EXCLUSIVE: Why Your S$800k Bond Fund Feels Like “Peanuts” (And Why That’s a Trap)
2% Yield Edge = S$16k/yr. Don't Swap for 0.88% Fog
The 0.88% yield on your digital bank looks “safe” because the line never goes down, but your S$800,000 “Cash Empire” is currently being outpaced by a bond fund that most retail investors are too scared to hold because of a few “red” days. You aren’t losing money in the LionGlobal Short Duration Bond Fund (LGSDBF); you are witnessing the Optical Illusion of Accrual where short-term price wobbles hide a superior long-term income engine.

The Concept Deep Dive: Mark-to-Market vs. Linear Accrual
To understand why your statement reads “peanuts,” you must distinguish between an Escalator (Savings Account) and an Elevator (Bond Fund). MariBank is the escalator: it offers a linear base rate of 0.88% p.a. on all balances up to S$100k. You see a tiny tick upward every single day, which provides psychological comfort but offers zero protection against inflation or opportunity cost.
LGSDBF is the elevator. It operates on a Mark-to-Market (MTM) basis. The Net Asset Value (NAV) fluctuates daily based on the market price of its underlying bonds. As the provided data shows, the gross yield of LGSDBF declined from 3.18% in July 2025 to 2.59% in December 2025. To an amateur, a “declining yield” sounds bad. To the “Smart Money,” this is the sound of capital gains. When bond yields fall, bond prices rise.
