The dollar sank 11.7% over the last twelve months, and gold climbed 10%.
The dollar is measured against a basket of non-redeemable paper currencies, the euro (57.6%), the yen (13.6%), pound sterling (11.9%), Canadian dollar (9.1%), Swedish krona (4.2%) and the Swiss franc (3.6%).
Only a few decades ago currencies were measured against gold. For people to see how well their domestic currency was doing, all they had to do was to look at the price of gold. That is still true today, but is not generally recognized by the public. When the dollar is in trouble, gold rises. When the dollar is strong, gold prices decline.
