A conditional variance analysis is applied to study the exchange rate of the Czech crown. The crown is pegged to a currency basket with an imposed narrow band. The central bank’s consistent policy enables the semi-fixed exchange rates to behave similarly to free ones. Their movements exhibit strong nonlinear dependency which is accounted for by an employment of the GARCH(1,1) model with daily dummies. The nonparametric BDS test proclaims accuracy of the model that filtered out nonlinearity and captured a forecastable structure present in the data.
