Abstract: We propose a method for jump point detection by wavelets. The observation model is assumed to be a deterministic function with an additive stationary noise. The detecting method is applied to the daily exchange rate of the US Dollar against Deutsche Mark in the period 1989-08-01 to 1991-07-31. All the points detected by our method reflect very strong economic and political impacts.

Key words: wavelets, jump points detection, exchange rate
