Why the Treasury still prices gold at 42 dollars an ounce (Ad)

The U.S. Treasury still values its gold reserves at 42.22 dollars an ounce, a price set in 1973. Gold trades near 4,500 dollars today, a 113-to-1 gap between book value and market reality. Treasury Secretary Scott Bessent has said he wants to monetize the asset side of the balance sheet. A revaluation could add more than 1 trillion dollars to the government's books overnight. Certain gold miners still trade as if gold were under 2,000 dollars, even as prices near record highs.tc pixel
