G-secs vs. Money market funds

Dear All,

I am looking to park a significant chunk of cash in either G-sec or Money market funds. Intent is to use the funds as cash margin while earning a little interest.

I would go for a G-sec but current prices are not competitive. Can someone advice on what is the advantage/disadvantage of G-secs over money market funds.

I can see the following advantages:

  • G-secs have much lower expense ratio
  • Minus expenses, G-secs still may offer better yield
  • G-secs will increase in value once the interest rates start going down. So principal appreciation possible.

Disadvantages:

  • Currently seems super expensive. Lower than expected yields
  • G-secs have lower liquidity compared to money market funds. This is of low priority as I am not looking to sell anything.
  • Money market funds have better tax treatment compared to G-secs that pay interest every six months
  • The margin on money market funds increases automatically as the fund gains in value. G-sec margin remains constant.

Please help me out. Where should I invest?

Best Regards,
Sandeep
