i said best, not good. you may be right. i'd be interested in your thoughts as a better substitute, we're all gonna need the answer to this question soon.
I would argue that the difference between how countries are insulted is fairly small if it was a major, economically apocalyptic crash. Swap out your currency for items of value (spades, shoes, gay porn magazines) and run for the hills. More specifically find a country that has lots of fresh water, good renewable power sources, a low population (to avoid mass hysteria) and is fairly self reliant (imports not needed).
I imagine investing in precious metals, commodities (wheat etc), Isolated-country debt (Norway perhaps? Don't know tbh). In reality hedging is an extremely complicated process, especially against the dollar.
Hell, better start buying those credit default swaps if you're worried right?
A quote from the economist:
America's only known instance of outright default (other than refusing to repay debts in gold in 1933) occurred in 1979 when the Treasury failed to redeem $122m of Treasury bills on time. It blamed unprecedentedly high interest from small investors, a delay in raising the debt ceiling and a word-processing-equipment failure. Although it repaid the money and a penalty to boot, a later study by Terry Zivney, now of Ball State University, and Richard Marcus of the University of Wisconsin-Milwaukee found it caused a 60-basis-point interest-rate premium on some federal debt. Today that would cost $86 billion a year or 0.6% of GDP, a hefty penalty for something so avoidable.
No one really knows what will happen.
