what is an interest rate collar 
an interest rate collar is a relatively low cost interest rate risk management strategy that uses derivatives to hedge an investor s exposure to interest rate fluctuations understanding interest rate collara collar is a broad group of options strategies that involve holding the underlying security and buying a protective put while simultaneously selling a covered call against the holding the premium received from writing the call pays for the purchase of the put option in addition the call caps the upside potential for appreciation of the underlying security s price but protects the hedger from any adverse movement in the value of the security a type of collar is the interest rate collar essentially an interest rate collar involves the simultaneous purchase of an interest rate cap and sale of an interest rate floor on the same index for the same maturity and notional principal amount an interest rate collar uses interest rate options contracts to protect a borrower against rising interest rates while also setting a floor on declining interest rates an interest rate collar can be an effective way of hedging interest rate risk associated with holding bonds with an interest rate collar the investor purchases an interest rate ceiling which is funded by the premium received from selling an interest rate floor remember that there is an inverse relationship between bond prices and interest rates interest rates fall as bond prices rise and vice versa the objective of the buyer of an interest rate collar is to protect against rising interest rates purchasing an interest rate cap i e a bond put option or rates call option can guarantee a maximum decline in the bond s value although an interest rate floor bond call option or rates put option limits the potential appreciation of a bond given a decrease in rates it provides upfront cash and generates premium income that pays for the cost of the ceiling let s say an investor enters a collar by purchasing a ceiling with a strike rate of 10 and sells a floor at 8 whenever the interest rate is above 10 the investor will receive a payment from the seller of the ceiling if the interest rate drops below 8 which is below the floor the investor who is short the call must now make a payment to the party that purchased the floor clearly the interest rate collar strategy protects the investor by capping the maximum interest rate paid at the collar s ceiling but sacrifices the profitability of interest rate drops interest rate caps and floorsan interest rate cap establishes a ceiling on interest payments it is simply a series of call options on a floating interest rate index usually 3 or 6 month london inter bank offered rate libor which coincides with the rollover dates on the borrower s floating liabilities the strike price or strike rate of these options represent the maximum interest rate payable by the purchaser of the cap an interest rate floor is the minimum interest rate that is created using put options it reduces the risk to the party receiving the interest payments since the coupon payment each period will be no less than a certain floor rate or strike rate reverse interest rate collara reverse interest rate collar protects a lender e g a bank against declining interest rates which would cause a variable rate lender to receive less interest income if rates decline it involves the simultaneous purchase or long of an interest rate floor and sale or short of an interest rate cap the premium received from the short cap partly offsets the premium paid for the long floor the long floor receives a payment when the interest rate falls below the floor exercise rate the short cap makes payments when the interest rate exceeds the cap exercise rate
