Singapore Bond Yield Curve Explained for Investors

Singapore Bond Yield Curve Explained for Investors

The Singapore bond yield curve is a graphical representation of interest rates (yields) across different maturities for Singapore Government Securities (SGS) — from 3-month T-bills to 30-year SGS bonds. It is one of the most important macroeconomic indicators for Singapore investors, influencing everything from S-REIT valuations and mortgage rates to CPF interest rates and fixed deposit yields.

The shape and movement of the Singapore yield curve provides investors with critical information about monetary policy expectations, economic growth outlook, and the relative attractiveness of bonds versus equities and REITs.

How the Singapore Yield Curve Works

The yield curve plots yield (vertical axis) against maturity (horizontal axis) for Singapore Government Securities issued by the Monetary Authority of Singapore (MAS). Key points on the curve include: the 3-month T-bill yield, 1-year SGS, 2-year SGS, 5-year SGS, 10-year SGS, and 30-year SGS bond yields.

The MAS publishes daily benchmark SGS yields on its website. The 6-month and 1-year T-bill yields are particularly important to retail investors as they directly influence the returns on CPF funds, Singapore Savings Bonds (SSBs), and fixed deposits.

Shapes of the Yield Curve and What They Mean

  • Normal (Upward Sloping) — Long-term yields are higher than short-term yields. This reflects expectations of economic growth and rising future inflation. The most common shape, indicating healthy economic conditions.
  • Inverted (Downward Sloping) — Short-term yields exceed long-term yields. Historically a reliable recession indicator. Singapore experienced mild inversion in 2023 as the Fed’s aggressive rate hikes pushed short rates above long rates globally.
  • Flat — Short and long rates are roughly equal. Often a transition phase between normal and inverted, or inverted and normal. Signals uncertainty about the economic outlook.
  • Humped (Bell-Shaped) — Intermediate yields (e.g., 2–5 years) are highest, with shorter and longer maturities lower. Rare; indicates uncertainty about medium-term rate expectations.

How the Singapore Yield Curve Affects S-REITs

S-REITs are highly sensitive to interest rate movements, and the yield curve is the primary rate signal. When long-term yields rise: REIT valuations fall (higher discount rates compress capitalisation rates), REIT financing costs rise at debt maturity, and the relative attractiveness of REITs vs. bonds decreases for yield-seeking investors. Conversely, when long rates fall, REITs typically re-rate upward.

The 10-year SGS yield is often used as the risk-free rate benchmark in Singapore REIT valuation models. Track it at the MAS statistics portal.

Singapore T-Bills and the Short End of the Curve

The 6-month T-bill yield — determined at fortnightly auctions — became a major focus for Singapore retail investors in 2022–2023 when it peaked above 4%. This short end of the yield curve directly competes with S-REITs for investor capital. When T-bill yields are 3.5–4%+, the relative appeal of REITs yielding 5–6% narrows significantly after accounting for REIT income volatility and risk. For a practical guide, see our article on CPF vs. T-bills in Singapore.

Singapore Savings Bonds and the Yield Curve

Singapore Savings Bond (SSB) interest rates are pegged to the average 1-year to 10-year SGS yields for the preceding month. When the yield curve is steep (long rates much higher than short), SSBs are more attractive. When the curve is flat or inverted, SSBs offer less incremental return for holding to maturity. Check the current SSB rate and compare it with T-bills and fixed deposits before committing funds. More in our Singapore Savings Bonds guide.

Where can I check the Singapore bond yield curve today?
The MAS publishes daily SGS benchmark yields at eservices.mas.gov.sg. For a visual chart, the MAS also has an interactive yield curve tool. Bloomberg and Refinitiv also track Singapore yields, but the MAS portal is free and authoritative.
How does the Singapore yield curve affect fixed deposits?
Banks price fixed deposit rates relative to short-term interbank rates (SORA) and short-end SGS yields. When short-term yields are high (e.g., 3-month T-bills at 3.5%), banks must offer competitive FD rates to retain deposits. When short rates fall, FD rates typically follow within 1–2 months.
What does an inverted yield curve mean for Singapore investors?
An inverted Singapore yield curve typically signals global recession risk (since Singapore is tightly linked to global rates via MAS’s exchange rate policy). Practically, it means short-term deposits/T-bills yield more than long bonds — a good time to lock in longer-term deposits or SSBs before rates fall.
How does the yield curve affect S-REIT prices?
Rising long-term yields (steepening upward) typically pressure REIT prices as discount rates rise and bond alternatives become more attractive. Falling long-term yields support REIT re-ratings. The 10-year SGS yield is the key benchmark — watch it alongside REIT yield spreads.
Is the Singapore yield curve independent of the US Fed?
Not entirely. MAS manages Singapore’s monetary policy through the SGD exchange rate (NEER policy) rather than interest rates directly — so Singapore interest rates are partly imported from global markets. The 10-year SGS yield broadly follows the US 10-year Treasury, though with tighter spreads given Singapore’s AAA credit rating.
