BRIDGETOWN, Barbados - STANDARD & POOR’S (S&P) HAS REVISED Barbados economic outlook to negative from stable, while the agency is keeping the ‘BB+/B’ credit rating it assigned the country last year. In a release yesterday, S&P analyst Richard Francis said Barbados had slipped back into recession after a weak recovery between 2010 and 2012. But Francis warned that unless the country made quick adjustments to narrow the widening deficit, the country could face another downgrade.
