Inspired by the Bank of International Settlements, we have put together some traffic lights for debt indicators across the major economies. There are two components:


  1. the amount of debt (or the debt burden) and,
  2. the cost of debt (or the debt service ratio)


The focus here is on the non-financial private sector: the aggregate of household and non-financial corporate debt.


Where debt is rising rapidly as a share of GDP, we should be concerned. Where the cost of servicing debt is rising rapidly as a share of GDP, we should also be concerned.

Stop or go? A green light in developed economies ...


There are few concerns in developed economies. The private sector has used the last few years to steadily deleverage. That process has been assisted by government policy whereby interest rates have been kept ultra-low and debt has (selectively) been transferred from the private sector to public sector balance sheet.


... but red lights across emerging markets


Here the story is much more concerning. Almost wherever we look (with the notable exception of India), debt burdens have spiralled higher and debt service ratios are rising rapidly. There is a significant publication lag in this data, but the recent news from China (in particular) suggests that the problem is getting worse, not better, since the turn of the year.


Timing the next debt crisis is extraordinarily difficult, but we have a very good idea where to be looking.
