High Utilisation Is Not Enough to Justify Expansion

Business activity in Indonesia strengthened in the second quarter of 2026.

Bank Indonesia’s Business Survey recorded a Weighted Net Balance of 12.97%, up from 10.11% in the previous quarter.[1]

Production-capacity utilisation also rose to 73.80% from 73.33%.[1]

Investment remained strong as well.

Indonesia recorded Rp1,010.6 trillion of investment realisation in the first half of 2026, up 7.2% year on year.[2]

The macro signal is constructive.

For an individual company, however, the decision is much harder.

Does a busier operation mean it is time to expand?

Not automatically.

73.80% is not a universal red line

Ideal utilisation differs enormously across industries.

A factory, hotel, restaurant, warehouse and consulting business cannot use the same threshold.

One company may operate comfortably at 85%.

Another can experience service deterioration well below that.

The national figure provides context.

It does not provide a company-specific investment rule.

The increase is not uniform across sectors

Bank Indonesia reported that the Q2 increase in utilisation was mainly supported by agriculture, mining and electricity supply.[1]

That matters.

An aggregate increase does not prove that every manufacturer or retailer is running short of capacity.

Internal operating data remain more important.

Q3 activity is expected to remain positive—not surge

Survey respondents forecast Q3 business activity at a WNB of 11.75%, still positive but slightly below Q2’s 12.97%.[1]

That supports continued activity, not indiscriminate expansion.

Manufacturing is expanding too

BPS reported a Q2 manufacturing Business Condition and Prospect Index of 52.31, placing the sector in expansion territory.[3]

New orders, output and purchased inventories expanded.

Employment and supplier delivery-time components remained in contraction.[3]

The pattern suggests companies may still be trying to absorb demand through existing resources before adding permanent labour.

Busy does not mean constrained

A restaurant can be full on Friday night but empty on Monday afternoon.

A warehouse can be full during a holiday peak.

A factory can use overtime for three weeks.

None automatically justifies permanent capacity.

The first question is:

Where is the actual bottleneck?

Find the constraint before buying capacity

The bottleneck may be:

packaging;

quality control;

cold storage;

loading docks;

staff capability;

maintenance;

materials;

or transport.

If a packaging station limits total throughput, another production line may do little.

The cheapest expansion is often debottlenecking.

Aggregate utilisation can hide product-mix problems

A plant may operate at 80% overall.

One line is at 95%.

Another at 50%.

If demand has shifted toward the first product family, the company may need targeted capacity rather than a new plant.

The useful question is not:

“How full are we?”

It is:

“Which capacity is actually scarce?”

Demand needs to be durable

Capex creates long-term fixed commitments.

Demand can be temporary.

A seasonal surge.

One large project.

A competitor’s temporary outage.

A viral product.

A commodity cycle.

Permanent assets financed by temporary demand create overcapacity risk.

Companies need evidence that demand can repeat.

Order books beat enthusiasm

Management optimism is useful.

Committed demand is better.

Backlogs.

Contracts.

Repeat orders.

Pipeline conversion.

Customer churn.

Those indicators tell management whether utilisation has durable support.

Customer concentration matters

A facility can be operating at 90%, but if one customer represents 45% of volume, utilisation is fragile.

Before expanding, management needs to understand who is occupying the capacity.

Volume and concentration should be analysed together.

Capex costs more than the asset price

A new machine also brings:

installation;

training;

maintenance;

energy;

spares;

insurance;

working capital;

depreciation;

and financing costs.

Capacity decisions therefore require full-life economics.

Payback should be stress-tested

A three-year payback estimate is only as good as the assumptions behind it.

What volume?

What margin?

What utilisation?

What happens if demand is 25% below plan?

Every expansion case needs a downside scenario.

Producer costs are rising too

Indonesia’s general Producer Price Index increased 5.62% year on year in Q2 2026, while manufacturing producer prices rose 4.94%.[4]

Stronger demand therefore does not automatically mean stronger margins.

Capacity should create economic returns, not merely revenue.

Overtime can be a bridge

For a temporary demand surge, overtime may be cheaper than permanent assets and hiring.

But overtime has limits.

Fatigue.

Quality risk.

Safety.

Maintenance.

It works as temporary capacity—not as a permanent strategy.

Add shifts before adding plants

Unused night-time machine capacity can sometimes be monetised through an additional shift.

That requires labour and supervision but can avoid major capex.

The right answer depends on process economics.

