Keep cash positions in different currencies?
vabmit: One way that you can do this is through a retail stock broker, like TD Ameritrade, with CurrencyShares ETF's ( http://www.currencyshares.com/ ).I've done this with positions in the AUD and Swiss Franc.  Those two currencies tend to move in opposite directions since the Swiss Franc is a safety currency due to Switzerland being a relatively insulated mature modern economy.  AUD on the other hand, tends to be a growth play since Australia's economy is heavily based on the export of natural resources (think mining).  The two currencies tend to move in opposite directions increasing the likely hood that your wealth will be protected in most cases.  You can also use options to protect your positions on the ETF's.I keep 10% of my savings in foreign currency (via CurrencyShares) and 10% of my savings in precious metals (Gold & Platinum Coins (Philharmonics and Maple Leaves)).  The rest I keep either in a targeted retirement fund or my local currency (USD).Obviously, this portfolio hasn't worked out very well for me, recently. :(
