or just do not be so 'honest'

yes agreed. Only yourself responsible for your own investment decisions. However should not let paying loans deny you from investing

I've spoke to the customer care earlier. These are excerpts of the explanation:

"As StashAway invests your money in foreign currency assets, we will have to comply with Notice 3 of the Foreign Exchange Administration Rules and we are unable to proceed with your account opening on StashAway’s Malaysia platform at this moment."

"At this moment, we can only proceed with client who owned not more than ONE House loan and not more than ONE Vehicle loan."

The Foreign Exchange Administration (FEA) Rules are found on Bank Negara website:

It’s just StashAway covering their own ass. If people wanna be dishonest, it’s not SA’s fault at least.

stash away is still small, if the fund size become ubber huge. BNM might want them to perform CTOS or CRISS check not like some lame questionnaire haha....  just like cypto, at first BNM dont even bother. until it get hot, BNM steps in and require all crypto site to comply if KYC.
