Currency swap: Contract that commits two counterparties to exchange streams of interest payments in different currencies for an agreed period of time and to exchange principal amounts in different currencies at a pre-agreed exchange rate at maturity.
A currency swap has three stages:
An initial exchange of principal: the two counterparties exchange principal amounts at an agreed exchange rate. This can be a notional exchange since its purpose is to establish the principal amounts as a reference point for the calculation of interest payments and the re-exchange of the principal amounts.
Exchange of interest payments on agreed dates based on outstanding principal amounts and agreed fixed interest rates.
- Re-exchange of the principal amounts at a predetermined exchange rate so the parties end up with their original currencies.
- Again this may be done to hedge risk, to speculate on changes in exchange rates, or to attempt to lower the cost of borrowing by borrowing in the currency in which the most favourable interest rates are available and then swapping into the currency that the firm needs to carry out its business. Whether this will be cheaper will depend among other things on the bid—offer spread.

A eurobond is a debt security handled internationally by syndicates, groups of bankers and/or brokers who underwrite and distribute new issues of securities or large blocks of outstanding issues. It is typically in bearer (non-registered form) and is issued outside the country of the currency in which it is denominated.
Borrowers and lenders are spread around the world, while the intermediaries are spread across Europe, with the majority of business being done from London. The market was founded in the early 1960s and has provided a competitive source of funding for borrowers who can tap discreet but important sources of finance. Japanese banks, pension funds and insurance companies have become important lenders in recent years and there are still plenty of wealthy individuals who prefer the anonymity offered by bearer securities. The eurobond market is the world’s second largest securities market after the US bond market in terms of trading volume and the third largest after the US and Japanese bond markets in terms of debt outstanding.

One issue that has elicited different responses is the role of currency risk in overall risk and return. Currency risk has been accounted for in all of the evidence presented. So the existence of currency risk will not reduce the benefits of investing in foreign markets. Rather, the question is whether managing currency risk will improve the gains from international investing.
While the reduction of any kind of risk is good, there are two issues that must be considered with regard to currency risk. First, the correlation between currency risk and stock market risk is close to zero. That means that currency changes and stock returns are independent of one another. Though both currency risk and stock market risk contribute to the total risk of a portfolio of foreign stocks, the contribution of currency risk to the total risk is not very large because of the zero correlation. On average, currency risk contributes less than 20 percent of the total risk. Read the rest of this entry »
Finally, the structure of the currency markets may work against elimination of the forward rate bias. Note that the forward rates depend only on the spot rate and the difference in interest rates. For arbitrage reasons, the forward rate cannot depend on anything else (see the discussion of interest rate parity in “Description,” above). However, an exchange rate between two currencies reflects the relative state of the two economies. If the U.S. economy is expected to do better than the Japanese economy, then the spot exchange rate will reflect that. Any changes in growth expectations will promptly cause a change in the spot exchange rate and thereby in the forward exchange rate. For example, the dollar strengthened from 1995 to 2000 because of the relative strength of the U.S. economy. During 2002 and early part of 2003, when expectations about U.S. economic growth were constantly revised downward, the dollar kept losing ground to other currencies. Read the rest of this entry »
There are several reasons for the persistence of the forward rate bias. Arbitrageurs or other smart traders may not be able to trade on the forward rate bias due to transaction costs and risk of taking positions. Second, arbitrageurs may be wary of the forward rate bias due to the absence of a logical explanation. Third, limits on arbitrage exist, as currency markets are very large. Finally, the forward rate bias will continue to persist probably due to the structure of currency markets. Each reason for persistence is discussed in turn.
There is general consensus based on the evidence presented above that the forward rate is biased and a poor predictor of the future spot rate. Read the rest of this entry »

Whatever the explanation for the forward rate bias and whatever the reason for its persistence, we hope that the forward rate bias will continue to exist well into the future. Armed with this evidence, how can tradable profits be realized? The easiest way to trade the forward rate bias is to use currency futures. Futures contracts can be easily bought or short-sold, are easy to cancel, and have low trading costs. On the other hand, forward contracts are restrictive and difficult to cancel. The pricing of forward contracts and futures contracts is almost identical, so the trading profits will also be equivalent. The trading strategy consists of buying the currency with the highest interest rate and unwinding the position a month later. A one-month holding period is chosen because the forward rate bias is most prominent for shorter periods. The following steps are taken in choosing and executing the strategy.
