The Major Risks of Derivatives
The ways futures, forwards, swaps, and options go wrong, sorted into a handful of kinds, with two documented failures that show how they combine: a hedge fund in 1998 and an insurer in 2008. And how derivatives reach ordinary investors inside other products.
The short version
Derivatives fail in a small number of ways: leverage that turns a small move into a large loss, cash calls that force sales at the worst time, a counterparty that can't pay, a model that assumed the future would look like the past, a contract that doesn't track what it was meant to, and complexity that hides all of these. In 1998 a hedge fund levered through derivatives lost half its capital in a month when markets broke from its models, and the Federal Reserve helped arrange its rescue to avoid a fire sale. In 2008 an insurer that had sold protection through credit default swaps needed government loans. For most individuals, the risk arrives inside a fund or note, so the useful question is what derivatives a product holds and why.
By the end of this lesson, you'll be able to
- Name the main kinds of derivatives risk and give an example of each
- Explain how leverage, liquidity, models, and counterparties combined in the failures of 1998 and 2008
- Ask the right questions about a product that uses derivatives
Why this matters
The lessons in this track have each shown one way a derivative can hurt its user. Real failures rarely involve just one. They happen when several of these risks arrive together, usually in a market under stress, and usually to people who believed they'd understood them. This lesson sorts the risks into kinds and then looks at two cases documented by the Federal Reserve, chosen because each shows the kinds combining. It ends with where an ordinary investor actually meets these risks.
Six kinds of risk
| Risk | What it is | Where this track showed it |
|---|---|---|
| Leverage | A small deposit controls a large position, so a small move is a large gain or loss | A 6.7% fall in wheat erasing the margin on a contract |
| Liquidity and funding | Losses must be paid in cash before the position recovers, or a position can't be sold at a fair price | A trader closed out at the low by a margin call |
| Counterparty | The other side fails to pay what it owes | A swap worth $433,000 to a company, owed by a bank |
| Model | A pricing or risk model is wrong, often because the future breaks from the past | The VIX at 15.6 the day before a month of 87% volatility |
| Basis and structure | The contract doesn't move with what it was meant to track | Futures funds losing to contango, and oil below zero |
| Complexity | The position is understood less well than its owner thinks | A hedged spread left unhedged by one assignment |
On the last of these, the options disclosure document says it outright: a complexity not well understood is, in itself, a risk factor.1 It belongs on the list because it's what lets the other five go unnoticed.
1998: leverage meets a model
Long-Term Capital Management was a hedge fund founded in 1994, prominent for the talent of its people in pricing and trading and for its large starting capital. The account here follows the Federal Reserve chairman's testimony to Congress in October 1998.2
- The strategy. The fund mainly made judgments on interest rate spreads and the volatility of market prices. It levered its capital through repurchase agreements and derivatives, relying on sophisticated mathematical models. As long as returns followed their historical patterns, the models could find small, temporary anomalies in prices.
- More leverage for thinner returns. As those opportunities shrank, the fund returned $2.75 billion of capital to investors at the end of 1997, and then apparently reached for return by using more leverage and taking more risk.
- The break. In August 1998, a surge in risk aversion opened interest rate spreads dramatically, in an environment at variance with the experience built into the models. By the end of August the fund had lost half its capital, and it didn't significantly unwind its positions.
- The fear. Officials at the Federal Reserve Bank of New York judged that a forced liquidation of the portfolio, a fire sale, could distort market prices and produce large losses for creditors, counterparties, and other market participants who weren't directly involved.
- The outcome. On 23 September, private firms agreed a capital infusion of about $3.5 billion, substantially diluting the existing owners, with the aim of shrinking the portfolio in an orderly way. The Federal Reserve facilitated the agreement.
Every kind of risk in the table is there. The leverage made a spread move fatal. The models were built on a past that didn't repeat. The positions were too large to sell without moving prices, which turned a loss into a potential fire sale. And the fund's creditors and counterparties, including banks, were exposed to its failure, which is why a private loss became a public concern.
