Rogoff: Bubbles lurk in government debt

"...A prolonged explosion of government debt is, in turn, an exceedingly common characteristic of the aftermath of crises. As for the probable non-bubbles, most emerging markets face better prospects in the decade ahead than does the developed world, and their central banks will probably want to continue diversifying their reserve holdings. Of course, huge volatility and corrections along the way are normal...

Unfortunately, all too often the size of debts, especially government debts, is hidden from investors until it comes jumping out of the woodwork after a crisis.

In China today, the real problem is that no one seems to have very good data on how debt is distributed, much less an understanding of the web of implicit and explicit guarantees underlying it. But this is hardly a problem unique to China. Even as published official government debt soars, huge off-balance-sheet guarantees and borrowings remain hidden for political expedience around the world. The timing is very difficult to call, as always, but even as global markets continue to trend up, it is not so hard to guess where bubbles might be lurking..."
