Non-Deliverable Forwards (NDFs) Explained

A company with cash flows in the Indian rupee, Chinese yuan, or Brazilian real faces a problem a standard FX forward can't always solve: many emerging market currencies are subject to capital controls or limited convertibility, which makes physically delivering that currency offshore difficult or impossible. Non-deliverable forwards were developed precisely to let companies and investors hedge exposure to these currencies without ever needing to exchange the restricted currency itself.

What a Non-Deliverable Forward Is

A non-deliverable forward, or NDF, is a cash-settled forward contract on a currency pair where one leg is typically a freely convertible currency, such as the US dollar, and the other is a currency with trading or convertibility restrictions. Unlike a standard FX forward, which is settled by physically exchanging the two currencies at the agreed rate, an NDF never involves actual delivery of the restricted currency. Instead, on the settlement date, the contract is settled in cash, usually in US dollars, based on the difference between the agreed forward rate and the prevailing spot rate, referenced against a published fixing rate for the restricted currency.

How NDF Settlement Works

Suppose a company agrees an NDF to sell 100 million Indian rupees against US dollars at a forward rate of 84.00 in three months. On the settlement date, the actual spot rate is compared to that agreed rate using an official fixing source, such as the Reserve Bank of India's reference rate. If the rupee has weakened to 85.00, the party who agreed to sell rupees at 84.00 receives a cash payment reflecting the difference, denominated in dollars, equivalent to the gain they would have made had they been able to deliver the actual currency. No rupees change hands at any point; only the net dollar difference is settled.

Why Companies and Investors Use NDFs

NDFs let multinational companies, exporters and portfolio investors hedge currency risk in markets where local regulations restrict who can hold or transfer the currency offshore, or where onshore forward markets are illiquid or inaccessible to foreign participants. A company invoicing a customer in Chinese yuan, for example, can use an NDF to lock in an effective exchange rate for converting that future receivable into dollars, protecting its margin even though it may never be able to trade yuan freely outside mainland China. Hedge funds and asset managers also use NDFs to take directional views on restricted currencies without needing onshore market access.

NDFs Compared with Deliverable Forwards and Swaptions

A standard deliverable FX forward settles with a genuine exchange of two currencies, which only works where both currencies are freely convertible and liquid offshore. An NDF solves for the cases where that isn't possible, trading convertibility for cash settlement against a reference fixing. This is a similar idea in spirit to how an interest rate swaption allows a party to gain exposure to a rate move through an option rather than a physical swap obligation; in both cases, the derivative is structured to deliver the economic exposure without requiring the full underlying transaction. Pricing for an NDF also follows the same interest rate differential logic used for standard forwards, which is explained in more depth in Learnsignal's guide to how FX forwards are priced.

Key Risks in the NDF Market

Because NDFs are settled against an official fixing rate, fixing risk is a real consideration: if a government suspends publication of the reference rate, imposes a sudden devaluation, or changes how the fixing is calculated, settlement can become contentious or delayed. NDFs also carry counterparty credit risk like any over-the-counter derivative, since the cash settlement obligation depends on the counterparty actually paying. Liquidity can also thin out sharply around periods of currency stress, widening the gap between the forward rate quoted and the rate a company could realistically achieve, which matters for any treasury team relying on NDFs as part of its broader foreign exchange management strategy.

Where NDFs Are Most Commonly Used

The most actively traded NDF currencies include the Chinese yuan (traded offshore as CNH), Indian rupee, Brazilian real, South Korean won, Taiwanese dollar and Indonesian rupiah, among others. As some of these markets have gradually liberalised, deliverable forward markets have developed alongside the NDF market, and companies increasingly choose between the two based on which offers better liquidity and pricing for their specific hedging horizon, rather than NDFs being the only option.

NDFs in Finance and Treasury Roles

For corporate treasurers, risk managers and accountants working with multinational businesses, understanding NDF mechanics is increasingly a practical requirement rather than a specialist niche, given how much global trade and investment now flows through emerging markets with restricted currencies. Being able to explain why an NDF is being used, how its fixing risk differs from a deliverable forward, and how it should be accounted for under hedge accounting rules is a skill that comes up directly in treasury and financial management modules covered in Learnsignal's CPD courses.

FAQ

Is an NDF the same as a currency swap?
No. An NDF is a single cash-settled forward contract for one future date, while a currency swap typically involves an exchange of principal and periodic interest payments in two currencies over a longer term.

Who sets the fixing rate used to settle an NDF?
It's usually a central bank or an independent financial data provider publishing an official daily reference rate for the restricted currency, agreed in the contract terms before the trade is executed.

Can retail investors trade NDFs?
NDFs are primarily an institutional, over-the-counter product used by banks, corporates and asset managers; they are not typically available to retail investors through standard trading platforms.
