The short answer: forex is not banned in Türkiye, it is regulated. Leveraged trading may only be offered through SPK-authorized intermediaries; we list which firms hold that authorization on our SPK-licensed forex companies page.
What does the legislation say about foreign brokers?
The SPK’s investor booklet is direct: carrying out leveraged trading through institutions, entities or websites other than the intermediaries authorized by the Capital Markets Board “constitutes a breach of capital markets legislation”.
So softening this into “foreign brokers are a grey area” is not accurate. The Board’s enforcement targets the platform: when unauthorized activity is identified the site is blocked and a criminal complaint is filed. We track the blocked domains weekly in our SPK Bulletins archive.
What does SPK authorization actually give you?
SPK authorization is not an abstract badge but four concrete protections: leverage capped at 1:10, mandatory minimum margin and a suitability test, margins reported to the central clearing bank (Takasbank), and losses beyond your margin that cannot be demanded from you. The detail is in our 1:10 leverage cap article.
On top of that, there is an authority you can turn to. On an unauthorized platform there is no supervisor to appeal to; what remains is the prosecutor and — if you paid by card — your bank.
Is a foreign license enough?
Regulators such as the FCA, ASIC or CySEC provide serious oversight; however, those licenses do not bring SPK protection to an investor in Türkiye. In a dispute, the foreign authority and law apply, and recovery becomes harder. We compare what each regulator actually supervises in our regulators section.
Practical consequences
Trading with a foreign broker carries high risk: there is no local investor protection, and tax and legal processes are complex. Before you trade, check the broker’s SPK status and FX Trust Score in our broker directory; if you already have a problem, the order of applications is in our forex complaint guide.
