The economics of hidden costs – What business leaders need to watch

In 2026, the economy leaves little room for approximation

France is operating in an environment of weak growth, still-volatile inflation, more selective financing conditions and increasing pressure on margins.

The Banque de France has lowered its forecast for French economic growth to 0.5% for 2026.

INSEE expects growth to remain limited to 0.7%, following a 0.1% decline in GDP in the first quarter of 2026.

At global level, the IMF forecasts growth of 3.1% in 2026, below the averages observed before the pandemic.

These figures are not simply macroeconomic data. They are changing the way businesses need to be managed.

When growth slows, poor decisions become more costly.

When inflation returns through energy prices, margins can shift more rapidly.

When interest rates remain high, every financing decision has a greater impact on the future.

When business failures exceed 70,000 over a twelve-month period in France at the end of April 2026, the financial strength of customers, suppliers and partners becomes a board-level issue.

In this environment, business leaders can no longer focus solely on visible costs. They must also examine invisible costs. These are often the factors that weaken a business before the financial statements reveal the problem clearly.

A weak economy exposes what growth used to conceal

When activity is expanding rapidly, certain weaknesses can remain absorbed by revenue growth.

An overly complex organisation can continue to function.

Insufficiently analysed margins can be offset by higher volumes.

Poorly anticipated cash flow can remain manageable thanks to the steady inflow of new sales.

An unprofitable customer can remain in the portfolio without immediately triggering concern.

But in a low-growth economy, those margins for error disappear.

Growth no longer absorbs internal inefficiencies.

It no longer masks delays in invoicing.

It no longer compensates for poorly structured contracts.

It no longer forgives delayed decisions.

This is precisely what 2026 is demanding from business leaders.

The issue is no longer simply about selling more. It is about understanding more precisely what each decision actually produces within the economics of the business.

A company can report stable revenue and still lose economic strength. Not because its market is disappearing, but because its invisible costs are increasing faster than its ability to manage them.

Invisible costs are economic before they are accounting costs

An invisible cost does not always appear as a separate line item in the income statement.

It may take the form of a quotation that takes too long to approve.

A contract accepted with an insufficient margin.

A customer retained out of habit despite requiring disproportionate internal resources.

A team operating without sufficiently clear performance indicators.

A business leader forced to intervene in too many operational decisions.

Reporting delivered after the point at which it would have been useful.

These costs are rarely dramatic at first. But they accumulate.

They reduce margins.

They consume management time.

They weaken cash flow.

They slow down decision-making.

They undermine execution.

They make the business increasingly dependent on a small number of key individuals.
In the financial statements, their effects often appear too late.

In the financial statements, their effects often appear too late.

Margins deteriorate.

Profit declines.

Cash flow becomes strained.

Working capital requirements increase.

But the final figure does not always reveal where the company first began to lose value.

This is where economic analysis becomes critical.

The income statement tells you what happened. Strategic analysis must explain why it happened.

Inflation in 2026 is not simply a pricing issue

In 2026, inflation cannot be reduced to a general rise in prices. It acts as a stress test for the business model.

The European Central Bank forecasts inflation of 3.0% in the euro area in 2026, notably driven by energy prices. In France, the Banque de France expects headline HICP inflation of 2.5% in 2026, before easing to around 1.7% in 2027 and 2028.

For business leaders, this means one simple thing : it is no longer enough to observe that costs are increasing.

They need to understand which increases can be passed on, which must be absorbed, which require renegotiation and which reveal a structural weakness.

A rise in costs can expose an overly rigid pricing model, contracts that are insufficiently indexed, excessive dependence on certain suppliers, a lack of budget scenarios or margins that only remain viable in a stable economic environment.

Inflation should therefore be treated as a test.

It tests the quality of pricing, the resilience of margins, the ability to renegotiate, the speed of decision-making and the financial maturity of the business.

Financing is once again a strategic trade-off

For years, many companies operated in an environment where credit was relatively accessible. That cycle has ended.

In June 2026, the European Central Bank reported a deposit facility rate of 2.25%, a main refinancing operations rate of 2.40% and a marginal lending facility rate of 2.65%. These levels change the logic behind financing decisions.

Financing is no longer simply a resource. It is once again a strategic trade-off.

Borrowing, investing, hiring, restructuring debt, financing an acquisition or absorbing a temporary cash-flow gap do not produce the same consequences when the cost of capital rises and banks become more demanding about financial trajectories.

Business leaders therefore need to ask more rigorous questions.

Will the investment create clearly measurable future capacity?

Is financing being used to accelerate a strategy or to compensate for an operational weakness?

Is the cash requirement driven by healthy growth or by a model that consumes too much cash?

Will the level of debt still leave sufficient room for manoeuvre in two or three years?

Financing can provide short-term breathing room while reducing strategic flexibility over the medium term.

Business failures are changing the way risk must be assessed

At the end of April 2026, the Banque de France recorded 70,228 business failures on a cumulative twelve-month basis. This does not mean that all companies are at risk. But it is a reminder that economic risk spreads throughout the ecosystem.

A customer begins paying more slowly.
A supplier becomes financially weaker.
A subcontractor no longer has the capacity to deliver. A partner reduces its commitments.
A bank requests additional information.
A buyer demands greater guarantees.

Risk never remains isolated. It spreads through payment terms, commercial conditions, collections, negotiations, guarantees and investment decisions.

For business leaders, this requires a more rigorous analysis of receivables, payment terms, revenue concentration, supplier dependencies and contractual commitments.

Revenue does not have the same economic quality when it comes from financially solid, diversified customers who pay on time as when it depends on a small number of vulnerable accounts whose ability to pay is deteriorating.

Performance should therefore not be measured solely by the volume of activity. It must also be measured by the economic quality of that activity.

Management attention has become an economic asset

In a more constrained economy, one resource has become particularly critical: management attention.

It is consumed by key customers, teams, banks, recruitment, cash-flow pressures, regulatory obligations, commercial decisions, legal matters, taxation and organisational issues.

Every poorly prepared file consumes that attention.
Every unclear indicator disperses it.
Every delayed decision clutters it.
Every imprecise process diverts it from genuinely strategic priorities.

This cost does not immediately appear in the accounts. Yet it directly affects the quality of management and decision-making.

What 2026 requires from business leaders

The year 2026 reinforces a reality that periods of strong growth sometimes make easy to forget : a business cannot be managed solely through its final profit figure.

It must be managed through an understanding of its economic balance : margins, cash flow, payment terms, customer risks, exposure to external costs, ability to finance decisions, dependence on key individuals, speed of execution, quality of financial information and robustness of strategic choices.

In a more demanding economy, the companies that perform best are not necessarily those with the largest volume of data. They are those that can identify the right information, at the right time, to support the right decisions.

This is where financial advisory takes on its full value.

At KAERUS, we believe that financial statements should not merely report a situation. They should help explain the economic dynamics that produced it.

Invisible costs are not minor details. They are often the first signs of future imbalance.
Identifying them earlier means preserving freedom of action.
Addressing them means transforming financial information into a genuine management tool.
