NZZ on life tables

Influential Swiss daily Neue Zürcher Zeitung has quoted me on the subject of the appropriate choice of mortality tables for Swiss pension funds (here and here, both in German). Most Swiss pension funds still use period life tables rather than the more realistic cohort life tables (for a distinction see here - nothing useful on Wikipedia, but a nice Wolfram demo here). Cohort tables are preferable because they better reflect increased longevity, whereas period tables have to be adjusted manually. Given that longevity continues to improve, the use of period tables will give systematic advantage to the present pensioner cohort at the disadvantage of future cohorts.

The recently published "technical basis" BVG2010 makes available a set of cohort life tables for the first time. It would make sense for pension funds to adopt that new basis as soon as possible, despite the consequential nominal increase of their liabilities.

This time may truly be different

Here is a fascinating account of the impact of ageing on the balance sheet adjustment that much of the private sector is beginning to go through by the Deputy Governor of the Bank of Japan, Kiyohiko Nishimura. He claims that this balance sheet adjustment (aka de-leveraging) is unprecedented and qualitatively different from earlier episodes as it hits mature, ageing populations rather than growing, young ones. He demonstrates impressively how the downturn of the inverse dependency ratio coïncided with the busting of the property bubbles in Japan, the US, Greece, Portugal and Spain. He also addresses the ineffectiveness of monetary policy transmission mechanisms in that environment, obviously from the pioneer vantage point of Japan.

If this is confirmed, it may well be that we are at the early stages of a renaissance of a quasi-physiocratic movement. The thought is certainly fascinatingly plausible that the baby boomer bulge moving through the demographic "pyramid" has a strong (leveraged?) impact on housing prices: inflationary in the acquisition phase and deflationary during disposition. The impact reverberates into the highly leveraged banking sector via the mortgage leverage linkage.

The demographic shift is well documented for most mature economies. Another important driver that has more aspects of a zero-sum game may be that of migration: Anecdotal evidence for the small Swiss market shows a strong influx of well-paid foreigners into Switzerland in the recent past. This may be an important contributor to the upswing in the Swiss real estate market that the SNB is beginning to sound the alarm about. It probably compensates some, if not all of the ageing impact in this particular market. So I wonder whether central banks also watch migration.

Interestingly, the correlation between real asset prices and ageing populations was confirmed in an earlier BIS working paper, although the author was very cautious about his conclusions. The time series he analysed was much shorter (1970 - 2009), and he did not look at it from the perspective of the ongoing balance sheet adjustment. But as per Mr. Nishimura's view, that combination may indeed lead to "the distinct possibility that this time may truly be different."

Hedge accounting does not account for longevity hedges

Tuesday's ARG meeting was extraordinarily interesting, for it held a good and a bad surprise: Meeting the incoming IASB Chairman Hans Hoogervorst was a pleasant surprise, while discovering that the hedge accounting project underway will actually discourage longevity hedging if the standard were to stand as it currently does. This is a consequence of the proposed architecture of pensions accounting. Hence there appears to be no easy way out.

However, this outcome is deeply unsatisfactory and should be addressed. While there are not very many cases to account for at present, it would be unfortunate indeed if effective management techniques for the second most important risk facing pension funds were developed, only to be thwarted by accounting artefacts. Watch this space!

More indices - insurance linked

This copy of Sigma has been sitting around for way too without being mentioned here: The role of indices in transferring insurance risks to the capital markets. It's such a comprehensive overview of insurance linked securities (ILS) that I wanted to do an in-depth review, but never got round to it. Given that this market segment links two very relevant marketplaces (capital markets and reinsurance), its growth from 4% of catastrophe reinsurance capacity 5 years ago to 12% of capacity now is substantive. However, Sigma does not answer the #1 question that concerns me as an investor: how do I know whether the premium I get for taking the risk in question is fair, assuming that the issuer will only approach the ILS market if he thinks that he can get a better deal there than in the conventional reinsurance market? How is the reinsurance market in any specific segment priced? There seems to be a significant amount of information asymmetry there.

Longevity indices

Here's a useful and interesting paper on Longevity Indices and Pension Fund Risk. The abstract sums it up nicely:

Pension fund longevity risk is becoming increasingly important. Longevity indices would allow the creation of liquid derivatives that could be used to hedge this risk. However, there are a number of criteria that such indices would need to fulfil to provide an optimal solution, as well as a number of forms that the derivatives could take. These features are discussed, together with the characteristics of some existing longevity indices.

Longevity indices look like a viable risk management instrument, but given their utility bounded by liquidity and granularity, they are anything but trivial to design. Add to the mix an extremely fragmented market like the Swiss with its many small IORPs and their high volatility risk. Longevity risk also comprises level risk, trend risk and catastrophe risk. Interestingly, catastrophe risk is only seen as a one-off surge in mortality rates: "similar one-off falls in mortality rates do not occur." Black swans, anyone?

