Remarks on the role of the exchange rate and structural policies in correcting current account imbalances

Mr. Rintaro Tamaki, Deputy Secretary-General, OECD

SEMINAR ON EXCHANGE RATES AND TRADE27-28 March 2012

1

Impact of exchange rates on trade

There is no consensus on:

• Methodology to measure exchange rate alignment

• Impact of exchange volatility on trade

• Magnitude of the impact of exchange rates on trade flows.

2

Impact of exchange rates on trade is unclear due to:

• Potentially high import content of exports in globally integrated economies

• Price elasticities of demand differ across products

• Different price transmission mechanisms according to product and market

• Hedging and other risk management practices differ by size of firm.

3

Global imbalances widened prior to the crisis (Sum of absolute current accounts in US$, as % of area-GDP)

Reforms that are desirable on welfare, equity or efficiency grounds may also reduce global imbalances

• Developing social welfare systems in China and other Asian economies would reduce precautionary saving, so moderating current account imbalances in surplus countries.

• Removing competition-unfriendly product market regulation could encourage capital spending in countries like Japan and Germany.

• Financial market reforms may relax borrowing constraints in emerging economies and thus help to reduce the high saving rates.

• Removing policy distortions that encourage consumption such as tax deduction of interest payments on mortgages might increase household saving in some countries including the United States.

+ More ambitious fiscal consolidation would reduce imbalances because government indebtedness is typically higher in deficit countries.5

A scenario analysis shows that fiscal consolidation combined with structural reforms can substantially

reduce global imbalancesAbsolute sum of global current account balances as % of world GDP

Note: The size of imbalances is measured as the sum of the absolute current balance-to-GDP ratios, weighted by

2009 GDP (in current USD). The starting values are based on the current-account-to-GDP ratios in 2009 .
