Thanks for the replies.
Like I mentioned, I'm very new to MMF. If you ask me, I think barely know about the implication of OPR.
Tried my best to understand the concept, but it's still very abstract to me.
I'm not a professional in finance, economy, you see. The product fact-sheet is filled with finance-jargons. That's why I am asking.
Thanks to you, I manage to know that MMF allocation consists of interest-imposed products available in bank.
Btw,
what's TIA?

My search results are not helpful at all.
And it seems that the amount of returns from those products was determined by OPR, I presume.
May I know if all the following products/instruments depending on OPR as well?
Asset allocation: Primarily in government / government-backed securities, bills of exchange, negotiable certificate of deposits, promissory notes,
call deposits and other short-term government/ bank-backed securities and money market instruments. Section Allocation as at 31st Dec 2020:
100% Cash, The Fund invest in Short-term Money Market Instruments and Placement in Short-term Deposit onlyMay I know what's the significance of different weightage of cash/bond in a MMF product?
