Objective
How financial markets can:
• Create risk
• Magnify existing risks
• Mitigate risks

How Financial Markets Create Crises
•
•
•
Liquidity – Nurtures a demand for immediacy
Leverage – Magnifies the damage if liquidity is lost
Innovation – Creates complex, vulnerable products
3
An Engineering View
Liquidity + Leverage => “Tight Coupling”
Innovation => “Complexity”

Result of Market Structure
Crises for no apparent reason…
1. Crash of 1987
Loss: Market value equal to one year’s GDP for Japan
2. LTCM Debacle
Loss: $1 Trillion of market value

How Financial Markets Can Magnify Crises
If no apparent event can cause such destruction of
value, think of what can happen if the markets end up
on the wrong side of a real event.

Can Financial Markets Mitigate Risk?
Objective of Financial Markets:
1. For non-systematic risks: Diversify risk away.
2. For systematic risks: Spread them out to dampen
effects.

What is Required for Financial Markets to Help?
1. A well-defined distribution. Necessary but not
sufficient: A well-defined event space.
OK: Flood, Earthquake, Hurricane
OK: Kidnapping
Not OK: “Weather-related”
Not OK: “Terrorist-related”
2.
No “gaming”.
Not OK: Moral Hazard
Not OK: Feedback

Looking at the Problem a Different Way
A well-defined event space.
OK: Fire – no matter what the cause
OK: Death – no matter what the cause.
OK: Fire – except for “Force Majeure”
OK: Death – except for “Force Majeure”

Securitization – and hence solutions from the
financial markets – must be proceeded by having
a market that can be securitized.
