Obsessed about optimising interest costs vs savings for all types of mortgages in Singapore.

Youāve found the flat, agreed on the price, and put down the option fee. Then the banker calls back. The loan they can approve comes in lower than the number you need, and the place youād already pictured yourself living in starts to feel out of reach.
Itās a common spot to be in, and itās usually fixable. The loan falls short for one reason. Your Total Debt Servicing Ratio, or TDSR, is the rule that caps your total monthly debt at 55% of your gross income, so if your recognised income isnāt high enough, the loan gets capped with it. Thatās a common spot for anyone borrowing on one income, including someone taking out a fresh loan for a HDB flat after a divorce, where the householdās borrowing power has changed.
There is one, and itās fully sanctioned by the Monetary Authority of Singapore (MAS). You can convert eligible financial assets into recognised income two ways: by pledging or by showing. By the end of this piece youāll know how each works, what each costs you in locked-up cash, and how to combine them to close the gap on your home loan in Singapore.
Pledging means formally committing eligible financial assets to the bank and locking them for a fixed period, currently a minimum of four years, or 48 months, under the MAS framework. In return, the bank treats those assets as extra income.
The mechanic is simple. The bank takes the pledged amount, divides it by 48, and adds the result to your gross monthly income for the TDSR calculation.
Say you pledge $200,000 in cash. Divided by 48, that adds $4,167 to your recognised monthly income. At the 55% TDSR limit, on a 30-year loan assessed at the 4% medium-term rate banks use to stress-test affordability, that extra income unlocks roughly $480,000 more in borrowing.
What counts as eligible? Cash and fixed deposits, Singapore Government Securities and Singapore Savings Bonds, listed shares, unit trusts, gold and similar assets. One thing to watch: pledged cash and fixed deposits are usually recognised in full, but other asset classes are often haircut first, meaning only part of their value counts, and the exact treatment varies from bank to bank.
Pledging works for loans governed by TDSR, which covers bank loans generally and, most commonly, buying private property in Singapore. Itās worth flagging that a HDB flat or an Executive Condominium (EC) bought from a developer also has to clear the Mortgage Servicing Ratio (MSR), a separate rule that caps your mortgage repayment at 30% of gross income. Pledging lifts your recognised income, but MSR is the tighter constraint on those purchases, so it doesnāt free up borrowing the same way. Confirm the current treatment with the bank rather than assuming it.
Now the honest part. The money is genuinely locked. For the full pledge period, you canāt touch it, spend it, or invest it elsewhere. Thatās the real cost, and itās the thing to weigh before you sign.
Hereās the practical sequence:
Youāll need statements evidencing the assets, and the pledge stays tied to that one loan with that one bank. A fair question is what happens if you sell the property or refinance before the term ends. In practice, the pledge is usually released when the loan is redeemed, but the conditions differ by bank, so check them before you commit rather than after.
Showing funds, sometimes called using unpledged funds, means proving you hold eligible assets without locking them away. You show the bank the balances, they count a portion towards your income, and the money stays yours to use.
The trade-off sits in that word āportionā. When you show funds for a bank loan, only 30% of the eligible asset value is recognised, and that reduced figure is then divided by 48 and added to your monthly income. So the same dollar does far less work shown than pledged, but it stays completely liquid.
This suits a different buyer. If you only need a modest top-up, or you canāt afford to lock funds away because you need them for the down payment, stamp duty or a cash buffer, showing nudges your recognised income up while keeping your options open.
Take the same $200,000 from the pledging example. Shown rather than pledged, only 30% counts, so $60,000 is recognised. Divided by 48, that adds $1,250 to your monthly income, which unlocks roughly $144,000 more in borrowing on the same 30-year, 4% basis.
Line the two up and the gap is stark. The same $200,000 pledged unlocked around $480,000. Shown, it unlocks about $144,000. Same money, roughly a third of the borrowing power, in exchange for keeping it liquid.
The bank will want evidence of the balances, and it usually expects the funds to stay in place rather than be spent the moment the loan clears. So showing isnāt quite free of strings, but itās a long way from locking the money down for four years.

The clearest way to see it is side by side.
| Factor | Pledging | Showing |
| Recognition rate | Full eligible value | 30% of value |
| Locked up? | Yes, min. 4 years | No |
| Division by 48 | Yes | Yes |
| Loan unlocked per dollar | Higher | Lower |
| Liquidity | None during the term | Full |
| Risk | Cash inaccessible if needed | Minimal |
The read-out is straightforward. Pledging buys you far more borrowing power per dollar, but it costs you access to your cash. Showing preserves your access, but it does much less lifting. Thereās no single show funds calculator that fits every bank, because each one haircuts assets differently, so treat any figure you generate as a starting estimate, not a promise.
As a rule of thumb: pledge when you need maximum uplift and can spare the cash, and show when you need a modest top-up and want to stay liquid.
Most people treat this as either/or, but you donāt have to choose. You can pledge a portion and show the rest, tuning the split to how much cash you can afford to lock away.
Take Wei. Heās about $200,000 short on the loan he needs. Closing that gap takes roughly $1,700 in extra recognised monthly income, on a 30-year loan stressed at 4% under the 55% TDSR limit. He has $200,000 in eligible assets, but he wants to keep a good chunk liquid for the cash part of his downpayment, his Buyerās Stamp Duty and a renovation buffer. This is a common squeeze for anyone upgrading from a HDB flat to a condo and buying before they sell, where the money is tied up in the current home until itās sold.
So he splits it. He pledges $80,000, which adds $1,667 a month. Then he shows $40,000, which adds another $250. Together thatās $1,917 in recognised income, comfortably clearing his gap and unlocking around $220,000 more in borrowing. Only $80,000 is actually locked. The rest stays within reach.
Notice how little the shown portion adds, $250 against the pledgeās $1,667. Thatās the 30% haircut at work, and itās why showing is a top-up rather than the workhorse. The levers to weigh are how much cash you genuinely need free, set against the loan each dollar buys you pledged versus shown.
Where it gets fiddly is that banks differ on which assets they accept and how heavily they haircut them, so the best split for you can change from one lender to the next. Modelling that across banks is the kind of thing we do for buyers, at no cost, so you can see which combination clears your gap with the least cash tied up.
An income shortfall on paper doesnāt have to end a purchase. Pledging and showing are legitimate, MAS-sanctioned ways to turn assets you already hold into borrowing power, not loopholes or tricks. The choice between them comes down to one thing: how much uplift you need, set against how much liquidity youāre willing to give up.
If youāre not sure which split works for your situation, thatās an easy thing to check. We compare how each of the 16 banks treats pledged and shown assets, alongside their mortgage rates, so you can see the full picture before you commit. Thereās no cost and no obligation to run the numbers.
One note on the figures above. The recognition rates, the four-year lock and the 55% TDSR limit are current as at the date of publication, and MAS rules and bank practices can change, so itās worth confirming the latest position when you apply.
