What are Bond Futures?

Bond futures are a key component of the global financial market, yet many investors still have limited knowledge and understanding of this complex financial instrument. This guide will provide a thorough overview of how bond futures work and equip investors with the necessary knowledge to make informed decisions regarding incorporating them into their investment portfolios.

About  Bond Futures

Bond futures are financial contracts that enable investors and traders to buy or sell a specific bond at a predetermined price on a future date. These contracts, commonly traded in the Indian financial markets, are crucial in managing risk and providing opportunities for hedging and speculation.

Investors and traders employ this tool to hedge against potential changes in interest rates. By entering into a bond futures contract, market participants can protect themselves from adverse movements in interest rates that could negatively impact the value of their bond holdings. 

For example, suppose an investor holds a portfolio of bonds and expects interest rates to rise. In that case, they can enter into a futures contract to sell those bonds at a predetermined price in the future, thus locking in a favourable selling price and mitigating potential losses.

On the other hand, these futures also offer opportunities for speculation. Traders can take positions in bond futures contracts based on their expectations of interest rate movements. Suppose a trader anticipates that interest rates will decrease. In that case, they can enter into a futures contract to buy bonds at a predetermined price, aiming to profit from the subsequent increase in bond values as interest rates decline.

How do Bond Futures Work?

Bond futures are derivative contracts that allow investors and traders to gain exposure to the price movements of underlying bonds without actually owning the bonds themselves. These futures contracts are standardised in terms of bond type, quality, and duration, ensuring consistency and liquidity in the market.

The process of trading involves several steps. 

  • Market participants initiate a contract by selecting a specific bond and its maturity date for trade, typically on an exchange.

  • Margin requirements are crucial once the contract is established. This initial deposit made by buyers or sellers covers potential losses, reducing default risk.

  • Margin requirements fluctuate based on factors like bond volatility and market conditions.

  • Daily settlement processes become essential as the market moves. At each trading day’s end, futures contracts are marked-to-market, meaning gains or losses are calculated and settled.

  • If the prices move in favour of the buyer, the seller pays the difference to the buyer. Conversely, if prices move against the buyer, the buyer pays the seller.

  • This daily settlement mechanism mitigates risk and ensures market participants are responsible for their positions.

  • Upon reaching the contract’s maturity date, settlement occurs. This involves either physical delivery of the bonds or cash settlement based on the agreed contract price.

  • The choice between physical delivery or cash settlement depends on factors like market liquidity and the investor’s preference.

Example of Bond Futures

Let’s consider a bond futures example

where a trader’s centralised interest rates will decrease in the future. They decide to take a long position in the contract, expecting the price of the underlying government securities to increase.

If interest rates decrease as anticipated, this would lead to an increase in the value of the contract. This is because lower interest rates typically result in higher bond prices. The impact of interest rate changes on pricing can be significant, as even small fluctuations in rates can substantially affect the value of the bond futures contract.

At the contract’s expiry, there are several potential outcomes. If the trader’s prediction was accurate and interest rates decreased, they could sell the contract at a higher price, realising a profit. However, if interest rates increased instead, the value of the contract would decline, resulting in a potential loss for the trader.

Notably, these outcomes are subject to market conditions and the accuracy of the trader’s predictions. Bond futures trading involves risks, and market participants should carefully assess their positions and monitor interest rate movements to make informed decisions.

How to Derive Cheapest Delivery?

The “cheapest to deliver” bond becomes crucial for traders in bond futures contracts. This refers to the bond yielding the lowest delivery cost when fulfilling the contract’s obligations. To identify the most cost-effective bond, traders consider various factors, including the interplay of market price, interest rates, and the conversion factor.

Market price plays a significant role in determining the cheapest way to deliver bonds. Traders look for bonds trading at a lower price relative to their face value. This allows them to purchase the bond at a discounted rate, reducing the delivery cost.

Interest rates also impact the selection of the cheapest to deliver bonds. When interest rates rise, bond prices tend to decrease. Therefore, traders seek bonds with higher coupon rates, as they provide higher interest payments and can offset potential price declines. 

Conversely, when interest rates decline, bonds with lower coupon rates become more attractive due to their potential for capital appreciation.

Conversion Factors

Conversion factors play a crucial role in bond futures contracts, ensuring that the futures contract’s price accurately represents the value of the delivered bond. These factors adjust for differences in coupon rates and maturity dates among eligible bonds.

Coupon rates refer to the interest payments made by the bond issuer to the bondholder. Bonds with different coupon rates will have varying cash flows over their lifetime. To account for this, conversion factors are employed to standardise the bond’s value by considering the present value of these cash flows.

Maturity dates also impact the value of a bond. Bonds with longer maturities generally have a higher risk profile, with a longer time frame for market conditions to change. Conversion factors accommodate this by adjusting the contract price based on the time remaining until maturity.

By incorporating conversion factors, contracts provide a mechanism for ensuring fairness and accuracy in pricing. Traders can confidently enter these contracts, knowing that the delivered bond’s value will align with the agreed-upon price. This allows for efficient hedging and speculation in the

bond market, enabling market participants to manage risk and capture opportunities related to interest rates and bond prices.

Bond Futures Pricing

In addition to coupon rates and maturity dates, several other factors influence the pricing of bond futures in the Indian market. One of the primary factors is interest rates. As interest rates fluctuate, the value of bonds and their corresponding futures contracts also change. Bond prices and interest rates have an inverse relationship – when interest rates rise, bond prices fall, and vice versa. This relationship is crucial in determining the pricing of bond futures contracts.

The underlying bond’s price also plays a significant role. The price of the underlying bond affects the futures price. Market participants closely monitor the underlying bond’s price movements to anticipate changes in the futures price.

Another crucial element is the cost of carry. This refers to the expenses associated with holding the bond until its maturity. These expenses include financing costs, storage fees, and any dividends or coupon payments received. The cost of carrying influences the futures price and is factored in when determining the contract’s value.

Understanding how these factors interrelate is essential for investors and traders in the Indian bond futures market. Market participants can make informed decisions and effectively manage their positions by analysing interest rates, the underlying bond’s price, time to maturity, and the cost of carry.


Bond futures can be useful for managing risk and hedging against potential losses in the bond market. However, they also require a thorough understanding of market trends and a strong risk management strategy to succeed. With proper research and diligence, bond futures can be a valuable asset in a well-rounded investment portfolio.
