Kirt C. Butler, Multinational Finance, South-Western College Publishing, 2e 3-8 Rule #1 Keep track of your units. An example: S $/FF = $.2500/FF  S FF/$ = 1/ S $/FF = FF4/$ Dollar value of a bottle of Georges de Bouef: Buy 1 bottle of wine P FF = FF40/btl Spot exchange rate S FF/$ = FF4/$ How much is this in dollars? P $ = P FF /S FF/$ = (FF40/btl)/(FF4.00/$)= $10/btl = P FF S $/FF = (FF40/btl)($.2500/FF)= $10/btl Example of what can go wrong: P $ = P FF S FF/$ = (FF40/btl)(FF4/$) = FF 2 160/(btl-$) ? No!

Rule #2: Always buy or sell the currency in the denominator of a foreign exchange quote. Example of buying low and selling high: Buy wine at FF40/btl and sell at FF50/btl  FF10/btl Profit Buy FFs at $.20/FF  Sell $s at FF5/$ Sell FFs at $.25/FF  Buy $s at FF4/$ $.05/FF ProfitFF1/$ Profit Example of what can go wrong: But... if you buy $s (and sell FFs) at $.2000/FF = FF5/$ and sell $s (and buy FFs) at $.2500/FF = FF4/$ you lose FF1/$ !!!

Kirt C. Butler, Multinational Finance, South-Western College Publishing, 2e 3-11 An example of forward premiums and discounts Suppose S  $/FF = $0.20/FF and F  $/FF = $0.25/FF Franc forward premium = ($.25/FF  $.20/FF)/($.20/FF) =  25% so the franc is selling at a 25% forward premium. Alternatively, S  FF/$ = FF5.00/$  S  $/FF = $0.20/FF F  FF/$ = FF4.00/$  F  $/FF = $0.25/FF Dollar forward premium = (FF4/$  FF5/$)/(FF5/$) =  20% so the dollar is selling at a 20% forward discount.

Butler, Multinational Finance, South-Western College Publishing, 2e 3-24 The Impact of News Events The Impact of News Events The U.S. Federal Reserve announces that in an effort to stimulate economic activity it is lowering the discount rate on overnight loans to commercial banks. This makes it easier for U.S. businesses to borrow and increases economic activity. If this also increases U.S. inflation, then the value of the U.S. dollar should fall. This will result in an appreciation of the ringgit against the dollar. Increases in the domestic discount rate usually, but not always, lead to increases in the value of the domestic currency.

Kirt C. Butler, Multinational Finance, South-Western College Publishing, 2e 3-25 The Impact of News Events The Impact of News Events The U.S. government reports that U.S. money supply M1 increased by $1 billion more than expected in the most recent quarter. While this would seem to result in a larger supply of dollars and hence a lower value for the dollar, the increase in the money supply has already occurred and hence should be reflected in the market price of the dollar. On the other hand, if the U.S. Federal Reserve is likely to react to this announcement by increasing the discount rate to slow down the economy, then the dollar may rise in anticipation of Fed policy. If the dollar rises against the ringgit, then the ringgit will fall against the dollar.
