Exchange Rates and Parities

Exchange rates and parities correspond to the terms of trade between two currencies. Exchange rates refer to the amount of Chilean pesos per unit of foreign currency. Among these, the Observed Dollar (Chilean pesos per US dollar) stands out, which corresponds to the weighted average price of transactions carried out by banking companies on the previous business day. This indicator is used by different agents as reference for the valuation of assets and liabilities in foreign currency. On the other hand, parities correspond to the amount of a given country’s currency that is equivalent to one US dollar.

The Real Exchange Rate corresponds to the product of the observed nominal exchange rate and the external price index, deflated by the CPI. It is an index that measures the competitiveness of Chile in relation to its main commercial partners, using for its calculation the evolution of parities and inflation indexes of each of these countries.

The main trading partners considered for the calculation of the RER and their weights are available in "Weights by trading partner for Chile". This information is published annually on January 23, or the next business day.
