Exchange rates

Previous assessments of nominal exchange rate determination have focused on a narrow set of models. Using data for six currencies, this column examines the performance of an expanded set of models at various forecast horizons. No model consistently outperforms a random walk benchmark, although the purchasing power parity model does fairly well. Overall, combinations of model, specification, and currency that work in one period will not necessarily work well in another.

A border tax adjustment from origin-based taxation to destination-based taxation is under consideration for corporate profit tax in the US. This column investigates the implications of such an adjustment for the nominal exchange rate, assuming the real equilibrium of the economy is unchanged. While conventional wisdom is that the currency of the country implementing the adjustment will appreciate by a percentage equal to the VAT or corporate profit tax rate, a depreciation of the same magnitude is just as likely.

The rate at which consumer prices rise following a depreciation of the currency, known as the exchange rate pass-through, has been declining. The column uses a decomposition of exchange rate pass-through into the component that can be attributed to pricing of imported goods at the dock, and the second-round effects on domestically produced goods and services, to show that reductions in second-round effects are largely responsible for the decline in pass-through. Enhanced monetary policy credibility is strongly associated with this reduction.

Some exporters prefer to use most-favoured nation rates even when exporting to a fellow member of a free trade agreement. This column analyses the effect of exchange rates on the utilisation of free trade agreements, focusing on the ASEAN-Korea agreement. A depreciation of an (ASEAN) exporter’s currency against the (Korean) importer’s currency enhances utilisation rates of the trade agreement’s tariffs, with implications for the design of rules of origin.

Macroeconomic models have been criticised for their inability to forecast exchange rates better than the random walk model. This column argues that open-economy DGSE models are useful in forecasting the real exchange rate but not the nominal exchange rate, owing to their failure to capture adequately the international co-movement of prices. They correctly predict, however, that the bulk of the real exchange rate adjustment occurs through the nominal rate. The central role of the nominal rate in restoring price competitiveness in flexible exchange rate regimes can be exploited from a forecasting perspective.
