Ways of expressing forward rates

In addition to the direct or indirect quotation, forward exchange rates can be expressed in one of three ways. First, the forward rate can be quoted as an outright rate — i.e. the actual forward rate of exchange.

Secondly, it can be quoted as forward exchange margins or points (also called swap rates). These latter are either discounts or premiums depending on the interest differentials between the home and foreign currency. If the foreign currency interest rate is higher than the home currency interest rate, the foreign currency will be at a forward discount to its spot rate. If, on the other hand, the foreign interest rate is below the home currency interest rate, the foreign currency will be at a forward premium to its spot value. The magnitude of the discount or premium is dependent upon the size of the differential in home and foreign interest rates and the time to maturity of the forward contract. Read more »

The Black model should not be used for valuing American options on currency futures because it may be optimal to exercise the options early in the same way as it may be optimal to exercise options on the spot currency early. The binomial or the Barone-Adesi and Whaley models may be used for valuing those options.

The early exercise potential of American options on futures is different to that of options on the spot. Futures prices do not exhibit the discrete jumps that accompany spot market assets when the underlying spot asset makes discrete distributions. However, as the carry basis of the future converges to zero at delivery, the futures price converges to the spot price in an orderly manner. Read more »

As with all other forms of futures contract, the fair price of short-term interest rate futures should preclude any arbitrage possibilities between the futures market and the underlying cash market. In the case of bank deposit interest rate futures, there should be no arbitrage possibilities between the forward interest rate implied by the future and the forward interest rate available on the appropriate type of bank deposit. For example, a three-month eurodollar futures contract that has 135 days to maturity should not provide any arbitrage possibility with the 135-day forward rate on a three-month eurodollar deposit.

It was shown that it is possible to lock in a forward rate of interest. However, depositors will only lock in a forward deposit if the rate that results is at least as favourable as the rate that they expect to prevail at the future point in time. If the forward rate implied by the current rates was above investors’ expectations, theinvestors would increase their borrowing for 90 days, causing upward pressure on that rate, and increase their deposits for 180 days, causing downward pressure on that rate, thereby bringing the 90-day forward rate down to current expected levels.

Conversely, if the implied forward rate were below expectations, investors would borrow for the longer term, raising that rate, and deposit for the shorter term, lowering that rate, until the implied forward rate matched expectations. Read more »

As the name implies, an FRA is an agreement to buy or sell a forward rate of interest on a notional principal amount. Remembering that interbank deposit rate futures also relate to forward rates of interest, the similarity between the two instruments will be obvious. Conceptually, the seller of the FRA undertakes to provide an agreed rate of interest on a notional deposit of a specified size at a previously agreed future date. Thus the FRA locks in the rate of interest on a forward deposit, the forward rate of interest.

An FRA relating to the interest rate on a six-month deposit starting in three months time is referred to in FRA market parlance as a 3 against 9 (or a 3 vs 9) FRA. This clearly indicates that, in this example, the appropriate interest rate is the six- month forward rate three months hence. Read more »

The valuation of interest rate options is currently the most contested area of option- pricing theory. The problem stems from the fact that although there is a reasonable consensus about the nature of the stochastic process of share prices, equity indices and currencies, the movements in interest rates and interest rate dependent instruments are not fully understood and full agreement on the underlying process has yet to be reached.

The stochastic process of interest rates, and therefore the prices of interest rate dependent claims, has proved to be very difficult to model for a number of reasons. Read more »

Bonds are frequently purchased to fund future liabilities because of the relative certainty of the cash flows which are set contractually. However, the certainty as to the value of the terminal value of those future cash flows depends upon two factors:

the rate at which the future coupons can be reinvested remaining unchanged;

if the bond has a maturity longer than the desired holding period, the level of interest rates is the same at the beginning and end of the holding period. Read more »

Term structure based option-pricing models

Term structure models of pricing contingent claims have followed one of two approaches. One approach followed by Cox, Ingersoll and Ross (1985) actually model the expected returns from movements in the term structure in order to price the contingent claims. In effect, the term structure becomes endogenous to the pricing of the contingent claim.

The second approach followed by Ho and Lee (1986), Heath, Jarrow and Morton (1989), Black, Derman and Toy (1990) and Hull and White (1990) utilizes the volatilities of the various sectors of the term structure to derive a probability distribution of an arbitrage-free binomial, trinomial or multinomial lattice of the term structure. From this lattice, contingent claims are priced. These models all have one thing in common: they allow for the whole-term structure to be stochastic instead of the price of a single underlying instrument or a single interest rate. The whole-term structure is represented at each node of the binomial, trinomial or even multinomiaf lattice. Read more »

A detailed analysis of the empirical testing of the term structure is beyond the scope of this post; however, in summary it should be stated that the empirical tests give a substantial role to expectations. However, forward rates are not unbiased estimators of future spot rates, and the bias is consistent with a liquidity premium. There is also some evidence that the premium increases with the term to maturity, but at a decreasing rate. There is less support for the segmentation hypothesis.

The dynamics of the term structure

Clearly the term structure is dynamic, but exactly what is the nature of this dynamic process? It has long been observed that long rates are less volatile than short rates; for further discussion see Kessel (1965), Malkiel (1966) and Brooks and Livingston (1990). Current long-rate volatilities are linked to current short-rate volatilities by the concept of mean reversion — i.e. where short rates have a tendency to be pulled back towards some long-term average value following a movement up or down.

Bonds with equity warrants attached

Recently it has been popular among Japanese corporations to issue eurobonds with equity warrants attached. Their popularity has stemmed partly from the strength of the Tokyo stock market, the warrants giving an equity kicker to bond investors.

These warrants are usually detached from the bonds after issue, and traded separately. Bonds with warrants attached are different from convertible bonds because the warrants are long-term options which when exercised require new cash, not existing bonds, to be exchanged for the new equity. At the time of issue, the bonds constitute a portfolio consisting of one bond and one long-term option on the equity of the issuer. After the time of issue, and when the warrants have been stripped, the bonds are valued as straight bonds. Read more »
