The time sensitive nature of markets also creates a pressurized environment. Each ZCB gives us a rate at which we can put money on deposit now for expiry at a specific time, and we can construct a discount curve from the collection of all ZCBs that we have available to us. Derivatives are special financial instruments that derive their value from one or more underlying assets.
Some designs constructed with a discount based methodology mean forecast -IBOR index rates are implied by the discount factors inherent to that curve:. During the life of the swap the same valuation technique is used, but since, over time, both the discounting factors and the forward rates change, the PV of the swap will deviate from its initial value. Therefore, the swap will be an asset to one party and a liability to the other. Swaps are marked to market by debt security traders to visualize their inventory at a certain time.
Interest rate swaps expose users to many different types of financial risk. Predominantly they expose the user to market risks. The value of an interest rate swap will change as market interest rates rise and fall. In market terminology this is often referred to as delta risk. Other specific types of market risk that interest rate swaps have exposure to are basis risks where various IBOR tenor indexes can deviate from one another and reset risks where the publication of specific tenor IBOR indexes are subject to daily fluctuation.
Interest rate swaps also exhibit gamma risk whereby their delta risk increases or decreases as market interest rates fluctuate. Uncollateralised interest rate swaps that are those executed bilaterally without a credit support annex CSA in place expose the trading counterparties to funding risks and credit risks.
Funding risks because the value of the swap might deviate to become so negative that it is unaffordable and cannot be funded. Credit risks because the respective counterparty, for whom the value of the swap is positive, will be concerned about the opposing counterparty defaulting on its obligations. Collateralised interest rate swaps expose the users to collateral risks. Depending upon the terms of the CSA, the type of posted collateral that is permitted might become more or less expensive due to other extraneous market movements.
Credit and funding risks still exist for collateralised trades but to a much lesser extent. Due to regulations set out in the Basel III Regulatory Frameworks trading interest rate derivatives commands a capital usage. Dependent upon their specific nature interest rate swaps might command more capital usage and this can deviate with market movements.
Thus capital risks are another concern for users. Reputation risks also exist. The mis-selling of swaps, over-exposure of municipalities to derivative contracts, and IBOR manipulation are examples of high-profile cases where trading interest rate swaps has led to a loss of reputation and fines by regulators. Hedging interest rate swaps can be complicated and relies on numerical processes of well designed risk models to suggest reliable benchmark trades that mitigate all market risks.
The other, aforementioned risks must be hedged using other systematic processes. The market-making of IRSs is an involved process involving multiple tasks; curve construction with reference to interbank markets, individual derivative contract pricing, risk management of credit, cash and capital.
The cross disciplines required include quantitative analysis and mathematical expertise, disciplined and organized approach towards profits and losses, and coherent psychological and subjective assessment of financial market information and price-taker analysis.
The time sensitive nature of markets also creates a pressurized environment. Many tools and techniques have been designed to improve efficiency of market-making in a drive to efficiency and consistency. In June the Audit Commission was tipped off by someone working on the swaps desk of Goldman Sachs that the London Borough of Hammersmith and Fulham had a massive exposure to interest rate swaps. When the commission contacted the council, the chief executive told them not to worry as "everybody knows that interest rates are going to fall"; the treasurer thought the interest rate swaps were a "nice little earner".

Since we can fix the price of the two legs exactly by arbitrage right now, we can value the swap by comparing the present value of each leg. As with FRAs, swaps are said to be at fair value when the values of the fixed and the floating rate match, and the overall value is zero.
This is the fixed rate at which we can enter a Swap for free, and occurs when such that. This is called the Swap Rate. It is fully determined by the discount curve, and as we shall see the reverse is also true — the Swap Rate is in 1-to-1 correspondence with discount curve. Of course, after a swap is issued the Swap Rate will change constantly, in which case the actual fixed payment will no longer match and the swap will have non-zero value.
If is the swap fixed coupon payment and is the current swap rate, then. Because of the number of institutions that want to handle interest rate risk resulting from loans, IR Swaps are one of the most liquidly traded financial products. This is a very important procedure, but financially rather trivial. As well as being important in their own right, FRAs and Swaps along with ZCBs, of course are the foundation of the rich field of interest rate derivatives. The right but not obligation to enter into an FRA — a call option on an FRA — is called a caplet, and a portfolio of such options on FRAs across different time periods is called a cap, since you have guaranteed a cap on the maximum interest you will have to pay over the whole period to borrow money a put on an FRA is called a floorlet, and a sequence of these forms a floor, for similar reasons.
