Why some currencies trade this way
Many emerging-market currencies are subject to capital controls that restrict how freely they can be moved across borders, converted, or held offshore. A standard deliverable forward contract, which requires actually exchanging the two currencies at maturity, is impractical or illegal to settle under those restrictions. The NDF structure solves this by settling only the cash difference β usually in a widely convertible currency such as the US dollar β so no restricted currency ever needs to physically cross a border. This lets global investors and companies still manage currency exposure to markets that would otherwise be very difficult to hedge.
How the settlement price is determined
At the contract's maturity date, the payout is calculated by comparing the forward rate agreed at the start of the contract against a reference exchange rate, usually a published fixing rate from the onshore central bank or an interbank market average. Whichever party is on the losing side of that difference pays the other the cash equivalent, denominated in the convertible currency used to settle the contract. Because the fixing methodology and reference rate source vary by currency and market convention, and because currency markets carry meaningful risk, this is general information rather than trading advice β anyone evaluating currency exposure should consult a qualified financial professional familiar with the specific market involved.
Frequently Asked Questions
What is the difference between an NDF and a regular forward contract?
A regular (deliverable) forward requires both parties to actually exchange the underlying currencies at maturity. An NDF settles only the cash difference between the contracted rate and the market rate, so the restricted currency itself never needs to be delivered.
Why would offshore NDF pricing move before the onshore market opens?
Because NDFs trade around the clock in offshore hubs while the onshore market for a restricted currency may only be open during local business hours, NDF pricing can reflect breaking news or shifting sentiment before onshore trading resumes, which is why some traders watch it as an early indicator.
