Options and other derivatives
Listed options since 1973· Asset or instrument
Fact, law or dataA rule, statute, definition or measured number.
Derivatives are contracts whose value comes from something else, such as a stock, index, interest rate or commodity; options are the best known.
See it on the Money & Finance map →How it works
A call option gives the right, not the duty, to buy a stock at a set 'strike' price by a set date; a put gives the right to sell. The buyer pays a premium up front and can lose only that. Futures oblige both sides to trade later at a price set today; swaps exchange payment streams, such as fixed for floating interest. Listed options began at the Chicago Board Options Exchange in April 1973, the year the Black-Scholes pricing formula was published.
Why it matters
They let farmers, airlines, banks and investors shift risk to someone willing to bear it, but they also allow large, leveraged bets.
Think of it like
A call option works like a paid purchase option on a building: a small fee locks in the price, and you may walk away.
Facts, rules and data
Exchange records and Bank for International Settlements surveys: over-the-counter derivatives total roughly $700 trillion in notional value (2024), though the money actually at risk is far smaller.
Debates and risks
Whether derivatives mostly spread risk or concentrate it in a few big dealers, and whether booming same-day options trading by individuals is healthy, are debated.

Connections (11)
▸Options and other derivatives include Futures contractsFact, law or data
The connection
Futures are one of the four main derivative families, with options, forwards and swaps. Unlike custom swaps, they are standardized, exchange-traded and cleared, so the exchange's clearinghouse guarantees each trade. Options on futures combine the two.
When and why
Grain futures at the Chicago Board of Trade from 1865; currency futures in 1972; stock-index futures in 1982 in Kansas City and Chicago.
How we know
Definitions in the Commodity Exchange Act and CFTC rules; exchange volume data from CME Group and the Futures Industry Association.
Debates and risks
Where to draw lines among futures, swaps and securities, which decides whether the CFTC or SEC regulates, has been fought over for decades.
▸Options and other derivatives are split between the SEC and Commodity Futures Trading Commission (CFTC)Fact, law or data
The connection
US derivatives oversight is split by history. Options on individual stocks and stock indexes, like those traded on Cboe, are securities under the SEC. Futures and options on futures, including stock-index futures, belong to the CFTC. Dodd–Frank split swaps the same way: most to the CFTC, 'security-based' swaps to the SEC.
When and why
The 1982 Shad–Johnson Accord between SEC chair John Shad and CFTC chair Philip Johnson drew the line; Dodd–Frank (2010) extended it to swaps.
How we know
Congress wrote the accord into law in 1982; Title VII of Dodd–Frank assigns swap jurisdiction to each agency.
Debates and risks
Most countries have one markets regulator; proposals to merge the SEC and CFTC recur but stall over congressional committee turf. Crypto has revived the boundary fight.
▸AIG and credit default swaps showed the danger of Options and other derivativesFact, law or data
The connection
AIG's Financial Products unit sold credit default swaps, insurance-like contracts paying out if bonds defaulted, on about $440 billion of debt, much of it tied to mortgages, without setting aside reserves. When its rating was cut and the bonds fell, buyers demanded collateral it could not post. Unregulated, uncleared derivatives had concentrated risk in one firm.
When and why
AIG Financial Products, run largely from London; the US government rescue began September 16, 2008, eventually committing about $182 billion.
How we know
The Financial Crisis Inquiry Commission report (2011), the Congressional Oversight Panel (2010) and AIG's filings; Dodd-Frank then required clearing and reporting for standard swaps.
Debates and risks
Whether the rescue was needed to prevent wider collapse, and whether paying trading partners like Goldman Sachs in full was justified.
▸Warren Buffett and value investing called 'weapons of mass destruction' Options and other derivativesFact, law or data
The connection
In his 2002 letter Buffett called derivatives 'financial weapons of mass destruction', warning that hidden leverage and murky valuations could chain firms together in a crisis. He spoke from experience: unwinding General Re's derivatives book cost Berkshire about $400 million. Yet Berkshire also sold long-dated index put options it considered mispriced.
When and why
Berkshire Hathaway's letter for 2002, published in March 2003; the General Re Securities wind-down began in 2002 and ran for several years.
How we know
The letter text and Berkshire's annual reports, which disclose the Gen Re losses and its own put contracts.
Debates and risks
Whether AIG's 2008 collapse vindicated him, and how to square the warning with Berkshire's own large derivative bets, are still discussed.
▸Black Monday crash (1987) was worsened by 'portfolio insurance' using Options and other derivativesMainstream view
The connection
'Portfolio insurance' sold S&P 500 index futures as stocks fell, to mimic a protective put option. On October 19, 1987, that selling drove futures below stock prices; arbitrageurs then sold stocks, which triggered more insurance selling, a feedback loop. The Dow fell 22.6% in one day, its worst ever.
