Paul Kedrosky has posted an informative chart from JPM's Michael Cembalest indicating that ownership of gold in dilutable terms (aka dollars), as a portion of global financial assets has declined from17% in 1982 to just 4% in 2009. And even thought the price of gold has double in the time period, as has the amount of investible gold, the massive expansion in all other dollar-denominated assets has drowned out the true worth of gold. Were gold to have kept a constant proportion-to-financial asset ratio over the years, the price of gold would have to be well over $5,000/ounce.
Of course, the chart above pales in comparison with the true Exter pyramid, which incorporates all those wonderful JPM/Goldman inventions known as derivatives, amounting to $1.8 quadrillion, which certainly did not exist in 1982. If one were to factor the above table to include this Exter securitized credit money as well, then the true constant worth of gold would be well north of $10,000.
