📋 What You Need Before You Start
Before opening a trading account, make sure you have the following ready:
| Requirement | Details |
|---|---|
| Valid ID | Cambodian national ID card or valid passport (for foreigners) |
| Passport‑sized photo | 4 × 6 cm (two copies recommended) |
| Bank account | A local bank account in Cambodia (for funding your trading account) |
| Minimum deposit | Varies by broker – from US$50 to US$1,000 (or US$0 for some international brokers) |
| Investor ID | Issued by the Securities and Exchange Commission of Cambodia (SECC) – your broker can help you apply |
⚠️ Important: Foreign investors can absolutely buy stocks on the CSX. The process is the same as for Cambodian citizens, but you will use your valid passport instead of a national ID card.
👤 Step 1: Obtain Your SECC Investor Identification Card
Every investor trading on the CSX must have an Investor Identification Card issued by the Securities and Exchange Commission of Cambodia (SECC). This card is valid for up to 20 years and costs only 20,000 riel (approximately US$5).
Option A: Apply Online (Recommended)
The SECC has launched an online application portal. You can now apply for an Investor ID from anywhere without visiting an office in person.
How to apply online:
- Go to the SECC online application portal at
https://id.serc.gov.kh/kh. - Fill in your personal information (name, date of birth, contact details).
- Upload the required documents:
- Copy of your national ID card (for Cambodians) or passport (for foreigners)
- One 4 × 6 cm passport‑sized photo
- Copy of your bank passbook (local or overseas account)
- Submit the application and pay the 20,000 riel fee (payment methods vary by portal).
The online application is faster and eliminates the need for face‑to‑face interactions, making it especially convenient for foreign investors or those outside Phnom Penh.
Option B: Apply Through Your Brokerage
Most securities firms will handle the SECC application for you when you open a trading account. This is the simplest route for beginners. Simply provide your broker with the required documents, and they will submit the application on your behalf.
Documents required for SECC application:
- Completed SECC Application Form (Form A)
- One copy of your ID card (Cambodian) or passport (foreigner)
- One 4 × 6 cm photo
- One copy of your bank passbook (any currency)
Once submitted, your Investor ID card should arrive in approximately one week, though it may take longer during busy periods (such as before an IPO).
🏛️ Step 2: Choose a Licensed Securities Firm
Cambodia has a number of SERC‑licensed securities firms that are members of the CSX. Below are some of the most well‑established options for 2026.
| Securities Firm | Key Features | Minimum Deposit |
|---|---|---|
| ACLEDA Securities Plc | Fully online account opening via mobile app; seamless integration with ACLEDA Bank accounts | Low |
| Cambodia Securities Plc | Full‑service investment bank; offers advisory, research, and trading services | Varies |
| Campu Securities Plc | Online account opening via Phsarhun app (iOS/Android) | Low |
| Cana Securities Ltd. | Competitive fees; straightforward application process | Varies |
| PPLink Securities Plc | Holds three SERC licenses (Securities Broker, Derivative Broker, Securities Selling Firm) | Varies |
| Royal Securities Plc | No minimum fee; 0.5% brokerage fee for stock trading, 0.2% for bonds | US$50 |
| SBI Royal Securities Plc | Established firm with strong parent backing; research department available | Varies |
| Yuanta Securities (Cambodia) Plc | Part of a major regional financial group; experienced management | Varies |
💡 Tip: As a novice investor in a frontier market, it is wise to choose a firm whose management or parent company has experience operating in larger regional exchanges. Also, consider whether the brokerage has its own research department – this can give you access to valuable market analysis to guide your investment decisions.
For foreign investors: Ensure the brokerage provides clear information and communications in a language you understand. Some brokerages may have specific rules for account ownership, and there may be disclosure requirements from tax authorities in your home country, so it pays to ask before opening an account.
📄 Step 3: Open Your Trading Account
Once you have chosen a securities firm and obtained your Investor ID (or applied for it through the broker), you can open your trading account. The process is straightforward and can often be completed online.
Required Documents
| Document | For Cambodians | For Foreigners |
|---|---|---|
| Identification | National ID card | Valid passport |
| Photo | 4 × 6 cm (2 copies) | 4 × 6 cm (2 copies) |
| Investor ID | SECC‑issued number (if already obtained) | SECC‑issued number (if already obtained) |
| Bank account info | Copy of bank passbook | Copy of bank passbook (local account) |
| Signature specimen | Required on application forms | Required on application forms |
How to Apply
Online (ACLEDA Securities, Campu Securities):
Several brokers now offer fully online account opening. For example, ACLEDA Securities allows investors to open a trading account directly via their smartphone, tablet, or PC from anywhere, at any time. Campu Securities offers a similar service through the Phsarhun mobile app.
In person or by mail:
Traditional brokerages may require you to submit physical copies of the application form and supporting documents. Your broker will guide you through the process.
What you will sign:
You will be asked to sign a client agreement, account opening form, and investor ID form (if you do not already have an SECC‑issued ID). You will also need to provide a signed authorisation letter to allow transfers between your bank account and your trading account.
💰 Step 4: Fund Your Trading Account
After your trading account is approved, you need to deposit funds before you can buy shares.
Minimum Deposit Requirements
| Broker Type | Typical Minimum Deposit | Notes |
|---|---|---|
| CSX local brokers | US$50 – US$1,000 | Royal Securities has a low minimum of US$50 |
| International brokers (global stocks) | US$0 – US$100 | Interactive Brokers has US$0 minimum |
How to Fund Your Account
- Transfer funds from your local bank account into the brokerage’s designated cash collection account. Your trading account is usually linked to a riel‑denominated savings account at the brokerage’s affiliated bank.
- Once the funds are received, they will be credited to your trading account.
- For CSX trading, you must deposit 100% of the purchase price of any shares you wish to buy before placing an order. Your cash and securities are then frozen for settlement.
⚠️ Important: You cannot buy shares on margin (borrowed funds) on the CSX. You must have the full amount of cash in your trading account before placing a buy order.
📱 Step 5: Start Trading
Using the CSX Trade Mobile App
The CSX has launched an upgraded CSX Trade mobile app, available on both iOS and Android. The app allows you to:
- Place buy and sell orders
- View real‑time stock quotes
- Check current and historical market data
- Monitor your trading account balance
How to access the app:
You can download the CSX Trade app from the Apple App Store or Google Play Store. Some brokers (such as ACLEDA Securities) also offer CSX trading directly through their own mobile banking apps.
Placing an Order – Step by Step
- Log into your trading platform (CSX Trade app or your broker’s portal).
- Select the stock you want to buy or sell.
- Choose your order type (market order or limit order).
- Enter the number of shares you wish to trade (minimum 1 share).
- Confirm the order.

