Singapore Yield Curve: What SGS Bond Rates Across Maturities Tell Investors
Reading the shape of the SGS yield curve to gauge growth expectations and REIT borrowing costs
The Singapore yield curve is a graph plotting the yields of Singapore Government Securities (SGS) across different maturities, from short-dated T-bills to long-dated 30-year bonds, at a single point in time — its shape (normal, flat, or inverted) reflects the market’s collective expectations for future interest rates, inflation, and economic growth.

- The Singapore yield curve plots SGS yields across maturities from 3-month T-bills out to 30-year bonds, published daily by the Monetary Authority of Singapore (MAS).
- A ‘normal’ upward-sloping curve, where longer-dated bonds yield more than shorter-dated ones, typically signals expectations of steady growth and gradually rising rates over time.
- An ‘inverted’ curve, where short-term yields exceed long-term yields, has historically been watched as a signal of slowing growth or recession risk, though Singapore’s curve shape is also heavily influenced by US Treasury yields and MAS’s exchange-rate-centred monetary policy.
- S-REITs and other interest-rate-sensitive sectors are closely tied to the yield curve, since REIT borrowing costs and the yield spread investors demand over ‘risk-free’ SGS bonds both move with the curve.
- Because Singapore uses an exchange-rate-based monetary policy rather than directly setting a policy interest rate, the SGS yield curve tends to track global (especially US) rate expectations closely, rather than being driven primarily by a domestic policy rate decision.

What Is SG Yield Curve?
Unlike a single interest rate, the yield curve captures the entire relationship between a bond’s time to maturity and its yield, for bonds of the same credit quality — in Singapore’s case, SGS bonds issued and guaranteed by the Singapore government, considered effectively risk-free in domestic currency terms. Plotting the yield of the 3-month T-bill, 1-year, 2-year, 5-year, 10-year, 20-year and 30-year SGS bonds on a single chart produces the yield curve, and its shape at any given time is one of the most closely watched signals in fixed income markets globally, including by Singapore REIT and bond investors.
A normal, upward-sloping curve is the most common shape historically, reflecting the basic principle that investors generally demand higher compensation for locking up money for longer, given the greater uncertainty over inflation and rates over a longer horizon. When the curve flattens or inverts — short rates rising above or converging with long rates — it often reflects market expectations that growth or inflation will slow enough that the central bank (in Singapore’s case, by extension through MAS’s monetary policy stance and its link to US Federal Reserve rate expectations) will eventually need to cut rates.
Singapore’s monetary policy framework is distinctive: instead of directly targeting a short-term interest rate like most central banks, MAS manages the exchange rate of the Singapore dollar against a basket of currencies (the S$NEER). This means SGS yields, especially at the short end, are influenced heavily by global rate expectations — particularly US Treasury yields — transmitted through currency and capital flow channels, rather than a direct domestic policy rate decision.
How It Works in Singapore
MAS publishes the SGS yield curve daily, and investors commonly reference specific maturity points — the 2-year, 10-year, and 30-year SGS yields — as shorthand for different parts of the curve. The 2-year yield is more sensitive to near-term rate expectations, while the 10-year and 30-year yields reflect longer-run growth, inflation, and term-premium expectations.
| Curve Shape | What It Typically Signals |
|---|---|
| Normal (upward-sloping) | Steady growth expectations, gradually rising rates over time |
| Flat | Uncertainty or a transition point in the rate cycle |
| Inverted (downward-sloping) | Market pricing in future rate cuts, often associated with slower growth or recession risk |

