Last week CNN Money revealed that according to Berkshire Hathaway's latest filing, Buffett had raised his bet against dollar to $19 billion.
Back in last November, Fortune had a famous exclusive interview with Warren Buffett. The tone from the Oracle was he found so few opportunities in the domestic market that he'd rather sit on piles of cash, and he believed America's growing deficit is going to hurt us sometime. The recent disclosure again demostrated Buffett is unchanged in his opinion and he is putting more of his money where his mouth is.
Between dollar and Buffett, I'd rather bet on Buffett. But what can an individual do? Maybe you can park some of your savings in foreign currencies. For example, EverBank offers some accessible foreign currency products. You may also want to hedge your US dollar-denomiated wealth by purchase foreign exchange (forex) futures or options, but it may be costly or inefficient for small amount.
I have to confess I don't have a good answer. The only hedge I have is about $4,000 investment in international equity funds in my 401(k) account, but it is less than 3% of my net worth and if dollar tanks, it is not going to help me much.
Maybe, a better option is to buy the shares of Berkshire Hathaway :-)
