Retail Sales Expected to Grow 1.4%. Is Indonesian Purchasing Power Recovering?

Indonesian retail sales are expected to grow by 1.4% year on year in September 2026. Bank Indonesia forecasts the Real Sales Index, or RSI, at 221.3, slightly improving from growth of 1.3% in August and 1.1% in July.

The increase suggests that household consumption has not entered a broad contraction. Other Goods, Other Household Equipment, and Cultural and Recreational Goods were expected to support the annual increase.

A 1.4% reading is not sufficient to conclude that purchasing power has recovered evenly. The September figure remains a respondent forecast, the growth rate is modest, monthly sales are expected to fall by 2.3%, and consumers assessed current economic conditions less positively than they did one month earlier.

Purchasing power also extends beyond retail sales. Real income, employment, essential-goods inflation, debt payments, savings, and the distribution of spending across income groups must improve together before the recovery can be described as strong.

What Is Actually Expected to Grow by 1.4%?

Bank Indonesia uses the Real Sales Index to track retail-sales trends based on a survey of retailers. The index is intended to describe changes in real sales rather than growth caused only by higher prices.

Annual growth of 1.4% means the September 2026 RSI is expected to be 1.4% higher than in September 2025. It does not mean every store, region, or product category recorded the same increase.

The September figure is also not a final realization. Bank Indonesia describes it as an expectation, while the August reading has already been reported as an actual result. The September number may be revised when the next survey is released.

Annual and monthly comparisons also point in different directions:

• September RSI is expected to grow 1.4% year on year.

• September RSI is expected to contract 2.3% month on month.

• August RSI grew 1.3% year on year.

• August RSI increased 0.8% month on month after contracting 0.1% in July.

These movements are not contradictory. September sales can be higher than a year earlier while remaining lower than August 2026 because of seasonality and the fading Independence Day spending effect.

Why Do the Annual and Monthly Numbers Differ?

The annual rate compares September 2026 with September 2025. The monthly rate compares September 2026 with August 2026. The two baselines capture different economic conditions.

August benefited from spending associated with Indonesia’s Independence Day period. The RSI increased by 0.8% from July as demand remained relatively stable.

September did not receive the same seasonal support. Lower sales of Food, Beverages and Tobacco were expected to cause the 2.3% monthly contraction.

The composition indicates that the 1.4% annual increase is not based on broad gains across all categories. Several groups improved, while a major high-frequency consumption category weakened from the previous month.

Four Tests of a Purchasing-Power Recovery

Retail sales provide one view of consumption, but they cannot establish a full recovery on their own. Four tests help distinguish broad improvement from a limited increase.

A. Growth Must Spread to Essential Categories

The September increase was expected to come from Other Goods, Other Household Equipment, and Cultural and Recreational Goods. These categories suggest that demand for household products and leisure-related purchases has not disappeared.

Food, Beverages and Tobacco were the main source of the expected monthly decline. Weakness in a frequently purchased category deserves attention because essential spending is closely linked to household cash flow.

A stronger recovery would normally involve more balanced gains across food, clothing, vehicles, household equipment, and recreational goods.

B. Income Must Outpace Living Costs

Purchasing power does not depend on nominal income alone. Households gain real spending capacity when income grows faster than the prices of the goods and services they consume.

Statistics Indonesia reported annual inflation of 3.28% in September 2026. Core inflation stood at 2.84%, while monthly inflation reached 0.30%.

The 1.4% RSI growth rate should not be directly subtracted from 3.28% inflation because the RSI is a real-sales measure, whereas the Consumer Price Index measures price changes. The two indicators should still be assessed together to understand the pressure on household budgets.

Inflation concentrated in food, housing, transport, education, or health can feel more severe than the national headline rate. Lower-income households devote a larger share of income to essentials and therefore have less room for discretionary spending.

C. Current Conditions Must Catch Up with Expectations

Bank Indonesia’s Consumer Confidence Index stood at an optimistic 118.1 in September 2026. A reading above 100 indicates that respondents remain broadly optimistic.

