The next global bubble is already under way. What happens when the most powerful nation in the world, with a reserve currency everyone trusts and holds, decides to push a big credit expansion — again, at the instigation of our financial sector? The creditworthy borrowers this time are not in the United States — they are in Asia, Latin America, and even Africa. They have little debt and great prospects; for a mere 1 percent per year they can borrow American dollars, spend the funds at home, and turn paper money into real assets. Every great bubble begins with a truly convincing shift in fundamentals.

In the 1990s this was called the “carry trade.” You borrowed from the Japanese at 1 percent and bought anything outside Japan that yielded a bit more (including United States subprime mortgages). The coming American carry trade is the same thing: it weakens the dollar, lifts the economy out of recession through exports, and creates inflation that reduces the real value of our debts. This can last quite a while — both the Treasury and the Fed are sure that early attempts to tighten policy prevented serious recoveries in Japan in the mid-1990s and in the United States toward the end of the 1930s.
