Why is basis negative

This difference in behaviour between two distinct groups of investors has left a gap between the CDS index and bond spreads. The difference between a CDS index and bond spreads can be split into two parts: the movement of indices relative to single name CDS, as measured by the skew; and the difference between single name CDS and bonds, as measured by the basis.

If we look at a chart of the skew, we can see that while it did exhibit a relatively large negative move, the minimum skew was bps, compared with bps for the basis.

The much smaller move in the skew we attribute to less liquid single name CDS being priced relative to the index, thereby limiting the extent to which the skew can move, and explaining why it is the basis that shows the majority of the move.

Repeating our analysis, this time splitting by rating, we see that similar directional moves are apparent in each ratings bucket, although the moves are exaggerated in lower-rated higher-beta names, as might be expected.

A key feature of a swap is that the parties do not transfer the ownership of the assets. There is no transaction of the underlying between the contract partners. So the con tract partners win flexibility and need less capital to fulfill the trade. An Asset Swap allows the investors to manage active duration of portfolios and the balance sheet and to trade credit spreads. The counterparty risk should be considered, which means that the contract partner cannot fulfill his obligations, as in all bilateral OTC contracts.

ABS are securities which consist of a pool of assets like credits, loans or bonds and which are secured by these assets.

In the case of CDOs the pool of assets are di vided in tranches which have different repayment priorities. By securitization loans and credits which are usually not available on the markets are made tradable. CDO products have to be separated in true sale transactions where the assets e.

The assets themselves stay in the ownership of the bank or former holder. These synthetic transactions can be supported by Credit Default Swaps see section 2. They can be funded or un funded. A funded synthetic CDO means that the investors pay an amount of money when the contract is fixed to secure for the default event.

A synthetic CDO can be regarded as an insurance contract on a pool or index of loans or bonds with a deductible and policy limit. The deductible and limit is con structed with the different tranches. With the investment in different tranches, the lev el of protection can be chosen: which part of the losses should be borne by the inves tor and which by the product.

The attachment point and the detachment point deter mine the border of protection and credit risk taking. Synthetic CDOs are very simple means to leverage the positions in the different tranches, because the capital struc ture is not predefined. In contrast to a true sale transaction the synthetic CDO con tract can theoretically be replicated in an endless way. It is possible to transact the underlying assets only one time, a synthetic transaction can in contrast be made as often as the seller wants.

True sale transaction or cash CDOs are no classical credit derivatives because the securitization process actually uses the real credits or loans. In this SPV several investors can invest their money in different tranches of bonds, cre dits or loans, which differ in their credit quality e. Like in a waterfall, the equity tranche would be touched first if the underlying defaults. After this, the different tranches up to the senior tranche would be touched.

In the true sale transaction a bank or financial institution can clear the balance sheet. Credit risk exposure which does not fit can be sold so that capital can be set free to use it for other loans, to improve the diversification of the loan portfolio or to lower the necessary equity quote of the balance sheet.

The bank or financial institution retains the equity tranche in most of the transactions to demonstrate the quality of the loans because the equity tranche is the first one to be touched if loans or bonds of the SPV default. If the bank was not convinced of the quality of the loans, it would not retain the tranche. This retaining reduces the asymmetric information problem between sel ler and buyer in the transaction. The bank knows much more about the credit portfo lio than an investor from outside of the bank or financial institution.

With CDO vehicles the investor can participate in risks he probably cannot take in his usual business or on the financial market. Imagine a bank which has a very regional and special loan portfolio: buying a tranche of a CDO can help to diversify the loan portfolio. Therefore, unsystematic risk can be reduced.

As a result the equity of the bank can be reduced or the lending can be increased. A problem in these contracts is the valuation of the several loans and tranches. Es pecially the correlations between the different probabilities of default are complicated to simulate and identify.

With the number of assets the complexity of the valuation is also growing. Rating Agencies assessed high ratings above A for these instruments in the whole pool of loans, although there were loans with lower ratings in the pool.

During the financial crisis it was not possible to eva luate the CDO accurately because there were almost no transactions in this time frame and the defaulted loans could not been evaluated or sold. So the liquid market of issuing and selling CDOs became very fast very illiquid for a first time. The default of many different loans in the pool also led to the default of technically safer and downstream tranches.

That actually means big losses for the owners of these tranches. The correlations of simultaneous defaulting were underestimated and the credit risk was not regarded adequately. Overall a synthetic CDO can be seen as a further possibility for the seller to transfer the credit risk to a tradable product.

Particularly the securitization and pooling of loans or bonds made this kind of products interesting for institutional investors and banks all over the world. The CDOs can be seen as one of the main financial instru ments of the financial crisis, because they consisted of the real estate loans which defaulted or lost a lot of value and so can be regarded as the trigger of the crisis.

Nevertheless CDOs are just instruments of trade, but they have to be evaluated by investors and rating agencies in the right way. From the view of the financial markets CDOs complete the market and make untradeable assets tradable. With Credit Spread Options the credit spread risk is tradable.

