I'm just your average middle class 9-5 working guy, so putting up millions in margin accounts may not be feasible... I have this theory that as long as stable governments can print money, they will not default on their bonds. This probably sounds beyond ridiculous but.I want to take advantage of this by selling CDS on sovereign debt. I'm willing to put up all my savings, 401K etc to pursue this. Is this even possible? If so, how can I go about figuring out how (if any) margining would work? Ideally, I'd want to do this OTC, with no daily mark to market/model. Of course, I'm confident that the sovereigns I'd be betting on would not default in my lifetime and I hope to make a very comfortable living from the premiums... This is a serious post, so please be nice.
