Key Takeaways
- A cross currency swap exchanges both principal and periodic interest payments in two different currencies, unlike an interest rate swap, which stays within a single currency.
- Singapore banks including DBS, OCBC and UOB offer cross currency swaps to corporate treasury clients, mainly to hedge SGD/USD exposure on cross-border loans and bonds.
- Tenors typically run from 1 to 10 years, and the swap is usually documented under a standard ISDA Master Agreement between the two counterparties.
- Unlike a forward contract, which settles on a single future date, a cross currency swap involves periodic interest exchanges throughout the life of the trade.
- Retail investors rarely trade cross currency swaps directly, but the swap market indirectly influences SGD bond pricing and bank funding costs that feed through to deposit and loan rates.
What Is a Cross Currency Swap?
A cross currency swap (CCS) is an over-the-counter (OTC) derivative in which two counterparties agree to exchange principal amounts in two different currencies at the start of the contract, make periodic interest payments to each other in their respective currencies over the life of the trade, and then re-exchange the original principal amounts at maturity, usually at the same exchange rate used at inception. This structure means a CCS combines elements of a foreign exchange transaction with an interest rate swap, which is why it is sometimes described as a “currency and interest rate swap”.
Singapore’s position as a regional financial and treasury hub makes cross currency swaps an important tool. Many multinational companies headquartered or with regional treasury centres in Singapore raise debt in US dollars or euros because of deeper capital markets and lower absolute coupon rates, but generate revenue predominantly in Singapore dollars. A cross currency swap lets them convert that USD or EUR liability into an effective SGD liability, removing the currency mismatch between their borrowing and their cash flows.
How Does a Cross Currency Swap Work in Singapore?
In Singapore, cross currency swaps are arranged bilaterally between banks and corporate or institutional clients, and between banks themselves in the interbank market. The Monetary Authority of Singapore (MAS) requires licensed banks to report OTC derivative transactions, including cross currency swaps, to a trade repository under its OTC derivatives reporting regime, which took full effect for all five asset classes (interest rate, FX, credit, equity and commodity derivatives) by the mid-2020s. This gives MAS visibility into systemic risk building up in the derivatives market without directly restricting access for corporate hedgers.
Pricing for an SGD/USD cross currency swap reflects the “cross currency basis” — the premium or discount that reflects relative demand for USD versus SGD funding. When USD funding is in high demand (common during periods of US dollar strength or global risk aversion), the basis can turn negative for SGD-based borrowers, making it more expensive to swap USD debt into SGD. Singapore corporate treasurers and REIT managers who hold foreign-currency borrowings — for example, overseas property or data centre assets financed partly in USD — monitor this basis closely when timing a swap.
Cross Currency Swap Example
Suppose a Singapore-listed company issues a 5-year USD 50 million bond at a fixed coupon of 5.2% per annum, because USD institutional investors offer a lower rate than the SGD market would for the same credit. The company’s revenues, however, are almost entirely in SGD. To remove this currency mismatch, it enters a 5-year cross currency swap with its bank: at inception, it receives USD 50 million (which it uses to settle the bond proceeds swap) and pays out the SGD equivalent, say SGD 67.5 million at the prevailing exchange rate of 1.35.
Over the next 5 years, the company pays SGD interest to the bank (based on a fixed or SORA-linked floating SGD rate, say 3.6% per annum) and receives USD interest from the bank (5.2% per annum), which it then uses to pay its USD bondholders. At maturity, the principal amounts are re-exchanged at the original 1.35 rate, insulating the company from exchange rate movements over the 5 years. In effect, the company has converted a USD-denominated, 5.2% bond into a synthetic SGD-denominated, 3.6% liability.
Advantages of a Cross Currency Swap
- Hedges both FX and interest rate risk in one trade. A single cross currency swap removes currency mismatch and can simultaneously convert fixed-rate exposure into floating, or vice versa.
- Access to cheaper offshore capital. It lets Singapore borrowers tap deeper USD or EUR bond markets for lower all-in funding costs, then swap the proceeds back to SGD.
- Customisable tenor and structure. Unlike exchange-traded futures, a CCS can be tailored to match the exact maturity, notional and payment schedule of the underlying loan or bond.
- Reduces earnings volatility. By locking in the SGD-equivalent interest cost upfront, companies avoid currency-driven swings in their reported interest expense.
