The Treasury Bond Basis Explained
The treasury bond basis is essentially a measure of how much cheaper or more expensive a treasury bond is compared to its corresponding futures contract. It can be positive or negative, depending on whether the cash price is higher or lower than the futures price. A positive basis means that the cash price is higher than the futures price, indicating that the bond is trading at a premium. A negative basis means that the cash price is lower than the futures price, indicating that the bond is trading at a discount.
The treasury bond basis can also be interpreted as an indicator of the implied repo rate, which is the annualized interest rate that one can earn by buying a treasury bond in the cash market and selling it in the futures market (or vice versa). A positive basis implies a low implied repo rate, meaning that there is low demand for borrowing or lending treasury bonds. A negative basis implies a high implied repo rate, meaning that there is high demand for borrowing or lending treasury bonds.
But how is the treasury bond basis calculated and what are the factors that affect it? To answer these questions, we need to understand two important concepts: the delivery options and the cheapest-to-deliver bond.
Definition and Formula of the Treasury Bond Basis
The treasury bond basis can be calculated using the following formula:
treasury bond basis = cash price - futures price x conversion factor
The cash price is the market price of the treasury bond in the cash market. The futures price is the market price of the treasury bond futures contract in the futures market. The conversion factor is a number that adjusts the futures price to reflect the coupon and maturity of the treasury bond. The conversion factor is determined by the exchange that offers the futures contract, and it is based on a standard 6% coupon and a maturity of 20 years.
The conversion factor is necessary because there are usually multiple treasury bonds that are eligible for delivery into a futures contract, and they may have different coupons and maturities. The conversion factor allows for a fair comparison of the prices of different bonds, by converting them to a common standard. The conversion factor also ensures that the futures contract has a fixed notional value of $100,000, regardless of which bond is delivered.
For example, suppose that the cash price of a 10-year treasury bond with a 5% coupon is $98,000, and the futures price of a 10-year treasury bond futures contract is $99,000. The conversion factor for this bond is 0.9, which means that it has a lower coupon and a shorter maturity than the standard bond. The treasury bond basis for this bond is:
treasury bond basis = $98,000 - $99,000 x 0.9
treasury bond basis = -$1,100
This means that the bond is trading at a discount of $1,100 compared to its futures contract, or equivalently, that the implied repo rate for this bond is high.
The Delivery Options and the Cheapest-to-Deliver Bond
One of the key features of treasury bond futures contracts is that they allow for some flexibility in terms of which treasury bond can be delivered by the seller (or short position holder) to the buyer (or long position holder) at expiration. This flexibility gives rise to what are known as delivery options, which are essentially choices that the short position holder has when delivering a treasury bond.
The delivery options include:
The timing option: The short position holder can choose when to deliver the treasury bond within a specified delivery period, usually lasting for one month.
The quality option: The short position holder can choose which treasury bond to deliver among a range of eligible bonds, usually with different coupons and maturities.
The wild card option: The short position holder can choose to deliver the treasury bond on any business day after giving notice to the exchange by 8 p.m. on the previous day.
The end-of-month option: The short position holder can choose to deliver the treasury bond on either the last business day or the first business day of the following month.
The delivery options give an advantage to the short position holder, as they allow them to choose the most favorable delivery scenario based on market conditions. For example, if interest rates are rising, the short position holder can delay delivery until later in the delivery period, when the cash price of the treasury bond is likely to be lower. Alternatively, if interest rates are falling, the short position holder can deliver early in the delivery period, when the cash price of the treasury bond is likely to be higher.
The most important delivery option is the quality option, as it allows the short position holder to choose which treasury bond to deliver among a range of eligible bonds. The short position holder will naturally choose to deliver the cheapest-to-deliver (CTD) bond, which is the bond that minimizes their cost of delivering into the futures contract. The CTD bond is usually (but not always) the bond with the lowest coupon and/or shortest maturity among the eligible bonds, as it has the lowest cash price and conversion factor.
The CTD bond has a significant impact on the treasury bond basis, as it determines the implied repo rate and arbitrage opportunity between the cash and futures markets. If the CTD bond changes due to market movements or new issuance of treasury bonds, the treasury bond basis will also change accordingly. Therefore, it is essential for traders to monitor the CTD bond and its relative value to other eligible bonds.
The Factors that Influence the Treasury Bond Basis
The Benefits and Risks of Trading the Treasury Bond Basis
Trading the treasury bond basis can offer several benefits and risks for traders and investors, depending on their objectives and market views. Some of the benefits and risks are:
The Benefits of Trading the Treasury Bond Basis
Some of the benefits of trading the treasury bond basis are:
The opportunity to lock in a risk-free arbitrage profit: If the treasury bond basis is positive and higher than the financing cost of holding the bond, then a trader can buy the bond in the cash market and sell it in the futures market, and earn a risk-free profit at expiration. This is known as a cash-and-carry arbitrage. Conversely, if the treasury bond basis is negative and lower than the financing cost of holding the bond, then a trader can sell the bond in the cash market and buy it in the futures market, and earn a risk-free profit at expiration. This is known as a reverse cash-and-carry arbitrage.
