  1. Global imbalances – where are they and do they matter? William R White Head of the Monetary and Economic Department Bank for International Settlements, Basel Slides prepared for the Chatham House Conference on Global Financial Imbalances New York, 24 April 2006 1

  2. Four sections • Everything is interrelated • The facts • What are people worried about? • Should they be worried?

  3. Everything is interrelated • (S-I) = (X-M) = CF = (M*-X*) = (I*-S*) • External imbalances reflect internal imbalances • Should they be worried?

  4. The facts • the US trade deficit is huge • the trade counterparties are diverse • the US also borrows to lend • the sources of finance are diverse but changing

  5. What are people worried about? • a smooth adjustment is possible, but not inevitable • problems of factor adjustment • protectionism • impatience in financial markets

  6. Should they be worried? • a current account perspective • a currency share perspective • a financial problem needing a real solution

  7. No problem from a current account perspective? • three reasons why strong US productivity growth helps • the “savings glut” hypothesis • the valuation bonus for the US • dark matter

  8. But counterarguments are convincing • troubling facts and the productivity argument • foreign dissaving with the US at full employment • the valuation loss for foreigners • even less than meets the eye

  9. No problem from a currency share perspective? • private sector holdings of dollar liabilities • public sector holdings of dollar liabilities • former much larger, but influenced by the latter

  10. Private sector holdings not a problem? • no dollar overhang • home bias is big but declining • moderate increases in rates provide adequate support for dollar

  11. But counterarguments are convincing • moderate covering could have big effects • declining home bias cuts two ways • low domestic rates support spending and imports

  12. Public sector holdings not a problem? • no dollar overhang (ex Japan) • the Bretton Woods II hypothesis • the world needs the liquidity

  13. But counterarguments are convincing • the dollar “bloc” is getting smaller • vendor financing is convenient, not sustainable • more global liquidity creates more problems than its cures

  14. Conclusions • do global imbalances matter? • arguments both ways, BUT • mean-reversion is more common than not