EU Green Paper

The Commission has published its impatiently expected Green Paper towards adequate, sustainable and safe European pension systems today. The scope of the paper is very broad indeed, questioning the basics of the current EU pension legislation except - ostensibly - member states' responsibility for pensions. While initial reactions focus on incumbent battlefields such as solvency regimes for pension funds and retirement age, I would not be surprised at all if the intended discussion were soon to turn towards more comprehensive harmonisation, especially given the objective of adequate and sustainable pensions in the light of most member states' evident inability so far to reform their pensions systems sufficiently to rise to the double challenge of demographic shifts and inevitable fiscal austerity.

EFRP has started its own EU Pensions Debate website. It will be interesting to monitor the yield of the four month consultation period.

Linking pensions to longevity

The OECD has issued an interesting working paper Life-Expectancy Risk and Pensions: Who Bears the Burden?, which looks into a number of OECD countries' relatively recent policy changes to share part of the longevity risk with pensioners. Given the proportions of the risk and the massive inter-generational skew in cost/benefit, this is perfectly reasonable and should be adopted universally.

For some undisclosed reason, Switzerland is virtually omitted from the scope of the analysis, even though there clearly is no linkage between longevity risk and pensions whatsoever. In the Swiss three pillar system, longevity risk is borne in the first pillar by the tax payer, by employers in the second, and by individuals in the third pillar.

Victims IV: The real crisis

The Economist deserves praise for having featured a special report on the impact of ageing populations in this time of crisis, which overrides longer term requirements with its fiscal profligacy. The majority of industrialised countries were already on an unsustainable fiscal path before the crisis struck. It is difficult to see how government finances will ever be able to return to a trajectory that is stable longer-term.

It goes without saying that the foreseeable instability of public finances has a dramatic impact on capital funded retirement systems. At this juncture, the jury is still out on the prefix of instability, i.e. whether we will see inflation or deflation. Either way, the contradictory demands on the investment strategy of individual funds are anything but trivial and may need to be implemented consistently in very short order once the dust settles. Scenario analysis and preparation is the name of the game. I look forward to a workshop producing a Shell/Oxford-method scenario analysis on Switzerland 2030, to which I have been invited by the federal crisis management education unit.

Impact of accounting and prudential regulation on pensions

"A long-term view involves short-term risk, whereas a short-sighted strategy involves increased risk over the long term."

EDHEC just released its impressive report Impact of Regulation on the ALM of European Pension Funds. Even though we disagree in some instances, we think this is mandatory reading for anyone in the pensions investment space because it highlights those areas of regulation which will be of increasing consequence for pension funds' investment strategies in the near future, as we have continued to stress over the recent past.

At the core of the report is the development of an asset allocation model in the presence of liability constraints. The solution involves the components cash, risky assets and the liability hedging portfolio. The state of the art model takes inflation and longevity risk management into account as well.

There is not enough space nor time for an in-depth review of this valuable piece. Nevertheless, I would like to mention two issues that have slightly moderated my enthusiasm for the report:

• There seem to be a few at least implicit factual inaccuracies in the parts describing the regulatory environment. The most glaring of which may be the assumption that the EU pensions directive is applicable in Switzerland - it is not.
• Accounting standards seem to be understood to effectively determine investment action. While it is not unheard of that managements structure transactions in such ways as to optimise their reporting, this clearly goes one step too far. We are well aware of the interdependence between perception (qua accounting standards) and (economic) reality, but at least in an academic report, the latter needs to retain some vestige of predominance over the former. Remember: pension funds' long-term time horizon, as accounting standards can and do change.

Longevity in Switzerland

It is hardly a coincidence that the Federal Office of Statistics publishes a new study about the Future of Longevity in Switzerland (German, French) today. There is an upcoming referendum to decide about the proposed reduction of the transformation rate with which accumulated pensions capital will be transformed into annuities. Longevity expectations are an important factor in that hotly contended issue. The study expects an additional 5 to 9 years of life expectancy gains over the next 20 years with a continuation of morbidity compression. 

The tyranny of the present

In a recent issue of its flagship publication Sigma, SwissRe described Scenario analysis in insurance, identifying scenario analysis as a key tool to analyse fat-tail risks and their impact on profitability and competitive position of insurers. One of the pioneering sources of scenario analysis is the approach developed by Shell. Whereas scenario analysis is referred to as a key tool for both strategic planning as well as enterprise risk management of insurance, Sigma reports with some degree of astonishment that banks do not use it to assess their total enterprise risk exposure.

Applying the concept of scenario analysis to pension funds should be self-evident, not least if you think of a pension fund as the insurance subsidiary of your firm. It faces a set of opportunities, threats and parameters quite similar to those of an insurance, yet scenario analysis is not common in the pensions industry. Nevertheless, a number of pensions-specific scenarios easily come to mind: a jump in longevity due to unexpected medical progress, prolonged negative real interest rates, a pandemic (as explained in Sigma), regulatory changes to the competitive landscape ...

The Economist Intelligence Unit has just come up with its own bleak exercise in scenario analysis (hat tip Global Guerrillas). Its central forecast of stabilisation is assigned a probability of just 60%, whereas the more disruptive instability scenarios are assigned 30% (de-globalisation) and 10% (collapse in USD) respectively. Scenario analysis has been posted as a means to escape the tyranny of the present, but being where we are today, we are not so sure this is a good thing.

