I’m not powayseller (obviously), but in my opinion for most people the most cost-effective way to get a Swiss franc position is probably to purchase a Swiss franc annuity. These annuities are quite liquid and pay a reasonable interest rate (for Swiss francs investments, anyway). They can also have favorable tax treatment when you start taking the money out if you actually “annuitize” your accumulated account at retirement.
Buying Swiss franc banknotes (i.e., “cash”) is possible, but you will probably find there is a pretty wide spread between the bank’s buying price and their selling price, which makes this a less desirable approach.
