How to invest in a currency increasing in value relative to another?
On international stock exchanges, they trade Puts and Calls, typically also for currencies. If for example 1 NOK is worth 1 $ now, and you buy Calls for 10000 NOK at 1.05 $ each, and in a year the NOK is worth 1.20 $ (which is what you predict), you can execute the Call, meaning 'buying' the 10000 NOK for the contracted 1.05 $ and selling them for the market price of 1.20 $, netting you 12000 - 10500 = 1500 $. Converting those back to NOK would give you 1250 NOK. Considering that those Calls might cost you maybe 300 NOK, you made 950 NOK. Note that if your prediction is common knowledge, Calls will be appropriately priced (=expensive), and there is little to make on them. And note also that if you were wrong, your Calls are worth less than toilet paper, so you lost the complete 300 NOK you paid for them. [all numbers are completely made up, for illustration purposes] You can make the whole thing easier if you define the raise of the NOK against a specific currency, for example $ or EUR. If you can, you can instead buy Puts for that currency, and you save yourself converting the money twice.
