Brokerage house vs a bank — how investing differs

Definition

You can run a brokerage account at a bank's brokerage arm (a unit within the bank, e.g. the "BM" at your bank) or at a separate brokerage house (a standalone company — often a specialist broker). The service is similar, but a few things differ in ways worth understanding — without indicating what is "better".

What it means in practice

• Cash protection can differ. Cash on the brokerage account is covered by the KDPW compensation scheme (not the deposit guarantee) — regardless of whether the broker is part of a bank. But if funds sit on a linked bank account (typical in some bank brokerage services, e.g. eMakler), that part may fall under the BFG deposit guarantee up to EUR 100,000. Confirm the account structure with the broker.
• IKE/IKZE. IKE/IKZE accounts are offered mainly by Polish brokerage houses and bank brokerage arms; foreign brokers usually do not.
• Range of markets and costs. Specialist brokers can be cheaper or broader on foreign markets; bank brokerage arms can be convenient thanks to integration with your account. This differs per offer, not "by definition".
• Tax settlement. Polish entities (both bank-based and standalone) usually issue a PIT-8C; foreign brokers usually do not.

Why it affects your choice

"My bank has a broker too" does not mean the offer is the same as at a specialist broker — and vice versa. Differences in commission, markets, account currencies and IKE/IKZE can be real. We show them as fields, not as a verdict.

How to check this in our comparison

The Investing lens has, for each entry, a "Type" field (bank with brokerage activity / brokerage house), cash and securities protection, commission, markets, IKE/IKZE and settlement — with source and date. Order is alphabetical, not a ranking.

Watch out

Differences depend on the specific offer, not on "whether it's a bank". Confirm the cash-account structure (where cash sits and how it is protected) with the broker. Investing carries the risk of losing capital regardless of who runs the account.

We do not give investment advice and do not indicate the "better" form. Investing involves the risk of losing capital. Confirm the structure and protection of your account with the broker. WTP Finance is for information only.
