The Federal Reserve Bank is unlike any other bank or corporation. It literally can buy anything it wants for fraction of pennies on the dollar.
Say you are the Federal Reserve and you want to buy 10 ounces of newly mined gold. Assuming the market rate of $1,000 per ounce do you offer the mining company $1,000 for each an ounce? No, you offer to pay a 10 percent more because you really want some gold. So, you call the U.S. Treasury Department which prints up 11 one hundred dollar notes for each ounce you plan to buy for a total of 110 notes dominated as $100. You, of course, are kind enough to pay the Treasury Department for the cost of printing the 110 notes dominated as $100. Last time I heard the payment was four cents per note printed. So multiplying 110 by 4 cents comes to $4.40. So the Treasury delivers to you, the Federal Reserve, 110 one hundred dollar bill notes with a street value of $11,000 (which cost you only $4.40) and you turn around and give the $11,000 to the mining company and they cheerfully deliver to you 10 ounces of gold.
And you now say you want to give up being Mr. Central Banker. Why?
