A non-deliverable forward (NDF) is a foreign-exchange forward that settles in cash without physical delivery of the two underlying currencies. At maturity, the contracted forward rate is compared with a specified fixing rate, and one party pays the resulting net amount in an agreed settlement currency.
Key Takeaways
- An NDF creates economic exposure to an exchange rate without exchanging the reference currency notional.
- The notional amount is used to calculate settlement; it is not normally delivered.
- The fixing source, valuation date, quote direction, settlement formula, and disruption fallbacks are core contract terms.
- NDFs are often associated with currencies for which offshore delivery is restricted, limited, costly, or impractical, but market and legal conditions can change.
- Cash settlement removes physical delivery of the reference currency, not market, counterparty, liquidity, basis, or legal risk.
Core Contract Terms
An NDF confirmation commonly identifies:
| Term | What it controls |
|---|
| Reference currency | Currency whose exchange-rate movement creates the exposure |
| Settlement currency | Currency in which the net payment is made, often a major convertible currency |
| Notional amount | Reference amount used in the settlement calculation |
| NDF rate or forward rate | Exchange rate agreed on trade date |
| Valuation or fixing date | Date on which the settlement rate is observed |
| Settlement rate option | Named source or methodology for the fixing |
| Settlement date | Date on which the net cash amount is paid |
| Calculation agent | Party responsible for determining the settlement amount |
| Disruption events and fallbacks | Procedures for unavailable, delayed, or unreliable fixings |
The label “NDF” is not enough to calculate the payoff. Pair order and formula determine which party pays and how the amount is converted into the settlement currency.
NDF Lifecycle
- Trade date: The parties agree on notional, NDF rate, dates, settlement currency, and documentation.
- Contract period: The NDF changes value as spot rates, forward pricing, time, credit, and liquidity change.
- Fixing date: The specified exchange-rate source is observed under the confirmation’s rules.
- Calculation: The contracted rate and fixing rate are applied to the notional using the agreed formula.
- Settlement date: One net payment is made in the settlement currency.
No exchange of both notional currency amounts occurs at maturity. That is the central difference from a deliverable FX forward.
Worked Settlement Example
Assume a USD/BRL NDF uses:
- USD notional: USD 1,000,000
- contracted NDF rate: 5.20 BRL per USD
- fixing rate: 5.40 BRL per USD
- settlement currency: USD
For one common BRL-per-USD convention, the value to the party that contracted to buy USD at 5.20 can be illustrated as:
USD 1,000,000 x (5.40 - 5.20) / 5.40 = USD 37,037.04
The higher fixing means that buying USD at the contracted 5.20 rate is favorable relative to the 5.40 fixing, so the USD buyer receives the cash difference in this simplified example.
If the fixing were below 5.20, the payment direction would reverse. Actual confirmations may use a different quotation direction, notional convention, rounding method, or settlement formula. The signed contract and specified rate source control the legal payment, not a generic web formula.
NDF vs. Deliverable Forward
| Feature | NDF | Deliverable FX forward |
|---|
| Underlying currencies delivered | No | Yes, unless otherwise terminated or netted |
| Maturity cash flow | One net amount in settlement currency | Exchange of both currency principal amounts |
| Critical rate at maturity | Contractual fixing from specified source | Contracted exchange of currency amounts |
| Typical operational focus | fixing, formula, disruption fallback, net payment | funding and payment of both currency legs |
| Common use | Offshore exposure where delivery is constrained or impractical | Hedge or transact where currency delivery is available and required |
NDFs can approximate the economic price effect of a deliverable forward, but the markets are not always interchangeable. Onshore and offshore rates can diverge because of capital controls, funding, liquidity, participant access, and regulation.
Why Market Participants Use NDFs
NDFs may be used to:
- hedge a forecast payment, receipt, asset, or liability linked to a reference currency;
- manage offshore currency exposure without taking delivery of the currency;
- price or transfer risk where access to a local deliverable market is limited;
- express a market view; or
- intermediate customer currency risk.
