Are structured notes safe? Issuer credit risk, explained.
Structured notes are unsecured debt obligations — not deposits, not insured by the FDIC, and not covered by SIPC if the issuer defaults. The issuer's solvency is the backbone of every payment.
What "unsecured creditor" means in plain terms
When you buy a structured note, you are buying a senior, unsecured debt obligation of the issuing bank. Every offering document says so. "Unsecured" means no specific collateral backs your claim — you cannot seize a particular asset if the bank fails. "Senior" means you rank ahead of subordinated debt and equity, but behind secured creditors and priority claims like wages and certain taxes.
In a bankruptcy, unsecured creditors wait for the estate to liquidate assets, file their claims, and receive distributions — often partial, always delayed. Any "principal protection" language in the note is only as good as the issuer's ability to pay at maturity. As FINRA's investor alert states directly: "In the event the issuer goes bankrupt, investors who hold these notes are considered unsecured creditors and might recover little, if anything, of their original investment."
The capital structure: who gets paid first
In a bank holding company bankruptcy, the priority waterfall is roughly:
- Secured creditors (to the value of their collateral)
- Administrative and trustee expenses
- Priority unsecured claims (wages, certain taxes)
- General unsecured creditors — structured note holders sit here
- Subordinated debt
- Preferred equity
- Common equity
Most major US structured notes are issued by a bank holding company or broker-dealer subsidiary, not the FDIC-insured deposit-taking bank itself. That distinction matters: FDIC receivership at the deposit-taking bank gives depositors preferential treatment — but note holders at the holding company level receive none of that protection.
The Lehman Brothers case study
On September 15, 2008, Lehman Brothers Holdings Inc. filed for Chapter 11 — the largest US bankruptcy filing to that point. Lehman had roughly $8 billion or more in face value of US-denominated structured products outstanding at the time of filing, much of it sold to retail investors and marketed as "100% principal protected." (SLCG Economic Consulting, 2009)
On the day of filing, the market value of those notes was effectively zero. Many retail investors learned for the first time that "principal protection" was not backed by collateral or insurance — it was an unsecured promise from an insolvent institution. FINRA later documented that some registered representatives did not understand this themselves and failed to disclose it.
Recovery was partial and spread over more than a decade. The first creditor distributions began in 2012, and the process continued into the mid-2020s. Recovery for general unsecured creditors, including structured note holders, was well below par and followed a years-long liquidation timeline — not the maturity date on their offering documents.
Key lessons
- Principal protection language is only as good as the issuer's solvency — no collateral, no insurance, no government backstop.
- Recovery takes years, not weeks or months.
- Credit risk was escalating — visible in CDS spreads and ratings — for months before the filing. Structured note issuance from Lehman actually accelerated during that period.
- Disclosure failures at the point of sale compounded investor harm.
The safety net question
FDIC, SIPC — and why neither covers issuer default
FDIC insurance
Covers bank deposits — checking, savings, money market deposit accounts, and CDs — up to $250,000 per depositor per institution. Structured notes are securities, not deposits. The FDIC does not insure them, even when the note is sold by an FDIC-member bank. FDIC guidance
SIPC protection
Covers broker-dealer failure — if your brokerage cannot return your assets, SIPC steps in to transfer accounts (including structured notes) to another firm. It provides no protection if the note issuer defaults. A Lehman note held at a surviving brokerage in 2008 had full SIPC custodial protection — and was still worthless because the issuer was bankrupt. SIPC guidance
The structured CD exception
Market-linked certificates of deposit (MLCDs or structured CDs) are actual bank deposits and carry FDIC insurance on principal up to $250,000 per depositor per institution. The trade-off: typically less upside participation and more limited liquidity. Both structured notes and structured CDs still carry market risk — the linked return can be zero if the index doesn't perform.
How to read issuer credit signals
Credit ratings
The three major agencies — Moody's, S&P, and Fitch — each publish long-term issuer credit ratings. Investment grade begins at Baa3/BBB-. Most major US structured note issuers are rated in the A-category, reflecting low but non-zero default probability. The relevant rating for a note investor is the senior unsecured long-term issuer credit rating for the specific entity that is the obligor on the note — typically the holding company.
Critical caveat: ratings can lag market signals. Lehman Brothers carried an investment-grade rating until days before its 2008 bankruptcy filing.
To illustrate recent rating activity: following Moody's downgrade of the US sovereign rating to Aa1 in May 2025, Moody's lowered long-term deposit and senior unsecured ratings at several major US bank holding companies by one notch. These actions do not impair existing structured notes — no acceleration clauses are triggered by rating changes in standard note terms — but they change the credit quality of those issuers for new purchases.
CDS spreads
A credit default swap (CDS) spread is the annualized cost, in basis points, of insuring against an issuer's default on its senior unsecured debt. A 5-year CDS spread of 50 bps means the market prices that protection at 0.50% per year of notional. Spreads move in real time — they often reflect emerging stress before rating agencies act.
Key signals to watch:
- Rapid spread widening (meaningfully wider in days or weeks) suggests market concerns not yet reflected in ratings.
- Spread inversion (short-term spreads exceeding long-term) signals near-term default concerns specifically.
- Spread divergence from peers — if one issuer's spreads widen significantly relative to comparable banks, investigate the cause.
Advisors and managers can access 5-year senior unsecured CDS spreads via Bloomberg (functions CDSW and DRSK) and broker research portals. CDS spreads complement ratings — they do not replace them.
