We all know that debt, particularly government debt, is becoming an increasingly worrying problem, especially since interest rates dropped to near-zero in the developed economies of the world. This has led to both developed and advanced economies around the world increasing their total debt levels (i.e. corporate, household and government) as shown on this graphic:
We all know that debt, particularly government debt, is becoming an increasingly worrying problem, especially since interest rates dropped to near-zero in the developed economies of the world. This has led to both developed and advanced economies around the world increasing their total debt levels (i.e. corporate, household and government) as shown on this graphic:
Over the period from 2007
to 2014, government debt has increased from $33 trillion to $58 trillion, an
increase of 9.3 percent on a compounded annual growth rate. In the case
of the United States, the federal debt has risen from $9.2 to its current level
of $19.2 trillion since the beginning of 2008, an
increase of 109 percent over slightly more than 8 years. While this
should be of concern, there is a government indebtedness problem that is even
worse; underfunded and unfunded government pension liabilities. A recent report from Citigroup shows us just how
dangerous the problem has become.
In the past, workers
believed that, once they stopped working at or about age 65, their defined
benefit pension plan would be there to provide for them through to the end of
their lives. In addition to a company or government pension, retired
workers could count on a pay-as-you-go pension scheme like Social Security,
Canada Pension or other state-sponsored pensions. However, given the demographic
shifts which include longer life expectancies and an increase in the number of
retired baby boomers, a significant strain is developing in the state-sponsored pension systems of the world's advanced economies.
Here are some demographic
statistics showing how the population of people 65 years and older are expected
to grow between 2015 and 2050:
Globally - 8 percent in
2015 compared to 15 percent in 2050
Europe - 17 percent in
2015 compared to 26 percent in 2050
China - 12 percent in
2015 compared to 24 percent in 2050
Japan - 26 percent in
2015 compared to 33 percent in 2050
Japan's demographic
problem is the "canary in the coal mine" for the rest of the world.
When a nation has significant growth in the size of its elderly cohort
accompanied by a declining fertility rate, it means that there fewer workers supporting
a greater number of retirees as shown on this graphic which shows the dropping dependency ratio of workers aged 15 to 64 to the number of retirees aged 65
plus over the years between 2015 and 2050:
As the dependency ratio
falls (the ratio of young workers to pensioners), it becomes increasingly
difficult for the economy to support a growing number of pensioners, a
situation that can result in a cut in benefits or a collapse of the pension
system.
We can quite clearly see
the growing problem with an aging population on these two population pyramids where the working age population is highlighted in red:
With that background, let's look at government
pension liabilities. Most of the world's largest governments have pension
plans for their public sector workers and for the general public through
state-sponsored pension plans. While these pension commitments are not
the exactly the same as public debt, they still form a part of a nation's long-term
liabilities. As dependency ratios fall, there is a unsustainable pressure
on future tax payers to fund a growing population of pensioners. Given
the current indebted state of government coffers around the world, this will
create additional pressure on governments with growth in government pension
payments as a proportion of GDP as shown on this graphic:
Here is the estimated
increase in government pension expenditures from 2015 to 2050 as a percentage
of GDP:
As you can see, for some
governments, the dependence on government pension plans will grow significantly
over the period between 2015 and 2050. On average, OECD nations currently
spend an average of 9.5 percent of GDP on public pensions. The combination
of an aging population and a rising ratio of pensioners to workers will push
this up to 12 percent of GDP by 2050 even with the implementation of measures
to limit future pension costs.
Given this information,
there are obviously looming problems with underfunded or unfunded public sector and
state-sponsored social security pension plans. These long-term
commitments are spread over a long period of time and are not treated in the
same fashion as public debt, however, the political consequences of negating on
these social commitments would be difficult. This means that these
liabilities should be treated as "contingent". Here is a chart
showing the contingent government pension liabilities as a percentage of GDP
for OECD nations, divided into public sector and social security pension plans
along with the conventional public debt-to-GDP ratio (grey line):
This is a rather
frightening chart. The average weighted contingent public pension
liability to GDP ratio for the 20 OECD nations is 190 percent of GDP. This
outstrips the average public sovereign debt-to-GDP ratio which comes in at 109
percent of GDP. These same 20 nations have sovereign debts that total $44
trillion; by comparison, the same 20 nations have unfunded or underfunded
government pension liabilities of $78 trillion.
Obviously, this pension funding liability crisis is unsustainable. Governments will have to take steps to
reduce their underfunded and unfunded pension liabilities by taking one or more of these steps:
1.) Increasing retirement
age: While this seems to be the simplest reform, it is the one that is most
fraught with political backlash. Not only is the increase in the number
of years to retirement important, the speed at which this reform is undertaken
is key to meaningful reductions in liability. Using the example of
Portugal, by raising the retirement age by 2 years within the next 10 years,
pension liabilities would be reduced by 5 percent.
2.) Reducing or freezing
retirement benefits: This is easiest to enact when it is put into place for
new, young entrants into the workforce rather than for older workers.
3.) Increasing
pension-specific taxation levels (i.e. increase worker contributions to pension
plans).
4.) Increase the length of working careers by putting incentives into
place that increase the pension
entitlements. This will keep workers contributing to the pension system for
longer.
5.) Improved
administrative efficiencies through central management of public pension
schemes.
From the Citigroup study, we can see that the current government
pension scheme is going to prove to be problematic over the next three decades as the number of baby boomers retirees grows faster than the number of young workers and improvements to health mean that these retirees live far longer than retirees from previous generations. Given the recent and ongoing election cycles in OECD nations, it is interesting to note that there is rarely any serious discussion about the looming public pension plan crisis that dwarfs the size of the public debt.
