A dealer has PKR 100 million and receives the following rates of foreign exchange from the market. Find out how dealer can earn maximum arbitrage profit in FX market transaction. Solve and explain step by step.
Solution:-
Given,
A dealer has PKR = 100 million
Exchange rate:-
Now, there are two possible route to earn arbitrage profit:-
1st Route:-
a. Buy USD from 100 million PKR:
100 million PKR = (138/139)*100USD=99.28 USD
b. Buy GBP from 99.28 USD
99.28USD=(1.2729/1.2735)*99.28GBP=99.23 GBP
c. Buy PKR from 99.23 GBP
99.23GBP=(201/199)*99.23PKR=100.23PKR
Therefore arbitrage profit from 1st Route is (100.23-100)= .23 million PKR
2nd Route:-
a. Buy GBP from 100 million PKR:
100 million PKR = (199/201)*100USD=99.005 GBP
b. Buy USD from 99.005 GBP
99.005 GBP=(1.2735/1.2729)*99.005 USD=99.05 USD
c. Buy PKR from 99.05 USD
99.05 USD=(139/138)*99.05 PKR= 99.77 PKR
Here, no arbitrage profit from 2nd route.
Conclusion:
Arbitrage profit from 1st Route is possible to gain maximum arbitrage profit (100.23-100)= .23 million PKR
hence, follow the given step:
a. Buy USD from 100 million PKR
b. Buy GBP from USD
c. Buy PKR from GBP
