Complete Overview of Singapore Savings Bonds in 2025

Singapore Savings Bonds (SSBs) are fully backed by the government, non-tradable securities designed for retail investors. Each bond pays interest every six months, with rates that step up over the 10-year tenure. The May 2025 issue (SBMAY25) offered a first-year rate of 2.66% and a 10-year average return of 2.78%. You can invest as little as S$500, and the maximum individual holding is S$200,000. This structure makes SSBs a benchmark instrument for risk-free income generation within a portfolio.

How the Step-Up Interest Works

Interest rates are preset and published before each monthly issuance. The schedule increases each year, so you earn more for holding longer. In the May 2025 tranche, the year-1 payout was 2.66%, year-2 rose to 2.69%, and year-10 reached 3.05%. The average annual return smooths out these jumps to 2.78%. If you redeem early, you receive accrued interest without penalty, which means you capture the lower near-term rates and forfeit the higher later-year yields. The design encourages buy-and-hold behavior while still offering full liquidity.

2025 SSB Rates in Context

Since January 2025, the 10-year average yield has fluctuated between 2.72% and 2.89%, according to MAS issuance data. The April 2025 bond recorded 2.77%, while February’s hit a local peak of 2.88%. This compares with 3.26% in June 2024—a reflection of the easing cycle. Despite the compression, SSB rates remain above the 10-year historical median of 2.45% (2015–2025). The current spread over CPF Ordinary Account’s 2.5% floor makes SSBs a viable option for cash holdings outside the CPF system. Allocation limits of S$200,000 cap the total return potential but maintain accessibility.

Building a Bond Ladder for Regular Income

A ladder spreads capital across several SSB issues to create a recurring cash flow. Purchase five S$20,000 tranches in consecutive months: January, February, March, April, and May 2025. Each bond pays interest semi-annually starting from its issue month, so you receive payments roughly every month. For example, the January bond pays interest in January and July. By May, you have monthly payouts from different bonds. Using the average 2.78% yield, the combined S$100,000 portfolio generates about S$2,780 annually, or S$232 monthly. Reinvesting the proceeds into new issues compounds the ladder automatically.

SSBs vs T-bills and Fixed Deposits

6-month T-bills in May 2025 yielded approximately 2.55% (MAS auction data), while 12-month bank fixed deposits hovered around 2.80–3.00% for promotional rates. SSBs offer the advantage of locking in the yield curve without reinvestment risk. A 6-month T-bill rolled four times in two years might suffer from falling rates; an SSB held for two years with its step-up schedule already guarantees 2.69% in year two. For an investor who needs liquidity after 3 years, SSBs outperform a 2.80% fixed deposit that imposes early withdrawal penalties, as SSB redemption returns full principal plus accrued interest.

Tax Efficiency and Liquidity Mechanics

SSB interest is tax-exempt for individuals in Singapore. There are no capital gains taxes, and redemption proceeds land in your bank account by the next business day. The S$2 transaction fee per redemption request is negligible. Because the bonds are not tradable, their capital value does not fluctuate, eliminating mark-to-market losses. You can redeem in multiples of S$500, leaving the rest intact. This precision lets you tailor cash flows exactly—redeem S$1,000 to cover a bill while keeping the remaining S$19,000 earning the higher year-5 rate.

FAQ

Q: What is the current SSB interest rate for a 1-year holding period?
A: The May 2025 SSB pays 2.66% for the first year. If you redeem after exactly 12 months, you will have received two semi-annual interest payments totaling 2.66% of your principal, plus the full principal back. No penalty applies.

Q: How much can I invest in SSBs across multiple issues?
A: The overall individual limit is S$200,000. You can hold up to S$200,000 per person across all outstanding SSB issues combined. For a couple, the combined household limit is S$400,000. Each monthly application can be up to the remaining balance below this cap.

Q: Can SSB interest rates change after I buy?
A: No. The step-up schedule is fixed at issuance. If you buy the May 2025 bond, you lock in 2.66% for year one, 2.69% for year two, and so on. Future changes in market rates do not affect your existing bond’s payout schedule.

Q: How do SSB returns compare to CPF interest rates?
A: The May 2025 SSB’s 10-year average of 2.78% exceeds the CPF Ordinary Account rate of 2.5% and is slightly below the Special Account’s 4.08%. However, SSBs offer full liquidity, whereas CPF funds are locked until retirement or specific conditions. After 10 years, S$100,000 in an SSB at 2.78% would grow to approximately S$131,500, compared to S$128,000 in an OA at 2.5%.
