Quick verdict: what the Capital Market Authority actually controls
The Capital Market Authority is the government body that supervises, develops and regulates the Saudi capital market. It issues the laws, regulations and instructions needed to apply the market law, with the aim of building trust, fairness and efficiency in the issuance of securities.
It also enforces fairness and full disclosure in joint-stock companies and protects investors and market participants. Its headquarters is in Riyadh.
Structure at a glance
| Entity | Function |
|---|---|
| Capital Market Authority | Regulator and supervisor of the market |
| Saudi Exchange (Tadawul) | Only entity authorized to list and trade securities |
| Securities Depository Center (Edaa) | Deposit, transfer, settlement and ownership registration |
How the Capital Market Authority was established
Saudi share trading began informally in the 1950s and stayed that way until the government issued foundational market regulations in the 1980s. The authority itself was created under the Capital Market Law, issued by Royal Decree No. M/30 dated August 1, 2003.
It holds financial and administrative independence and reports directly to the Prime Minister. Current rules and circulars are published by the Capital Market Authority.
Powers held by the Capital Market Authority
Its powers cover regulating and developing the market, improving the methods used by institutions involved in securities trading, and protecting investors from unfair practices including fraud, deception, manipulation and insider trading.
It also sets controls to reduce risks in securities transactions, regulates issuance and trading, supervises the entities under its authority, and monitors disclosure of information about securities and their issuers. That disclosure mandate is what makes listed company data usable for anyone comparing the largest companies in Saudi Arabia.
Saudi Exchange, known as Tadawul
Tadawul is a closed joint-stock company and the only entity authorized to list and trade securities in the Kingdom. It is the official source for information on executed transactions in the market.
It is an affiliate member of the International Organization of Securities Commissions, and a member of the World Federation of Exchanges and the Arab Federation of Exchanges. Its international profile grew after the market opened fully to global investors.
The Securities Depository Center Company, Edaa
Edaa is a single-person closed joint-stock company wholly owned by the Saudi Tadawul Group. It is the sole entity handling deposit, transfer, settlement and registration of ownership for Saudi securities traded in the market, under the Capital Market Law and its related regulations.
In plain terms, Tadawul is where the trade happens and Edaa is where ownership is recorded.
Where it sits in the wider system
The authority works alongside fiscal institutions covered in the Ministry of Finance overview and planning bodies such as the Ministry of Economy and Planning. Budget context appears in the 2026 budget figures.
For individuals, market regulation connects to everyday money decisions covered in personal finance in Saudi Arabia, while foreign investors often review the investor residency program.
Final verdict
Think of three layers: the authority writes and enforces the rules, Tadawul runs the trading venue and Edaa keeps the ownership record. Knowing which layer handles your question saves a lot of time.
