GLOBAL IMBALANCES: 1990-2009
CURRENT ACCOUNT DEFICITS AS A % OF WORLD GDP

U.S. MONETARY POLICY, 1999-2009

TAYLOR RULE (FROM BERNANKE,
2010)

5

REASONS TO BE CIRCUMSPECT



“Reasonable” Disagreements about:



Ingredients (measure of inflation, output gap)
Coefficients (on output gap, inflation…)



Prescriptive content of the rule is not obvious



Throughout the period, inflation remained stable and
well-anchored, while output was also growing.

LOW REAL INTEREST RATES, 2000-2009

DEALING WITH ASSET BUBBLES: SHOULD THE
FED LEAN?


The Fed’s view:
1.
2.
3.
4.
5.






Markets take care of themselves
Undesirable for price stability
Difficult to identify bubbles
Effectiveness of raising rates on bubble is unclear
Interest rate policy can “mop-up”

(1) and (5) casualties of the crisis
But (2)-(4) remain. Interest rate policy may not be the
instrument of choice.
Bigger failure : Fed failed to remain vigilant.

WHAT GLOBAL FACTORS?


Global Imbalances? Unlikely





Instead, post 2001 and 2004: massive surge in
demand for U.S. “triple-A” debt instruments




What matters is global savings and global investment.
Could have “rebalanced” without changing the cost of
funds

Asymmetry between economic and financial
development in emerging economies
Post 2001, rebalancing of portfolios
Surge in reserve accumulation from EM to insure
against sudden stop
Sterilization policies from surplus countries to peg their
currency in dollar terms.

Why U.S.? Historical liquidity provider.

U.S. AS GLOBAL LIQUIDITY PROVIDER
DEBT AS % OF GROSS LIABILITIES; EQUITIES AND FDI AS % OF GROSS ASSETS

11

SAFE-ASSET IMBALANCE


Global surge in demand for safe U.S. assets







Profit opportunity for U.S. financial sector: manufacture
quasi triple-A debt assets from riskier assets
(securitization)
Transfer demand for safe assets to other classes and
fuels housing bubble. Wealth increases allows more
borrowing. Feedback loop.
Synthetic assets much more vulnerable to systemic risk
When financial crisis occurs, run on structured credit
instrument. Only bona-fide safe assets are U.S.
Treasuries.

CONCLUSION
Monetary policy in 2001-2007 no immediate threat
to the economy
 Interest rate policy is a second or third best
instrument.
 But low real interest rates, strong growth and
housing bubble should have pushed policymakers
to be more vigilant and more creative


Global imbalances played limited direct role
 More important was the demand for safe U.S. debt
instrument.
