1. The first arbitrage opportunity relates to locational arbitrage. Holt has obtained spot rate quotations from two banks in Thailand: Minzu Bank and Sobat Bank both located in Bangkok. The bid and ask prices of Thai baht for each bank are displayed in the table below:

Determine whether the foreign exchange quotations are appropriate. If they are not appropriate, determine the profit you could generate by withdrawing $100,000 from Blades€™ checking account and engaging in arbitrage before the rates are adjusted.
2. Besides the bid and ask quotes for the Thai baht provided in the previous question, Minzu Bank has provided the following quotations for the U.S. dollar and the Japanese yen:

Determine whether the cross exchange rate between the Thai baht and Japanese yen is appropriate. If it is not appropriate, determine the profit you could generate for Blades by withdrawing $100,000 from Blades€™ checking account and engaging in triangular arbitrage before the rates are adjusted.
3. Ben Holt has obtained several forward contract quotations for the Thai baht to determine whether covered interest arbitrage may be possible. He was quoted a forward rate of $.0225 per Thai baht for a 90-day forward contract. The current spot rate is $.0227. Ninety-day interest rates available to Blades in the United States are 2 percent, while 90-day interest rates in Thailand are 3.75 percent (these rates are not annualized). Holt is aware that covered interest arbitrage, unlike locational and triangular arbitrage, requires an investment of funds. Thus, he would like to be able to estimate the dollar profit resulting from arbitrage over and above the dollar amount available on a 90-day U.S. deposit. Determine whether the forward rate is priced appropriately. If it is not priced appropriately, determine the profit you could generate for Blades by withdrawing $100,000 from Blades€™ checking account and engaging in covered interest arbitrage. Measure the profit as the excess amount above what you could generate by investing in the U.S. money market.
4. Why are arbitrage opportunities likely to disappear soon after they have been discovered? To illustrate your answer, assume that covered interest arbitrage involving the immediate purchase and forward sale of baht is possible. Discuss how the baht€™s spot and forward rates would adjust until covered interest arbitrage is no longer possible. What is the resulting equilibrium state called?

MINI CASE

Recall that Blades, a U.S. manufacturer of roller blades, has chosen Thailand as its primary export target for €œSpeedos,€ Blades€™ primary product. Moreover, Blades€™ primary customer in Thailand, Entertainment Products, has committed itself to purchase 180,000 Speedos annually for the next 3 years at a fixed price denominated in baht, Thailand€™s currency. Because of quality and cost considerations, Blades also imports some of the rubber and plastic components needed to manufacture Speedos.
