Bond buyers trust Buffett more than Uncle Sam

For many decades, U.S. government securities have been the epitome of safe, dull investments. If you wanted to be absolutely positive you'd get your money back and then some, Treasury bills were the way to go. Right now, lots of Americans who put their money into big mortgages or stocks a decade ago wish they had gone the more mundane route.

But it's mundane no more. With federal budget deficits running wild, investors are growing uneasy at the idea of lending money to an institution that seems unable to stop spending beyond its means. Last month, something extraordinary happened: Two-year bonds offered by Berkshire Hathaway Inc. commanded lower yields than those offered by the U.S. government. As Bloomberg.com put it, "The bond market is saying that it's safer to lend to Warren Buffett than Barack Obama."

That may sound common-sensical — Buffett has experience at meeting payrolls, while Obama does not — but it's actually a surprising perception. Berkshire Hathaway, after all, conceivably could make so many mistakes that it runs out of money and closes down. But the U.S. government is not about to run out of money, even if it keeps overspending.

Why not? First, it can appropriate more of its citizens' earnings through the tax system. Second, and more important, it can print money to pay its bills. Warren Buffett doesn't have those options.

So it's hard to see why investors would be leery. Well, actually, it's not so hard: The federal government is digging itself deeper into debt every month and intends to keep doing so indefinitely.
