Where to Park Your Cash for Higher Yield: T-Bills vs Fixed Deposits vs SSB (Updated for 1.92% T-Bill Yields)

Today's long-form is the ⭐ Members Edition, made free for everyone.

The Numbers

The 6-month T-bill just cleared at 1.92%, its highest print this year. Most fixed deposits are still under 1.70%. CPF OA pays 2.5% for October to December 2026, but that money cannot be touched in an emergency. At S$100,000, DBS balance bands can cut the effective FD rate on anything above S$20,000. Syfe Cash+ Enhanced shows a 3.0% projected return, but the data behind it is dated 17 November 2025, so I treat that figure as stale.(Correct me here if you have updated data, so that we can share with the community).

My Personal Take

My first reaction to 1.92% was to compare it with the fixed deposit rates I keep seeing advertised. What I almost missed is that the headline rate is not what decides this. Your balance band and how soon you might need the cash do. It took me a while to connect the CPF OA 2.5% to the T-bill number, because they answer different questions: one pays more but is locked, the other pays less but you can reach it. That split between cash you may need soon and cash you can leave alone is where the full piece spends its time. Let the numbers speak, kopi-o in hand. 🦖
