To say that “a higher gold price is not correlated to money supply growth” is fundamentally correct. However, the expectation for a much higher gold price resulting from huge money creation by the Federal Reserve is shared universally by investors, analysts, and others.
In fact, it is considered almost scriptural canon that a huge increase in the money supply will lead inevitably to a huge increase in the gold price. Historical examples of France in the late 18th century, Germany (Weimar Republic) in the 1920s, and Zimbabwe or Venezuela more recently, are often cited as proof of the relationship between money supply growth and its effect on gold prices.
That is not the case, though.
