The legal framework governing the crypto asset market in Türkiye has undergone a significant transformation with the regulatory changes introduced on 13 March 2025. Under this new framework, the activities of crypto asset service providers are no longer assessed in isolation but must be evaluated in light of a set of interrelated regulations, including the Communiqué on the Working Procedures and Principles and Capital Adequacy of Crypto Asset Service Providers (III-35/B.2), the Communiqué on the Establishment and Operating Principles of Crypto Asset Service Providers (III-35/B.1), the Communiqué on the Establishment and Activities of Investment Firms (III-39.1), and the Communiqué on Principles Regarding Information Systems Management (VII-128.10).

Taken together, these regulations signal a clear shift: the crypto asset market in Türkiye is moving away from a largely self-driven and autonomous structure, and is instead being redefined within the boundaries of the traditional financial system. This series aims to examine these communiqués as a coherent whole.

Communiqué No. III-35/B.2 sets out the scope of activities that crypto asset service providers may carry out, the framework within which such activities must be conducted, and the capital adequacy requirements applicable to these entities.

In doing so, the Communiqué treats crypto asset platforms not merely as technical infrastructure providers, but as regulated institutional actors operating within clearly defined activity boundaries and assuming corresponding legal responsibilities.

When Articles 5 through 9 of the Communiqué are considered together, it becomes clear that the market is not simply being regulated; its underlying operational logic is being redefined.

Article 5 introduces a closed list of permissible activities. These include intermediary services for trading transactions, the execution of transfer processes, the provision of custody services, and, in certain cases, intermediation in initial offerings or distributions.

At first glance, this may appear to be a purely technical delineation. In substance, however, it reflects a fundamental policy choice. By limiting activities to an expressly defined set, the regulatory approach abandons the previously dominant notion that “anything technically feasible may be offered.” Instead, it establishes a system in which only explicitly permitted activities may be carried out. In other words, the boundaries of what platforms cannot do are now as clearly defined as what they can.

Article 6 forms the core of the new framework. Under this provision, any activity listed in Article 5 may only be carried out on a regular commercial or professional basis with prior authorization from the Capital Markets Board.

This represents a decisive shift away from a technology-driven approach towards a permission-based system. The prevailing logic is no longer what is technically possible, but what is legally authorized. As such, the ability to operate is now contingent upon both technical capability and regulatory approval.

Articles 7 and 8 regulate the extent to which platforms may provide services beyond their core activities, as well as the conditions applicable to such services.

While platforms are not entirely prohibited from expanding beyond their primary scope, such expansion is subject to regulatory oversight and, in many cases, the knowledge or supervision of the authority. In this respect, the regulator does not seek to narrow the market outright, but rather to introduce a controlled degree of flexibility. That said, this flexibility is neither open-ended nor unconditional; it is carefully circumscribed by defined limits and supervisory mechanisms.

Article 9 is particularly noteworthy. It establishes a framework governing the activities of crypto asset service providers based abroad and effectively brings such activities within the scope of regulatory control.

By subjecting services directed at persons resident in Türkiye to certain conditions, the regulation creates a practical limitation on the ability of foreign platforms to access the Turkish market freely. Although this does not amount to an explicit prohibition, it is likely to produce a rebalancing effect in favour of locally licensed actors.

When these provisions are assessed collectively, the conclusion is clear: the crypto asset market is being restructured into a system where activities are clearly defined, restricted, and subject to a licensing regime. In this sense, the Communiqué goes beyond being a mere regulatory text; it establishes the foundational framework that determines who may operate in the market, under what conditions, and to what extent.

When Articles 5 through 9 are considered together, the impact of the regulation extends well beyond the mere licensing of activities. It introduces a structural transformation that directly reshapes the balance of the market.

The clear definition of activities and their subjection to licensing requirements directly addresses long-standing concerns around trust in the crypto asset market. By requiring service providers to operate within a defined legal framework, the regulation enhances transparency and oversight, thereby strengthening the protection of client assets, transaction security, and operational discipline.

From this perspective, the approach adopted by the Communiqué constitutes a critical threshold in terms of investor protection. Areas that were previously left largely to contractual arrangements are now subject to direct regulatory supervision.

At the same time, the introduction of licensing requirements and the limitation of activities create a significant barrier to entry. Providing crypto asset services is no longer a matter of technical capability alone; it now requires an approved institutional structure, financial strength, and organizational capacity.

This is likely to make market entry more difficult for small and medium-sized players. Conversely, for well-capitalized and institutionally structured actors, the result may be a more predictable and protected competitive environment. Over time, the market is therefore expected to consolidate around a smaller number of licensed and institutional participants.

The regulation introduced under Article 9 carries particular significance in terms of market impact. By bringing the activities of foreign service providers within a regulatory framework, it directly or indirectly restricts their ability to offer services to Turkish residents.

Although not an outright ban, this approach effectively limits access to the Turkish market for foreign platforms. It also rebalances competition between licensed domestic actors and unregulated foreign providers. This has a dual effect: on the one hand, it strengthens the position of local licensed platforms; on the other, it may indirectly restrict users’ access to global markets.

In this respect, Article 9 can be seen as a regulatory intervention that redraws both the geographic and competitive boundaries of the market.

Taken together, these developments present a clear picture. The crypto asset market in Türkiye is no longer merely regulated; it has been fundamentally restructured.

The definition of activities, the introduction of licensing requirements, and the partial limitation of cross-border access collectively point to a transition towards a more controlled, predictable, and institutionalized market structure.

However, this transformation also comes at a cost. The flexibility and accessibility that once characterized the market are inevitably constrained. The regulatory model adopted by the Communiqué therefore represents a dual dynamic: it strengthens investor protection while simultaneously reshaping the very nature of the crypto asset market. This tension is likely to be one of the defining features of the market in the period ahead.
