Refinance Timing: Reading Rates Without Guessing
There is no perfect month to refinance, but there is a wrong way to decide: guessing where rates are headed. Singapore's floating rate loans track compounded SORA, which has traded roughly between 1.0 and 1.5 percent through 2026, so the better question is whether today's offer clears your own break even point, not a guess about tomorrow.
Money: What Your Floating Rate Is Actually Tracking
Most floating rate home loans in Singapore are priced as a spread over compounded SORA, the Singapore Overnight Rate Average that the Monetary Authority of Singapore publishes each business day based on actual interbank transactions. Three month compounded SORA has held roughly in the 1.0 to 1.5 percent range through 2026, though the exact figure moves daily and should be checked against MAS' own published data rather than an article, since this is exactly the kind of number that goes stale quickly. Read how SORA works for the mechanics behind the benchmark itself.
Money: Fixed Versus Floating When the Direction Is Unclear
A fixed rate package removes the guesswork for its fixed period, usually the first two to three years of a bank loan, and gives certainty over the exact instalment during that window, at the cost of not benefiting if the reference rate falls further. A floating package tracks compounded SORA plus a bank spread and moves with the market in both directions, which suits a borrower who can comfortably absorb a higher instalment if rates rise but wants to keep the lower cost if they do not. Neither is objectively better: the right choice depends on how much certainty is worth to a given household's budget, not on trying to out predict the market.
Timing: Why Singapore Does Not Simply Copy the US Fed
A common shortcut is to assume Singapore mortgage rates move in lockstep with United States Federal Reserve decisions, but MAS manages monetary policy through the exchange rate rather than by setting a policy interest rate the way the Fed does, so the connection to SORA runs indirectly through capital flows and money market conditions rather than a direct rate for rate mirroring. That is one more reason a headline about a foreign central bank meeting is not, on its own, a signal to refinance immediately.
MAS issues its own Monetary Policy Statement each quarter, and the language used, whether policy is described as unchanged, tightened, or eased, offers a general sense of the direction officials see for the economy, but it is not a mortgage rate forecast and should not be read as one. Treat it as background context for understanding why SORA might be drifting a certain way, not as a signal to time a refinance decision around a specific announcement date.
Timing: Waiting for the Perfect Rate Is a Cost Too
Every month spent waiting for a marginally better rate is a month spent continuing to pay the current, higher rate, so the waiting itself has a real cost that rarely gets counted. Rather than trying to time a rate cycle, which even professional forecasters get wrong regularly, compare today's actual offer against the current loan and calculate a break even period: total switching or refinancing costs divided by the monthly saving. If that period is comfortably shorter than how long the loan will be kept, the case for acting now is usually stronger than the case for waiting on a forecast. See SORA versus fixed rate for how this trade off looks once a fixed package is weighed against a floating one.
Money: What a Rate Stress Test Actually Involves
Stress testing a refinance means checking whether the new instalment would still be manageable if the floating portion of the rate rose by a meaningful margin, not just accepting today's quoted figure at face value. Since the Total Debt Servicing Ratio and Mortgage Servicing Ratio calculations that banks run already build in a buffer of this kind, a household budget that only just clears those ratios at today's rate has very little room left if rates move against it. Building a personal buffer on top of what the bank requires, rather than borrowing right up to the ratio ceiling, is the more conservative and generally safer approach regardless of which way the rate cycle eventually turns.
Safety: Ask for the Numbers, Not Just the Story
Any bank pitching a refinance, at any point in the cycle, should be able to produce the Estimated Interest Rate across the full proposed tenure, the length of any fixed period, and what reference rate and spread apply once that period ends. If a package cannot be explained in those specific terms, in writing, treat the pitch as incomplete regardless of how compelling the story around future rate moves sounds. A bank that is genuinely confident in its own package will usually put these figures in writing without hesitation or delay.
Safety: What Not to Do While You Decide
Do not lock into a long fixed rate purely out of anxiety about future increases, and do not stay on an old floating package purely out of inertia, since both are decisions made on emotion rather than arithmetic. Stress test whichever package is under consideration against a higher rate than today's, since the Total Debt Servicing Ratio rules that banks apply already assume income needs headroom above the current SORA level, and a household budget deserves the same caution. Anyone unsure whether current conditions justify moving now should check what actually happens if rates rise on their specific loan structure before deciding either way, and revisit the refinance window only once a break even number is in hand, not before.
Before signing anything, ask for the Estimated Interest Rate across the full loan tenure, not just the fixed period headline, since that single figure captures both the rate and how it is expected to behave later in one number. Also confirm that a bank must give advance notice, usually about 30 days, before a floating rate actually changes, so there is time to react rather than discover the new instalment on the day it is billed. None of this replaces reading the Letter of Offer in full, but it is a reasonable minimum before treating any single number as the whole picture.
Frequently Asked Questions
What does a floating rate home loan in Singapore actually track?
Most floating rate packages are priced as a spread over compounded SORA, the Singapore Overnight Rate Average published daily by the Monetary Authority of Singapore based on actual interbank transactions.
Where has SORA been trading in 2026?
Three month compounded SORA has held roughly between 1.0 and 1.5 percent through 2026, though the exact figure moves daily and should be checked against MAS' own published data rather than an older article.
Is it better to wait for a lower rate before refinancing?
Not necessarily. Waiting has its own cost, since the current rate keeps being paid while waiting, so comparing today's actual offer against a break even period is usually more useful than trying to predict where rates go next.
Getting the Timing Right
Timing a refinance well means running your own break even numbers against today's actual offer, not guessing at where rates go next.
