Indonesia's 2026 Inflation: Balancing Targets and Reality

This figure remains within the inflation target range of 2.5 percent plus-minus 1 percent, specifically between 1.5 and 3.5 percent.

However, for economists, the issue is not merely whether inflation stays within the target bounds, but rather the direction of its movement and how the public forms expectations regarding future prices.

Moving Upward Within the Corridor

Throughout 2026, Indonesia's inflation has experienced dynamic movements. Inflation reached 3.34 percent in June before falling to 2.88 percent in July as food supplies improved.

However, inflation rose again in August to 3.19 percent, higher than the 2.31 percent recorded during the same period the previous year.

On a monthly basis, July saw a deflation of 0.14 percent, before reversing into an inflation of 0.21 percent in August. The price of broiler chicken was one of the primary contributors to the price increase that month.

By expenditure group, food, beverages, and tobacco were the main drivers of inflation, contributing 1.13 percent. The personal care and other services group contributed 0.63 percent, followed by transportation at 0.58 percent.

Meanwhile, the volatile food component volatile food was recorded as experiencing 6.24 percent inflation.

Another development that warrants close attention is core inflation, an indicator that relatively better reflects demand pressure and inflation expectations compared to seasonal price changes.

Core inflation rose to 2.92 percent in August, the highest level since March 2023. This condition requires vigilance because core inflation tends to be more persistent and takes longer to control.

Unlike food prices, which are heavily influenced by weather conditions and supply, core inflation can reflect broader price pressures, including changes in production costs, wages, and public expectations.

If this increase continues, the risk of a second-round effect second-round effect on prices and wages could also increase.

Future inflation risks have not fully subsided. Global commodity prices are expected to begin declining but remain above the previous year's levels. On the other hand, the potential for an El Niño phenomenon could disrupt rice and horticultural production.

In the context of monetary policy, Bank Indonesia reportedly raised the BI-Rate by 25 basis points twice in June, before maintaining it at the 5.75 percent level.

Nevertheless, interest rate policy is not always effective in addressing inflation stemming from supply disruptions.

Raising the BI-Rate can help manage inflation expectations, support the stability of the rupiah exchange rate, and control demand. However, such measures do not directly lower the prices of chili or chicken that rise due to weather and distribution disruptions.

Therefore, strengthening food supplies, improving logistics systems, and coordinating the Central Inflation Control Team (TPIP) and Regional Inflation Control Teams (TPID) remain essential parts of efforts to maintain price stability.

A Resilient Labor Market

Amidst inflationary pressure, Indonesia's labor market shows a relatively positive condition.

The Open Unemployment Rate (TPT) in February 2026 was recorded at 4.68 percent, a decrease of 0.08 percentage points compared to February 2025.

The addition of 1.896 million jobs also surpassed the growth of the labor force, which reached 1.862 million people.

Although the difference is relatively small, this condition signals that labor absorption is still occurring.

However, if future labor force growth exceeds job creation, the unemployment rate could potentially rise again and exert pressure on public purchasing power.

Beyond the number of jobs, the quality of employment also requires attention.

The number of informal workers reached 87.74 million, significantly higher than the 59.93 million formal workers.

Informal workers are still categorized as employed. However, some face issues of income instability, limited social protection, and vulnerability to changing economic conditions.

Thus, an unemployment rate of 4.68 percent does not fully reflect the quality of the national labor market.

A relatively low unemployment rate can still be accompanied by issues of underemployment, low productivity, and income uncertainty in the informal sector.

Reading Through Theory: The Phillips Curve and the Role of Expectations

The relationship between inflation trends and labor market conditions can be analyzed through the expectations-augmented Phillips curve expectations-augmented Phillips curve.

This approach, developed by Milton Friedman and Edmund Phelps, explains that actual inflation is influenced not only by labor market conditions but also by public expectations regarding future inflation.

Several studies in Indonesia have found a trade-off trade-off between inflation and unemployment, although the pattern of this relationship can change over time.