Mortality-linked securities

The Pensions Institute has an excellent new paper on Mortality linked Securities and Derivatives. The paper describes the problem (longevity risk) and what conclusions can be drawn from present experience in pensions buyouts and securitisation transactions. They also discuss the pricing of longevity risk in the absence of a liquid mortality-linked capital market. For a complete picture, we'd be interested in the fallout of the present turmoil in the asset-backet securities and credit derivatives space on mortality-linked securities ...  

Redefining Old

Nomura has an excellent piece of research out that goes well beyond what that genre usually entails in the brokerage space. The Business of Ageing is an extensive discussion of the key risk of the pensions industry that is longevity, its implications for the real economy, financial markets and the major industries. I particularly value the section about longevity with its discussion of the technophysio approach which, in combination with longevity convergence across countries, is posited as leading to rapid longevity growth. Where official UN projections arrive at an average life expectancy of ca 85 years in 2050, Nomura models predict ca 90 years. 

Redefining Old refers to another interesting aspect of the paper: Whereas a social security definition in terms of years lived will lead to an increasing share of the "old" cohort burdening social security, the authors argue that with increasing healthy life expectancy due to morbidity compression, it will be reasonable (i.e. necessary) to expect people to work (much) longer. The authors pinpoint that age at about 80, which would be suicidal for any politician to ask for. Note that this blog has argued for the same number before.

Virtually unseen in brokerage research is the extensive, up-to-date scientific apparatus provided. The label useful is fully deserved.

As a side comment: In spite of Switzerland's claim of having an exemplary retirement system that is the envy of the world, her only (and favourable) appearance in the paper is in a table about obesity ...

Death and taxes ...

This is an excellent presentation by Governor Jens Thomsen of the National Bank of Denmark, on how to hedge and invest in an environment where average life expectancy rises by over 5 hours every day. He proposes that governments should issue more ultra-long term bonds to create a hedging substrate for that time horizon. 

What Thomsen does not address, however, is the challenge to such instruments arising from an investment environment with massively higher government debt, as it is foreseeable in many countries. The temptation to apply the inflation tax to reduce such debt may be overwhelming, which is why such ultra-long bonds should be issued with an inflation protection.

Innovative ways of financing retirement

In this day and age where financial innovation is (wrongly!) blamed for the end of capitalism and the world as we know it lock, stock and barrel, the title of SwissRe's latest edition of Sigma is courageous. Nevertheless, it is a comprehensive assessment of the growing role that insurance will have to play in the provision of old age retirement funding, where insurance is to be understood in a functional rather than an institutional sense. 

An important section of the study is dedicated to managing retirement product risks. Longevity risk is identified as prominent among them, but its management is limited by the rather shallow depth and breadth of longevity risk markets. Notably absent from that section, however, are considerations on valuation techniques. If there is one thing that we can learn from the current crisis, then it is how crucially important it is to value & stress test innovative products properly over their entire life cycle.

Swiss management of longevity

Influential Swiss newspaper NZZ has a good article (in German) about how Swiss Pensionskassen manage their longevity risks, i.e. not very much. The article claims that due to the usage of backward looking mortality tables, the longevity of members is systematically underestimated in a world of continuously rising longevity. Unfortunately the article does not take into consideration the experience in more advanced countries such as the UK. This is a valid issue which receives too little attention because of a rigid regulatory environment in Switzerland where many important parameters are politically determined with little consideration to factual developments.

CEIOPS State of Pensions Report

CEIOPS' Report on financial conditions and financial stability in the European Insurance and Occupational pension fund sectors has a good section (starting p. 22) about recent developments in the European pension funds market, giving insights into last year's changes in a number of countries and a statistical overview, based on Eurostat.

The nemesis of pensions?

Is this man the nemesis of funded retirement systems? At any rate, Aubrey de Grey's work on life extension by regarding ageing as a curable disease gains increasing attention and traction, as witnessed by a veritable burst of recent media coverage such as Wired's. If his claim that life expectancy of about 120 years may be achievable to currently living generations, this would indeed pose a major challenge to retirement systems which rely on predictable mortality tables that shift slowly. Hence this space is certainly worth while watching for black swan risks.

Longevity concerns

The Economist brings us up to scratch on Abolishing Ageing, highlighting those areas of medicine which directly address ageing itself. For obvious reasons, this is an area of science that the retirement industry needs to watch closely, even though the current trend towards widespread obesity would not suggest that the most immediately promising approach of caloric restriction could win a popularity contest. But it could, once the side effects of caloric restriction (i.e. near starvation) are removed. Even so, the UK industry prepares for even higher longevity - some mortality tables expecting the average 65-year-old to live to 100 and beyond by 2050. 

It is therefore apprpriate that the finance industry provides tradable longevity indices, such as Goldman Sachs' QxX family, or JPMorgan's Lifemetrics toolkit. Credit Suisse's Longevity Index does not appear to be directly accessible on the web.