Credit Spread Options are compensated in case of a predefined credit event with a predefined payment. For this compensation a premium has to be paid during the lifetime of the option. It is typ ical for an option that it is possible for the buyer of the option to participate in changes of the underlying price during the lifetime of the option which is influenced by the creditworthiness. That means for example if the credit quality of the underlying is falling and consequently the credit spread becomes bigger, the value of the option will increase.

If the spread at maturity is bigger than the strike spread, the buyer will trigger the option. Therefore, the Credit Spread Options belong to the group of credit derivatives which only secure for credit spread changes, but not for the actual no minal of the underlying.

Nevertheless, if the underlying is nearly defaulted, the credit spread will also increase dramatically. The Credit Spread Option is not connected to the underlying capital. That means the credit risk can be traded separately from the nominal. The capital amount which is necessary is smaller than the transaction of buying the underlying and participating in the credit risk.

Speculation on credit risk or hedging the credit spread risk is possible in this category of credit derivatives as well. Compared to the described credit derivatives, Credit Default Swap CDS contracts only secure for the default of the underlying. The seller of the CDS receives the premium and secures at each point of time for the nominal of the loan or bond. The premium or CDS spread is quoted in basis points per annum of the notional amount of the un derlying.

Therefore, a CDS contract can be regarded as an insurance contract which is tradable. The premium for the original holder of the contract does not change over time and is calculated in advance. For an investor or buyer, CDS contracts mean to guarantee the transfer of the whole default risk. In contrast to interest rate swaps, the risk for the two participants in the contract is not symmetric.

Like options, the CDS contracts can imply a liability risk up to the whole nominal of the underlying for the seller. The buyer only takes the risk of losing all premiums paid in the lifetime of the contract if the un derlying does not default.

Even if he believes in a default of the underlying, he can stay invested in the bond or loan and receives a constant stream of interest payments. The CDS does not protect against changes in the credit spread and in the market value of the loan or bond during the lifetime of the contract.

A default of the underlying is mostly no surprise; it is a continuing development. The financial distress and the process leading to the default can be observed. This can be looked at in the credit spreads of the underlying and tracked with the new CDS premia. If the CDS contract is compared to products on the bond market or if a synthetic reproduction of the instrument is searched, following relationship holds:.

And vice versa algebraic signs for the CDS buy position. This relationship shows that the CDS spread or price could be seen as the credit spread of the underlying and make it possible to trade the default risk without buying and selling two securities si multaneously.

Therefore, CDS contracts complete the market for these investors. More advantages of the CDS contracts compared to other credit derivatives are the clear separation of credit and interest rate risk and the simple possibility to connect the contract with other products in a synthetic combination. It is also possible to ne gotiate about contracts with a completely different maturity than the underlying bond. Therefore, a CDS contract can only secure for the default of the reference entity for example for two years, when the bond has a maturity of 4 years.

Because of the separation of contract and underlying it is also possible to trade the contracts during the whole lifetime. For banks, which are typically net buyers of CDS, the contracts can lead to reduced equity requirements.

A negative basis means that the CDS spread is smaller than the bond spread. When a fixed-income trader or portfolio manager refers to spread, this represents the difference between the bid and ask price over the treasury yield curve treasuries are generally considered a riskless asset. For the bond portion of the CDS basis equation, this refers to a bond's nominal spread over similar-term treasuries, or possibly the Z-spread.

Because interest rates and bond prices are inversely related, a larger spread means the security is cheaper. Fixed-income participants refer to the CDS portion of a negative basis trade as synthetic because a CDS is a derivative and the bond portion as cash. So you might hear a fixed-income trader mention the difference in spread between synthetic and cash bonds when they are talking about negative basis opportunities. To capitalize on the difference in spreads between the cash market and the derivative market, the investor should buy the "cheap" asset and sell the "expensive" asset, consistent with the adage "buy low, sell high.

You can think of this as an equation:. It is assumed that at or near bond maturity, the negative basis will eventually narrow heading toward the natural value of zero.

As the basis narrows, the negative basis trade will become more profitable. The investor can buy back the expensive asset at a lower price and sell the cheap asset at a higher price, locking in a profit. The trade is usually done with bonds that are trading at par or at a discount, and a single-name CDS as opposed to an index CDS of a tenor equal to the maturity of the bond the tenor of a CDS is akin to maturity.

The cash bond is purchased, while simultaneously the synthetic single-name CDS is shorted. When you short a credit default swap, this means you have bought protection much like an insurance premium.

While this might seem counterintuitive, remember that buying protection means you have the right to sell the bond at par value to the seller of the protection in the event of default or another negative credit event. So, buying protection is equal to a short. While the basic structure of the negative basis trade is fairly simple, complications arise when trying to identify the most viable trade opportunity and when monitoring that trade for the best opportunity to take profits.