Its components present a more cautious picture. The Consumer Expectation Index rose from 127.6 to 128.7, while the Current Economic Condition Index declined from 109.4 to 107.5.

Consumers therefore became more optimistic about the future while assessing present conditions slightly less favorably than in August. That gap helps explain why retail sales continued to grow without accelerating sharply.

Expectations translate into spending only when households have adequate income, employment, and financial certainty. Optimism without stronger payment capacity may generate spending intentions that are not fully realized.

D. The Improvement Must Last Beyond One Month

The RSI grew by 1.1% in July, 1.3% in August, and is expected to grow by 1.4% in September. The sequence shows gradual improvement rather than a sudden surge.

Three months of consistent direction provide a more useful signal than one isolated reading. The pace remains modest because the growth rate increased by only 0.3 percentage points between July and September.

A more convincing recovery would require stronger growth that persists after holidays and temporary stimulus effects fade. Final September data and the October and November readings will show whether the improvement can continue.

Why Can Households Still Feel Financial Pressure?

Aggregate retail sales can rise when some consumers increase spending even if other groups remain under pressure. The survey does not directly identify who is spending, how much they earn, or whether purchases are funded through income, savings, or debt.

Households also consume different combinations of goods and services. A family spending most of its income on food, rent, transport, and education can face greater pressure than a consumer with substantial discretionary income.

Debt servicing is another factor. Stable income may not produce higher consumption if a large share is allocated to mortgages, vehicle loans, credit cards, or other borrowing.

Consumers can also adjust where and how they shop. They may move from traditional stores to e-commerce, switch from premium brands to cheaper products, or buy smaller package sizes. Transactions still occur, but those changes may indicate budget pressure rather than an improvement in welfare.

What Does the Data Mean for Businesses and Investors?

Low but positive retail growth suggests that domestic demand remains active. Consumer companies are not facing an aggregate contraction, although pricing power and sales volumes may differ widely across sectors.

Practical implications include:

• Essential-goods retailers should monitor sales volumes, package-size changes, and shifts toward lower-priced brands.

• Discretionary-goods companies may benefit from consumer optimism but remain vulnerable if real incomes fail to improve.

• Household-equipment producers may receive support from one of the categories driving September RSI growth.

• Banks and finance companies should distinguish spending supported by income from spending excessively dependent on credit.

• Consumer-stock investors should examine volumes, margins, inventory, and same-store sales rather than relying only on nominal revenue.

Sales generated through heavy discounts may not improve profitability. Volume can increase while margins decline because of promotional costs, raw materials, logistics, or currency depreciation.

The Data Needed to Confirm a Recovery

A purchasing-power recovery becomes more convincing when several indicators move in the same direction. The next assessment should include:

• Final September RSI data.

• October and November RSI growth.

• Sales of food, clothing, vehicles, and household equipment.

• Food and core inflation.

• Real wages and job creation.

• The Current Economic Condition Index.

• Consumer-credit growth and repayment quality.

• Household savings by account-size group.

• Retail-company sales volumes rather than rupiah revenue alone.

The signal would be stronger if real retail sales increased, essential-goods inflation remained controlled, current economic conditions improved, and consumption did not depend excessively on borrowing.

Has Purchasing Power Recovered?

The expected 1.4% retail-sales increase shows that consumption remains resilient and is improving slightly from the previous two months. It supports the conclusion that purchasing power is not experiencing a broad collapse.

“Recovered” would still be too strong if it implies a broad and even improvement. September remains a forecast, annual growth is modest, monthly sales are expected to decline, and the Current Economic Condition Index has weakened.

A more balanced conclusion is that purchasing power is showing signs of stabilization with gradual improvement. Confirmation requires broader growth across essential categories, several months of persistence, and stronger real income.

October and November will provide the next test. Continued positive growth after seasonal effects fade would strengthen the recovery case. Renewed weakness in food sales, current economic conditions, or retail volumes would show that the improvement remains fragile.
