Minyak dan emas adalah dua komoditas penting dalam sejarah umat manusia. Walaupun emas memiliki sejarah lebih tua dibanding minyak (emas ditemukan sekitar tahun 2600 sm di Mesir sedangkan minyak pertama kali ditambang tahun 342 sm di Cina), namun keduanya memiliki peran penting baik dalam bidang energi dan moneter dan korelasi positif dalam statistik.
Gambar di samping adalah harga emas dan minyak sejak tahun 1946-2012. Dan trend linearnya adalah berapa barel minyak yang dapat dibeli dengan satu ounce emas dalam periode tersebut. Secara rata-rata (kurun 1946-2012) satu ounce emas dapat membeli 14,771 barel minyak. Bahkan harga emas dalam kaca mata minyak (gold/oil rate) adalah sama pada tahun 1947, 1974 dan 1999 pada saat peluncuran euro. Sehingga harga emas dan minyak hanya memiliki perbedaan yang kecil saja secara real term. Hal ini menunjukkan kestabilan emas dibanding komoditas energi dunia seperti minyak.
