Okay this is how I calculate :
Say capital 50,000.
I'm using the price history from March 1 03 to 16 Apr 08.
The lowest conversion rate is 0.35370, so if you convert you get 50000x0.35370 = 17,685 NZD
Now let's invert the exchange rates and look at the price history again.
The lowest conversion rate is 2.04420, so if you convert you get 17,685x2.04420 = 36,151.67 RM
So net loss = 50,000 - 36,151.67 = 13,848.33 (27.7%) or about 5.5% a year annualized.
Interest is 8.5% p.a so net interest is 8.5 - 5.5 = 3% p.a.
What am I doing wrong here ?

Friend, you are mess up on this case. The lowest 2.04420 is during 2003 time. Now is 2.50. So you only lose 25% if you are origin of NZD aka mean you convert your NZD to RM at 2003 and convert back to NZD at present time
For simple scenario,
On March 2003, if you have RM 50K, with the rate around 2003, let say you manage to convert it at 2.10 (2003 was traded and hovering around that price), you get NZD 23,809.
Then if you keep for 5 years. now with NZD rate at 2.50, if you convert back to RM, it will be 23,809 x 2.50 = 59,522.
So you gain RM9,552 on your RM50K
It is not taking of account of interest rate you gain during this 5 years.
Don't get me wrong, I am not promoting foreign currency FD, just to clarify the issue.

Go to oanda.com -- it's in the FX history section. Yours is not so valid because you randomly pick two days. Mine is a worst-case situation, you pick the two lowest conversion rates.
No wonder you lose on your calculation. He is valid also, as he doesn't pick extreme case or exchange rate. Exchange rate move is gradual over the time, it won't spike out and down quickly in one or two days time. Just like it takes years for NZD to go from 2.10 to 2.50.
Worst case scenario you mentioned is like I said before, you are a New Zealand person take NZD to convert to RM when 2003 time and keep for 5 years and convert back NZD at present time. So putting RM FD for the NZ person will yield as you mentioned, lose 25%. But not the other way round, for a Malaysian to put NZD FD.
Yes, you can lose out in Foreign currencies deposit if you put in wrong currency, like USD recent few year or just like I mentioned a New Zealand people put their NZD into RM.
So if one interested in foreign currency deposit, one needs to look at its currency strength and its economy status as currency movement is depended on the particular country economy strength.
So if one believes Malaysia economy is good with RM will appreciate against all major currencies then it is better to put as RM FD. As if it is the case, Foreign Currency deposit won't be good choice as you will lose out in the currency exchange.
But for the last few years, even though RM/USD from 3.60 to 3.15, RM is depreciating against most currencies.
So it is a place for one to diversify and protect against Rm depreciation but not a place to speculate to gain.
