Abstract EN:

The lebanese crisis adminated in a civil war that started since 1975. Moreover it was the source of other crisis. The economic and the monetary crisis should be viewed in this context. On the other hand and within the same context, the adaptation of the governements econolmic intervention policy worsened. Since then the exchange rate of the lebanese pound has suffered not only because of the political, economic, and monetary crisis but also because of mal adaptation of the governements economic intervention policy as mentionned earlier. Hence, it can be deduced that the governements economic intervention policy is in crisis. The keynesian approch of state intervention followed by the governement since 1975 could not confront the soci-economic problems, butinsteed it was a cause of the suddin drop in the exchange rate of the lebanese pound. The central bank of lebanon which was pressed to follows similar keynesian policies started, commencing in 1982 to impliment some monatary policies, inspite of the crisis and the urgent needs of country which appeared in lebanon. The maladaption of the governement's economic intervention policies which contined to exist made the monetary policy to be inadequate to confront the crisis of this magnitude. Nevertheless, thes monetary policies seem to curry hope, at least, because of the effective intervention instruments