Risks and Limitations
- Counterparty credit risk. If the bank on the other side of the swap defaults, the company may be left without the hedge it was relying on, though central clearing and collateral posting mitigate this for larger trades.
- Mark-to-market volatility. Even though the swap hedges the underlying exposure, its fair value can swing significantly with interest rate and currency moves, creating accounting volatility under SFRS(I) 9 if hedge accounting is not properly applied.
- Documentation complexity. Entering a CCS requires an ISDA Master Agreement, credit support annex and internal treasury policy approval — a meaningful hurdle for smaller SMEs.
- Exit illiquidity. Unwinding a cross currency swap before maturity often carries a breakage cost, which can be substantial if rates or the currency basis have moved against the position.
Common Mistakes Singapore Investors Make
The most frequent mistake is assuming a cross currency swap is a retail-accessible product simply because it appears in a REIT’s or company’s annual report. In practice, these are corporate treasury instruments requiring ISDA documentation, credit lines and minimum notional sizes far beyond what individual investors could access directly. The more useful exercise for a Singapore investor is reading how much of a REIT’s foreign-currency debt is swapped back to SGD in its quarterly disclosures, since an unhedged currency mismatch on overseas assets can create distribution volatility that has nothing to do with the quality of the underlying property.
A second mistake is conflating the cross currency basis with simple interest rate differentials. The basis can move independently of underlying rates due to supply and demand for each currency’s funding, which is why the cost of swapping USD debt into SGD can rise even when neither SORA nor US rates have changed materially — it is a distinct risk factor worth understanding rather than lumping into general interest rate risk.
Cross Currency Swap vs Interest Rate Swap
The two are often confused because both exchange interest payments, but they differ in a crucial way — whether currencies and principal are exchanged.
| Feature | Cross Currency Swap | Interest Rate Swap |
|---|---|---|
| Currencies involved | Two different currencies | Single currency |
| Principal exchanged | Yes, at start and maturity | No, notional is used only for calculation |
| Primary use in Singapore | Hedge USD/EUR debt into SGD or vice versa | Convert SORA floating-rate debt into fixed, or vice versa |
| Typical users | MNCs, REITs with overseas assets, SG issuers of foreign-currency bonds | Corporates and REITs with SGD floating-rate loans |
| Complexity | Higher — combines FX and rate risk | Lower — rate risk only |

The Bottom Line
For Singapore-based multinationals, REITs with overseas exposure and large SGX-listed borrowers, a cross currency swap is the standard tool for converting foreign-currency debt into an effective SGD liability without refinancing the underlying bond or loan. It is a corporate treasury instrument rather than a retail one, but its pricing — the SGD/USD cross currency basis — ripples through to the cost of capital that ultimately shapes dividend policy and bond yields that Singapore investors do see.
Frequently Asked Questions
What is a cross currency swap in simple terms?
A cross currency swap is an agreement between two parties to exchange loan principal and interest payments in two different currencies, allowing a borrower to effectively convert debt from one currency into another without refinancing.
Who uses cross currency swaps in Singapore?
Mainly banks, multinational corporations, and S-REITs or companies with overseas assets or foreign-currency bonds, who use the swap to hedge currency mismatches between their borrowings and their SGD revenues.
What is the difference between a cross currency swap and a forward contract?
A forward contract settles on a single future date, while a cross currency swap involves an exchange of principal at the start, ongoing periodic interest payments over the life of the trade, and a re-exchange of principal at maturity.
Can retail investors in Singapore trade cross currency swaps?
Not directly through a typical retail brokerage — cross currency swaps are OTC instruments arranged between banks and corporate or institutional clients, usually requiring ISDA documentation and credit lines that retail investors do not have.
Why does the cross currency basis matter for Singapore borrowers?
The cross currency basis reflects the relative cost of swapping SGD into USD or vice versa; when it moves against a borrower, hedging foreign-currency debt into SGD becomes more expensive, which can affect a company’s reported interest costs and, ultimately, shareholder returns.
Does a cross currency swap show up in a REIT's financial statements?
Yes, REITs with foreign-currency borrowings typically disclose the extent of their currency hedging, including cross currency swaps, in their quarterly and annual reports under financial risk management notes.
