The IIF, which represents global banks and financial institutions, said the first-quarter debt-to-GDP ratio jumped by over 10 percentage points, the largest quarterly surge on record, to reach a record 331 per cent.
While the rise in debt levels was well below average quarterly gains seen from 2015 to 2019, the pace of global debt build-up by governments, companies, financial institutions and households had accelerated since March, it said.
Overall gross debt issuance hit an "eye-watering" record of $12.5 trillion in the second quarter, compared with a quarterly average of $5.5 trillion in 2019, the IIF said. It noted that 60 per cent of those issues came from governments.
