Yes, and it does make you wonder also about what Iraq, Syria, Ukraine and Libya have in common that is worth something (that people would fight over), and out pops oil and/or gas.

On a parallel theme you have the dominance of the USD as the global currency of choice.
The dollar has been the preeminent global reserve currency for most of the past century. Also it is "the" petrodollar. Its status as the dominant world currency was cemented by the perception of international investors, including foreign central banks, that U.S. financial markets are a safe haven.

Safety implies a lot of things, but there is a strong binding element of trust, and belief in strong regulations, robust regulators, governance, transparency (etc), that back the global currency.

My trust based on the events of the last 15 years, is simply shattered. As some one mentioned, or wrote about " In Gold we Trust". Interesting web sites below,
