Hes right actually. I don't know the plan name, but my parents bought it not too long ago. Hold for 5 years and get back around 2.6% guaranteed. As long as you hold it for 5 years (or whatever amount of years you agree to, but minimum is 5 years). Only if you withdraw before the 5 years then you don't get back your full capital.
I guess very few people know about it because agents find it too troublesome for the little commission they are going to get from it (there was so much paperwork for the agent to do).
At first I also thought the same like some posters here, but as my parents were above 60 years old, the agent had to ask a closed family member to sit in to ensure that their money was not being cheated (see how troublesome it is for the agents). I was pretty surprised that such a plan existed and read carefully all the papers (you know some endowment have non-guaranteed and guaranteed amounts where the guaranteed amounts are much less than your capital put in, but for this, the capital amount is guaranteed as long as you hold it to maturity)
I try to look for the plan name tomorrow
