Exceptions

We have all heard the saying, “the exception that proves the rule”.  I have to admit that I have never really grasped the meaning of this statement, although I realize it is always said when there is a clear exception to a rule.

 

In risk we always have to deal with exceptions.  In fact I would argue that exceptions are the rule of risk management.  Without exceptions there would not be a field or an industry of risk management.  Without exceptions we would not have schools or degrees in risk management.  Without exceptions I would have to find something else to blog about.

 

The tough question of risk management however is how do we deal with exceptions.  How do our risk models incorporate exceptions?  The toughest question of all perhaps is deciding when to abandon the risk protocol for an exception – in essence deciding when an exception is exceptional (assuming that is not an oxymoron).

Backtesting

Coming from a background in investments (and nuclear physics), we always talk about back-testing a new idea.  In other words, how would have the world unfolded (differently, better, worse) if we implemented (did not implement) a given strategy.  Back-testing however seems to be a rarity in the world of risk management (with the possible exception of financial risk management).  Perhaps this is a major oversight of the profession. 

 

I realize that back-testing operational or strategic risk is tricky.  A lot of assumptions need to be made, and models of outcomes need to be constructed.  Perhaps however it is the exercise of working through the necessary assumptions and constructing the models that would make it such a useful and valuable exercise.

ERM Course – I Need Your Help

I am putting together a new Enterprise Risk management Course for my MBA students.  I would love to hear suggestions from my readers as to what I should include.  Any suggestions you have for readings, papers, topic suggestions would be most welcomed. 

 

I have put together now four major ERM courses and this will be my 5th version where I have started from scratch.  The one interesting thing about teaching ERM is that the field is still so young and still rapidly evolving that each new version allows for a fresh look at things.  I look forward to hearing your suggestions.

Steve Jobs as Risk Manager

Just finished the Steve Jobs biography.  Interesting book about an interesting person.  Not sure if it is a biography on how to be a manager (rip people apart, be ruthless, demand nothing but perfection, be a rebel, think differently, be obsessed with design, be obsessed) or how not to be a manager (see previous set of parentheses).  Interesting to think though about what Steve Jobs would be like as a risk manager.  Would his qualities be an asset, or a liability?

Tebow Stats

Like many of you I sat and watched with a sense of expectation as Tim Tebow played awful for three quarters against the Chicago Bears last weekend.  I kept watching the game in part because Tebow (and the Broncos in general) were playing in such a mediocre fashion.  We all know the script – Tebow sucks statistically for three quarters and then in the fourth quarter comes to life to impossibly pull the game out of the hat for a win for the Broncos.

 

I suspect that the dismal performance of the Broncos for three quarters, only to pull out the game after coming from behind is making Rolaids addicts out of the Broncos coaching staff and management.  The fans however seem to love it.  The only stat that fans know about in the final analysis is who won.  The vast majority of fans are not at all concerned with how the win occurs.  A win is a win.  Stats are simply things to debate in the off-season when there is nothing else to talk about.  Broadcasters, coaches and managers seem to be the only ones concerned about performance statistics.

 

Now shifting back to risk management, which they tell me is supposed to be the purpose of my rambling – but thankfully short – blogs.  Are risk managers more concerned about stats (i.e. VAR, risk weightings, volatility levels etc.) or are we more concerned with outcomes?  The answer should be obvious, but I am not sure that it is.  In my working with risk managers, they often seem more concerned that their numbers look good, and less concerned about the actual outcome (assuming of course that the numbers looked good beforehand).  Perhaps risk managers should be more like the fans and more concerned about outcomes. 

 

Sometimes the numbers suck, but the desired result occurs.  Sometimes the numbers are great but the outcome sucks.  Sometimes uncertainty occurs.  (Did I say “sometimes” in the previous sentence – I meant “always”.)  Stats are stats, and wins are wins.  Sometimes (always) it really is that simple.

Risk Genius

Genius has many definitions.  Genius is often thought of at performing at a superb level of intelligence.  However genius was once described to me in this fashion; someone who thinks superbly has a superb intelligence, a genius however thinks differently.  A genius is not more and faster intelligence.  Genius is a different kind of intelligence.

 

It is my opinion that the risk industry (and in particular in the financial sector) has a lot of extremely intelligent people.  However there are few, if any geniuses at work.  A group of really intelligent people are like a group of lemmings – except they are really efficient and quick lemmings – they get to a higher cliff, much quicker than more ordinary mortals.

 

Risk (and in particular, financial risk) needs some geniuses.

Trouble in Paradise

                                                                  There’s trouble in paradise

                                                                  And Heaven’s not the same,

 

These are lyrics from a doo-wop song by the Crests that can be applied to risk management and stop-gap measures proposed by Eurozone officials to stabilize financial markets.  This can describe the Brussels deal last week that attempts to reformulate the underlying rules for the euro zone.  The problem is that the full details were not disclosed and already it is falling short of market expectations.

 

There are a number of unresolved issues from the meeting:  there are no details on how much money will be needed to protect the market from further speculative attacks and prevent contagion, how will the banks be recapitalized to cover losses on their sovereign debt holdings, there is limited information on what measures will be implemented to reduce the borrowing costs and does the cure proposed in Brussels actually work?

 

The amount of European debt that needs to rollover in the next 12-24 months is staggering compared to the amounts discussed for a temporary financing facility.  The outstanding sovereign debt of Italy is nearly $3 trillion that would dwarf any temporary financing facility being considered.  A rating down-grade could spark another speculative attack.

 

The recent stress tests for the European banks suggest a further need for $150 - $200 billion in new capital.  This does not take into account any further write-offs of existing debt.  In addition, the banks are often under intense pressure in their country of domicile to take on additional sovereign debt after poor auctions.   If the sovereign debt crisis moves into a full blown banking crisis, the speed of contagion will increase rapidly.

 

The borrowing costs of a number of countries have increased to near-record levels in recent auctions.  The issue of borrowings costs has not been adequately addressed and may not be reduced until financial markets are stabilized.  Details of how this is being implemented are lacking.

 

There have been a number of measures proposed to promote fiscal discipline, central oversight by Eurozone authorities and rules to discipline countries that break the debt limits.  The idea is that once these rules are in place, the ECB and Eurozone officials could do more to resolve the underlying problems.  However, this is rehashing old issues that were in the earlier treaty and raise issues about national sovereignty.  There is some doubt that all countries will accept the proposed changes.

 

There is another issue not addressed by authorities and that is the persistence of imbalances and the lack of economic growth.  A number of countries are experiencing problems from lack of growth and not budget management.  There is concern that fiscal austerity will blunt growth and actually worsen the debt problem.  Eurozone officials need to consider lessons from the 1930s and not just the 1990s.

 

The ECB needs to take a more active role in ring-fencing the crisis and act as a lender of last-resort (such as debt purchases in the secondary market).  Officials need to provide a larger financing facility to deal with the crisis.  Otherwise, there will be further trouble in paradise.
