gold futures in order to suppress the price of gold. He almost got burned until Tony Blair bailed him out by announcing a large sale of gold that put the price below the futures exercise price. Blair never sold the gold.
Then Bill Clinton changed the computation of the Cost of Living Index to allow substitutions. Inflation figures have been manipulated ever since.
