Call Bull Spread Bear Spread Calendar Spread Straddle Strangle Derivatives using Bloomberg 2 Functions in Bloomberg Two applications will be used in Bloomberg to evaluate derivatives: • SWPM <GO> Swap Manager SWPM is the main interest rate derivatives pricing function in the Bloomberg professional System, allowing users to price a wide range of vanilla and exotic interest rate swaps, interest rate options, swaptions and interest rate and hybrid structured notes. • OVME <GO> Options Valuation IMEF 2013 Bellia M. OVME is Bloomberg main pricing application for options on equity, indexes, funds, bonds, bond futures and short term interest rate futures. Derivatives using Bloomberg 3 Part I INTEREST RATE SWAP IMEF 2013 Bellia M. Derivatives using Bloomberg 4 Forward Rate Agreement A forward rate agreement (FRA) is an agreement that a certain rate will apply to a certain principal during a certain future time period • FRAs are infinitely flexible over-the-counter instruments (OTCs), as they can be structured to mature on any date. In general, FRAs are traded on the future level of 3 or 6 month Libor (Euribor). An FRA is an Off Balance Sheet instrument. IMEF 2013 Bellia M. Derivatives using Bloomberg 5 How to price a FRA FRAs can be valued in SWPM as: • a Spot start • IMM date (International Money Market) third Wednesday of March, June, September and December • Broken date (customized Start and end dates) Example: Suppose you enter in a FRA today, receiving a fixed rate for a 3month period, starting in 3 months. Principal: 1.000.000 € Rate: 0.18% Today: March 14, 2013 Effective: June 18, 2013 Maturity: Sept 18, 2013 IMEF 2013 Bellia M. Derivatives using Bloomberg 6 How to price a FRA Lender receives difference of 0.18% and reset rate in 3 Months IMEF 2013 Bellia M. Derivatives using Bloomberg 7 Plain vanilla Swaps A plain Vanilla interest rate swap is an agreement between two counterparties to exchange cash flows (Fixed vs. Float) in the same currency. The payments are made during the life of the swap in the frequency that was pre-established. In an interest rate swap the principal is not exchanged Used to convert a liability from – fixed rate to floating rate – floating rate to fixed rate With SWPM, one can configure many details of the deal, such as Dates, amortization scheme, start and end of a single payment… IMEF 2013 Bellia M. Derivatives using Bloomberg 8 Valuation of Swaps • The standard approach is to assume that forward rates will be realized • This works for plain vanilla interest rate and plain vanilla currency swaps, but does not necessarily work for non-standard swaps IMEF 2013 Bellia M. Derivatives using Bloomberg 9 How to price a plain vanilla Swaps Run SWPM EUR <GO> In order to display SWPM in EURO currency.

Derivatives using Bloomberg 14 Amortizing swap • Can be either Fixed-versus-Float or Float-versusFloat. • Both counterparties make interest payments that either are declining (amortizing) or accreting (increasing) over the life of the deal.

Derivatives using Bloomberg 17 Amortizing swap IMEF 2013 Bellia M. Derivatives using Bloomberg 18 Caps and Floors • A cap is a portfolio of call options on a reference interest rate (i.e EURIBOR or LIBOR). • It has the effect of guaranteeing that the interest rate in each of a number of future periods will not rise above a certain level • Each call is called “caplet”, so a cap is a portfolio of “caplets” • A floor is similarly a portfolio of put options. • For this (and others) derivatives, one of the input is the volatility, that can be choose between flat volatility (manual input) and VCUB volatilities. (VCUB is available hitting VCUB <GO>) IMEF 2013 Bellia M. Derivatives using Bloomberg 19 Caps and Floors Example: Notional 10.000.000,00€ Receive Fixed 0.577075% Pay Float rate EURIBOR 6M Contract starts March 18, 2013 Maturity is March 18, 2016 (3Y) Payments are quarterly (in advance) IMEF 2013 Bellia M.

Derivatives using Bloomberg 21 Caps and Floors In order to change from Cap to Floor, select the appropriate deal from the dropdown menu: IMEF 2013 Bellia M. Derivatives using Bloomberg 22 Digital options • An option whose payout is fixed after the underlying exceeds the predetermined threshold or strike price. It is also referred to as "binary" or "all-or-nothing option." A digital cap is a cap option that provides a payoff of specified coupon R% when strike K <= the floating rate. A digital floor is a floor option that provides a payoff of specified coupon R% when strike K >= the floating rate. • Digitals provide the buyer with a fixed payout profile. This means that the buyer receives the same payout irrespective of how far above or below the Index reaches in relation to the strike. • Digitals are cheaper to buy than standard options. IMEF 2013 Bellia M. Derivatives using Bloomberg 23 Digital options Digital cap IMEF 2013 Bellia M. 0.5% when strike 2% <= the floating rate. Derivatives using Bloomberg 24 Digital options Digital floor IMEF 2013 Bellia M. 0.5% when strike 2% >= the floating rate. Derivatives using Bloomberg 25 Dual Digital options • The receiver of this exotic payoff will obtain either of 2 alternative payoffs decided upfront. • The payoff to be received at each coupon date will depend from the level of the observation index immediately before the coupon payment date: a) b) If the index is above a pre-determined level (barrier), an “A)” payoff will be paid. If the index is below a pre-determined level, a “B)” payoff will be paid The two payoff can be either fixed rate, float rate, float rate minus (or plus) a spread. IMEF 2013 Bellia M. Derivatives using Bloomberg 26 Dual Digital options Example: • Notional 75.000,00€ • Barrier 0.5% • Reference rate: EURIBOR 6M • Contract starts March 18, 2013 • Maturity March 18, 2016 (3Y) • Payments are quarterly (in advance) Payoff a) If EUR6M >= Barrier b) If EUR6M < Barrier IMEF 2013 Bellia M.

Derivatives using Bloomberg 28 In Arrears Swap • Rate is observed at time ti and paid at time ti rather than time ti+1 • It is necessary to make a convexity adjustment to each forward rate underlying the swap • Suppose that Fi is the forward rate between time ti and ti+1 and i is its volatility • We should increase Fi by Fi 2 2 i (ti 1 ti )ti 1 Fi i when valuing a in-arrears swap IMEF 2013 Bellia M.
