Abstract: Can nominal exchange rates be characterised by deterministic chaos? To answer this question, a statistical framework utilising blockwise bootstrap was used to test for the presence of a positive Lyapunov exponent in a time series. In most cases, the null hypothesis of a non-positive Lyapunov exponent characterising the time series was rejected.

Keywords: Deterministic chaos; Dynamical systems; Exchange rates; Moving blocks bootstrap.
