Most borrowers frame the mortgage decision as a binary choice, fixed or floating, and pick one. Fewer realise that several banks in Singapore will let you split a single loan across both structures at once. It is not a product most people ask about by name, but it solves a real problem for a specific kind of borrower: someone who does not want to bet the entire loan on being right about where rates are headed.
What a combination loan actually is
A combination, or combo, loan divides your total loan quantum into two or more tranches within a single mortgage. One portion is placed on a fixed rate package, giving you a locked, predictable monthly payment on that slice for the fixed period. The remaining portion sits on a floating rate package, typically pegged to SORA, the Singapore Overnight Rate Average, which moves with the market. Both tranches are usually disbursed and serviced together as one loan against the same property, but each tranche follows its own rate mechanics from that point on.
The effect is a blended monthly payment that moves partially with the market rather than fully in either direction. If rates rise, only your floating tranche's payment increases, cushioning the impact compared to a fully floating loan. If rates fall, only your floating tranche benefits, so you capture some of the upside you would have missed with a fully fixed loan.
Why banks offer this structure
Banks offer combination loans because a meaningful segment of borrowers, particularly those with larger loan quantums where rate movements translate into larger dollar swings, want a middle path rather than a full commitment either way. It also lets banks retain borrowers who might otherwise split their preference between two different loan products entirely, or hesitate to commit at all. For the borrower, it is a genuine risk management tool rather than a marketing gimmick, provided you understand what you are actually buying: a hedge, not a way to beat the market on both sides simultaneously.
The trade off versus a single package
| Structure | What you get | What you give up |
|---|---|---|
| Fully fixed | Complete payment predictability for the fixed period | No benefit if rates fall during that period |
| Fully floating | Full benefit if rates fall, generally more flexible to refinance | Full exposure if rates rise |
| Combination Middle path | Partial protection against rises, partial benefit from falls | Neither full certainty nor full upside, plus more complex terms |
Directional comparison only. Actual rates, split ratios and terms vary by bank; confirm current packages before deciding.
The trade off is straightforward once you see it laid out: a combination loan does not give you the best of both worlds, it gives you a smoothed version of both worlds. That is precisely the point for a borrower who values not having their full monthly payment swing with the market, but who also does not want to give up all upside by locking in completely.
When a combination loan makes sense
This structure tends to suit a few specific situations. A larger loan quantum, where even a modest rate move translates into a meaningful dollar difference in monthly payments, is the most common case, since the hedging value scales with loan size. A borrower who is genuinely uncertain about the rate direction over their holding horizon, rather than having a strong conviction either way, is also a natural fit, since the combo loan avoids betting the whole loan on a view you are not confident in. It can also suit someone whose risk tolerance sits between the two extremes: uncomfortable with full floating exposure, but also unwilling to pay away all upside for full fixed certainty.
Conversely, if you have a strong view that rates are heading in a particular direction over your holding period, or if you strongly prioritise simplicity over optimisation, a single package loan is usually the more straightforward choice. For the underlying comparison this builds on, my fixed versus floating mortgage guide covers the two pure options in depth.
How the split is typically structured
Most banks offering combination loans let the borrower choose the ratio between the two tranches, commonly around an even split, though other ratios are often available, sometimes subject to a minimum tranche size on the smaller portion. The exact flexibility, minimum quantum per tranche, and which packages can be combined varies by bank and by the specific product, so this is very much a case by case conversation with your mortgage banker or broker rather than a standardised feature across the market.
Refinancing and repricing considerations
Before committing to a combination loan, ask specifically how each tranche's lock in period is structured, what the penalty looks like if you need to exit either tranche early, and whether the bank allows repricing or refinancing one tranche independently of the other. This detail matters far more with a combo loan than with a single package, precisely because you are managing two sets of terms instead of one. My mortgage lock in period guide and refinancing guide both cover the mechanics that apply to each tranche individually.
How to decide if it fits your situation
- Size the hedge to your loan quantum. The larger your loan, the more a partial hedge against rate swings is likely to matter in absolute dollar terms.
- Be honest about your conviction on rates. If you genuinely have no strong view on rate direction over your holding period, a combo loan matches that uncertainty better than committing fully either way.
- Map out both tranches' lock in periods before signing. Make sure you understand exactly when each portion becomes free to refinance or reprice.
- Compare the blended cost against your alternatives. Ask your banker to show you the combo loan's blended rate against a fully fixed and a fully floating package at the same point in time, so you are choosing with full information rather than assuming the split is automatically the safer option.
Frequently asked questions
What is a combination home loan in Singapore?
A combination loan splits a single mortgage into two or more tranches, with part of the loan quantum on a fixed rate package and the remainder on a floating, typically SORA pegged, rate package. Both tranches sit within the same overall loan but each follows its own rate structure and, in some cases, its own lock in period.
Can I choose the ratio between fixed and floating in a combo loan?
Generally yes, within limits set by the bank. Common splits are around half fixed and half floating, though some banks allow other ratios, sometimes subject to a minimum tranche size for each portion. Confirm the available split ratios directly with the bank you are considering.
Is a combination loan more expensive than a single package?
Not inherently. A combination loan's blended cost sits between what a fully fixed and a fully floating package would cost, since it is a mix of the two. It is a different risk profile rather than automatically cheaper or more expensive: you give up some certainty of a fully fixed loan and some upside of a fully floating one, in exchange for a middle ground on both.
Can I refinance a combination loan?
Yes, but the mechanics are more involved than refinancing a single package loan, because each tranche may carry its own lock in period and penalty structure. If your tranches have different lock in expiry dates, you may need to time a refinance around whichever tranche is unlocked first, or accept a penalty on the tranche still within its lock in.
