The investment budget is fundamental and efficient for managing a country's economic resources. It serves as a reflection of the country's intentions and priorities in directing investments toward the sectors that are most in need and of the most importance. Given globalization and the growing economic difficulties, there is a pressing need for efficient solutions to attain economic growth. This study emphasizes the significance of the investment budget as a fundamental tool in fostering economic growth. The investment budget in Iraq has become a crucial matter, particularly since 2003. It involves intricate dynamics between the pressing need for economic growth and the challenges the Iraqi economy faces because of the previous regime's legacy. These challenges have hindered the country's progress, leading to a decline and collapse, including infrastructure underdevelopment and widespread destruction. The Iraqi economy has been plagued by structural imbalances in its non-oil sectors and challenges stemming from a lack of investment allocations. Successive governments have failed to prioritize investment, crucial for expanding the production base and maintaining a balanced economy. Consequently, investment expenditures have not constituted a significant proportion of the overall economy.
