The global debt-to-GDP ratio hit an all-time high of 322% in the third quarter of last year, according to a report released Monday by the Institute of International Finance.

Debt rose by almost US$10 trillion to US$252.6 trillion from a year earlier, said the Washington-based IIF, which is comprised of the world’s leading financial institutions. Debt from all sectors — ranging from household to government to corporate bonds — surged.
