Interest Rate Futures July 2011
Introduction • Interest rate Futures • Short term interest rate futures (STIR) • Long term interest rate futures (LTIR)
2010 Break down of interest rate contract volume by product group
Principle value of 1 Mil with a three-month maturity • Quote : 100 - yield • yield = (discount/price)(360/day to maturity) • price = 1 mil – discount yield(%)*1 Mil*DTM • 360
Short term interest rate futures • Eurodollar • Assume discount yield is 8.32 % with 90 days to maturity what is the price? • price = 1 mil – discount yield(%)*1 Mil*DTM 360 • Price = 1,000,000 - [(.0832*1,000,000*90 )/360] • = 979,200 • Quotation = 100-.0832 = 91.68
Pricing futures • Cost of carry model in perfect market • market is perfect • financing cost is the only carrying charge • ignore the different between forward and futures prices • ignore the options the seller may possess
Interest rate futures and arbitrage 10% Jan 5 167 days Mar 22 77 days 90 days 6% 12.5%
Interest rate futures and arbitrage Jan 5 10% Mar 22 167 days 77 days 90 days 8% 12.5%
Interest rate futures and arbitrage • For no arbitrage to happen: • Holding 167 days t-bill(10%) must give equal yield to hold 77 days t-bill followed by 90days t-bill (12.5%) from futures delivery • Only yield that prevent arbitrage is • 953611 = 968750-(96850*(x)*(77/360)) • 953611/968750 = 1-(.213889x) • X = .73063
Financing cost and implied repo rate 1+C = 968,750/953611 = 1.015875

The futures yield and forward rate of interest 1.048646 953,611 1,000,000 10% • 1.048646 = x * 1.015875 • X = 1.032259 ; forward rate =3.2559% 167 days 77 days 90 days 953,611 7.3063% 968,750 12.5% 1.015875
Longer maturity interest rate futures • Treasury bond Futures • Treasury Note futures
Delivery of Bond futures • Majority of position will be liquidated or rolled forward and only tiny amount resulted in delivery
Deliverable grade • Deliverable grade is defined in contract specification and is varied by contract. • Several bonds could be delivered against the contract. Seller will choose the cheapest to deliver bond to deliver. • Conversion factors will adjust for the differences in coupons and maturity among the deliverable bonds. (approximate from assume face value of bond is 1$ and discounted the CF from bond at 6% using bond pricing equation) • When delivery , invoice piece will equal converted futures price + accrued interest • converted futures price = contract scale factor (1000)* settlement price *conversion factors
Invoice price If accrued interest is 519.71
The cost of carry model for T-bond futures Cash and carry arbitrage for a T-bond • T-bond that is deliverable on a futures contract has an 8% coupon and cost 100$. • Financing rate 7.3063% on a discount basis for 77 days until futures contract is deliverable. Assume perfect market no seller options
Speculating with interest rate futures • Outright position • Long trader: betting interest rate will fall and futures prices will rise • Short trader: betting interest rate will rise and futures prices will fall Example : Trader Expect short term interest rate will rise.
Speculating with interest rate futures • Spread position • Intra-commodity : speculate on the term structures of interest • Example : Trader expects that the current very steep upward sloping yield curve would flatten within six month. (not sure whether rates were going to rise or fall. .
Speculating with interest rate futures • Spread position • Inter-commodity : speculate on shifting risk level between instrument • Example : International debt crisis, bank involved in international lending has more risk. May expect to find a widening of yield spread between T-bill and Eurodollar deposit. .
