A Comparative Analysis of Effects of Borrowing from Central Bank, Bonds, and Islamic Treasury Bills to Finance Government Budget Deficit on Selected

The Iranian government has traditionally financed its budget deficit through borrowing from the Central Bank. In contrast, many countries rely on bonds as the primary method to finance the budget deficit. The Iranian economy rejects this method based on religious considerations. Islamic Economists in Iran have proposed an alternative financial instrument called the Islamic Treasury Bills, which inherently differ from bonds. This study analyzes and compares how borrowing from the Central Bank, bonds, and Islamic Treasury Bills as budget financing methods affect macroeconomic variables, such as inflation, investment, and gross domestic product. This study uses a Dynamic stochastic general equilibrium model (DSGE) for an open economy by considering various methods of financing budget deficit. Findings suggest that using Islamic Treasury Bills to finance the government's budget deficit is preferable to the two other approaches, i.e., borrowing from the Central Bank and issuing bonds.
