Abstract
The research primarily aims to analyse the relationship between the quantitative monetary policy tools and financial maturity criterion in Iraq. The study used annual data in the form of time series for the period (1990-2021), given that Iraq witnessed economic and monetary policy changes during this period. The study also aims to determine whether financial maturity is affected by changes in the quantitative tools of monetary policy. The research has adopted two approaches: The first includes the descriptive aspect, while the second relies on standard quantitative analysis, which involves developing the research model and then conducting the tests for the model depending on the Auto-Regressive Distributed lags (ARDL) model. The test results showed a positive significant relationship between the discount rate and financial maturity variable in the long term.
