Exchange-Traded Note
Also known as: ETN, Exchange-traded certificate
Tracks an index like an ETF, but it is a bank's promise rather than a pot of assets — and the difference only shows up on the day the bank fails.
1 · SnapshotThe one idea to remember
2 · BeginnerWhat is it, really?
An exchange-traded note tracks an index. You buy it and sell it on an exchange, just like a share. So far this sounds like an ETF.
The difference is what sits behind it. An ETF owns the things in the index. Buy an ETF and you own a slice of a real pot of shares or bonds. An ETN owns nothing. It is a written promise by a bank to pay you what the index did.
That promise is worth exactly as much as the bank behind it. If the bank fails, the index can be up and you can still lose your money. You are a lender to that bank, standing in the same queue as everyone else it owes.

Which risks decide the outcome
Not how risky this is, and not a rating — there is deliberately no total. It says which of five failure modes drives what happens here, in the same order on all 129 products so they can be compared. This publication's own reading; see the notice below.

What decides it here. It tracks an index and it is an unsecured claim on one bank. The index is what you watch and the issuer is what decides the outcome — which is the whole difference from the fund it is mistaken for.
3 · IntermediateHow it works in practice
Why the wrapper exists at all
- It can track anything. A promise is easy to write. Indices that are hard or illegal to hold directly — some commodity, volatility and emerging-market exposures — are simple to promise.
- No tracking error by construction. The issuer owes the index return less a stated fee. There is no basket to rebalance and no dividend to reinvest imperfectly, so the note does not drift from the index the way a physically replicating fund can.
- Tax and structure. In some jurisdictions the note's treatment differs from a fund's, which is a large part of why the wrapper survives.
What you are actually holding
A senior unsecured claim on the issuer, with a payoff formula attached. Everything an unsecured bank bondholder worries about applies: the issuer's credit spread, its capital position and, in a resolution, whether the note is bail-in-able.
Three failure modes that are not the index
- Issuer default. The one everybody names and nobody prices until it happens.
- Issuance suspension. If the issuer stops creating new notes, the listed price can detach from the index and trade at a large premium — the arbitrage that normally holds them together has been switched off.
- Early redemption. Most notes let the issuer call them. A position can be closed at the issuer's convenience rather than yours.

Pricing decomposition
The theoretical value is the index leg discounted at the issuer's own curve rather than the risk-free one:
What the symbols mean
- Va value
- Ean expected value
- Tmaturity, in years
- Nthe normal distribution, or a count
- rthe interest rate, per year
where \(s_{iss}\) is the issuer's credit spread. Two notes on the same index from different issuers are not the same instrument, and the spread difference is the price of that fact — usually invisible, because it is charged as a fee rather than quoted as a spread.
The arbitrage that holds the price together, and how it breaks
Authorised participants keep the listed price near the indicative value by creating and redeeming at par. That mechanism is contractual, not structural: the issuer may cap or suspend creations, typically when its own hedging capacity or balance-sheet limits bind. The moment it does, the note becomes a closed-end instrument, and the premium is bounded only by what buyers will pay.
Reading the term sheet
Three clauses decide the risk: the issuer call, the acceleration event (often an index level, which converts a market fall into an immediate termination) and the fee accrual, which is frequently daily on notional and therefore path-dependent in a way the headline percentage does not convey.
The formulas above are standard textbook formulations, simplified for teaching. They explain the mechanism — they are not a valuation tool, and they will not reproduce a dealer’s price.

Now say it back
Close the page and give Exchange-Traded Note in four sentences. It takes a minute and it is the only way to find out whether reading it was enough.
- Who wants what — two parties wanted opposite things badly enough to write it down.
- What the contract obliges, and when — not the payoff; the obligation.
- Where the money comes from — name the source, or you have described a hope.
- What makes it lose — the ordinary way, not the dramatic one.
