The default traps in sovereign borrowing refers to the idea that once a country falls into a default, it is more likely to default again in the future, compared to another country with identical future output ability. The idea of default traps is related with the asymmetric information between the borrower and the lender about the expectation of borrower's future output (GDP), the negative output shocks that increase the borrower's future default probability and other possible factors like political shocks.
