Endowment Plan vs Treasury Bills (T-bills)

The one-sentence difference

A Singapore T-bill is a short-term government security, usually 6 months, with a yield fixed at auction and reset every fortnight for new buyers; a endowment plan is a multi-year insurance contract with a rate locked in for the life of the policy.

Timeline

T-bills mature in months, not years -- buy one, get your money and yield back quickly, and decide fresh each time whether to roll into the next auction. Endowment plans commonly run 5 to 25 years, with your rate locked in on day one for the whole term, for better or worse relative to where rates move afterward.

Return

A T-bill's yield is set at auction and known before you commit -- no ambiguity, no non-guaranteed component. An endowment's total illustrated return blends a guaranteed floor with a non-guaranteed bonus tied to the insurer's fund performance, so the number on the brochure isn't the number you're contractually owed.

Liquidity

T-bills can be sold on the secondary market before maturity if you need the cash sooner, though the price will move with prevailing rates. An endowment surrendered before maturity typically returns less than premiums paid, sometimes significantly less in the early years.

How to think about the choice

T-bills suit money you want parked safely for months at a time, reinvested at whatever the new rate is each cycle -- useful when you think rates might rise, or you just want short-term flexibility. An endowment plan suits a longer horizon where locking in a known guaranteed floor today, plus a shot at extra bonus, matters more to you than staying nimble on rates.

How often do T-bill rates change?

Singapore T-bill yields reset at every fortnightly auction, so the rate you get depends on when you buy -- unlike an endowment's guaranteed rate, which is fixed for the life of the policy.

Can I exit a T-bill or an endowment plan early?

A T-bill can be sold on the secondary market before maturity, though price will move with rates. An endowment surrendered early typically returns less than total premiums paid.

Which is more predictable, a T-bill or an endowment?

A T-bill's yield is locked in at purchase for its short term. An endowment's guaranteed portion is also fixed, but its illustrated total includes a non-guaranteed bonus that isn't.
