A bond is in default when the issuer breaks any term of the indenture, the contract that governs the bond. That breach can be a missed interest or principal payment, or it can be a violation of a non-monetary promise buried in the covenants. Either kind, once any grace or cure period has expired, gives the trustee legal authority to demand immediate repayment of the entire outstanding balance on behalf of all bondholders.
So the answer to when a bond is in default splits into two paths: payment default and technical default. They look different, they cure differently, but they end in the same place if they aren’t fixed.
Payment Default
A payment default is the direct kind. Interest is due on a set date, or principal is due at maturity, and the money doesn’t arrive. There’s no interpretation involved. The issuer either paid or didn’t.
Most indentures build in a short grace period after a missed payment, commonly around 30 days for interest, giving the issuer time to fix a wire-transfer glitch or a short-term cash shortage before the miss becomes a formal event of default. Grace periods for principal due at maturity are often shorter or nonexistent, because the issuer has known that due date since the bond was first sold. Once the grace window closes without payment, the default is official.
Technical Default
A bond can be in default even when every payment has landed on time. Technical defaults happen when the issuer breaks a non-monetary promise in the indenture. These promises, called covenants, exist to keep the issuer inside financial and operational guardrails that made the bond a reasonable risk to begin with.
Technical defaults tend to surface quietly. An issuer might take on too much additional debt, sell off key assets without permission, or let its financial ratios slip past the thresholds spelled out in the indenture. Checks are still going out, but the conditions underlying the credit have shifted. That’s exactly what covenants are built to catch.
Cure periods for technical defaults run longer than for missed payments. Indentures commonly allow 60 days or more after written notice for the issuer to correct a covenant breach, because diagnosing and fixing an operational or financial problem takes more time than resending a wire. If the issuer can’t fix it inside that window, the technical default hardens into a formal event of default carrying the same consequences as a missed payment.
Which Covenants Trip Issuers Up
Covenants fall into two broad categories. Affirmative covenants require the issuer to do specific things: maintain insurance on pledged collateral, deliver audited financial statements by a set deadline, stay current on taxes, and comply with applicable law. Skipping any required action is a breach. Negative covenants restrict what the issuer can do: take on additional debt beyond a set limit, sell major assets, pay large dividends, or merge without bondholder approval.
Financial maintenance covenants are among the most common triggers for technical default. These set measurable benchmarks, often tested every quarter. A typical one is a maximum leverage ratio (total debt divided by earnings) or a minimum interest coverage ratio (earnings divided by interest expense). When earnings fall or debt rises enough to push the ratio past the contractual line, the issuer is in breach regardless of whether it can still make payments.
Cross-Default Provisions
One covenant that catches investors off guard is the cross-default clause. It ties the bond to the issuer’s other debts. If the issuer defaults on a separate loan or bond issue, that failure automatically triggers a default on the bond containing the cross-default provision, even when every payment on that particular bond is current. The logic: if the issuer can’t honor its obligations to one creditor, the risk to all creditors has increased.
Covenant Waivers and Forbearance
A technical default doesn’t have to end in a formal declaration. When the breach isn’t severe and the issuer’s long-term prospects remain intact, the trustee or a required percentage of bondholders can agree to waive the covenant violation. Waivers are negotiated, sometimes in exchange for a higher interest rate, tighter future covenants, or a one-time fee. Forbearance agreements work similarly: bondholders agree not to enforce their rights for a limited period while the issuer works to fix the underlying problem. These tools keep workable issuers out of proceedings that would hurt both sides.
What Happens After a Default Is Declared
Every detail about how a default is declared and what remedies follow lives in the indenture. For publicly offered bonds, the Trust Indenture Act of 1939 requires the appointment of an independent trustee, usually a large commercial bank or trust company, to represent bondholders collectively. Before a default, the trustee’s role is largely administrative. After one, federal law requires the trustee to exercise the same care and skill a prudent person would use managing their own affairs.1Office of the Law Revision Counsel. 15 USC Chapter 2A, Subchapter III – Trust Indentures The trustee must also notify bondholders of known defaults within 90 days, though for non-payment defaults the trustee’s board can withhold notice if it determines in good faith that doing so is in bondholders’ best interests. No such discretion exists for missed principal or interest payments.2Office of the Law Revision Counsel. 15 USC 77ooo – Duties and Responsibility of the Trustee
Acceleration
The most powerful tool in the indenture is the acceleration clause. It makes the entire remaining principal balance immediately due and payable, collapsing years of future payments into a single demand. Federal regulations governing bond programs recognize this remedy explicitly, listing the declaration of all unpaid principal and interest as an immediate remedy available upon default.3eCFR. 12 CFR 1808.616 – Events of Default and Remedies With Respect to Bonds An issuer that couldn’t make a single interest payment now faces a demand for everything outstanding. That pressure is the point. It forces the issuer to the negotiating table or, failing that, into court.
