ETFs, ETCs, ETNs and ETPs: bought the same way, different rights

The misleading similarity

An investor looks up an ISIN, sees a price, places an order and finds the product in their securities account. Operationally, an equity ETF, a gold ETC and a crypto ETP can look like variations of the same object.

They are not necessarily.

A listing describes how an instrument is traded. On its own, it does not say what the instrument legally is. Two products traded on the same exchange can grant very different rights: in one case a share of a collective investment scheme; in another a claim on an issuing company, backed — or not — by assets pledged as security.

It is the first distinction to learn, because it precedes all the others. TER, performance, spreads and liquidity matter, but they do not replace the fundamental question: what do I own, and whose solvency does my claim depend on?

ETP: umbrella word or product category?

In the international literature, exchange-traded product is often used as a general term for exchange-traded instruments offering financial exposure. In this broad sense, ETFs, ETCs and ETNs all belong to the ETP family.

In commercial practice and in databases, however, the labels are not uniform. Some issuers use “ETP” as the name of the individual product, especially in the crypto segment. Other venues or data providers adopt different taxonomies. The acronym alone is not enough to reconstruct the legal structure.

Rebalix preserves this ambiguity rather than hiding it. In its screener, ETP is a residual category, not the umbrella word for the whole universe. When it needs to separate these products from fund-ETFs, Rebalix considers the three labels ETC, ETP and ETN together, without turning them into a new commercial category.

As of the 7 September 2026 snapshot, the live Rebalix registry contains 61 products classified as ETPs: 58 attributed to the 21Shares platform and three Bitcoin ETPs from other issuers. One of the 61, Sygnum Platform Winners, does not pass the engine’s minimum-fields gate; that is why the public screener shows 60. What actually backs each product — which collateral, which claim — cannot be read from the theme in its name: it is read in the documents, and that is the point of this chapter. In the same census there is no ETN at all, whether by declared type or by name.

These figures describe the Rebalix perimeter as of the stated date. They are not a universal definition of the European market.

ETF: a share of a fund

ETF stands for exchange-traded fund: the decisive word is fund.

In the European Union, most ETFs aimed at retail investors are set up as UCITS — collective investment schemes governed by the common European framework. The capital raised is invested according to the fund’s policy, and the investor owns shares or units of the sub-fund, not a bond issued by the management company.

The UCITS Directive defines the common European framework for these schemes. The concrete form can vary: contractual fund, investment company, SICAV or ICAV, depending on the domicile. What matters is that the investor participates in a collective pool of assets subject to the rules that apply to the fund.

An example from the Rebalix census makes the point. Franklin Templeton ICAV is an Irish umbrella vehicle with segregated liability between sub-funds. Whoever buys a class of one of its ETFs holds a participation in that sub-fund. They are not lending money to Franklin Templeton, and repayment does not depend on the management company’s creditworthiness, as it would with an ordinary debt note.

This does not make the ETF risk-free. The value of the investments can fall; market, liquidity, counterparty, custody and replication risks can exist. Ring-fencing does not protect against losses generated by the underlying. It protects against a misunderstanding: the fund’s assets are not the assets of the company that manages it.

ETC: often a debt security, not a fund

ETC commonly stands for exchange-traded commodity. In Europe it is used to gain exposure to a single commodity — gold, for example — or to commodity baskets and indices that a UCITS could not necessarily hold in the same form.

Many European ETCs are not funds. They are debt securities issued by a vehicle, with a return linked to the price of the underlying. Investor protection therefore depends on the issue’s documentation: assets pledged as security, their location, the custodian, creditor priority, enforcement mechanics and limited-recourse clauses.

The physical gold case

The Xtrackers Physical Gold ETC prospectus describes debt securities that do not take the form of a fund or collective investment scheme. The issuer is DB ETC plc, a Jersey special-purpose vehicle. The notes are secured and limited recourse: they are backed by the assets pledged to the specific issue, but holders’ recourse is limited to those assets. If they were not enough, the documents do not automatically grant the right to pursue the rest of the issuer’s estate.

The underlying is allocated metal, held through the custody structure and subject to the security interests provided by the programme. “Physical”, however, does not mean each investor personally owns an identified bar in their account. It means the mechanism of the security is supported by metal and by a chain of legal rights described in the prospectus.

Not even vault gold removes every operational risk. The prospectus also contemplates the insolvency of the custodian or of a sub-custodian. The asset is physical; the investor’s right remains governed by contracts, security interests and insolvency procedures.