| Continuous trading (morning) | 9:00 AM – 11:30 AM |
| Continuous trading (afternoon) | 1:30 PM – 3:00 PM |
| Closing session | 3:00 PM |
How Orders Are Processed
- You can place orders via the Mobile Trading System (MTS) or through your broker (by writing, voice, or electronic means).
- Once your order is successfully placed into the CSX trading system (T+0), your cash or securities are locked for settlement.
- Orders are matched in the CSX system according to predetermined auction principles.
- The CSX notifies the broker of trading results (T+0), and your broker confirms the results with you.
Settlement
- Settlement occurs two business days after the trade (T+2).
- On T+2, you pay cash (or deliver securities) through your broker, and your broker settles the trade on your behalf at the CSX.
💡 First‑time investor perk: The CSX continues to waive commission fees for first‑time stock investors, making it even more affordable to start your investment journey.

If you want to invest in global markets (US, Hong Kong, Singapore, etc.), you will need an international online broker, not a local CSX broker.

❓ Frequently Asked Questions
Can a foreigner open a stock trading account in Cambodia?
Yes. Foreigners can absolutely open a trading account and buy shares on the CSX. The process is similar to that for Cambodian citizens – you will need a valid passport (instead of a national ID card), apply for an SECC Investor ID, and open an account with a licensed securities firm. Foreign investors have grown from 5,189 to 6,413 in recent years, reflecting increasing international interest.
What is an SECC Investor ID and why do I need it?
The SECC Investor Identification Card is a mandatory requirement for anyone buying or selling stocks on the Cambodia Securities Exchange (CSX). It is issued by the Securities and Exchange Commission of Cambodia and is valid for up to 20 years. The card costs only 20,000 riel (US$5). You can apply online via https://id.serc.gov.kh/kh or through your brokerage.
How much money do I need to start investing?
It depends on your broker and the share price. For CSX brokers, minimum deposits can be as low as US$50 (Royal Securities). For international brokers, Interactive Brokers has a US$0 minimum deposit. However, you also need enough funds to purchase at least one share of your chosen company.
What are the trading fees on the CSX?
CSX trading fees are typically around 0.5% per trade, plus applicable VAT. However, first‑time investors may enjoy zero‑commission promotions (the CSX continues to waive commission fees for first‑time stock investors). Royal Securities, for example, charges 0.5% for stock trading and 0.2% for bond trading with no minimum fee.
How long does it take to open a trading account?
The entire process can be completed in as little as 1–2 weeks:
- Investor ID application: ~1 week (online may be faster)
- Trading account approval: 1–3 business days
- Funding: 1–2 business days for local transfers
Can I trade US stocks from Cambodia?
Yes. You can trade US stocks (and other international markets) using an international online broker such as Interactive Brokers, Tiger Brokers, or Saxo Bank. These platforms offer access to the NYSE, NASDAQ, Hong Kong Stock Exchange, and Singapore Exchange. Interactive Brokers is widely considered the best option for Cambodian residents due to its low fees and strong regulatory oversight.
Is my money safe with a Cambodian broker?
All licensed securities firms are regulated by the Securities and Exchange Regulator of Cambodia (SERC) and are members of the CSX. However, Cambodia does not have a deposit insurance scheme for brokerage accounts. To reduce risk, choose a well‑established firm with a strong parent company or regional experience, and consider diversifying your holdings across multiple brokers if you have significant assets.
