The scholastic view of public religion differed, and this difference was on two extremes. Alleconomic schools agreed that public debt is a monetary liquidity that was unjustly deductedfrom the income and output cycle as a result of the imbalance in the economic balance and thedeparture from the conditions of balance between aggregate demand and aggregate supply.Debt is a waste of financial resources allocated to productive accumulation. Except for theKeynesian school, which considers public debt to be an addition to aggregate demand after thedecline in the role of the private sector in investment as a result of pessimistic expectations thatwarn of signs of economic contraction. Public debt is linked to the exchange rate through theinterest rate channel, so that public debt causes competition for financial resources. Thiscompetition results in an increase in the local interest rate, which results in an increase indemand for the local currency with the aim of increasing investment, and the demand for thelocal currency raises the price of the local currency. Which means that there is an indirectrelationship between public debt and the exchange rate, but this relationship may create damagein the balance of payments in the near future. They assumed the existence of a long-term causalrelationship between internal public debt and the exchange rate. The main goal of this researchis to verify the economic relationship between the investigated variables, using thecointegration model and the error term correction vector model to prove the researchhypothesis. And the Kranger model of causality between the variables. The research reachedthe most prominent conclusion, which is that individual expectations for the internal publicdebt after each annual deficit in the state’s general budget cause a decrease in the value of thelocal currency due to the increase in demand for the dollar and the decrease in demand for thedinar, which means that there is causality in one direction. From internal public debt to theexchange rate, this is what was proven by the results of Kranger’s causality test.
