With regard to volatility, the analysis indicates that exchange rate volatility is probably not
a major policy concern. From the perspective of enhancing trade, the effects of lower volatility are
indirect, and originate from long-term exchange rate commitments such as currency unions and
pegged exchange rates rather than short-term exchange rate fluctuation. The limited importance of
exchange rate volatility is possibly related to the increasing availability of financial instruments to
hedge against exchange rate risks (e.g. forward contract and currency options) and to the increasing
share of intra-industry trade.
This study also finds evidence supporting the argument that trade policy is used to
compensate for the effect of an overvalued currency. However, the policy response seems to be
largely restricted to anti-dumping interventions. The evidence of a response in terms of a slower
pace in tariff liberalization is more muted. Although this correlation should be better investigated,
if confirmed it may have repercussions for the multilateral trade liberalization process, as large
exchange rate misalignments may reduce the incentives to remove existing trade barriers. Of
greater concern is that those results imply that persistent exchange rates misalignments may
increase incentives to recur to non-traditional protectionist policies.
More generally, this research carries three broader policy implications. First, whether
determined by exogenous shocks or by policy, policymakers need to pay attention to exchange
rates of their countries and those of other countries as the effect of currency misalignments on
international trade is considerable. This implies that countries should monitor their exchange rate
relative not only to that of their trading partners but also in relation to that of their competitors.
Second, exchange rate misalignments cannot explain the full extent of global imbalances.
Therefore, exchange rate adjustment can be only part of the solution for global rebalancing and
needs to be accompanied by other policy actions. Finally, strategies to avoid the resurgence of
trade protectionist measures should include multilateral cooperation related to the stabilization of
exchange rates towards their equilibrium level.
