Fitch warns bond yield surge is worsening debt outlook for developed economies

LONDON, Oct 13 (Reuters) — Rising government bond yields are making it much harder for major developed economies to stabilise debt burdens, with countries including France, the US and Britain facing growing fiscal challenges, credit rating agency Fitch said on Tuesday. In a report, Fitch said benchmark 10-year government bond yields in the world's 10 largest developed economies had risen by an average of 81 basis points so far this year. That would contribute to a nearly $4 trillion increase in overall developed-market government debt, taking it above $75 trillion, or $68.5 trillion across the top 10 economies. The median 10-year yield across the largest developed economies is now 161 bps above the average interest rate paid on outstanding debt, making it harder to reduce or even stabilise debt levels France faces one of the steepest challenges. It would need to cut its primary deficit to 0.4% of GDP from a projected 2.9% this year to stabilise its debt burden, while a rise in effective borrowing costs to current market yields would require a further fiscal adjustment of about 3.1% of GDP The US is expected to run the largest general government budget deficit this year, at 7.5% of
