With the inauguration of a new government, organizational restructuring follows to achieve its policy objectives. A notable change in the Lee Jae-myung administration's restructuring is the creation of an independent Planning and Budget Department by separating the planning and budgeting functions from the Ministry of Economy, which will contribute to a more agile response to the energy transition and other emerging issues. This shift is significant as it represents a move away from a traditionally bottom-up budget allocation method, which is often mired in rigid procedures that hinder responsiveness to new challenges.

Traditionally, the South Korean budgeting process relies on departments estimating their budget needs and submitting requests to the Ministry of Strategy and Finance, which then aggregates and adjusts these to fit the overall expenditure limit. This system has created bottlenecks where departments find it hard to adjust their budgets mid-cycle in response to unplanned urgent needs and has led to inefficiencies such as excessive demand and drastic cuts during negotiations. The new ministry aims to alleviate these issues by implementing a top-down approach that could better align budget allocation with strategic priorities and efficiency in financial operations.

In the context of rapid technological changes driven by AI and other factors, the previous budgeting methods have been recognized as insufficient. The example of the recent Russia-Ukraine war showcases how traditional military assets have become less effective in comparison to newly emerging technologies like drones, which suggests a need for more proactive and flexible budgeting approaches. The implementation of a top-down budgeting process is thus seen as an essential adaptation to ensure that governmental financial strategies can respond adequately to the volatile and unpredictable nature of contemporary challenges, including global conflicts and technological advancements.
