It is often argued that forward exchange rates should be unbiased predictors of future spot exchange rates if the foreign exchange market is efficient. Is this true or false?

The statement is false. Future spot exchange rates are based on economic predictions of economists, who consider all the possible alterations of the market in a given economy.

Explanation:

Future exchange rates are prices set by banks and other important economic actors, which regulate the value at which different currencies will be exchanged or certain goods will be bought. These future rates are set through an analysis of the political and economic situation of the market in which the exchange will take place, with the aim of ensuring competitive and efficient values in the face of the probabilities of market shocks, both internal and external.
