Barbados' new bond - finalised in a deal with bankers on Wednesday - is likely to leave an even bigger imprint, especially with smaller, tourism-dependent countries that were pushed to the brink of economic collapse during the COVID-19 pandemic.
"And hence we would not be facing the kind of debt crises that many countries are about to face".
Credit Suisse banker Ramzi Issa, who led on some of the key financing aspects on the bond deal which involved a buyback, said it was "hugely significant".
"It is like a dose of vaccine for your debt," said Sui-Jim Ho, a partner at Cleary Gottlieb - the law firm that helped craft the clause for Barbados.
The bond deal has an ecological feature too.