How the wrapper changes the picture
ETF and SMA structures: reducing single-issuer exposure
The ETF wrapper
Exchange-traded defined-outcome (buffer) ETFs — and the autocallable-income ETFs described on the Structured Note ETFs page — pursue structured payoffs through an entirely different legal structure. Instead of holding an unsecured bank note, the fund holds a portfolio of FLEX options that are:
- Listed on a national securities exchange and cleared by the Options Clearing Corporation (OCC) — a federally designated Systemically Important Financial Market Utility under Dodd-Frank
- Held by an independent custodian, segregated from the ETF sponsor's balance sheet under the Investment Company Act of 1940
This structure replaces single-bank issuer credit risk with OCC counterparty risk, which is broadly regarded as much lower given the OCC's SIFMU designation, capitalization requirements, and margin collection practices. The OCC has never defaulted in its history — though this does not mean it cannot.
Multi-issuer SMAs
A structured-note SMA managed across multiple issuers applies classic credit diversification to a note portfolio. Rather than concentrating the full portfolio with one bank, an SMA can spread notional across institutions — JPMorgan, UBS, Morgan Stanley, BNP Paribas, Société Générale, and others — so no single issuer failure impairs the entire portfolio simultaneously.
Institutional SMA mandates commonly specify: an issuer concentration limit (expressed as a percentage of portfolio notional), a minimum acceptable long-term credit rating, and maturity diversification to reduce reinvestment concentration. The specific limits and policies for any given mandate are documented in that mandate's investment policy statement — not stated here.
An SMA manager can also respond to deteriorating credit conditions — declining to reinvest in a downgraded issuer as existing positions mature, or adjusting the issuer mix when CDS spreads signal elevated risk.
| Dimension | Individual Note | Defined-Outcome ETF | Multi-Issuer SMA |
|---|---|---|---|
| Primary obligor | Single bank holding company | OCC (SIFMU-designated) | Multiple banks, diversified |
| FDIC coverage | None | Not applicable | None |
| SIPC (custodial) | Yes — if broker-dealer fails | Yes — assets custodied separately | Yes — if broker-dealer fails |
| Issuer default risk | Full single-bank exposure | Replaced by OCC risk | Diversifiable by mandate |
| Asset segregation | No — commingled with issuer | Yes — 1940 Act custodial | No — individual notes |
| Credit monitoring | Investor/advisor | Structural (OCC) | Active by manager |

Terms
Credit risk glossary
- A creditor with no claim on specific collateral. In a bankruptcy, unsecured creditors are paid after secured creditors and priority claims, from whatever assets remain.
- Ranks ahead of subordinated debt and equity — but behind secured creditors. Most structured notes are senior unsecured obligations of the issuer.
- Credit default swap spread: the annualized cost, in basis points, of insuring against an issuer's default on senior unsecured debt. A real-time market measure of perceived credit risk.
- Rated Baa3/BBB- or above by major rating agencies, indicating relatively low but non-zero default probability. Not a guarantee of survival.
- The central counterparty and guarantor for US exchange-listed options, including the FLEX options held in defined-outcome ETFs. Designated a Systemically Important Financial Market Utility under Dodd-Frank.
- On equal footing. Structured note holders rank pari passu with other general unsecured creditors — they receive no preferential treatment by virtue of the note's market-linked features.
Questions
Credit risk FAQs
No. FDIC insurance covers bank deposits — checking, savings, and CDs. Structured notes are securities (debt obligations registered under the Securities Act), not deposits. The FDIC provides no protection for them, even when the note is sold by an FDIC-member bank.
No. SIPC protects against broker-dealer failure — if your brokerage firm fails, SIPC helps ensure your holdings (including any structured notes) are transferred to another firm or returned to you. It does not protect against the issuer defaulting. If the note issuer goes bankrupt, the note is an impaired or worthless asset regardless of SIPC coverage on the account.
When Lehman Brothers filed for bankruptcy in September 2008, outstanding structured notes — including those marketed as "100% principal protected" — became unsecured bankruptcy claims worth effectively zero on day one. Creditor distributions began in 2012 and continued for over a decade, with recovery rates well below par. The exact figures varied by creditor class and remain subject to compliance review (see compliance note below). The key lesson: any principal protection language is only as good as the issuer's solvency.
An unsecured creditor has no claim on specific collateral. In a bank bankruptcy, secured creditors are paid first (up to the value of their collateral); general unsecured creditors — which is where structured note holders sit — come later, behind administrative expenses and priority claims. This means recovery, if any, is partial and delayed.
A defined-outcome ETF holds exchange-cleared FLEX options whose performance is guaranteed by the Options Clearing Corporation (OCC) — a federally designated Systemically Important Financial Market Utility — rather than an unsecured obligation from a single bank. The 1940 Act custodial structure also segregates fund assets from the sponsor. This eliminates single-bank issuer credit exposure but substitutes OCC counterparty risk, which is broadly regarded as much lower.
Three main signals: (1) credit rating actions from Moody's, S&P, and Fitch — subscribe to alerts for each held issuer; (2) the issuer's 5-year CDS spread, available via Bloomberg or broker research portals — rapid widening relative to peers warrants investigation; (3) regulatory filings (10-K, 10-Q, 8-K) for material capital, earnings, or supervisory developments. These signals complement each other; ratings tend to lag market-based signals like CDS.
