On 15 March the price of an ounce of gold in U. S. dollars was $1501.25, today (4 June) it is $1710.50, a change of around + 14%.
On 15 March the price of an ounce of gold in Australian dollars was $2451.20, today it is $2460.25, a change of just 3/10ths of 1 %.
The difference between the two is simply the difference in the value of the currencies that gold is quoted in.
On 15 March the Australian dollar was worth $0.57 U.S. cents, today it is worth $0.69 U.S. cents, a difference of +21% (you can see this move on the far right end of the currency chart below).
This move has been fairly sudden and has brought us closer to the trend line, so gold prices in AUD should be expected to move in closer lockstep with gold priced in other currencies going forward.
It’s worth noting that despite the large rally in the AUD, gold has very recently reached all-time highs in many currencies, including the Australian dollar. Many analysts expect that once the all-time U.S. dollar price of $1917 per ounce is reached then the next leg of the gold bull market will begin.
