What we see here is a flight of consumer to safety from the currency to gold. One further step that we recommend would be flight of gold from that jurisdiction. Today, turmoil throughout much of the world is causing high net worth citizens to look to gold as insurance against the degrading of currency and ability of a country to tax its citizens. Many people inherently know the risk of picking a currency. They understand price differences when they cross the border from Canada to the US to shop but this is one step more. This is going straight to the fundamentals or ground floor. We have not used the gold standard for quite some time; yet, gold still plays a crucial role to central and investment banks while simultaneously these players tell the people to ignore it. We have historically derived value from gold. Most of the world understands this, but in the West we have been removed from that discussion. We play the paper money game. Is that game in danger? Are people commenting on it? Not in the mainstream news, but most definitely yes. It is being noticed outside those media public relations outlets.
This is important when we see that Turkey has given its central bank first right of refusal on all domestically produced gold. This is another example, like China, of a country bolstering its gold hoarding while citizens lag behind. Something curious to consider.
