the 25,000 RM limit
In my country (Romania) such limit exists for some years now. Just iirc it's about 10000 EUR / cash transaction, so 45000 RM.
And I can tell that I know only 2 cases average Joe faces these limits: when selling/buying a home (house, apartment) or a (new) car, which operations usually happen through bank / credit anyway.
So I think that it's not a real / big problem.I agree. It can be a problem for high-end criminals and corrupt officials, but for regular people it can't be. In fact, common people can benefit from the restriction, because, instead of being stolen and laundered, money will flow in the right direction: to public schools, state hospitals, etc.
As for the legit firms in Malaysia, who regularly, each day, buy goods and services with the amounts that surpass the 25,000 RM($6,000 USD) limit, I don't think they usually pay with cash for something priced over that limit.
Well, maybe for lower class people it's not too problematic but this will be a problem for private companies or those who have businesses. Surely their business will be hampered by transaction limits that are too low, although not all of them do cash transactions but it will be complicated when having to make transactions.
Maybe it is better for banks in Malaysia to provide special bank accounts for companies to more freely run their business without having to be hampered by this regulation.
