Since the employment of the floating currency system, the
movement of Rupiah currency is determined by the market mechanism, or in other
words, the fluctuation of currency depends on the supply and demand in money
market. The study uses multiple linier regression analysis, in which the
independent variables are the difference of national income growth level(X1),
difference of inflation rate  (X2),
difference of interest rate  (X3)
in Indonesia and United States of America, while the dependent variable is the
fluctuation of Rupiah against US dollar (Y), and another independent variable
is the prior currency  (t-1) (X4).
The result of the study indicates that (X1), (X2),
(X3)
do  not have significant influence on the
fluctuation of Rupiah against UD dollar, while (X4) does. To sum up,
in addition to macroeconomic factors, non economic ones also influence the
fluctuation of Rupiah against US dollar.
