Under this, the long-term equilibrium exchange rate is that which generates both internal and external balance, where internal balance is defined as full employment and external balance as the current account. Since the creation of this model, the emphasis has shifted away from focusing on full employment to concentrating on achieving a sustainable current account balance — not necessarily zero — which will achieve a perceived economic and exchange rate equilibrium.
As with the Balance of Payments Approach, the current account is seen as the transmission mechanism for the exchange rate, albeit this time under both fixed and floating exchange rate regimes. If the current account balance is showing an unsustainably high deficit relative to historic deficit levels, this will require a real exchange rate depreciation to restore equilibrium. Conversely, if it is showing a very high current account surplus, this will require a real exchange rate appreciation to restore equilibrium.
The example that is often used with regard to this is Japan, which has had a structurally high current account surplus. Using the external balance approach, if that current account surplus is seen as unsustainably high relative to historical norms, it requires a rise in the yen’s real exchange rate to restore equilibrium. Barring periodic reversals, this is what we saw from 1971 to 1995. Since then, the yen has reversed course, not least because the strengthening of the nominal yen exchange rate to a record dollar–yen low of 79.85 caused such a real shock to the current account balance that it in turn required a significant real exchange rate depreciation to restore equilibrium once more.
Within the emerging markets, another good example is that of Russia. Before the Russian rouble crisis of August 1998, Russia continued to record significant current account deficits. The external balance approach suggested that at some point a real exchange depreciation would be required to restore equilibrium. However, the Russian rouble was pegged to the US dollar and in order to maintain that peg real interest rates were kept high. Eventually, the costs of defending the Russian rouble peg — yet another case of trying to have all three of monetary independence, reasonably high capital mobility and a fixed exchange rate regime — proved too much and the rouble was de-pegged and devalued, and for good value Russia defaulted on its domestic debt.

This mix of weighted-criteria process is sometimes called a beauty contest. It can be done in secrecy with sealed bids to only invited suppliers. Or it can have all interested suppliers bidding. The selection process is certainly more objective with the ‘lowest bid wins’, but it can leave out the user’s needs considerably. Therefore, the argument for user functionality has to be spelt out for all. You can include the system criteria, or priorities, you deem important.