When “physical” does not mean an asset in a vault

Xtrackers Physical Carbon EUA ETC is an even more instructive case. Here too the investor buys a secured, limited recourse debt security, not a fund share. But the economic underlying is linked to European emission allowances (EUAs). The product is present in the Rebalix registry, but as of the snapshot date it does not appear in the public screener because it does not pass the minimum-fields gate.

The structure is not a box full of physical objects. Its value rests on rights relating to the allowances and on the performance of the counterparty provided for in the structure. The prospectus expressly exposes the investor to the execution and insolvency risk of the Carbon Counterparty as well.

The lesson is general: words like “physical”, “backed” or “collateralised” must be read together with the nature of the collateral and the rights linking that collateral to the holder of the security.

ETN: the issuer’s promise

ETN stands for exchange-traded note. Strictly speaking, it is a debt note whose repayment is linked to the performance of an index or another exposure, net of costs and according to the stated formula.

An ETN can track its index very well and, at the same time, expose the investor to the issuer’s solvency. If the note is unsecured, there is no segregated pool of securities or specific collateral the holder can rely on. The investor is a creditor of the issuer, ranking as provided.

That is why it is not correct to define ETCs and ETNs generically as “debt instruments guaranteed by the underlying”. Some ETCs and ETPs are collateralised; an ETN can be unsecured debt. Even where collateral exists, you need to understand what it covers and which risks remain.

In the Rebalix census there are zero ETNs. The public screener therefore shows no ETN category, and there is no Rebalix example to use without forcing reality. In this guide the ETN remains a category you need in order to understand the market — but an openly theoretical one relative to the current registry.

Crypto ETPs: collateralised does not mean free of issuer risk

The 21Shares Ethereum Core Staking ETP lets us observe a different structure. It is issued by 21Shares AG and declares Ethereum as collateral; the documentation describes segregated custody accounts and the risks connected to the custodian and to the counterparties involved in staking.

The most important point is in the issue’s own documentation: collateralisation does not automatically cancel the effect of the issuer’s creditworthiness on the market value and on the outcome of an insolvency.

It is a distinction many simplified explanations lose. Collateral can reduce or transform credit risk, but it does not authorise writing “zero issuer risk”. At a minimum you should assess:

• ownership of the assets;
• segregation from the custodian’s and issuer’s own assets;
• holders’ security interests;
• the collateral’s valuation and rebalancing rules;
• the operational counterparties;
• the time and cost of a possible enforcement;
• the limited-recourse clauses.

With a staking product there is one more layer: part of the economics depends on the processes, counterparties and risks of the staking activity itself. Knowing which crypto-asset appears in the name is not enough.

A useful — not sufficient — table

The seven questions to ask before buying

The ticker and the commercial name are not enough. Before buying an ETC, an ETP or an ETN, it is worth answering seven questions:

1. 1
   Is it a fund or a debt security?

   Look for the legal designation in the prospectus; do not infer it from the commercial suffix.
2. 2
   Who is the issuer?

   A management company, a fund, a bank and a special-purpose vehicle are not the same thing.
3. 3
   Is the product secured or unsecured?

   “Collateralised” must be documented.
4. 4
   What is the collateral?

   Equities, allocated metal, cash, securities, crypto-assets or contractual rights carry different risks.
5. 5
   Who holds or controls the assets?

   Custodian, sub-custodian and counterparty are part of the structure.
6. 6
   What does limited recourse mean?

   If the dedicated assets are not enough, the holder may have no claim on the rest of the issuer’s estate.
7. 7
   What happens in an insolvency?

   The answer must come from the prospectus and the legal documents, not from a marketing description.

How Rebalix classifies

The Rebalix classification is built in two steps.

In the registry, the readers assign the product type according to per-issuer rules: data declared by the issuer’s site or feed when available, platform rules for 21Shares, and a name-based override for the iShares ETCs that the original feed treats as funds.

The engine then normalises the field used by the screener. It keeps the ETC, ETP and ETN values; in the other cases it checks the name and, absent any structural indication, uses ETF as the default value.

Neither FIRDS nor CFI codes are used for this classification, and there is no product-by-product manual correction. The method makes the census repeatable, but it has an explicit limit: legal form, collateralisation, recourse and custody are not yet queryable columns of the database. That information comes from reading the prospectuses.

This is why Rebalix always distinguishes between what the data can prove and what requires reading the documents. The first records of the future “ETC/ETP structure fields” project are precisely the cases used in this chapter.
