Trading Case FX3
To understand no arbitrage relationships among exchange rates (spot and forward), interest rates (domestic and foreign) and currencies in terms of triangular arbitrage.
Arbitrage free relationships, covered interest rate parity, triangular arbitrage, spot and forward exchange rates.
In this trading case you will trade in a mixed currency environment containing $USD, $AUD and EUR. You can have long or short positions in the securities traded, and different traders may have different positions. There are eight markets open that you can submit market and or limit orders to during the first trading day of a calendar year. At the end of this day time “jumps forward” and your position is marked to market in $USD using the realized end of year exchange rates. Both short sales and borrowing is permitted in all currencies and at the end of the year your position earns/pays any accrued interest resulting from your day 1 trading activities.
Opening Trading Screen
The opening screen appears as follows. The markets are described below.
Market 1 is “usdzero.” This market trades a zero coupon bond that pays $USD100 at the end of the year. Market 2 is a zero coupon bond, “audzero,” that pays at year end $AUD100. Market 3 is forward exchange rate market, “fwdaud,” that trades $AUD per 1 unit. That is, a limit order of 0.60/1 if hit implies that at the end of the year the bidder pays $USD0.6 to receive $AUD1. If the realized end of year exchange rate is 0.75 then the bidder pays $USD0.6 and receives $AUD1 which has a marked value of $USD0.75 per unit. As a result, the realized gain from this forward exchange rate transaction for 1 contract equals $USD0.15. If 10,000 units had been traded at this price the realized gain equals USD$1,500. Market 4 (audusd) is a spot exchange rate market. It is quoted in units of $USD per 1 $AUD. That is, a bid of 0.60/1 is a limit order that is offering to pay $USD0.60 for $AUD1. Traders can trade up to 10,000 dollars at a time (a click of the mouse). Market 5 is a euro zero coupon bond, “eurzero,” that pays at year end EUR100. Market 6 is forward exchange rate market, “fwdeur,” that trades EUR per 1 unit. That is, a limit order of 1.25/1 if hit implies that at the end of the year the bidder pays $USD 1.25 to receive EUR1. If the realized end of year exchange rate is 1.5 then the bidder pays $USD1.25 and receives EUR1 which has a marked value of $USD1.5 per unit. As a result, the realized gain from this forward exchange rate transaction for 1 contract equals $USD0.25. If 10,000 units had been traded at this price the realized gain equals USD$2,500. Market 7 (eurusd) is a spot exchange rate market. It is quoted in units of $USD per 1 EUR. That is, a bid of 1.30/1 is a limit order that is offering to pay $USD1.3 for EUR1. Traders can trade up to 10,000 dollars at a time (a click of the mouse). Finally, market 8 is a spot exchange rate market that trades euraud. A bid of 2/1 in this market is bidding $AUD2 for 1 EUR. The screen below illustrates the markets open.
are three money markets in this case.
The first is your Cash account (see Cash: in the above screen with a
balance equal to 200000). This is
your current cash balance in USD.
The second, is the balance under Position beside audusd (balance equals 0
in the above example). This is your
current balance of cash in units of AUD.
The third, is the balance under Position beside eurusd (balance equals
200000 in the above example) and/or your balance in euraud. These accounts
represent your current balances in euros.
The third, is the balance under Position beside eurusd (balance equals 200000 in the above example) and/or your balance in euraud. These accounts represent your current balances in euros.You can borrow or lend directly to each of the money markets at the rate of interest that applies to each currency. This is 0.0291 per annum (compounded annually) for the USD, 0.0463 per annum (compounded annually) for the AUD, and finally 0.0326 per annum for the Euro.
Each market is open for day 1 of the year. As a result, a long position in either money market at the end of the trading day accrues interest for the year. Similarly, a short position in either cash account, at the end of the trading day, pays the interest that accrues for the year. During the trading day balance fluctuations in either cash account do not attract interest accruals or payments.
The set of possible realizations for the end of year cost of $AUD in units of $USD depends upon the path each economy follows throughout the year. In this case the possible exchange rate realizations for audusd lies in the following interval: [0.53, 0.80]. That is, the realized exchange rate is any number between 0.53 and 0.80 with each possible realization being equally likely. Similarly, the possible realizations for the eurusd lies in the interval [1, 1.5]. Again each realization is equally likely. It is your task as part of the trading crowd to discover a price for the spot exchange rates plus the cross rate for the first day's trading.
Your aim is to make as much money as you can which depends upon how well you trade relative to the prices discovered by the market.
