NDFs are settled in cash based on the difference between the contracted and spot rates without physical delivery of currencies, whereas standard forward contracts involve the actual exchange of the underlying currencies at maturity.

The RBI's prohibition on Indian banks from entering new NDF contracts and rebooking cancelled ones aims to curb offshore speculative pressures and regain control over rupee volatility. This move is perceived as a step towards greater regulatory control and potentially stabilizing the rupee by reducing external speculative bets. However, it might also lead to reduced offshore liquidity and potentially push some trading activity to less regulated platforms.

Hedging with NDFs involves locking in a future exchange rate to protect against adverse currency movements for existing or planned transactions. Speculation, on the other hand, involves taking a position solely to profit from anticipated currency fluctuations, without any underlying commercial or investment exposure. This speculative activity can amplify currency volatility, especially during times of economic uncertainty, potentially destabilizing the domestic currency and impacting monetary policy objectives, which is why regulators monitor it closely.

NDFs are customized, over-the-counter (OTC) contracts primarily used for hedging or speculating on non-convertible currencies, settled in cash. Currency futures are standardized contracts traded on exchanges, available for both convertible and non-convertible currencies, and also involve cash settlement based on exchange rates.

The RBI's move curbed offshore speculative selling of the rupee. When foreign entities could freely bet against the rupee via NDFs, it exerted downward pressure. By restricting these avenues, the RBI reduced the supply of rupee-denominated bets against the dollar, effectively increasing demand for the actual rupee in the spot market and leading to its appreciation. It signals a stronger regulatory grip, discouraging bearish sentiment.

The 'non-deliverable' aspect means that at maturity, the parties do not exchange the principal amounts of the currencies specified in the contract. Instead, the difference between the contracted exchange rate and the prevailing market rate (spot rate) at maturity is calculated. This net difference is then paid in a freely convertible currency, usually USD, by the party that incurred the loss to the party that made the profit. This cash settlement is the defining feature.

Without NDFs, foreign portfolio investors would face significant challenges in hedging their currency exposure. This would increase the perceived risk of investing in such markets, potentially leading to lower foreign investment inflows, higher borrowing costs, and greater volatility in the local currency. Investors might avoid these markets altogether or demand a much higher risk premium, hindering economic development and integration.

The strongest criticism is that NDFs can amplify currency volatility and facilitate destabilizing speculation, especially in emerging markets. Critics argue that offshore NDF markets can create pressures that are disconnected from the actual domestic economic fundamentals. A policy response could involve enhanced monitoring of offshore NDF markets, international cooperation on regulatory oversight, and, as seen with the RBI's recent action, targeted restrictions on domestic entities' participation to regain control over currency stability.

The confusion arises because the settlement amount is calculated based on the *difference* between the NDF rate and the spot rate, and then this difference is divided by the spot rate to determine the payout in USD. For example, if an NDF contract is to buy USD 1 million at ₹80/USD, and the spot rate at maturity is ₹82/USD: The difference is ₹2/USD. The payout is calculated as (₹82 - ₹80) * USD 1 million / ₹82 = ₹2 million / ₹82, which is approximately USD 24,390. This formula ensures the payout reflects the actual change in value relative to the prevailing market rate.

Many emerging markets face similar challenges with capital controls and currency convertibility. Some countries might opt for more direct capital controls, while others might allow NDFs with stricter oversight or limitations on domestic bank participation, similar to India's recent move. Some may even permit more open NDF markets but focus on strong foreign exchange reserves to manage volatility. India's approach, characterized by periods of relative openness followed by sharp regulatory interventions like the April 2026 action, reflects a dynamic balancing act between attracting foreign capital and maintaining domestic currency stability.
