The case centers on an interest rate ceiling set collectively within AFPI’s code of conduct, initially 0.8 percent per day, later reduced to 0.4 percent. The anti-monopoly body stated the platforms breached Article 5, which prohibits agreements among competitors to fix prices in the same relevant market. Consequently, the KPPU imposed substantial fines, ranging from Rp 1 billion (US$59,000) to over Rp 100 billion, sending shockwaves through the digital economy.

Price-fixing is one of the most serious offenses in competition law. In many jurisdictions, it is treated as per se illegal because it replaces independent decision-making with collective control, theoretically harming the consumer by default. However, the fintech P2P lending context in Indonesia complicates this traditional doctrinal approach. By applying a rigid per se framework, the KPPU may have overlooked the broader "rule of reason," which allows for an analysis of whether a practice actually results in a net procompetition or public benefit.

While trade associations have long been viewed with caution, often seen as potential vehicles for coordination, this case does not arise from purely private, "smoke-filled room" coordination among competitors. AFPI operates under a formal co-regulatory framework supervised by the Financial Services Authority (OJK). The interest rate ceiling was not a predatory move to gouge consumers; rather, it was adopted in accordance with written directions from the OJK. These directions were issued amid mounting public concerns over predatory "loan shark" behavior, opaque fee structures and the potential for systemic consumer harm. In this context, the cap was a regulatory compliance measure intended to stabilize a nascent industry, not a mechanism to suppress competition.

The economic structure of fintech P2P lending further challenges a simplistic price-fixing narrative. Unlike traditional brick-and-mortar markets where firms might compete on a single, uniform price, these platforms rely on highly individualized, risk-based pricing driven by proprietary credit-scoring algorithms.

A shared maximum ceiling does not automatically produce identical pricing outcomes. If platforms retain autonomy over their datasets, machine learning models and underwriting parameters, substantial price differentiation continues to occur below the cap. In such an environment, competition naturally shifts from "headline rates" to the sophistication of predictive analytics, the efficiency of risk management, and the quality of the user experience. To view a maximum safety cap as a "fixed price" is to misunderstand the digital mechanics of modern lending.

More fundamentally, the KPPU’s decision turns on the definition of the "relevant market." The assumption that all 97 fintech platforms operate within a single, homogenous market deserves careful scrutiny. From a consumer perspective, Sharia-based profit-sharing platforms are not fully substitutable with conventional interest-based lenders. Similarly, a high-frequency, short-term consumer loan does not directly compete with medium-term productive financing aimed at micro, small, and medium enterprises (MSMEs).
