What actually happens when a country defaults on its debt

A sovereign default happens when a government misses a scheduled payment, whether interest or principal, on its debt. There's usually a grace period, often 30 days, before the missed payment is formally classified as a default by rating agencies and triggers contractual consequences for bondholders.

The immediate legal effect is narrower than the word "default" suggests: it doesn't erase the debt or automatically restructure it. It typically triggers cross-default clauses in the country's other debt agreements, meaning many of its other loans become technically due immediately, even if those specific payments weren't missed.

What follows is usually a negotiation, not a collapse — bondholders and the government negotiate a restructuring, often extending maturities or reducing the amount owed, sometimes over months or years. Argentina's 2001 default took roughly 15 years to fully resolve through the courts; other cases have resolved in under a year.
