Is a 1.40% Fixed Worth It Over a 1.27% Float?

For most of the last rate cycle, choosing fixed over floating cost real money — a fixed rate sat well above the floating one, and you paid a visible premium for the certainty. In mid-2026 that premium has nearly vanished. The cheapest two-year fixed rate on the board is about 1.40%. The cheapest floating rate is 1.27% — three-month SORA at roughly 1.07% plus a 0.20% margin (PropertyNet.SG). The entire decision now hinges on a 0.13% gap. The interesting question isn't which rate is lower today — float obviously is — but whether that thin gap is a smart price to pay for two years of not having to think about SORA.

What the spread actually costs

Take a $1,000,000 loan over 25 years — a typical upgrader's mortgage. At 1.40% fixed, the monthly repayment is $3,953. At 1.27% floating, it's $3,892. The difference is $60 a month. Hold both rates flat across a two-year lock-in and the fixed borrower pays about $27,095 in interest against the floating borrower's $24,566 — a certainty premium of roughly $2,500 over two years, or about $1,300 in the first year.

That is genuinely small. In a 3% environment, a comparable fixed-over-float spread could run several hundred dollars a month. At today's pricing you're paying about the cost of one nice dinner a month to lock your rate. The fixed package isn't expensive in absolute terms — it's cheap insurance. The only question is whether you need the insurance at all.

The catch: float only has to rise 13 basis points

Here's what makes this decision genuinely close rather than an obvious "take the float." The floating rate is cheaper only while SORA stays put. Work out the breakeven: for the floating loan to cost the same as the 1.40% fixed over the two-year lock-in, the floating rate would need to average 1.40% across those 24 months. Since the margin is fixed at 0.20%, that means three-month SORA would need to average just 1.20% — only 13 basis points above where it sits today (~1.07%).

Thirteen basis points is nothing. It's a rounding error in rate terms. And the forward curve already points that way: consensus has SORA drifting up toward 1.39% by year-end as the cyclical low passes (PropertyGuru). If that plays out, the floating rate spends the back half of the lock-in above 1.40%, not below it.

To put numbers on it: suppose the float holds at 1.27% for the first year, then rises so it sits at 1.59% (SORA ~1.39% + 0.20%) for the second year. Over the two years the floating borrower now pays about $27,628 in interest — $533 more than the fixed borrower. The certainty premium has flipped into a small saving. That's not a dramatic reversal, but it shows how finely balanced this is: a modest, widely-forecast SORA move is enough to make the "more expensive" fixed rate the cheaper one in hindsight.

So is SORA going up or down?

Nobody knows, and anyone who tells you they do is selling something. What can be said is narrower. SORA is near a multi-year floor; most forecasts put it in a 0.7%–1.5% band for the rest of 2026, with a modest upward drift more likely than a further fall (MAS). A useful reminder on the policy side: MAS doesn't set interest rates directly the way the US Federal Reserve does — it manages the Singapore dollar against a trade-weighted basket, and domestic rates like SORA largely follow global rates and the currency stance. So the risk isn't a MAS "rate hike"; it's that global rates firm up or the local cyclical low simply passes, nudging SORA off the floor.

The asymmetry matters. From near a floor, the room to fall is small and the room to rise is larger. That doesn't guarantee float will rise — but it means the 0.13% you'd pay to fix is buying protection against the more likely direction of surprise, not the less likely one.

Who should pay the premium

This is where the thin spread actually simplifies the decision, because the cost of being wrong is so low either way.

Fix if certainty has real value to you. If your budget is tight, if this is your first mortgage and a payment shock would genuinely hurt, or if you simply don't want to monitor SORA and reprice in two years, paying $60 a month to lock 1.40% is cheap peace of mind. You give up a near-certain ~$2,500 of savings only if SORA stays flat or falls — and in exchange you're fully protected if it climbs. At this spread, that's a reasonable trade for most households who value a predictable bill.

Float if you're rate-aware and flexible. If you have a comfortable buffer, you watch rates anyway, and you're prepared to reprice or refinance the moment the cycle turns, the floating rate is genuinely cheaper today and you keep the optionality. Crucially, most floating packages have no lock-in or a short one — so if SORA rises you can move to a fixed rate then, rather than pre-paying for protection you may not need. The floater's edge isn't the 0.13%; it's the freedom to react.

The one combination to avoid is floating because it's cheaper while having neither the buffer to absorb a rise nor the discipline to act when one comes. That's taking the rate risk without the tools to manage it — the worst of both packages.

The bottom line

When the fixed-float spread was wide, the choice was about how much certainty was worth. At 0.13%, it isn't really about cost anymore — both rates are cheap and within ~$60 a month of each other. It's about temperament. Float saves a little if rates sit still; fixed protects you completely if they don't, for the price of a monthly dinner. With SORA near its floor and the consensus pointing gently upward, paying that small premium to fix is the more defensible default for anyone who'd lose sleep over the alternative — and an easy pass for anyone who wouldn't.

General information only, not financial advice. Indicative rates as at June 2026: cheapest two-year fixed ~1.40%; cheapest floating ~1.27% (three-month SORA ~1.07% + 0.20% margin); rates change without notice and vary by loan size and property type (PropertyNet.SG, MAS SORA). Monthly repayments, two-year interest totals and the breakeven SORA level were computed for the stated assumptions ($1,000,000 loan, 25-year tenure). SORA's future path is uncertain; the forecasts cited are third-party estimates, not guarantees.
