Funds Investing

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.

1. Re-exchange of the principal amounts at a predetermined exchange rate so the parties end up with their original currencies.
2. 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.

4. Structure of Currency Markets

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 »