An NDF does not itself create access to the local currency or guarantee that an underlying business cash flow can be converted. A company can settle the derivative in USD and still face local-currency controls, transfer restrictions, taxes, or operational constraints on the underlying exposure.
Fixing and Basis Risk
The settlement amount depends on the contract’s fixing. Relevant questions include:
- Is the source an onshore official rate, a benchmark, or another published rate?
- At what time and on what valuation date is it observed?
- What happens if the source is not published?
- Can the valuation date be postponed?
- Who determines an alternative rate?
- Does the fixing represent the rate at which the underlying exposure can actually be converted?
An NDF may hedge a commercial exposure imperfectly when the fixing differs from the company’s achievable conversion rate. That difference is a form of basis risk.
Market and Valuation Considerations
NDF value can respond to:
- spot and forward exchange-rate changes;
- relative interest rates and funding conditions;
- capital controls and convertibility expectations;
- offshore and onshore liquidity;
- counterparty credit and collateral terms;
- fixing methodology and disruption risk; and
- time remaining to valuation and settlement.
The NDF rate is not a guaranteed forecast of the future fixing. It is a contract price formed under current market conditions and access constraints.
How to Evaluate an NDF
- Identify the economic exposure and why a deliverable instrument is not being used.
- Confirm pair order, reference currency, settlement currency, and notional convention.
- Recalculate the payoff under the exact contractual formula.
- Verify fixing source, observation time, valuation date, and publication calendar.
- Review disruption events, fallbacks, calculation-agent discretion, and rounding.
- Match contract maturity and notional to the underlying exposure.
- Assess counterparty, collateral, netting, liquidity, and early-termination terms.
- Check local exchange controls, sanctions, tax, accounting, and legal requirements.
- Reconcile the fixing, calculation statement, and settlement payment.
Risks and Limitations
- Market risk: The NDF can move against the position.
- Counterparty risk: The other party may not pay the settlement amount.
- Liquidity risk: Pricing and exit costs can deteriorate, especially during market stress.
- Fixing risk: The specified rate can be delayed, disputed, unavailable, or unrepresentative.
- Basis risk: The fixing may not match the rate applicable to the underlying exposure.
- Control risk: Currency rules or market access can change during the contract.
- Collateral risk: Adverse valuation changes can create margin or liquidity demands.
- Operational risk: Pair direction, formula, date, or notional errors can reverse or distort the payment.
- Legal risk: Documentation, enforceability, closeout netting, and permitted use vary by jurisdiction.
Common Mistakes
- Assuming the reference-currency notional is delivered.
- Calling every cash-settled currency product an NDF without checking the contract.
- Using the current screen spot rate instead of the specified fixing.
- Ignoring quote direction in the settlement formula.
- Treating the NDF rate as a forecast.
- Assuming cash settlement eliminates currency controls or underlying conversion needs.
- Listing currencies as permanently “non-deliverable” without checking current rules and market practice.
- Forward Contract: The general bilateral contract, including deliverable FX settlement and its comparison with NDFs.
- Non-Deliverable Swap: A multi-period swap whose reference-currency cash flows are converted into a deliverable settlement currency.
- Forward Market: The broader OTC market for future-dated agreements.
- Spot Exchange Rate: The prompt-market rate, distinct from the NDF’s contractual fixing.
- Capital Controls: Rules that limit currency conversion, transfer, or market access.
- Counterparty Risk: Risk that the other party does not perform its obligation.

FAQs
Are the underlying currencies exchanged in an NDF?
No. The parties normally exchange one net cash amount in the agreed settlement currency. The reference-currency notional is used to calculate that amount.
Why does an NDF need a fixing rate?
The fixing provides the contractual rate used to compare the market outcome with the agreed NDF rate and calculate the settlement amount.
Does an NDF remove all risk from a restricted-currency exposure?
No. It can offset part of the exchange-rate effect, but basis, fixing, counterparty, liquidity, collateral, legal, and underlying conversion risks can remain.
