My understanding so far...
It is about at anytime after dec5, not one year period.
According to item 51 in the FAQ, aggregate is rm1 mil for individual.
It means if u have rm500k loan outstanding, u r allowed to invest balance rm500k in foreign, whether local or abroad.
If u have rm1 mil or more in loan, not allowed at all.
But that is for new fx TOTAL from dec 5 onwards, what u already hv in fx now is fine.
No loan, free to do anything, local or abroad, anytime.
The motive behind is to stop individuals from borrowing in RM and put in FX.
In large nos., this can be very damaging, as seen in the tomyumgung crisis in 1997.
Actually, how it works is that as long as you have any form of MYR borrowings regardless of amount, you are subjected to that MYR 1 mio limit. It is not calculated anything like what you've mentioned.
Now I'm no expert when it comes to individuals (I handle corps instead), but I believe there are exceptions to what qualifies as MYR borrowings. Credit card might be excluded, as well as housing/car loans (first 2 of those loans I think). The loaded forumers here might be able to give more solid sharing.
