Suppose the Brazilian real is trading at 1 real = $.20 US, and the South African rand is trading at $.060 US. The value of one South African rand is ________ Brazilian real, assuming triangular arbitrage holds,
Answer :
1 Brazilian real = $0.20 US Dollar [Note : Given]
Or other way round, $1 US Dollar = (1/0.20) Brazilian real = 5 Brazilian real
1 South African rand = $0.060 US Dollar [Note : Given]
Or other way round, $1 US Dollar = (1/0.060) South African rand = 16.67 South African rand
If triangular arbitrage holds then :
5 Brazilian real = 16.67 South African rand
Thus 1 South African rand = (5/16.67) Brazilian real = 0.3 Brazilian real
Answer : The value of one South African rand is 0.3 Brazilian real, assuming triangular arbitrage holds.
