The chapter describes simultaneous bond, stock-index and oil positions before diplomatic talks. When the talks fail, several prices move against the portfolio together. The author draws attention to the unpredictability of political developments.
Find the common assumption
Different instruments do not automatically mean different sources of risk. Write the assumption behind each position, then check whether the same event challenges several of them. The aim of this exercise is to understand concentration in a hypothetical portfolio.
Worked example
Three fictional positions all benefit if an agreement is reached. Holding three tickers has not diversified the risk of failed negotiations.
Case connection
Different markets can become one crowded liquidity exposure. A list of instruments is not a map of independent risks.
LTCM: a funding emergency
Source-grounded facts
Fourteen firms supplied $3.6 billion to prevent LTCM’s collapse. The Federal Reserve facilitated the arrangement without lending its own money.
Context
LTCM sought gains from price differences between related securities. Small spreads were supported by extensive borrowing; at the end of 1997 its debt was about thirty times its capital.
Outcome
The recapitalisation allowed an orderly reduction of positions. The Federal Reserve coordinated the arrangement without supplying its own funds; the original owners and investors still suffered substantial losses.
- In August 1998, Russia devalued its currency and stopped debt payments, pushing investors towards safer, more liquid assets.
- Spreads that LTCM expected to narrow widened instead. The fund lost 44% in August and sought fresh capital.
- Concern about simultaneous liquidation brought creditors together. Fourteen firms supplied roughly $3.6 billion in September.
Case analysis
Draw a portfolio map using dependencies rather than instrument names. Two trades in different markets may both rely on willing lenders, narrow spreads and counterparties staying active. Stress those shared conditions together. This identifies a possible concentration mechanism; it does not imply that correlations must always be identical or that all diversification is ineffective.
Try it
For three hypothetical positions, write the event that helps each and the event that hurts each. Circle repeated events.
