Non-deliverable forward

In finance, a non-deliverable forward (NDF) is an outright forward or futures contract in which counterparties settle the difference between the contracted NDF price or rate and the prevailing spot price or rate on an agreed notional amount. It is used in various markets such as foreign exchange and commodities. NDFs are prevalent in some countries where forward FX trading has been banned by the government (usually as a means to prevent exchange rate volatility).

The NDF market is an over-the-counter market. NDFs began to trade actively in the 1990s. NDF markets developed for emerging markets with capital controls, where the currencies could not be delivered offshore. Most NDFs are cash-settled in US dollars (USD).

The more active banks quote NDFs from between one month to one year, although some would quote up to two years upon request. The most commonly traded NDF tenors are IMM dates, but banks also offer odd-dated NDFs. NDFs are typically quoted with the USD as the reference currency, and the settlement amount is also in USD.

Below is a (non-exhaustive) list of currencies where non-deliverable forwards are traded. Not all non-convertible currencies have a NDF market (e.g. BDT had no active market as of 2011). A currency may be convertible by some market participants while being non-convertible to others.

An NDF is a short-term, cash-settled currency forward between two counterparties. On the contracted settlement date, the profit or loss is adjusted between the two counterparties based on the difference between the contracted NDF rate and the prevailing spot FX rates on an agreed notional amount.

The features of an NDF include:

Because an NDF is a cash-settled instrument, the notional amount is never exchanged. The only exchange of cash flows is the difference between the NDF rate and the prevailing spot market rate—that is determined on the fixing date and exchanged on the settlement date—applied to the notional, i.e. cash flow = (NDF rate – spot rate) × notional.

Consequently, since NDF is a "non-cash", off-balance-sheet item and since the principal sums do not move, NDF bears much lower counter-party risk. NDFs are committed short-term instruments; both counterparties are committed and are obliged to honor the deal. Nevertheless, either counterparty can cancel an existing contract by entering into another offsetting deal at the prevailing market rate.
