Where do FX futures and options fit?
Futures and options have their own courses in the Derivatives domain — contract mechanics, margin, mark-to-market, payoffs and the Greeks all live there and are not repeated here. What is specific to currencies is the question of why the wholesale FX market still runs mostly on OTC forwards, with listed alternatives sitting right there.
FX futures — the same arithmetic, standardised
A currency future is a forward with the terms frozen and a clearing house in the middle:
- Fixed contract sizes. Euro futures are EUR 125,000; sterling GBP 62,500; yen JPY 12,500,000. Micro versions are a tenth of the size.
- Fixed expiries. The quarterly cycle — March, June, September, December — expiring around the third Wednesday of the month.
- Central clearing. Your counterparty is the clearing house, not a bank, and positions are marked to market daily with variation margin.
Two FX-specific quirks are worth knowing. First, the price is the same forward arithmetic from Unit 2: the future trades away from spot by the interest differential, and converges to spot at expiry. Nothing new is being priced.
Second, the quoting convention is inverted relative to the spot market. Listed currency futures are quoted in US dollars per unit of the foreign currency. A yen future at 0.006667 is the same rate that the spot market quotes as USD/JPY 150.00. Anyone moving between screens has to flip the number, and mixing the two up is a classic error.
Why institutions still prefer OTC forwards
If futures are cleared, transparent and standardised, why is the forward market vastly larger? Because a hedge has to match a real cash flow:
- Exact amount. A receivable of USD 4,317,500 does not divide neatly into contracts of EUR 125,000.
- Exact date. Payment lands on 14 May, not the third Wednesday of June.
- No daily cash calls. A cleared future demands variation margin in cash every day; a forward under a credit line may demand none. A treasurer hedging a commercial receivable would rather not create a daily liquidity obligation to protect against a risk that settles once.
Futures win where standardisation is an advantage: rapid position-taking, transparent pricing, and no bilateral credit relationship required.
FX options — quoted in volatility
The distinctive feature of the OTC currency option market is that dealers quote implied volatility, not price. A dealer says "one-month EUR/USD at 7.2" and both sides run the same pricing model to turn that into a premium. Structure is quoted through three standard building blocks: the at-the-money volatility, the 25-delta risk reversal (how much more expensive calls are than puts, a direct read on skew), and the butterfly (how much the wings cost over the middle).
The second quirk is the expiry cut. An FX option does not expire at a market close, because there isn't one — it expires at a named time in a named city. The 10:00 New York cut is standard for most pairs, the 15:00 Tokyo cut common for yen. Large option expiries clustered at round strikes can visibly hold spot near those strikes as the cut approaches, which is why "expiries" appear in professional FX commentary.
Everything else — intrinsic and time value, the Greeks, payoff diagrams — is in the Derivatives domain. Learn it there once; it applies to every underlying.
Try it now
- The spot rate for a yen pair is below, quoted the market way round: yen per dollar. Read it, then take its reciprocal to get the futures convention, dollars per yen. Confirm you can move between the two without hesitating — a listed contract and an OTC quote on the same currency are printed upside down from each other.
- Take a hypothetical hedging need of USD 4,317,500 due on a specific date and work out how many standard futures contracts it would take, and what residual exposure is left over. That residual is why forwards exist.
- Note which Derivatives-domain course you would go to for option payoffs, and read it before reading any FX options commentary.
