Sovereign Default

A sovereign default is a government's failure to repay its debt on time, which can lock it out of markets, crash its currency and force restructuring.

When a country cannot service its bonds, it defaults, as Sri Lanka did in 2022 and Argentina has repeatedly. Default usually triggers a currency collapse, IMF involvement and painful restructuring with creditors.

Countries that borrow in foreign currency are most at risk, since they cannot print dollars to repay. India borrows mostly in rupees domestically and holds strong reserves, keeping its sovereign credit rating investment-grade and default risk low, but rating outlooks still matter for borrowing costs.
