I have a 6.5% interest rate savings account I still have back home so I guess you can call that some form of investment. Definitely one that beats a 4% inflation rate. Our currency is also fixed against the US dollar. But I don't believe this is sustainable.
I also don't believe this is going to last more than a few more months until the bank has attracted as much cash as it needs. Of course that's also a third world middle eastern country and so lots can go wrong there which I have no control over. Thus my interest in moving it here. Vanguard is looking more interesting by the day. And yes, they do have a similar option.
