Given the following midpoint spot exchange rates: USD/EUR 0.9119, CHF/USD 1.5971, and USD/JPY 128.17, calculate all of the cross-exchange rates.
Given:
There are 4 currencies, hence using permutations and combinations, there will be following combinations
USD/x | Formula | Value |
EUR | Given | 0.9119 |
JPY | Given | 128.17 |
CHF | 1/(CHF/USD) | 0.626 |
Let me explain this. Take the third row: USD/CHF:?
We are given the value of CHF/USD. Hence, we can find the value of USD/CHF, by taking the reciprocal of CHF/USD.
Proceeding to next table:
CHF/x | Formula | Value |
USD | Given | 1.5971 |
JPY | (CHF/USD)*(USD/JPY) | 204.7003 |
EUR | (CHF/USD)*(USD/EUR) | 1.456395 |
Consider second row. We need to find: CHF/JPY
Now, consider this formula: (CHF/x)*(x/JPY): We need to take the value of x such that we already possess the values of the terms: (CHF/x) and (x/JPY)
Hence, x can be USD. Putting (CHF/USD) = 1.5971 and (USD/JPY) = 128.17, we get CHF/JPY = 204.70
EUR/x | Formula | Value |
USD | 1/(USD/EUR) | 1.0966 |
JPY | (EUR/USD)*(USD/JPY) | 140.5512 |
CHF | (EUR/USD)*(USD/CHF) | 0.686472 |
JPY/x | Formula | Value |
USD | 1/(USD/JPY) | 0.007802 |
EUR | (JPY/USD)*(USD/EUR) | 0.007115 |
CHF | (JPY/USD)*(USD/CHF) | 0.004884 |
