“Many advanced economies will be threatened by another, long-term fiscal shock unless they tackle the problem of ageing populations, the ratings agency Fitch warned on Monday. In particular Cyprus, Ireland and Japan, could well see the cost of ageing populations jump over the next decade, the agency said, warning that this would affect the sovereign debt ratings of such countries at some point. ‘Luxembourg, Belgium, Malta and Slovenia face the most severe impact over the very long term,’ Fitch noted.”
