A)	Given the bid-ask spread between pesos and dollars is 6.0000-6.0025, and the bid-ask spread between pounds and dollars is 2.0000-2.0015, then the bid/ask spread between pesos and pounds is 2.875-2.934.

B)	The bid-ask spread is a function of breadth, depth, and volatility of the market for a currency.

C)	A bid of 8.000 pesos/dollar, means the bank will sell you a dollar for 8 pesos.

When the bank bids they are buying and you are selling. Spot exchange rates, forward exchange rates, and interest rates are closely linked. The bid-ask spread between pesos and pounds is 6.0000/2.0015 = 2.9978 and 6.0025/2.0000 = 3.0013.

The gain or loss on a forward contract is unrelated to the spot rate. Gains or losses are measured relative to the forward contract rate, not the spot rate. Forward contracts call for delivery of a specified amount of a currency quoted against the dollar on a specific future date.

A)	Arbitrage is possible here, investors should borrow domestic, lend foreign.

B)	Arbitrage is possible here, investors should borrow foreign, lend domestic.

C)	The arbitrage possibilities cannot be determined with the data given.

Question 1: Is there an arbitrage opportunity?

If the result of the following formula (derived from rearranging the interest rate parity condition) is not equal to 0, there is an arbitrage opportunity.

(1 + r_domestic) ? [((1 + r_foreign) × Forward_DC/FC)) / Spot_DC/FC] = ?

Here, ( 1 + 0.10 ) ? [ (( 1 + 0.12 ) × 2.0_DC/FC ) / 1.9_DC/FC ] = ( 1.10 ? 1.18 ) = -0.08, which is not equal to 0. Arbitrage opportunities exist.

Question 2: Borrow Domestic (local) or Foreign? Here are some "rules" regarding where to start the arbitrage (where to borrow). These rules only work if there are no transaction costs and only if the currency is quoted in DC/FC terms.

Rule 1: If the sign on the result of question 1 is negative, borrow domestic. If the sign is positive, borrow foreign. Here, the sign is negative, so borrow domestic.

Rule 2: See table below.

(r_d ? r_f) < (Forward? Spot) / Spot Borrow Domestic

(r_d ? r_f) > (Forward? Spot) / Spot Borrow Foreign

Here, borrow domestic.

(r_d ? r_f) (Forward- Spot) / Spot

( 0.10 ? 0.12 ) ( 2.0_DC/FC ? 1.9_DC/FC ) / 1.9_DC/FC

-0.02 < 0.05

Summary: To take advantage of arbitrage

opportunities, borrow domestic and lend foreign.