In the short term, the negative relationship between inflation and unemployment tends to be more visible. However, in the long term, adjustments in inflation expectations can weaken this relationship.

Globalization and technological developments can also influence the traditional relationship between inflation and unemployment.

Simply put, when workers and businesses anticipate that the prices of goods and services will rise, they tend to adjust their economic decisions.

Workers may demand nominal wage increases to maintain purchasing power or real wages. Meanwhile, companies may potentially raise selling prices to maintain profit margins amidst expectations of rising production costs.

If this condition occurs widely, expectations of price increases can contribute to driving actual inflation.

This phenomenon is known as the self-fulfilling expectation self-fulfilling expectationmechanism, a state where formed expectations actually contribute to the occurrence of the anticipated condition.

In the short term, there is an additional mechanism that explains the relationship between inflation and unemployment.

When actual inflation turns out to be higher than anticipated, nominal wages that were previously agreed upon may not immediately adjust.

As a result, real labor costs may temporarily decrease. Companies then have the opportunity to increase production and hiring, potentially causing unemployment to fall below its natural rate.

However, this effect is not permanent.

When inflation expectations begin to adjust, workers and companies will again adjust wages and prices. In the long term, the unemployment rate tends to return to its natural level, while inflation may persist at a higher level.

Therefore, the central bank has a significant interest in keeping inflation expectations aligned with established targets.

A Mirror of Indonesia's Data

Several of Indonesia's economic indicators show developments that can be interpreted through this theoretical framework, although they are not sufficient to prove a direct causal relationship.

The Consumer Confidence Index (IKK) in August 2026 was recorded at 118.5, up from 116.8 the previous month.

The index for job availability also increased from 101.1 to 104.1.

At the same time, the ratio of consumption to income increased to 74.2 percent, while the proportion of income saved fell to 15.8 percent.

This data may indicate that public optimism regarding economic conditions and job opportunities remains intact.

When people feel more confident about their jobs and income, the tendency to increase consumption can also strengthen.

Increased demand then has the potential to provide room for price increases, especially if not balanced by growth in the supply of goods and services.

This risk becomes greater when there are disruptions in food production, goods distribution, or energy supply.

However, there are two important notes in reading the relationship between inflation and Indonesia's labor market.

First, some of the inflationary pressure throughout this year stems from supply-side factors, such as changes in food prices and global commodities.

These factors cannot be fully explained through the Phillips curve, which focuses on the relationship between inflation, expectations, and economic activity conditions.

Second, the unemployment data used comes from the February 2026 survey, while the inflation changes analyzed occurred from June to August.

This difference in periods means the decline in unemployment in February cannot be directly concluded as the cause of the inflation increase in the following months.

To obtain a more accurate picture, additional analysis is needed regarding wage developments, core inflation, inflation expectations, and labor market conditions over comparable periods.

August labor data may provide further insight into labor market changes during that period.

Anchoring Expectations

The expectations-augmented Phillips curve theory provides an important lesson in inflation management.

As long as the public believes that inflation will remain controlled and return to the target, temporary price increases due to weather or global commodity volatility do not necessarily develop into persistent price and wage increases.

Conversely, if inflation continues to move toward the upper limit of the target and public expectations rise accordingly, price pressures can become increasingly persistent.

In such conditions, the credibility of monetary policy risks weakening, while the economic cost of lowering inflation in the future could become greater.

Therefore, inflation control requires a combination of mutually supportive policies.

Bank Indonesia needs to maintain the credibility of monetary policy and the stability of expectations, while the government needs to ensure the availability of food supplies, smooth distribution, and readiness to face climate risks such as El Niño.

Consistent and easily understood policy communication to the public is also an important part of maintaining confidence in economic stability.

Ultimately, the success of inflation control is measured not only by the ability to keep figures within the target range but also by the ability to maintain public purchasing power, labor market stability, and confidence in the direction of the economy.

Controlled inflation is not merely a matter of hitting statistical targets, but ensuring that the economic reality experienced by the public remains aligned with policy goals.
