[Summary]

On June 2, 2026, according to multiple reports, the Japan Fair Trade Commission conducted on-site inspections of five major staffing agencies on suspicion of violating the Antimonopoly Act through unreasonable restraint of trade.

The focus of the reports is not necessarily the hourly wages paid directly to temporary staff. The issue appears to be alleged coordination over the staffing fees that staffing companies charge client companies. This distinction matters.

Staffing fees, however, include wages paid to workers, social insurance costs, training costs, and agency margins. If competition over staffing fees is distorted, it can affect not only client-company costs but also wage distribution and labor-market price formation.

This article uses the lens of New Price Formation Theory, or "price is power," to examine why parallel pricing in staffing markets can become an antitrust issue and who should decide the price of labor.

This article is based on public information available at the time of reporting and does not determine whether any specific company violated the law. On-site inspections are part of an investigation; whether there was an Antimonopoly Act violation will depend on future fact-finding.

New Price Formation Theory Series

We live surrounded by many prices: stock prices, hourly wages, interest rates, foreign exchange, and the value of data.

Who decides them, and under what rules?

This series reads modern capitalism through the question of who controls the rules of price formation.

In the capital markets chapter, we saw stock prices as a mechanism that prices future control.

Now we move to the labor market.

Behind daily attention to stock prices, or the price of capital, lies another large question: who decides the price of labor?

The reported focus is alleged coordination over staffing fees charged to client companies. The key point here is how that inter-company price problem connects to the formation of labor prices.

Which Price Is At Issue?

The first thing to check is the type of price involved.

Staffing services involve two major prices.

PriceWho pays whomMeaning
Staffing feeClient company pays staffing agencyTransaction price for staffing service
Hourly wage / wageStaffing agency pays workerCompensation to the worker

According to reports, the JFTC is looking at suspected cartel behavior over staffing fees received by staffing companies from client companies.

In other words, the central issue is not necessarily a direct agreement over the hourly wages of temporary staff. Writing this carelessly can easily distort the facts.

Still, staffing fees and wages cannot be separated.

If staffing fees rise, there should in principle be room to improve worker compensation. But if only staffing fees are raised in parallel while little is passed through to wages, client costs rise without meaningful income gains for workers.

Conversely, if competition for talent is truly working, agencies should improve hourly wages and conditions to attract better workers and then try to pass those costs on to client fees. If competition in staffing fees is distorted, the wage-competition channel can also weaken.

The market should not see this simply as a "staffing-company scandal."

It should ask how staffing fees, wages, margins, and client costs are actually formed.

Why Antitrust Law Enters The Labor Market

The Antimonopoly Act does not only protect consumers buying goods in stores.

It also protects the competitive process by which prices are formed.

If competitors agree on prices, quantities, customers, territories, or bidding conditions, the price no longer reflects free competition. This is why cartels and bid-rigging are treated as core antitrust issues.

Labor markets are no exception.

When companies compete for workers, wages and conditions should in principle reflect supply and demand, productivity, worker preferences, and bargaining power. If firms that should be competing coordinate fees or conditions, the market price can become distorted.

For investors, the important point is not only whether a company is fined.

If a business model has relied on limited competition, weak bargaining power among workers, or opaque fee structures, the normalization of competition can change margins, costs, and growth assumptions.

Staffing Fees Are a Hidden Price of Labor

The temporary staffing market is not a simple labor market where workers and companies negotiate directly.

The staffing agency stands between them.

The client company pays a staffing fee to the agency. The agency pays wages to the worker and covers social insurance, training, administrative costs, and its own margin.

This creates a layered price structure.

LayerWhat is priced
Worker wagePrice of labor supplied by the worker
Staffing feePrice paid by the client for labor plus service
Agency marginPrice of matching, administration, risk, and business operation

If fees are coordinated at the agency-client level, the distortion may not appear directly as a wage-fixing problem. But the effect can still reach the labor market.

Workers may not see how the fee paid by the client is divided. Clients may not know how much of the fee becomes wages. Investors may only see revenue and margins.

That opacity is why labor-market price formation needs to be read carefully.

The State Sets Rules, But Does Not Decide Every Wage

Who should decide wages?

In a purely market-based view, wages are decided by supply and demand. When labor is scarce, wages rise. When labor is abundant, wages fall.

But labor is not a normal commodity.

It is tied to people's lives, skills, health, time, family responsibilities, and bargaining position. A worker cannot store unused labor for later sale like inventory. Many workers also lack the bargaining power of a large company.

That is why the state enters the labor market through minimum wages, labor law, social insurance, antitrust law, and rules against unfair competition.

The state does not decide every wage. But it sets the floor and the competition rules under which wages should be formed.

The labor-market chapter therefore shows a different price-formation structure from capital markets.

Capital markets price future expectations. Labor markets require the state to maintain the rules under which competition can be considered fair.

Conclusion: Wages Are Prices, But Not Just Prices

Who decides the price of wages?

The answer is not one actor.

Workers, companies, staffing agencies, client firms, regulators, and market conditions all shape it.

But the key point is this: wages are prices, yet they are not just prices.

They are tied to people's livelihoods. If the competitive process behind them is distorted, the effect spreads beyond corporate margins to household income, labor mobility, and social trust.

In capital markets, the market prices future control. In labor markets, the state must ensure that the rules of competition are not broken.

Price formation here is not a simple victory of market freedom.

It is a field where market competition and public rules must coexist.

Next: Financial Markets

The next price is interest.

Interest is the price of money.

It affects households, companies, banks, governments, stock prices, real estate, and foreign exchange at the same time.
