An international economic consultant is warning that Barbados and other Caribbean countries are at the tipping point of a serious debt crisis.“There is now a growing sense that the world needs another new global initiative on debt,” said Jwala Rambarran, a former Governor of the Central Bank of Trinidad and Tobago.His sobering declaration was made yesterday during the virtual launch of a report entitled: Caribbean Emancipation 2030: A Sovereign Debt and Climate Justice Initiative for Caribbean Small Island Developing States (SIDS).Rambarran, who authored the study on behalf of the Caribbean Policy Development Centre (CPDC) contended that there’s now a need for a fresh solution to address this state of affairs.One chart in the findings of the study placed Barbados in a red zone as the Caribbean country with the highest gross public debt of 157 per cent of Gross Domestic Product (GDP) in 2020.
