Brokerage account versus CFD

This lesson explains the practical differences between a Polish brokerage account and a CFD broker, focusing on ownership, custody, costs, tax treatment, and protection. It is designed for someone who has heard both terms and wants to choose the right structure for the first live account.

Ownership and custody

In a brokerage account, you buy the actual security — a stock or an ETF. The broker acts as an intermediary, and the asset is held in custody, typically segregated from the broker’s estate. If the broker fails, the assets are not part of the insolvency estate, though recovery can be slow.

A CFD is a contract for difference. You do not own the underlying asset. You have a claim against the broker to pay the difference between the entry and exit price. If the broker fails, your claim depends on fund segregation and local investor protection. That is not the same as stock custody.

A side-by-side comparison is in CFD vs stocks.

Counterparty risk

The counterparty risk is higher with CFDs because the broker is the other side of the contract. With stocks, the counterparty is the market and the custody agent, not the broker’s trading book.

Costs

Brokerage accounts typically charge commission per trade, custody fees, and sometimes account maintenance fees. CFDs charge spread and overnight swap. The total cost depends on your trading frequency and holding period.

• A buy-and-hold investor pays commission once and custody fees periodically. Spread is irrelevant because there is no exit spread on the same day.
• A day trader pays commission twice per trade and spread twice per trade. Overnight swap is avoided by closing positions before the cutoff.
• A swing trader pays commission twice per trade and spread twice per trade, plus swap for each night the position is held.

To compare, calculate the round-trip cost for your typical trade on both structures. Use the same instrument and position size. The difference is often smaller than the marketing suggests, but it can be material for high-frequency strategies.

Leverage

In a brokerage account, leverage is limited by regulation and by the cash available in the account. In the EU, retail CFD leverage is capped at 5:1 for stocks and 2:1 for crypto. A brokerage account does not offer leverage by default unless you use a margin facility, which has its own rules and costs.

The advertised CFD leverage is a maximum, not a requirement. You can choose a smaller position size. The leverage slider on the platform does not change the economic risk if the stop distance is fixed.

Tax treatment

In Poland, profits from securities in a brokerage account are subject to capital gains tax (Belka), currently 19 per cent. The broker usually withholds tax at source on dividends and sometimes on gains, depending on the account type. You settle the difference in your annual tax return.

CFD profits are also taxable, but the treatment depends on the broker’s jurisdiction and your tax residency. Some brokers withhold tax at source; others require you to report gains yourself. The key point is that CFD tax treatment is less standardised than brokerage account treatment, and you should check current rules before trading.

Investor protection

Brokerage accounts in the EU benefit from investor compensation schemes, typically up to a defined limit per investor, under KNF supervision in Poland. CFDs are covered by similar schemes, but the coverage depends on whether the broker is regulated in the EU and whether client funds are segregated.

Negative balance protection applies to retail CFD clients in the EU. You cannot lose more than your deposit. In a brokerage account, the worst case is that the asset value falls to zero, but you do not owe the broker additional money.

The percentage of losing accounts is recorded in your method, never quoted from memory.

Which structure to choose

| Goal | Recommended structure | | --- | --- | --- | | Long-term investing in stocks or ETFs | Brokerage account | | Short-term trading with leverage | CFD with a regulated broker | | Tax-advantaged investing | Brokerage account with IKE or IKZE | | 24/7 access to crypto | Crypto exchange, not CFD | | Learning platform mechanics | Demo account on either structure |

The choice is not about which structure is better in general. It is about which structure matches your instrument, horizon, and risk tolerance.

Options are a separate product class, in which rights and obligations split differently; the mechanic of call, put, and multiplier is in What is an option.

Common mistakes

• Treating a CFD as a stock because the underlying is a stock. The legal and counterparty structure is different.
• Using a CFD for long-term investing because of leverage. Leverage amplifies cost and does not replace custody.
• Ignoring tax differences between structures.
• Assuming that a broker with a nice platform is supervised. Verify the licence separately.

Next step

If you choose a CFD broker, read the lesson Leverage and margin to understand stop-out distance. If you choose a brokerage account, read the lesson on order types to understand execution.

Practical comparison for the same position

To see the difference, compare buying 100 shares of a company in a brokerage account with buying 100 CFD contracts on the same company through a broker. In the brokerage account, you pay commission once on entry and once on exit, and you receive dividends directly. In the CFD, you pay spread on entry and exit, overnight swap for each night held, and any dividend is adjusted in the CFD price or paid with a potential withholding tax. The economic exposure can be similar, but the costs, counterparty, and tax treatment differ.

Checklist before opening the first live account

1. Verify the broker’s licence and supervision.
2. Confirm whether the account is a brokerage account or a CFD account.
3. Record the fee schedule: commission, spread, swap, withdrawal fees.
4. Check negative balance protection and investor compensation scheme coverage.
5. Understand the tax treatment for your jurisdiction and instrument.
6. Start with a demo account in the same structure you plan to use live.

This checklist is not optional. Skipping any item means you are comparing structures based on marketing, not facts.

Common questions

Can I buy an ETF through a CFD?

Technically yes (exposure to the ETF price difference), but that is not an ETF: you do not hold units, you hold an OTC contract. For long holding periods a brokerage account gives actual ownership.

What happens if a CFD broker goes bankrupt?

It depends on the jurisdiction and on fund segregation. Client funds are usually separated from the company's estate and covered by a compensation scheme — but the payout from that scheme is capped at a statutory limit. Check the current limit in supervisory materials and with your broker.

Will the compensation scheme cover my loss on a CFD?

No. The compensation scheme protects against the insolvency of an investment firm, not against trading losses. A disputed position close or a bad fill goes through a complaint, and then a regulator or a court. There is no automatic compensation.

Is CFD leverage always evil?

No — it is a tool with a price (margin, swap, liquidation risk). The problem is using leverage as a plan instead of sizing from your stop. See the lesson on leverage and margin.