The ability to hedge interest rate risk and duration risk: Investors who hold long-term bonds may use treasury bond futures to hedge against the risk of rising interest rates, which can decrease the value of their bond holdings. By selling treasury bond futures, they can lock in a fixed price for their bonds and reduce their exposure to interest rate movements. Similarly, investors who want to increase their exposure to long-term bonds may use treasury bond futures to hedge against the risk of falling interest rates, which can increase the value of their bond holdings. By buying treasury bond futures, they can secure a lower price for their bonds and increase their exposure to interest rate movements.
The flexibility to adjust exposure and duration using futures contracts: Traders who want to take advantage of interest rate movements or changes in the yield curve shape may use treasury bond futures to adjust their exposure and duration without buying or selling actual bonds. For example, if a trader expects interest rates to rise across the board, they can sell treasury bond futures to reduce their duration and exposure to interest rate risk. Alternatively, if a trader expects interest rates to fall across the board, they can buy treasury bond futures to increase their duration and exposure to interest rate risk. Moreover, if a trader expects interest rates to change differently for different maturities, they can use different treasury bond futures contracts to create a customized duration profile that matches their market view.
The Risks of Trading the Treasury Bond Basis
Some of the risks of trading the treasury bond basis are:
The possibility of basis widening or narrowing due to market movements: The treasury bond basis is not constant and can change due to various factors, such as supply and demand imbalances, interest rate fluctuations, volatility changes, liquidity conditions, new issuance of treasury bonds, or changes in the CTD bond. These factors can cause the treasury bond basis to widen or narrow unexpectedly, resulting in losses or gains for traders who hold basis positions. For example, if a trader buys a bond in the cash market and sells it in the futures market, expecting a positive basis to converge to zero at expiration, they may face losses if the basis widens instead due to an increase in demand for futures contracts or a decrease in demand for cash bonds.
The uncertainty of delivery timing and quality: The delivery options that give an advantage to the short position holder also create uncertainty for the long position holder, who does not know when or which treasury bond they will receive at expiration. This uncertainty can affect the value and liquidity of the long position holder's portfolio, as they may have to adjust their holdings or hedge their exposure accordingly. For example, if the long position holder expects to receive a high-coupon, long-maturity bond, but instead receives a low-coupon, short-maturity bond, they may face losses due to lower income and higher reinvestment risk.
The margin requirements and financing costs of holding a basis position: Trading the treasury bond basis involves holding both a cash position and a futures position, which require margin deposits and financing costs. The margin requirements and financing costs can vary depending on market conditions and leverage levels, and they can reduce or eliminate the potential profit from trading the basis. Moreover, if margin calls occur due to adverse price movements, traders may have to liquidate their positions at a loss or provide additional funds to maintain their positions.
Conclusion
The treasury bond basis is a key concept for anyone who is interested in trading or investing in treasury bonds and futures contracts, as it reflects the relative value and arbitrage opportunities between these two markets. The treasury bond basis is influenced by various factors, such as the delivery options, the CTD bond, the supply and demand of treasury bonds and futures contracts, the interest rate environment, and the volatility and liquidity of treasury bonds and futures markets.
Trading the treasury bond basis can offer several benefits and risks for traders and investors, depending on their objectives and market views. Some of the benefits include the opportunity to lock in a risk-free arbitrage profit, the ability to hedge interest rate risk and duration risk, and the flexibility to adjust exposure and duration using futures contracts. Some of the risks include the possibility of basis widening or narrowing due to market movements, the uncertainty of delivery timing and quality, and the margin requirements and financing costs of holding a basis position.

FAQs
Here are some frequently asked questions and answers about the treasury bond basis:
What is the difference between the gross basis and the net basis?
The gross basis is the difference between the cash price and the futures price of a treasury bond, without adjusting for the conversion factor. The net basis is the difference between the cash price and the futures price of a treasury bond, after adjusting for the conversion factor. The net basis is more accurate than the gross basis, as it reflects the actual cost or benefit of delivering a specific bond into a futures contract.
What is the difference between the implied repo rate and the actual repo rate?
The implied repo rate is the annualized interest rate that one can earn by buying a treasury bond in the cash market and selling it in the futures market (or vice versa). The actual repo rate is the annualized interest rate that one can earn by lending or borrowing a treasury bond in the repo market. The implied repo rate and the actual repo rate are usually close to each other, but they may diverge due to supply and demand imbalances, market frictions, or other factors.
What is a switch trade?
A switch trade is a type of bond swap that involves exchanging one treasury bond for another with different characteristics, such as coupon, maturity, or yield. A switch trade can be used to adjust exposure or duration, take advantage of relative value opportunities, or improve portfolio performance.
What is a TED spread?
A TED spread is a measure of credit risk in the economy, calculated as the difference between the interest rate on a 3-month Treasury bill and the interest rate on a 3-month Eurodollar futures contract. A high TED spread indicates that investors are demanding higher interest rates for lending money in the interbank market, which implies higher credit risk and lower liquidity. A low TED spread indicates that investors are demanding lower interest rates for lending money in the interbank market, which implies lower credit risk and higher liquidity.
What is a butterfly trade?
A butterfly trade is a type of yield curve trade that involves buying or selling three different treasury bonds or futures contracts with different maturities, such as 2-year, 5-year, and 10-year. A butterfly trade can be used to speculate on or hedge against changes in the shape of the yield curve, such as steepening, flattening, or twisting.
