As fears of England leaving the European Union came to a head on voting day, a stunning scene emerged on the streets of London. Though it was completely ignored by the mainstream media, the fact that Brits were lining up in droves in front of gold and silver shops spoke volumes about financial assets of last resort during a real or perceived crisis.

It is within this context that legendary resource investor Doug Casey warns that the hurricane which took the world by storm in 2008 is still a significant threat. While we've spent the last several years in relative peace and calm inside the eye of the storm, we'll be entering the other side of the hurricane wall later this year, says Casey. And as we've seen in London, Greece, and Argentina in the past decade, when financial hurricanes wreak havoc across the economic landscape, the only safe haven to be had is in precious metals:

We're at the start of a really major bull market… This is going to be driven by a lot of things… It's going to take gold a lot higher than most people can imagine at this point.

…

… I think $5,000 gold will happen at some point because we're looking at a worldwide monetary crisis of historic proportions.
