If you think of the base currency (CHF, here) as a commodity (oil, say), then saying that the forward quote is a premium is saying that the forward price of oil is higher than the spot price of oil. Whether the quote is at a forward premium or a discount is the same as whether the base currency is trading at a forward premium or discount, respectively.
So they’re saying that the CHF is trading at a forward premium (vis-à-vis the CAD) and that the CAD is trading at a forward discount (vis-à-vis the CHF).
Yes I understand that the CAD is trading at a forward discount while the CHF is trading at a forward premium. Because in the future we will need more CAD to pay for the same amount of CHF.
But without specifying which is the base currency can we state if a forward quote is at premium or disocunt?
Or I should have assumed that in this example the CHF is the base currency (it is) and when we do not specify for which currency we want to determine if the quote is premium or discount we assume it is for the base currency?
So since the correct answer was: The forward quote is a premium (for the CHF) and the CAD is trading at a forward discount to the CHF.
And we don’t say the parenthesised part because it goes without saying?
Sorry for my complicated way of explaining myself.
