In short: Swiss investor protection starts by separating cash deposits from custody assets. Cash protection, segregated securities, broker supervision and foreign sub-custody are different questions that should be checked before funding an account.
Many investors ask whether a broker is "safe" as if safety were one feature. It is not. A safe setup depends on the legal entity, regulator, cash handling, custody chain, statements and what happens during failure or insolvency.
This guide explains the practical difference between cash and securities protection for Swiss investors.
Cash is not the same as securities
Uninvested cash is usually a claim on a bank, broker or cash partner. Securities held in a custody account are different. FINMA explains that custody account assets such as shares and fund units belong to the client and are segregated from the estate during bankruptcy proceedings.
That distinction is essential. A cash balance, an ETF, a Swiss share and a crypto asset can sit in the same app while having different legal and operational treatment.
Start with the legal entity
The app name is not enough. A global broker may onboard Swiss residents through a foreign entity, while a Swiss broker may use local banking infrastructure and foreign sub-custodians for some markets.
Record:
- legal entity name;
- regulator;
- country of account agreement;
- cash bank or cash partner;
- custody entity;
- market access route;
- complaint process.
This is the same first step used in the FINMA broker safety checklist.
What depositor protection covers
Swiss depositor protection is about eligible deposits, not investment performance. It does not protect against market losses, bad investment choices or a falling share price.
For an investor, the practical question is: what part of the account is cash, and what part is held as securities in custody?
If a broker account sweeps cash to a bank or money-market structure, the investor should read the official account documents, not only the marketing screen.
What custody segregation does
Custody segregation means securities should be separated from the bankrupt estate and returned to the client, subject to the applicable legal and operational process.
This does not remove every risk. Investors still need to consider:
- record accuracy;
- sub-custody chain;
- foreign market rules;
- securities lending;
- omnibus account structure;
- corporate action processing;
- account recovery timelines.
Segregation is a protection mechanism, not a promise that everything will be instant or frictionless.
Foreign brokers need extra mapping
A foreign broker can be suitable for Swiss residents, but the investor must map which protection scheme applies. Do not assume Swiss rules apply just because the client lives in Switzerland.
Check:
- account entity;
- regulator;
- cash protection scheme;
- securities segregation rules;
- tax reporting quality;
- access to SIX or Swiss securities;
- support if documents are needed for Swiss tax work.
This is why broker choice connects directly with the Swiss investor tax guide.
Red flags
Be cautious when:
- the legal entity is hard to find;
- the broker mixes cash yield claims with unclear custody language;
- statements do not show enough detail;
- the investor cannot identify the custodian;
- product marketing is louder than risk documentation;
- the platform pushes complex products before explaining custody.
Strong UX is not a replacement for legal clarity.
FAQ
Are shares protected like bank cash?
No. Shares and fund units are generally treated as custody assets, while cash deposits have a different protection framework. Investors should separate the two questions.
Does FINMA supervision remove all broker risk?
No. Supervision is important, but investors still need to understand custody, statements, market access, securities lending and foreign sub-custody.
Should I avoid foreign brokers?
Not automatically. A foreign broker can be appropriate if the investor understands the entity, applicable protection scheme, tax records and operational trade-offs.

Bottom line
Before choosing a broker, separate cash protection from custody-asset segregation. That single distinction makes broker comparisons more serious, more useful and less dependent on app marketing.