Outsource before building

Contract manufacturing, third-party warehousing and subcontracting can provide flexible capacity.

They reduce fixed commitments.

The trade-off is less control, lower margin and increased dependency.

When demand visibility is weak, flexibility itself has value.

Leasing can preserve optionality

Warehouses, vehicles and even equipment can often be leased.

Ownership gives control.

Leasing can preserve flexibility.

Decision models should value that optionality rather than compare monthly payments alone.

People are capacity too

Service businesses face a different version of the same problem.

If consultant utilisation reaches 90%, should the firm hire?

The answer depends on sales pipeline, project duration, skill requirements and automation potential.

Hiring the wrong skill creates overcapacity just as easily as buying the wrong machine.

Automation can expand capacity

Capacity growth does not always require physical assets.

Scheduling automation.

Invoice automation.

Warehouse picking.

Routing.

Quality inspection.

Reducing setup time.

Each can increase throughput using the same asset base.

Productivity is another form of expansion.

Maintenance needs headroom

Management may be tempted to maximise utilisation.

But machines require maintenance.

Operations need buffers.

Running continuously near theoretical maximum can reduce sustainable output if downtime rises later.

Some unused capacity is operational insurance.

Working capital often becomes the real bottleneck

Higher production also requires more raw materials, inventory, receivables and logistics.

A company can buy a new machine and still be unable to fund the inventory needed to operate it.

CFOs need to model capex and working capital together.

Credit is available, but underwriting still matters

Bank Indonesia’s Q2 Banking Survey showed a sharp increase in new lending, with a WNB of 93.08%, and respondents expected continued expansion in Q3.[5]

At the same time, lending standards became slightly more prudent in Q2 across areas such as rates, limits, covenants and maturities.[5]

Financing availability therefore does not make every expansion project attractive.

Strong national investment is context—not a mandate

Indonesia’s first-half investment realisation exceeded Rp1 quadrillion.[2]

That is important macro evidence.

But companies should not invest simply because others are investing.

A national investment boom and individual overinvestment can happen at the same time.

Every capex project needs its own thesis.

Build the capacity the market actually needs

More capacity is not always the same as useful capacity.

A company may own plenty of equipment for Product A while demand grows in Product B.

A restaurant may have enough seats but an undersized kitchen.

A warehouse may have enough floor space but inefficient picking.

The question is:

capacity for what?

Scenario planning should be mandatory

At minimum, test:

Base case.

Upside case.

Downside case.

Then model cash flow, utilisation, break-even, working capital and debt-service capacity.

If the project works only in the upside scenario, it is probably too fragile.

Trigger-based capex improves discipline

Companies can set investment triggers.

For example:

utilisation above a defined level for six consecutive months;

backlog above a specified threshold;

lost sales exceeding a set amount;

a multi-year customer contract;

or outsourcing cost exceeding ownership economics.

The exact thresholds differ by business.

The discipline is what matters.

Think about exit value

What happens if the forecast is wrong?

Can the machine be sold?

Moved?

Repurposed?

Leased?

Specialised assets with no secondary market carry greater downside.

Residual flexibility should be part of the investment case.

Growth can come from productivity first

Before adding fixed assets, ask whether the current system can produce more.

Less downtime.

Higher yield.

Lower scrap.

Faster changeover.

Better scheduling.

A 10% productivity improvement can postpone a major investment.

Healthy macro data should support disciplined decisions

The Q2 picture is constructive.

Business activity rose.

Capacity utilisation increased.

Manufacturing expanded.

Investment remained strong.

BI respondents also described corporate liquidity and profitability as generally sound, with credit access remaining relatively easy.[1]

That does not mean management should rush.

Healthy conditions give companies room to choose carefully.

Six questions before expanding

Where is the actual bottleneck?

Is the demand durable?

Can productivity solve it first?

Can capacity be leased or outsourced?

What happens under a downside scenario?

Can cash flow fund both capex and working capital?

If those answers are unclear, waiting may be strategic rather than timid.

High utilisation is not the objective

The purpose of a business is not to run every asset at 100%.

It is to earn healthy returns while serving customers reliably and managing risk.

Sometimes that requires expansion.

Sometimes debottlenecking.

Sometimes outsourcing.

Sometimes no new investment at all.

Indonesia’s Q2 data show room for growth.

But room to grow is not the same as a requirement to build.

The best expansion happens when management knows exactly which capacity is scarce, which demand will fill it and what return the new capacity will generate.
