The Euro appreciates 5% versus the yen. The Peso depreciates 5% versus the Euro. What is the approximate appreciation or depreciation of the Yen/Peso exchange rate?
Answer>
Let x Euros can be bought by 1 Yen
Let y Pesos can be bought by 1 Euro
Let z Yens can be bought by 1 Peso
Now, The new Euro/yen exchange rate = 1.05x per yen
New Peso/Euro exchange rate = 0.95y per Euro
Also, we can approximate z as,
z = 1/x * 1/y = 1/xy
So approximate change in z when the new rates apply
z' = 1/(1.05x * 0.95y)
z' = 1/(0.9975xy)
so the change in new vs old exchange rate of Yen/Peso = z' / z
= 1/(0.9975) * (xy/xy)
= 1/0.9975
= 1.0025. Therefore percentage increase = 1.0025 - 1 = 0.0025 = 0.25%
Hence, The Yen/Peso exchange rate appreciates by 0.25% approximately.
