Also there are some structured products available at some of the banks (I know HSBC has, also many of the Chinese banks). These offer a better yields than CDs, but are tied to some kind of commodity index or equities so do involve additional risk obviously. Many are principal guaranteed so the downside is at least limited.
Depends on how long you want to tie up your funds – but if fairly short term, your safest option is probably the boring 3 mo bank CD (which is regulated, so every bank offers exact same rate).
But if you have over $3 mil USD equiv, which I doubt since you are seeking financial advice on this site, you would have a few more options…..