When and why
Chicago's S&P 500 futures pit and the New York Stock Exchange, October 19, 1987; an estimated $60 billion to $90 billion was covered by such strategies.
How solid is the link?
The Brady Commission report (January 1988) blamed portfolio insurance and the futures-stock link; exchanges later added circuit breakers.
Debates and risks
How much portfolio insurance caused the crash versus speeding it up is debated; markets fell worldwide, including where it was little used.
▸Interest-rate caps on floating-rate loans are a type of Options and other derivativesFact, law or data
The connection
A rate cap is a string of call options on a benchmark rate, one for each period: if SOFR sets above the strike, that option pays the difference. Like any option, its price depends on the strike, time, the expected path of rates and volatility, and the buyer can lose only the premium.
When and why
Traded privately between dealers and borrowers since the 1980s, usually documented as ISDA confirmations.
How we know
Standard option-pricing models, such as Black's model for caps, used by dealers and hedging advisers; ISDA cap confirmations.
Debates and risks
How fairly dealers price caps for small borrowers, who rarely compare quotes, is hard to know.
▸Interest-rate swaps: trading floating payments for fixed are the largest type of Options and other derivativesFact, law or data
The connection
A derivative is a contract whose value comes from something else, here an interest rate. Swaps are private, over-the-counter contracts rather than exchange-listed options, and interest-rate contracts make up about four-fifths of the roughly $850 trillion notional value of OTC derivatives (BIS, 2025).
When and why
A global market centered in London and New York; dealers include JPMorgan, Goldman Sachs, Citi and large European banks.
How we know
BIS semiannual OTC derivatives statistics and swap data repository reports required by Dodd–Frank and EU rules.
Debates and risks
Notional value hugely overstates risk; market value is a small fraction, and net exposure after collateral smaller still, but hard to pin down.
▸Swap loans: a floating bank loan fixed with an interest-rate swap make the borrower a counterparty in Options and other derivativesFact, law or data
The connection
Signing the swap makes the owner a derivatives counterparty. The contract is marked to market: its value can be a liability or an asset, and it is settled at that value if ended early. The borrower must qualify as an 'eligible contract participant', and its guarantors may need to as well.
When and why
US property borrowers since banks popularized swap loans in the 1990s–2010s; in the UK, swaps sold to small firms became a 2012 scandal.
How we know
Commodity Exchange Act rules on eligible contract participants, ISDA documents, and the UK FCA's 2012–16 redress program, about £2.2 billion.
Debates and risks
How well banks explain swap risk to property owners, versus relying on boilerplate disclosures, remains contested.
▸Deutsche Börse: the Frankfurt exchange and the DAX runs Eurex, a giant in Options and other derivativesFact, law or data
The connection
Eurex, Deutsche Börse's derivatives exchange, formed in 1998 by merging Germany's DTB with Switzerland's SOFFEX. Its fully electronic trading won business from floor-based rivals, and it is now one of the world's largest derivatives exchanges, trading Euro Stoxx 50 and DAX futures and options and German bond futures, and clearing interest-rate swaps.
When and why
Frankfurt and Zurich, 1998; Eurex Clearing in Frankfurt is its central counterparty.
How we know
FIA annual exchange volume rankings and Eurex and Deutsche Börse annual reports.
Debates and risks
Whether EU rules will move much euro swap clearing from London's LCH to Eurex, and how much business would really shift.
▸Korea Exchange (KRX): Korea's stock and futures market once hosted the world's most-traded option among Options and other derivativesFact, law or data
The connection
KOSPI 200 options were small, cheap to trade and untaxed, so Korean individuals traded them heavily. In 2011 about 3.67 billion contracts changed hands, the most of any derivative in the world. In 2012 regulators raised the contract size fivefold to cool speculation, and volume fell by more than half that year.
When and why
Korea Exchange, Busan and Seoul; the options launched in 1997, and the Financial Services Commission's rule changes came in 2011–12.
How we know
FIA annual volume surveys and Korea Exchange statistics.
Debates and risks
Whether the curbs protected investors or simply pushed Korean speculators toward US-listed leveraged ETFs and other markets.
▸India's exchanges: NSE and BSE (Nifty 50 and Sensex) run the world's busiest market in Options and other derivativesFact, law or data
The connection
NSE trades more derivatives contracts than any other exchange, mostly cheap weekly index options on the Nifty and Bank Nifty. A SEBI study found 93% of individual traders lost money from FY2022 to FY2024, more than ₹1.8 lakh crore (about $21 billion) in all. SEBI then raised contract sizes and limited weekly expiries.
When and why
Mumbai; NSE ranked first by contracts in FIA data in most years since 2019, and SEBI's curbs took effect from November 2024.
How we know
FIA annual volume statistics, SEBI's September 2024 study of individual traders, and SEBI circulars.
Debates and risks
Whether big trading firms profit unfairly; in July 2025 SEBI temporarily barred US firm Jane Street, alleging index manipulation, which the firm disputes.
