What $100 in 1991 was worth — measured in gold

The price of gold didn't get more expensive. The value of the Australian dollar fell.

91.9%

of the Australian dollar's value, gone — measured in gold, since 1991.
It now takes 12.4× more dollars to buy the same ounce.

In 1991, $100 bought 0.22 oz of gold at $465/oz. Held as metal, that same money is worth $1,240 at today's gold price of $5,761/oz (spot as of 2026-08-02).

Same $100. Three rulers.

Measure	$100 from 1991, today	Multiple
Official story — AU CPI (ABS via FRED)	$237	2.4×
Money created — M3 broad money	$1,263	12.6×
In gold — honest weight, valued today	$1,240	12.4×

The gap between 2.4× (CPI) and 12.6× (M3) is official inflation understating the money actually created. The gap between 12.6× and 12.4× (gold) is the flight to hard money — gold outrunning even the printing.

1991 in the fiat story

"The recession we had to have" opened the decade; inflation targeting arrived in 1993. Gold spent the nineties in a global bear market, which made the Australian dollar look sounder than it was.
