DOLLARS AND DEFICITS – THE US CURRENT ACCOUNT DEFICIT AND ITS EXCHANGE RATE CONSEQUENCES

The path of the dollar In the past three years the US dollar has been declining whilst the US current account deficit has expanded, and these two developments are clearly linked. However, the causes of the decline in the dollar and the solution to the US deficit may not be as closely related as at first may appear. The emergence of a sustained deficit does not automatically necessitate a fall in the exchange rate, and a fall in the exchange rate may not correct such a deficit. Deficits can exist if the currency moves above its sustainable real exchange rate, and a real depreciation can remove such a deficit. Deficits caused by exchange rate movements are likely to be more temporary than those that either emerge for long-term structural reasons or result from structural imbalances in the economy.
