The next global economic slowdown could come from rising risks outside the banking sector, according to the International Monetary Fund.

Leverage in the nonfinancial sector for G-20 economies as a whole has surpassed its precrisis high, the IMF said Wednesday in its Global Financial Stability Report.

Nonfinancial sector debt refers to borrowing by governments, nonfinancial companies and households. The total level of that debt for G-20 economies rose to $135 trillion, or about 235 percent of aggregate gross domestic product in 2016, surpassing the debt-to-GDP ratio of 210 percent in 2006, before the financial crisis, according to the IMF.
