We investigate the time series generated by an elementary and deterministicfinancial process that consists in making monthly contributions to a savingsaccount subjected to the devaluation by a monthly negative real interest rate.The monthly contribution is a piecewise constant function of the accountbalance. We show that a dichotomy holds for such a financial time series:either the financial time series are asymptotic to finitely many periodicsequences or the financial time series have an uncountable (Cantor) set of{\omega}-limit points. We also provide explicit parameters for which thefinancial process is chaotic in the sense that the financial time series havesensitive dependence on initial conditions at points of a Cantor attractor.
