Malaysia’s
household debt (% of GDP) from 2002 to 2016 was as follows:
According
to the IMF, although finance is generally believed to contribute to long-term
economic growth, “recent studies have shown that the growth benefits start
declining when aggregate leverage is high”. From experience and past crises,
increases in private sector credit, including household debt, may raise the
likelihood of a financial crisis and could lead to lower growth. In 2016, on
average the household debt to GDP ratio reached 63% in advanced economies and
21% in emerging market economies.
Globally,
household debt has continued to grow in the past decade. The IMF had a sample
of 80 advanced and emerging market economies to study the relationship between
debt, growth and stability.
Findings
show there is a trade-off between the short-term benefits of rising household
debt to growth and its medium-term costs to macroeconomic and financial
stability. In the short term, an increase in the household debt-to-GDP ratio is
typically associated with higher economic growth and lower unemployment, but
the effects are reversed in three to five years. Moreover, higher growth
in household debt is associated with a greater probability of banking crisis. These
adverse effects are stronger when household debt is higher and become more
pronounced for advanced than for emerging market economies.
The
impact of household debt on financial stability from a balance sheet and cash
flow point of view was examined by IMF staff. The result of which is shown
below:
Figure 1 –
First and second round effects of the build-up of household debts on financial
stability
Note
The above figure depicts the
interactions between household debt, the financial sector, and the real economy.
The balance sheet view (panel 1) shows assets and liabilities (debt) at the
household level, whereas the cash flow view (panel 2) shows household income and
expenses in the form of consumption and debt service. The two main channels
through which household debt and consumption interact are deleveraging and debt
overhang. Debt overhang may adversely affect aggregate demand through
deleveraging or a crowding out of consumption by the debt service burden.
Deleveraging can occur through forced or accelerated repayment of debt,
reduction in new credit, and increased defaults or personal bankruptcies. From
a legal standpoint, default follows from a situation in which assets and income
are insufficient to cover debt-servicing costs, and bankruptcy from lack of
sufficient assets and income to repay the debt. There may be second-round
effects, such as Fisher-type debt-deflation dynamics, that may be caused by
downward asset price spirals.
However, country characteristics and institutions
can mitigate the risks associated with rising household debt. Even in countries
where household debt is high, the growth-stability trade-off can be
significantly mitigated through a combination of sound institutions, regulations,
and policies. With better financial regulation and supervision, less dependence
on external financing, flexible exchange rates and lower income inequality may
reduce the impact of rising household debt on risks to growth.
The IMF concludes that overall, policymakers should
carefully balance the benefits and risks of household debt over various time
horizons while harnessing the benefits of financial inclusion and development.
