"I predict that the next 10 years will be the Decade of Debt.
It will not end well," Laffer, who is President at investment and wealth advisory Laffer Tengler Investments, told CNBC.
As a share of the global gross domestic product, debt has risen to 336%.
This compares to an average debt-to-GDP ratio of 110% in 2012 for advanced economies, and 35% for emerging economies.
It was 334% in the fourth quarter of 2022, according to the most recent global debt monitor report by the Institute of International Finance.
