Understanding how financial markets are structured is essential for anyone entering the world of trading or investing. In fact, market structure refers to the environment in which securities are bought and sold — including how they’re issued, where transactions take place, and who the participants are.
Therefore, we break it down into two major areas:
- Primary Market vs. Secondary Market
- Exchanges vs. Over-the-Counter (OTC) Markets
A. Primary Market vs. Secondary Market
Primary Market
The primary market creates and sells financial instruments for the first time. Moreover, it’s the space where companies, governments, or other entities raise capital by issuing new securities directly to investors.
Key Features:
- Involves the issuer and the first buyer.
- Helps companies or governments raise fresh capital.
- Common instruments: IPOs (Initial Public Offerings), government bond auctions, private placements.
Example:
When Aramco issued shares for the first time in its IPO, investors who bought those shares participated in the primary market. Consequently, the funds went directly to the company.
Secondary Market
The secondary market allows investors to buy and sell securities among themselves, after they have been issued in the primary market. In this case, the issuing entity does not take part in these transactions.
Key Features:
- Offers liquidity – investors can sell their holdings.
- Prices fluctuate based on supply and demand.
- Most trading activity happens here.
Example:
If you buy shares of Apple on the NASDAQ, you’re participating in the secondary market. Here, you’re buying them from another investor, not from Apple directly.
B. Exchanges vs. Over-the-Counter (OTC) Markets
Exchanges
Exchanges are centralized marketplaces where securities, commodities, or derivatives trade in a regulated and transparent environment. Furthermore, they create trust and transparency for all participants.
Key Features:
- Standardized contracts and rules.
- Prices are publicly available and transparent.
- Trades clear through centralized clearinghouses.
Examples:
- New York Stock Exchange (NYSE) – USA
- London Stock Exchange (LSE) – UK
- Dubai Financial Market (DFM) – UAE
- Australian Securities Exchange (ASX) – Australia
- Amman Stock Exchange (ASE) – Jordan
Benefits:
Therefore, exchanges offer higher trust, price transparency, and investor protection.
Over-the-Counter (OTC) Markets
OTC markets are decentralized. Securities trade directly between two parties, often through dealers or brokers, without a formal exchange. However, this flexibility comes with additional risks.
Key Features:
- Less regulated, more flexible terms.
- Common for currencies, bonds, derivatives, and cryptocurrencies.
- Higher counterparty risk compared to exchanges.
Examples:
- Forex market – currencies trade globally OTC.
- Cryptocurrency platforms like Binance and Kraken operate in hybrid models (exchange + OTC).
- Corporate bond trading often happens OTC via broker-dealers.
Benefits:
As a result, OTC markets allow customizable contracts, access to niche instruments, and often greater anonymity.
