Understanding Bond Futures

Understanding Bond Futures

Let me tell you directly: bond futures are contracts that fix the future price of a government bond, protecting you from interest rate swings. These are financial derivatives that obligate you, as the contract holder, to purchase or sell a bond on a specified date at a predetermined price. You trade a bond futures contract on a futures exchange market, and you buy or sell it through a brokerage firm that offers futures trading. The contract's terms, including price and expiration date, are set when you purchase or sell the future.

Key Takeaways

Bond futures entitle you to purchase a bond on a specified date at a price determined today. You trade them on a futures exchange through a brokerage firm that handles futures. Speculators use them to bet on bond prices, while hedgers protect their bond holdings. Indirectly, you can use bond futures to trade or hedge interest rate moves.

How Bond Futures Work

A futures contract is an agreement between two parties where one agrees to buy and the other to sell an underlying asset at a predetermined price on a specified date. On the settlement date, the seller must deliver the asset to you as the buyer. The underlying asset could be a commodity or a financial instrument like a bond. For bond futures, the asset is a government or Treasury bond.

You can hold a bond futures contract until maturity, or close it out before then. If you close the position early, you'll see a profit or loss based on the contract's value at that time. These contracts are standardized by futures exchanges and are highly liquid, meaning plenty of buyers and sellers ensure smooth trades without delays. You use them for hedging to protect holdings, arbitrage to profit from price imbalances by buying on one exchange and selling on another, or speculating on high-risk, high-reward bond price movements to lock in a price for a future period.

Bond Futures Delivery

The seller of the bond futures can choose which bond to deliver to you. Typically, they deliver the cheapest-to-deliver (CTD) bonds on the last delivery date of the month. A CTD is the cheapest security that satisfies the contract terms. This is common with Treasury bond futures, where any Treasury bond within a specific maturity range and coupon rate can be used.

As a futures trader, you usually close positions well before delivery risks arise. Many brokers require you to offset positions or roll them to later months before expiration.

Bond Futures and Margin

Many futures contracts, including bond futures, require margin, so you need to deposit and maintain a specific amount in your brokerage account. This is much smaller than the contract's notional value and must be in place when you open the position. Your broker sets an initial margin and a maintenance margin. If the position declines in value, you might get a margin call demanding more funds.

Remember, futures margin differs from securities margin. In futures, it's the amount you maintain in the account to ensure both parties meet obligations at expiry—it doesn't fund your purchase or create leverage directly, but it's based on the asset's price.

Bond Futures Risks

Trading bond futures carries potentially unlimited risk for you as buyer or seller. The underlying bond's price could change drastically between the agreement and exercise date. Leverage in margin trading can make losses worse.

Where to Buy Bond Futures

You primarily trade bond futures on the Chicago Board of Trade (CBOT), part of the Chicago Mercantile Exchange (CME) Group. Contracts expire quarterly in March, June, September, and December.

Where to Buy Bond Futures Continued

Brokers like Charles Schwab, Interactive Brokers, and TradeStation offer bond futures.

Managing a Bond Futures Position

Each day before expiration, your long (buy) and short (sell) positions are marked to market, adjusted to current rates. When interest rates rise, bond prices decline because existing fixed-rate bonds become less attractive. If rates decrease, bond prices increase as investors buy those with attractive rates.

For example, if you enter a U.S. Treasury bond futures contract on Day One and rates rise on Day Two, the T-bond value decreases, debiting your long position's margin account for the loss while crediting the short trader's. If rates fall, your long account profits, and the short account is debited.

Fast Fact

Bond futures are overseen by the Commodity Futures Trading Commission (CFTC), which ensures fair trading practices, equality, consistency, and prevents fraud.

Bond Conversion Factors

Deliverable bonds are standardized through conversion factors calculated by exchange rules to equalize coupon and accrued interest differences. Accrued interest is the unpaid accumulated interest. If a contract specifies a 6% notional coupon, the factor is less than one for bonds under 6% and greater than one for those over 6%.

The exchange announces factors before trading. For instance, a 0.8112 factor means the bond is valued at about 81% of a 6% coupon security. On expiry, the price is (bond futures price x conversion factor) + accrued interest. The product of the factor and futures price is the forward price in the market.

Explain Like I'm 5

Bond futures are agreements between two parties to buy or sell government bonds later at a set price. Like all futures, you lock in a price for a future transaction. You can hold to maturity and get the bond or sell your position early without delivery. You use them for hedging to protect against big interest rate moves hurting your investments or for speculation to profit by guessing rate directions. They're highly regulated, standardized, and traded on exchanges.

What Is a Bond Future?

What Is the Difference Between Interest Rate Futures and Bond Futures?

The Bottom Line

Bond futures obligate you to buy or sell a bond at a predetermined price on a specific date. As a trader, you aim to profit from short-term price changes and usually close contracts before expiry to avoid delivery. Futures trading has benefits like potential high profits from fluctuating markets, but it also brings greater risks and drawbacks.
