More on Brad Setser

Further to the last, it's worth struggling through Brad Setser's presentation to the Congressional committee even if (like me) you're not an economics buff.
In essence, he says that America has gotten away with its continuing trade deficit over the last few years, for several reasons:
  • the effective interest rate on foreign debt held by the US, is higher than on loans made by foreigners to America

  • foreign equities have had higher yields and better capital appreciation, so US overseas investment has done better than foreigners' share holdings in America

  • the weakening dollar has amplified the effects in both points above

  • foreign central banks' willingness to buy US debt has kept US interest rates low, making Americans' debts easy to service and fuelling share and property booms

But it can't go on for ever. Either America's debts will continue to increase, or foreign sovereign wealth funds will buy more and more equities, or both. If foreigners slacken in their support for US debt, interest rates will rise; and losing equities to foreign owners takes away from America's future wealth and income.

Setser concludes:

The US will likely both have to sell more equity to the rest of the world and pay a somewhat higher interest rate on its external debt than it has recently...

While rapid central bank reserve growth and large official financing of the US deficit can help the US postpone the necessary adjustment, the longer the adjustment is deferred, the greater the long-term risks...

Bringing the US deficit and emerging economy surpluses down without tremendous costs will also take time. If the US and the world are to adjust gradually, they need to get started.

Yet again, I wonder whether the UK's enormous purchases of US dollar-denominated securities since June 2006 make sense for Britain.

Another thought: seeing two late market interventions last week, Dan Denning in The Daily Reckoning Australia (3 August) speculated that there may be "...in the financial market a buyer of last resort who comes in to goose the indexes at critical times, when investor confidence is especially fragile."

Rather than the Plunge Protection Team, could it be foreign sovereign wealth funds buying-in on the dips? Maybe that's why the Dow has bounced back 286 points today, as I write.
