The findings matter as Indonesia aims to transition into a high-income nation by its centennial in 2045. Economic growth alone is not enough; it must be stable, inclusive, and resilient. Inflation directly affects purchasing power, while household consumption remains the largest contributor to the country’s Gross Domestic Product (GDP). Together, these factors determine whether growth benefits all segments of society.
Economic Pressures and Policy Challenges
Indonesia’s economic landscape has been shaped by fluctuating commodity prices, rising fuel costs, and global uncertainty. These pressures have pushed up living expenses and weakened household purchasing power, particularly among lower-income groups. Small businesses also face higher production costs, limiting their ability to expand.
At the same time, inflation serves as a key signal of macroeconomic stability. When inflation rises uncontrollably, it disrupts savings, investment decisions, and long-term planning. However, extremely low inflation or deflation can also indicate weak demand and underutilized economic capacity. This creates a policy challenge: maintaining inflation at a moderate, stable level that supports growth without harming consumers.
How the Study Was Conducted
The research uses a qualitative descriptive approach, combining literature analysis with real-world insights from policymakers. The authors conducted in-depth interviews with officials from Indonesia’s Ministry of Trade between February and April 2026.
These interviews explored experiences in managing inflation, promoting investment, and coordinating economic policies. The research team analyzed the data using thematic coding, identifying patterns that explain how inflation control and consumption interact to influence economic growth.
Key Findings: Stability and Spending Must Work Together
The study finds that inflation control and household consumption are deeply interconnected and must be managed simultaneously. Key insights include:
- Stable inflation protects purchasing power and builds confidence among consumers and investors.
- Household consumption is the main engine of Indonesia’s economy, driving aggregate demand.
- Targeted fiscal policies, such as social assistance and subsidies, help sustain productive consumption.
- Investment expands production capacity, reducing inflationary pressure while supporting growth.
- Income inequality weakens consumption impact, limiting inclusive economic progress.
Recent data reinforces these findings. As of March 2026, Indonesia’s Household Consumption Index (IKRT) increased by 0.53% month-on-month, indicating modest growth in spending. However, rising prices of essential goods—such as rice, chicken, and eggs—have reduced real purchasing power for many households.
This creates an uneven recovery. While middle- and upper-income households may increase discretionary spending, lower-income groups are forced to cut back or switch to cheaper alternatives. As a result, overall consumption growth remains fragile and unevenly distributed.
Real-World Impact: Why This Research Matters
The implications of this study extend beyond academic analysis and directly inform economic policy. For governments, the findings emphasize the importance of coordinated fiscal and monetary strategies.
Maintaining inflation within a target range requires more than adjusting interest rates. It also involves:
- Strengthening social protection programs to support vulnerable groups
- Designing tax policies that do not overly burden low-income households
- Investing in infrastructure and supply chains to stabilize prices
- Supporting food security to prevent spikes in essential goods
For businesses, stable inflation creates a predictable environment for investment and expansion. Companies can plan long-term strategies with greater confidence, leading to job creation and increased productivity.
For society, protecting purchasing power ensures access to essential services such as education and healthcare. Stable consumption also supports domestic demand, which is critical for sustainable economic growth.
Expert Insight
Sepni Yanti from the University of Borobudur Jakarta explains that price stability plays a central role in economic confidence. She notes that when inflation is controlled, households can maintain consistent consumption, which in turn drives demand and supports long-term investment.
This perspective underscores a key message of the study: economic growth is not just about increasing output, but about ensuring that growth translates into improved welfare for all citizens.
Toward Inclusive Growth by 2045
Indonesia’s path to becoming a developed nation depends on its ability to balance macroeconomic stability with inclusive development. The study highlights that growth driven by consumption must be supported by policies that reduce inequality and strengthen human capital.
Investment in infrastructure, education, and healthcare will play a crucial role in increasing productivity and expanding economic opportunities. At the same time, managing inflation remains essential to prevent erosion of real incomes.
The research also points to the need for better data and future studies that capture regional differences and sector-specific dynamics. This will help policymakers design more targeted and effective interventions.
