Hi KC
Thanks for the invitation to the forum.
The macro look of monetary and fiscal policies affecting the currency rates in both countries, will lead to foreign exchange risk when one places in a dual currency deposit. There are also other intrinsic things to note about such plans.
In Singapore, the banks are very smart to package such plans as structure deposits or "dual currency fixed deposits". (not sure if it is the case in Malaysia). Dual Currency deposits are not simply fixed deposits in this case, as it is often options packaged in the plan. The bank protects its own risk by placing the liabilities to the public. If one eg. places his RM deposits in AUS money, and the currency in AUS falls to a certain rate, the bank will short or place the loss into the public's account, making a possible loss.
But of course if market situations is the countries are favourable, as some bankers would say on AUS or NZ, the returns would be good. All returns come at a risk involved. One may have to check if this also applies to Malaysia banks on such a product carefully.
