The threshold effect of monetary policy on the nominal and real economic variables through the credit channel in Iraq has been investigated using the threshold structural vector autoregressive model from 1970-2018. The results showed that the threshold of money growth in the nominal sector (inflation) is 3.13% and in the real sector is 9.76 % per year. Also, the impact of monetary policy values above the threshold on the real sector (economic growth) through the credit channel This shows a statistically significant relationship, and values below the threshold have been confirmed only in the long run. In the nominal sector, the effect of the monetary policy above the threshold is only confirmed in the short run, and below the threshold values are This shows a statistically significant relationship.