For S-REIT investors specifically, the 10-year SGS yield is a particularly important reference point, since it is commonly used as the “risk-free rate” baseline against which a REIT’s distribution yield is compared — the difference between a REIT’s yield and the 10-year SGS yield is often called the yield spread, and a widening spread can reflect either rising REIT-specific risk or a general repricing of risk appetite across the market, independent of the REIT’s own operating performance.
Worked Example
Suppose the 2-year SGS yield is 2.8% and the 10-year SGS yield is 3.2% in a given month — a normal, modestly upward-sloping curve, consistent with steady but unspectacular growth expectations. An S-REIT with a distribution yield of 5.8% in that environment would be trading at a yield spread of roughly 2.6 percentage points (5.8% minus 3.2%) over the 10-year SGS benchmark, a spread investors would compare against the REIT’s own historical average spread and against peer REITs to judge whether it looks cheap, fairly valued, or expensive relative to the risk-free rate.
If the curve were instead to invert — say the 2-year yield rises to 3.5% while the 10-year stays at 3.2% — it would suggest the market expects rates to be cut over the coming years, often because growth is expected to slow. In that scenario, REIT investors would typically watch closely for signs of weakening tenant demand or rental reversions turning negative, since an inverted curve has historically preceded periods of economic softness, even though Singapore’s small, open economy and REIT sector can diverge from this pattern depending on sector-specific dynamics.
Advantages
- A single, transparent signal of market rate expectations. The yield curve distills enormous amounts of information about growth, inflation and policy expectations into one easily interpretable shape.
- Directly useful for REIT and bond valuation. The curve provides the risk-free benchmark rates used to calculate yield spreads for REITs, corporate bonds, and other fixed income instruments.
- Published daily and freely available. MAS publishes SGS yield curve data openly, giving retail investors the same reference data used by institutional fixed income desks.
- Helps with bond laddering and duration decisions. Investors building an SGS or T-bill ladder can use the curve to decide how much extra yield is available for extending maturity, informing whether locking in longer-dated bonds is worthwhile.
Risks and Limitations
- Curve shape is not a perfect recession predictor. While an inverted curve has preceded past recessions in major economies, the lead time and reliability of the signal vary, and Singapore’s curve is additionally influenced by its unique exchange-rate-based monetary framework.
- Heavily influenced by external factors. Because Singapore’s monetary policy operates through the exchange rate rather than a domestic policy rate, SGS yields — and therefore the curve’s shape — are strongly affected by US Treasury yields and global capital flows, sometimes diverging from purely domestic economic conditions.
- Can mislead if read in isolation. A flattening or inverting curve driven by a temporary technical factor (such as heavy foreign demand for long-dated SGS bonds) may not carry the same economic signal as one driven by genuine growth concerns.
- Yield spread compression risk for REITs. A sharp, sustained rise in SGS yields across the curve compresses the yield spread REITs offer over the risk-free rate, which can pressure REIT unit prices even if the REIT’s own operating fundamentals are unchanged.
Normal Yield Curve vs Inverted Yield Curve
| Feature | Normal Yield Curve | Inverted Yield Curve |
|---|---|---|
| Shape | Upward-sloping — long yields higher than short yields | Downward-sloping — short yields higher than long yields |
| Typical signal | Steady growth, gradually rising rates expected | Market pricing in future rate cuts, slower growth expected |
| Historical frequency | The more common, ‘default’ shape over most of economic history | Relatively rare, often associated with pre-recessionary periods |
| Impact on REIT yield spreads | Spreads tend to be more stable | Spreads can compress or widen sharply depending on which part of the curve REITs are priced against |
| Relevance to T-bill investors | Rolling over short T-bills may yield less than locking in longer SGS bonds | Short T-bills can temporarily offer higher yields than longer bonds |
The Bottom Line
The Singapore yield curve is a free, daily-updated map of how the market prices risk-free money across time, and its shape carries real information for REIT investors, bond investors, and anyone deciding how far out on the maturity spectrum to lend their money. While not an infallible economic forecasting tool, tracking the curve alongside REIT yield spreads gives Singapore investors a more grounded basis for judging whether current valuations reflect genuine risk, or simply the broader direction of global interest rates.

Frequently Asked Questions
Where can I check the current Singapore yield curve?
The Monetary Authority of Singapore publishes daily SGS yield curve data on its official website, covering maturities from short-dated T-bills through to 30-year SGS bonds.
What does an inverted yield curve mean for Singapore investors?
An inverted curve, where short-term yields exceed long-term yields, has historically signalled market expectations of slower growth or future rate cuts, though Singapore’s curve is also shaped by global rate trends given its exchange-rate-based monetary policy.
Why do REIT investors care about the yield curve?
The 10-year SGS yield is commonly used as the risk-free benchmark against which a REIT’s distribution yield is compared; changes in the curve directly affect the ‘yield spread’ that REIT investors demand, which can move REIT unit prices.
Is Singapore's yield curve set by MAS the same way a central bank sets interest rates elsewhere?
Not directly. MAS manages monetary policy primarily through the exchange rate of the Singapore dollar rather than a domestic policy interest rate, so SGS yields are influenced heavily by global rate expectations, especially from the US, transmitted through currency and capital flow channels.
How often does the shape of the yield curve change?
The curve can shift daily in response to new economic data, central bank commentary, and global bond market moves, though major shape changes (such as a shift from normal to inverted) typically develop over weeks to months rather than a single trading day.
