What Is the DSE and How Does It Actually Work?

The Dar es Salaam Stock Exchange (DSE) is Tanzania’s organised market for listed shares and bonds. It brings buy and sell orders together, publishes market prices and supports electronic settlement after a trade. Investors use licensed brokers to reach the market; they do not trade directly with the exchange.

What the DSE is—and what a share means

A share is one unit of ownership in a company. If a company has one million equal shares and you own one, you own one-millionth of that company. This ownership can carry rights described by the company and the law, such as voting or receiving a declared dividend.

A dividend is part of profit that a company chooses to distribute to shareholders. It is not guaranteed. A company may make no profit, retain its profit or stop paying dividends.

The DSE provides the rules and systems for trading listed securities. “Listed” means the security has been admitted to the exchange under stated requirements. The DSE does not set a permanent fair price, guarantee a buyer or protect a share from losing value. See why share prices move.

How the DSE matches buyers and sellers

An investor gives a buy or sell instruction to a licensed broker. The broker checks the order and enters it into the DSE’s Automated Trading System. This electronic system is the order book where eligible offers meet.

A buyer can state the highest price they will pay. A seller can state the lowest price they will accept. A trade happens when compatible orders meet under the exchange’s price and time rules.

Suppose one investor offers to buy shares at 500 TZS each. A seller asking 520 TZS has not matched that order. If an eligible seller accepts 500 TZS, the system can execute the trade.

The DSE then publishes trading information, including prices, quantities and market indices. An index combines price movements from a group of shares to show how that part of the market changed. It is a measurement, not a product guarantee.

Who handles each part of a DSE trade

Several participants have different jobs:

• Listed companies issue shares or other securities and publish required information.
• Investors decide whether to place buy or sell orders and accept the resulting risk.
• Licensed brokers, also called licensed dealing members, receive orders and enter them into the trading system.
• The DSE operates the market, matches orders and publishes trading data.
• The CSD and Registry Company (CSDR) maintains the electronic ownership records and supports settlement.
• CMSA, the Capital Markets and Securities Authority, regulates Tanzania’s capital market and licenses intermediaries.

The CMSA register identifies licensed brokers and other market participants.

The CDS account holds the securities after settlement. Money moves separately through the broker’s trust account or the DSE mobile platform’s payment instructions. Read How to Open a CDS Account in Tanzania for the account-opening steps.

DSE trading hours and settlement times

The DSE FAQ states that equity-market trading runs from 10:00 a.m. to 4:00 p.m. daily.

Execution and settlement are different events. Execution is the moment a buy and sell order match. Settlement is the later exchange of money and legal ownership.

Under the DSE and CSD Rules with 2025 amendments, equities settle on T+3 and bonds on T+1. “T” is the trade date. T+3 means the equity settlement is scheduled three settlement days after the trade date.

After settlement, CSDR debits the seller’s CDS account and credits the buyer’s account with the traded securities.

How large the DSE was at the end of 2025

Market capitalisation is the combined market value of the relevant listed shares. It changes when share prices or the number of listed shares changes. It is not the amount of cash held at the exchange.

The DSE’s fourth-quarter 2025 statement reported total market capitalisation of 23.99 trillion TZS, up 34.29% from 17.87 trillion TZS in 2024.

The DSE Market Performance Report 2025 reported that the All Share Index rose 29.08%, from 2,139.73 to 2,761.93. The index includes domestic and cross-listed companies, so it does not mean every share gained 29.08%.

That report also recorded 740,639 unique CDS accounts at year-end. It says 123,547 new accounts opened during 2025, a 316.28% rise from 29,679 new accounts in 2024. Investors aged 21–30 represented 40.33% of the new accounts. Read why investment accounts are growing.

Verification note: DSE’s separate Q4 statement reports 126,704 new CDS accounts for 2025. The total account figure and age share come from the dedicated market-performance report. Confirm the new-account total with DSE before publication.

More accounts do not prove that all account holders traded or made money. Account growth measures access and registration, not investment results.

Why a rising market can still lose you money

An index can rise while some individual shares fall. Your result depends on what you buy, the price paid, fees, timing and whether a buyer is available when you want to sell. A company can weaken or fail, causing a permanent loss.

This illustration excludes fees and dividends:

Illustrative holding	Amount
100 shares bought at 500 TZS	50,000 TZS
Value after price falls to 400 TZS	40,000 TZS
Reduction in market value	10,000 TZS

The 10,000 TZS decline exists even though the investor still owns 100 shares. Selling would turn the lower market value into a realised loss. Holding longer does not guarantee recovery.

Liquidity is another risk. It describes how easily a security can be sold without accepting a large price reduction. A listed share may have few interested buyers, so an order can remain unfilled.

What to do next

• Learn what a share, dividend, broker and CDS account mean before placing an order.
• Verify the broker in the live CMSA register.
• Read the company’s latest reports and announcements on the DSE website.
• State the quantity and price conditions clearly when instructing a broker.
• Keep payment records, the contract note and your CDS statement.
• Check all fees before trading and keep money needed for daily expenses separate.
• Use the Money Words dictionary for unfamiliar terms.

Frequently asked questions

Can I buy shares directly from the DSE?

No. Investors access secondary-market trading through a licensed broker. The DSE operates the market and trading system.

Does opening a CDS account mean I own shares?

Not by itself. An empty CDS account is only an ownership record ready to receive securities after a purchase or allocation.

What does T+3 settlement mean?

It means an equity trade is scheduled to settle three settlement days after the trade date. Execution happens first; ownership and payment are completed during settlement.

Why can my order remain unfilled?

There may be no seller or buyer accepting your price and quantity. Trading rules and the order’s position in time also affect execution.

Can a DSE share lose all its value?

A share can lose a substantial amount and the loss can be permanent. Listing and regulation do not guarantee company performance, dividends or a future buyer.
