Authority & scope
Sections ↑Turkey’s Capital Markets Board—Sermaye Piyasası Kurulu or SPK—regulates and supervises capital-market institutions, public offerings, collective investment structures and related market activities. The Borsa İstanbul, Takasbank, Merkezi Kayıt Kuruluşu and Investor Compensation Center perform separate market, clearing, recordkeeping or compensation functions.[1][2][7][8]

Registers & licence checks
Sections ↑Checking an intermediary
| Check | What to establish |
|---|---|
| Legal entity | Match the company in the account agreement to the CMB investment-institution record.Source 3 |
| Authorised activity | Check whether the entity may execute orders, deal, provide investment services or perform another named activity.Source 3 |
| Investor record | Use MKK services to review central records where applicable; a platform balance alone should not replace the official record.Source 7Source 4 |
| Sanctions | Search the named party and read the decision date, legal basis and procedural status.Source 5 |
Check the exact legal entity, permissions, current status and scope in the official record. A brand connection in our coverage does not establish authorisation.
Rules for firms & products
Sections ↑The governing duties depend on the account, market, product and client category. Securities brokerage, exchange derivatives and cryptoasset services are not interchangeable permissions. A group company’s registration should not be transferred to another company or product without evidence.[1][3]
Operational evidence to retain
| Area | Record or document |
|---|---|
| Orders | Order ticket, execution confirmation, time and market.Source 2 |
| Cash and settlement | Broker statement, bank route and clearing record.Source 2 |
| Custody | MKK or other applicable central record and beneficial-owner details.Source 7Source 4 |
| Borrowing or short sales | Separate agreement, collateral and risk rules.Source 2 |
Client assets & protections
Sections ↑Central registration and custody can support reconciliation of securities ownership, but they do not guarantee a security’s price. Cash, securities, cryptoassets and leveraged positions can follow different custody and failure arrangements.[7][4]
Protection boundaries
| Measure | Value | Context |
|---|---|---|
| MKK record | Evidence of dematerialised securities records within its system | Source 7 |
| Market loss | Not covered simply because an intermediary is licensed | Source 2 |
| Compensation | Requires the statutory trigger and current Investor Compensation Center process | Source 8 |
Complaints & dispute resolution
Sections ↑Escalating an account problem
| Stage | Action |
|---|---|
| Firm first | Send a written complaint to the named intermediary with evidence and requested remedy.Source 2 |
| Market institution | Use the exchange, clearing or recordkeeping route when the issue belongs to that institution.Source 2Source 7 |
| CMB submission | Use the Board’s official investor/contact route for regulatory matters within its remit.Source 2Source 6 |
| Legal claim | Private damages, limitation periods and binding outcomes can require courts or other procedures.Source 2 |
Report misconduct, scams or an unlicensed service
Sections ↑Use the CMB’s official institution records and sanctions database before relying on an investment website or app. A copied company name, registration number or logo does not authenticate the communication. Keep URLs, messages, payment instructions and account records when reporting suspected misconduct.[3][5][6]
Compensation & firm failure
Sections ↑YTM administers compensation after the CMB makes the relevant decision for an investment institution unable to meet covered cash-payment or securities-delivery obligations. The protection concerns assets held or managed in connection with investment and ancillary services. It excludes ordinary price losses and losses arising from investment advice.[9]
Investor compensation: amount and claim route
| Subject | Published rule |
|---|---|
| 2026 maximum | TRY 2,065,145 for each eligible investor. The statutory base amount is revalued annually; the 2026 figure is not a perpetual fixed limit.Source 10 |
| Aggregation | All claims against the same institution are combined, regardless of account number, type or currency.Source 9 |
| Claimant exclusions | Specified directors, managers, owners, related persons and group companies are excluded, as are persons responsible for or benefiting from the financial difficulties. Relevant criminal-proceeds claims are also excluded.Source 9 |
| Filing clock | Submit a written claim to YTM with evidence of entitlement within one year after announcement of the compensation decision, following the notice’s instructions.Source 11Source 12 |
| Destination | Use YTM’s official announcement and the form or submission procedure it identifies for the institution concerned.Source 11 |

Enforcement, changes & background
Sections ↑The administrative sanctions database is a dated enforcement source. Read the exact decision and later developments before describing a person or institution. A sanction, investigation and final judicial outcome should not be merged.[5]
A current example is YTM’s 28 October 2026 notice concerning Tera Yatırım Menkul Değerler AŞ. It records cancellation of that company’s activity permissions, investor compensation and gradual liquidation under the CMB’s 27 October decision. Claim forms and further instructions will be published by YTM. The notice gives investors 30 days from publication of the creditors’ schedule to object to their listed claims; that objection period is separate from the general compensation-claim window.[13]
