Your portfolio does not have a fixed term, the term is set flexibly according to your needs, nor does it have any type of linkage.
Your Savings Portfolio is NOT a deposit, it is better in the sense that it does not have a fixed term. This is because it is totally flexible. It does not have maturity. You can add money when it suits you, or withdraw it when you need to. All the money in your account will accumulate the advertised Yield with no strings attached.
