Some investors buy distressed government debt cheaply, then pursue repayment through courts.

How a Defaulted Bond Becomes a Legal Claim

When a government cannot keep up with its bond payments, it may offer creditors a restructuring: exchange old bonds for new ones with lower payments, later due dates, or both. Most creditors may accept because recovering part of the debt can be better than waiting indefinitely. But a bondholder that refuses the deal can try to enforce the original contract in court. Unlike a company, a country generally cannot be put through a single bankruptcy process that forces every creditor into the same settlement.

That gap creates an opportunity for distressed-debt investors. They buy bonds after a default, when their market price has fallen far below the amount promised, then seek payment under the original terms. A successful claim can be worth much more than the purchase price, although litigation is costly and repayment is never guaranteed. Critics call some such investors “vulture funds” because they profit from debt acquired during a country’s crisis.

Why Argentina’s Ship Was Detained

Argentina’s 2001 default led to major bond exchanges, but some creditors rejected the offers. One was NML Capital, which pursued Argentina in court over bonds it had bought at a steep discount. In 2012, a Ghanaian court detained the ARA Libertad, an Argentine naval training ship, at the request of NML’s legal effort to secure leverage for its claim.

The ship was not simply treated like a government-owned asset available to any creditor. Argentina argued that a warship was protected by sovereign immunity—the principle that one country’s courts generally cannot seize another country’s military property. An international tribunal ordered Ghana to release the vessel, and it returned to Argentina.

The Bigger Leverage—and Its Limits

The ship episode showed how a creditor can use assets abroad to pressure a government, but it did not itself settle the bond dispute. Argentina’s broader fight turned on court rulings about how it could pay creditors that had accepted restructurings while continuing to resist the holdouts. The episode’s lasting lesson is that sovereign debt has no ordinary bankruptcy referee: negotiations, contract terms, national courts, and immunity rules can all determine who gets paid—and how much leverage a creditor can apply along the way.
