When people buy securities for the first time, they often think of a broker in much the same way as they think of a bank.
If a bank takes your deposit, it is responsible for holding your money. So if a broker helps you buy a bond or a share, it may seem logical to assume that the broker is also responsible for the company or institution behind that security.
But that is not how financial markets work.
A broker is a professional intermediary that gives investors access to exchange-traded and over-the-counter securities markets. Depending on its licences and the services it provides, a broker may offer access to financial instruments, assess whether certain instruments are appropriate for a client's regulatory status, accept and execute orders, arrange settlements, maintain records, safeguard assets and provide information and technological infrastructure.
What a broker does not do is take over the investor's responsibility for deciding whether a particular investment is worth making—or assume the risks associated with the issuer of that security.
That distinction matters.
Understanding where a broker's responsibilities end and an investor's responsibilities begin is essential for setting realistic expectations and making informed investment decisions.
What does a broker do?
A broker's role can broadly be divided into several areas.
1. Provides access to the securities market
For most private investors, direct access to securities markets is not possible—particularly when trades are executed through a stock exchange.
Stock exchanges do not deal directly with millions of individual investors. Instead, they work with licensed market participants that:
- hold the necessary regulatory authorisations;
- are connected to trading systems;
- meet financial stability, compliance and security requirements.
This is where the broker comes in.
As a professional market participant, the broker provides investors with access to securities transactions and executes their orders in accordance with applicable laws and regulations.
Where a broker operates its own trading platform and has the necessary technological infrastructure, it may also provide online access to available securities, facilitate trading and support market liquidity.
2. Executes transactions
The broker handles the operational side of investing. Depending on the scope of its services, this may include:
- providing access to trading;
- checking whether an instrument is available to a particular client under applicable requirements;
- accepting and executing client orders;
- arranging settlements;
- maintaining transaction records;
- providing reporting to clients and regulators.
In other words, the broker makes it possible for an investor to access the market and complete transactions efficiently and within the relevant regulatory framework.
It also provides the post-trade infrastructure that supports those transactions after they have been executed.
3. Safeguards securities, where it holds the appropriate depository licence
Another common misconception is that an investor's securities are simply “held by the broker”.
That is not how the system works.
Securities are recorded in an investor's own securities account and belong to the investor.
Ownership is reflected through the depository system, which may be connected to the National Depository of Ukraine and/or the depository system of the National Bank of Ukraine for certain government and municipal securities. These activities operate within the relevant regulatory framework and under the supervision of the National Securities and Stock Market Commission.
This means that client securities:
- are not part of the broker's own assets;
- are accounted for separately from the broker's proprietary assets;
- cannot simply be treated as the broker's property.
That is why the broker's own financial position should not be confused with the value or ownership of an investor's securities.
4. Provides information
A broker must provide clients with sufficient, clear and accurate information to help them understand:
- what they are buying;
- how and where a transaction is being executed;
- how much it costs;
- what risks may be involved.
Clients should also receive the relevant reporting and transaction documentation.
Depending on the broker and the services provided, a broker may also offer:
- market analysis;
- macroeconomic research;
- investment commentary;
- recommendations or other investment-related information.
But there is an important distinction between providing information and making the investment decision.
Unless an investor has explicitly delegated portfolio management or discretionary authority under a specific agreement, the final decision remains with the investor.
What is a broker not responsible for?
This is where many misunderstandings begin.
The issuer's reputation and financial health
A broker does not create the company that issued a security.
It does not run that company.
It does not make its management decisions.
And it does not control its business performance.
If a company issues corporate bonds or other securities, the fact that those securities are available through a broker does not mean that the broker guarantees the company's future success.
Compliance with the regulatory requirements applicable to securities issuance and market admission falls within the framework overseen by the relevant regulator—in Ukraine, the National Securities and Stock Market Commission.
There is one important distinction to make.
If a broker also acts as an underwriter during a primary offering, its responsibilities may include ensuring that investors receive the required information about the securities and the issuer, as well as complying with rules governing how and to whom those securities may be offered.
However, once the securities have been issued, responsibility for ongoing reporting and for servicing the issuer's obligations remains with the issuer itself.
The issuer's obligations under the securities
Interest payments, dividend payments and repayment of principal are obligations of the issuer.
For government bonds, the issuer is the state.
For corporate bonds or shares, the issuer is the company that issued the securities.
A broker may facilitate access to these instruments, but it does not replace the issuer as the party responsible for meeting its financial obligations.
Future investment returns
No professional market participant can guarantee future investment performance.
Markets involve risk.
Past performance—no matter how strong—does not guarantee future results.
A security may have delivered attractive returns in the past and still perform differently in the future.
That is true for individual shares, corporate bonds, funds and virtually every other market-based investment.
The role of a broker is not to eliminate market risk. Its role is to provide investors with access to the market and the infrastructure needed to invest.
So, why do you need a broker?
It is a fair question.
The value of a good broker is not that it chooses investments instead of you.
Its role is to create a reliable, transparent and convenient environment for investing—while operating within the legal and regulatory framework designed to protect investors and support orderly markets.
A good broker:
- provides access to a broad range of financial instruments available in the markets where it operates, subject to applicable restrictions;
- ensures that instruments and transactions meet relevant regulatory requirements;
- executes transactions efficiently and properly;
- provides information and research to support decision-making;
- helps clients understand how investing and financial markets work;
- provides reliable post-trade servicing.
In other words, a broker does not simply tell you which companies are “good” and which are “bad”.
It gives you the tools, information and infrastructure to make your own informed decisions and build a portfolio that reflects your objectives and risk tolerance.
What is the investor responsible for?
The investor ultimately decides:
- which securities to invest in;
- how much risk to take;
- how diversified the portfolio should be;
- how long to invest for;
- whether to trust a particular issuer.
Before investing, it is worth considering factors such as:
- the issuer's financial position;
- its credit rating, where available;
- the terms of the securities and the relevant offering documentation;
- the company's operating history;
- the risks facing its industry and business model.
This analysis is an essential part of making an investment decision.
The broker can provide information and access to the market, but it cannot make risk disappear.
Why can't a broker offer only the “best” securities?
Investors sometimes say:
“If a broker offers a security, surely that means the broker believes it is reliable.”
Not necessarily.
Securities that are admitted to the market must meet the applicable legal and regulatory requirements. But regulatory admission or compliance with formal requirements is not the same thing as a guarantee of future investment quality or performance.
That is why a professional broker does not simply decide which companies are “good enough” for investors.
Its role is to provide access to instruments that can legally be offered and traded within the relevant market framework, while giving investors the information they need to make their own decisions.
The investor then evaluates whether a particular instrument fits their objectives, expectations and tolerance for risk.
Conclusion
Successful investing depends on a clear division of responsibilities.
The broker is responsible for providing market access, properly executing transactions, safeguarding securities where it holds the appropriate depository licence, and delivering reliable client service.
The investor is responsible for choosing investments, assessing risks and making the final investment decisions.
The issuer is responsible for meeting its obligations to the holders of its securities.
This division of roles is one of the foundations of a functioning securities market.
Understanding it helps investors set realistic expectations, avoid common misconceptions and make more informed decisions.
And one more important point: issuers operate in many different industries. Under a modern regulatory framework, securities may only reach the market through the relevant legal and regulatory processes.
A broker's role is not to act as a moral judge of every issuer or industry. That is not what a broker is designed to do.
The broker's responsibility is to operate within the regulatory framework, provide lawful access to the market and give investors the information and infrastructure they need to make their own decisions.
The responsibility for evaluating whether a particular investment is right for you ultimately remains yours.
