Interest Rate Derivatives Singapore: How Borrowers and Investors Hedge Against Rising or Falling SORA

Interest rate derivatives — including interest rate swaps, forward rate agreements and SORA futures — are contracts used to manage exposure to interest rate movements, letting banks, corporates, REITs and bond investors hedge or speculate on rate changes without altering their underlying loans or bonds.

Key Takeaways

• Interest rate derivatives let borrowers and investors manage the risk of interest rates moving against them, without having to refinance or restructure the underlying loan or bond itself.
• Singapore’s shift from SOR to SORA, completed in 2024, made SORA-based interest rate swaps and SGX SORA futures the primary tools for managing SGD interest rate risk.
• S-REITs and corporates with floating-rate, SORA-linked borrowings commonly use interest rate swaps to convert variable interest payments into fixed, more predictable ones.
• Most interest rate derivatives trade over-the-counter (OTC) between banks and institutions, though SGX SORA futures provide an exchange-traded, centrally cleared alternative.
• Retail access to interest rate derivatives in Singapore is very limited; most individuals experience their effects indirectly through loan pricing and REIT financing costs.

What Is Interest Rate Derivatives Singapore?

An interest rate derivative is a financial contract whose value depends on the level of interest rates, used primarily to manage the risk that rates will move in an unfavourable direction. The most common form is the interest rate swap (IRS), where two parties exchange interest payment streams — typically one paying a fixed rate and the other paying a floating rate tied to a benchmark like SORA — on the same notional amount, without exchanging the underlying principal itself.

Other common interest rate derivatives include forward rate agreements (FRAs), which lock in a future interest rate for a short period, swaptions (options on interest rate swaps), and exchange-traded interest rate futures, which let market participants hedge or speculate on rate movements through a standardised, exchange-cleared product.

How Does Interest Rate Derivatives Singapore Work in Singapore?

Singapore completed its transition away from the Swap Offer Rate (SOR) to the Singapore Overnight Rate Average (SORA) as the primary SGD interest rate benchmark by 2024. This shift made SORA-based interest rate swaps the standard tool for hedging SGD interest rate exposure, replacing the SOR-based swaps that were widely used before.

In practice, S-REITs and corporates with floating-rate, SORA-linked loans frequently enter into interest rate swaps to convert their variable interest payments into fixed ones, locking in predictable borrowing costs and reducing the risk that rising SORA pushes up their financing expenses. SGX has also launched SORA futures, giving institutions an exchange-traded, centrally cleared way to hedge or take a view on SGD interest rate direction, complementing the OTC swap market that remains the dominant venue for larger, customised hedges.

Interest Rate Derivatives Singapore Example

An S-REIT has S$200 million of SORA-linked floating-rate debt and is concerned that rising rates will increase its interest expense and squeeze distributable income. It enters into an interest rate swap with a bank, agreeing to pay a fixed rate of 3.2% per annum on the S$200 million notional, while receiving SORA-linked floating payments from the bank in return. If SORA rises above 3.2%, the swap effectively offsets the REIT’s higher floating-rate interest cost on its actual loan, keeping its net financing cost close to the fixed 3.2% it locked in.

Advantages of Interest Rate Derivatives Singapore

• Hedges against rate volatility — borrowers can protect their financing costs from unexpected increases in SORA or other benchmark rates.
• Predictable cash flows — converting floating payments to fixed through a swap makes budgeting and distribution planning more reliable, especially for REITs.
• Available in flexible tenors — swaps and FRAs can be structured to match a specific loan’s remaining maturity or a particular hedging horizon.
• Can be unwound or adjusted — sophisticated users can restructure their hedge positions as circumstances change, rather than being locked into one fixed-rate loan structure.

Risks and Limitations

• Counterparty risk on OTC swaps — if the swap counterparty (often a bank) defaults, the hedge may not perform as intended.
• Cost if rates move the other way — locking in a fixed rate through a swap means missing out if floating rates subsequently fall below the fixed rate agreed.
• Complexity — pricing, mark-to-market valuation and accounting treatment of interest rate derivatives require specialised expertise.
• Very limited retail access — individual Singapore investors cannot practically use these instruments to hedge their own personal mortgage or loan exposure.

Interest Rate Derivatives vs Fixed-Rate Bonds

The Bottom Line

For Singapore investors, interest rate derivatives matter mainly because S-REITs and corporates they invest in use them to manage financing costs in a SORA-driven rate environment, directly affecting distributable income and dividend stability. Checking how much of a REIT’s debt is hedged with interest rate swaps is a useful, often-overlooked step before assessing its interest rate risk.