Restructuring or Bankruptcy
The path after acceleration generally leads to one of two places. In a restructuring, the issuer and bondholders negotiate revised terms: a longer maturity, a lower rate, a partial write-down of principal, or some combination. When restructuring isn’t viable, the issuer files for bankruptcy. A Chapter 11 filing lets the issuer propose a reorganization plan and continue operating while it repays creditors over time.4United States Courts. Chapter 11 – Bankruptcy Basics If the business can’t be saved, Chapter 7 liquidation sells the issuer’s assets and distributes the proceeds to creditors under a strict priority hierarchy.5United States Courts. Chapter 7 Bankruptcy Basics
What Bondholders Recover and What They Can Do
How much bondholders recover after a default depends heavily on where their bond sits in the capital structure. Secured bondholders, whose claims are backed by specific collateral, are first in line. Senior unsecured bondholders come next. Subordinated bondholders recover only after everyone above them has been paid. Equity holders are last and frequently receive nothing.
Historical data from credit rating agencies shows recovery rates for defaulted bonds vary widely. Senior secured bonds have historically recovered the most; subordinated issues often recover far less. Across defaulted high-yield bonds, weighted average recovery rates have ranged roughly from 40 to 60 cents on the dollar in different years, with individual outcomes falling anywhere from near-zero to nearly full recovery.
Once default becomes likely, the bond’s market price drops sharply, often well before any formal declaration. An individual holder faces a real choice: sell at a loss in the secondary market for immediate liquidity, or hold through the process and wait for whatever the trustee can negotiate.
Most indentures also contain a no-action clause that prevents individual bondholders from suing the issuer directly. The right to take legal action belongs to the trustee, acting for all holders collectively. An individual can only proceed if the trustee was asked to act, failed to do so within a reasonable time, and continues to fail. Indentures typically require the trustee to act on written request from holders of at least 25 percent of the outstanding principal, and holders of a majority can direct the trustee on timing and strategy for enforcement.
One right no-action clause can take away: the right to receive payment when due. If the issuer owes you interest or principal on a specific date and doesn’t pay, you have an unconditional right to sue for that specific payment regardless of what the indenture says about collective action for other remedies.
Tax Treatment When a Defaulted Bond Becomes Worthless
When a bond becomes completely worthless, federal tax law treats the loss as if the bond were sold for zero on the last day of the tax year in which it became worthless.6Office of the Law Revision Counsel. 26 USC 165 – Losses The loss is a capital loss, not a bad debt deduction. Held more than one year, it’s long-term; one year or less, it’s short-term.7Internal Revenue Service. Losses (Homes, Stocks, Other Property)
The IRS defines a debt as worthless when surrounding facts and circumstances show there’s no reasonable expectation of repayment.8Internal Revenue Service. Topic No. 453, Bad Debt Deduction You don’t need to wait for every legal proceeding to conclude. If the issuer has entered liquidation and the trustee has indicated recovery for your class of bonds will be zero or negligible, that’s generally enough. The loss is reported on Form 8949, with your cost basis and a sales price of zero.
Timing is where this gets tricky. The deduction has to be claimed in the year the bond actually became worthless. Claim it too early and the IRS can deny it; miss the right year and you forfeit the deduction, though for worthless securities you can file an amended return within seven years rather than the usual three. If there’s any realistic possibility of partial recovery through bankruptcy, the bond isn’t yet worthless for tax purposes even if it’s trading at pennies.
Municipal Bonds Follow a Different Path
The framework above tracks corporate bond defaults. Municipal bonds work differently in one important respect: municipal issuers can’t file for Chapter 7 liquidation because you can’t sell off a city. Distressed municipalities use Chapter 9 of the Bankruptcy Code, which allows for debt adjustment while the government continues to operate. Municipal defaults also concentrate in specific sectors, with housing revenue, healthcare facility, and industrial development bonds carrying meaningfully higher default risk than general obligation bonds backed by taxing authority. Recovery timelines can stretch for years, and the legal protections available vary significantly by state and by the type of obligation.
