Under MAS Notice 645, a bank assessing a property loan may convert a borrower's eligible financial assets into an income stream by amortising them over 48 months. Pledged with the bank for at least four years, SGD deposits are recognised in full — $48,000 pledged adds $1,000 a month to assessable income. Left unpledged as "show funds", the same assets take a 70% haircut, so $160,000 is needed for the same $1,000. That 3.3× exchange rate between locking money up and merely displaying it is the entire subject of this guide.
The rule in one formula
The eligible list is broader than most borrowers expect: SGD notes and deposits, stocks, unit trusts, business trusts, debentures and bonds, gold, foreign-currency deposits and structured deposits. Two caveats travel with it. First, the haircuts are floors — individual banks decide which assets they accept and how conservatively to value them, and acceptance of equities and foreign-currency deposits varies widely across lenders. Second, the recognition feeds the same TDSR arithmetic as salary: 55% of total recognised income, minus existing debts, must cover the instalment at the 4% stress rate.
How much do you need? A worked example
Worked illustratively: a 48-year-old borrower earning $14,000 of fixed monthly income, no other debts, wants a $1.5 million loan (75% of a $2 million private property). Age caps the tenure at 17 years (to 65), and the loan is assessed at the 4% stress rate:
| Line | Amount |
|---|---|
| Monthly instalment — $1.5M at 4%, 17 yrs | $10,146 |
| Income required (instalment ÷ 55%) | $18,447 |
| Assessable income | $14,000 |
| Monthly shortfall | $4,447 |
| Route A — pledge only (SGD deposits, × 48) | $213,461 |
| Route B — show funds only (× 48 ÷ 0.30) | $711,536 |
| Route C — pledge $100,000, covers $2,083/mo… | $100,000 |
| …plus show funds for the remaining $2,364/mo | $378,202 |
Three readings. First, the shortfall itself is modest — 24% of the requirement — yet the show-funds-only route demands $711,536, nearly half the loan being sought; the 70% haircut is punishing at scale. Second, the combination route is why the mechanism is usable in practice: pledging $100,000 the borrower can genuinely spare cuts the show-fund requirement by almost half, to $378,202. Third, age drives the whole table — the same borrower at 38 would have a 27-year tenure, an instalment near $7,700, and no shortfall at all. Asset recognition is disproportionately a tool for older borrowers whose tenure cap, not salary, creates the gap.
Pledged or unpledged: which route fits which borrower?
Pledging is capital-efficient but binding: the assets sit with the lending bank for 48 months, and withdrawing them early triggers a TDSR reassessment — with an asset top-up or partial loan recall if the ratio no longer passes. It suits borrowers holding deposits they demonstrably will not need: matured savings, a bonus pool, sale proceeds parked after an HDB sale. Showing funds keeps the money in your hands and invested, but demands roughly 3.3× the balance and is verified twice — at application and again before disbursement; moving the funds between the two checkpoints can void the approval. Most real cases blend the two, which is the split the pledge/unpledge calculator solves: enter what you are willing to lock up, and it returns the show funds needed on top.
Common mistakes and edge cases
Treating the patch as a cure. Recognition changes the assessment, not the instalment. The worked borrower still pays roughly $10,146 a month (less at their actual package rate) out of $14,000 of income — a razor-thin margin that assets on deposit do not widen. The honest first move is to re-run the quantum in the affordability calculator and ask whether a smaller loan, a cheaper unit from the budget matcher, or clearing a car loan (each $500/month of debt cleared restores roughly $100,000 of capacity) solves the problem without locking up capital.
Pledging money that has a job. Renovation budgets, the next progressive-payment stage on a building unit (see the payment schedule), a business's working capital — pledging funds that will be needed inside four years converts a financing convenience into a forced-repayment risk.
Assuming every bank plays. MAS permits recognition; it does not compel it. Some banks accept only SGD deposits, some apply steeper internal haircuts to equities, some decline the mechanism entirely. Shop the policy alongside the rate.
Forgetting variable-income interactions. The 30% haircut on bonuses and commission and the asset haircuts stack in the same assessment. A commission-heavy earner planning to close the gap with assets should compute the shortfall on the discounted income first — the calculator applies both.
Where the current numbers live
The parameters here — 55% TDSR, the 4% stress floor, the 48-month amortisation and the haircut tiers — are MAS settings that move with policy reviews. The live computation is maintained in the pledge/unpledge calculator; the income-only baseline lives in the affordability calculator and the TDSR guide's lookup tables; and the duty bill on the purchase itself is the stamp duty calculator's job. Borrowers whose gap comes from property equity rather than income should read the equity term loan guide — remembering that cash-out funds cannot legally purchase residential property.
Verdict: a bridge for asset-rich, tenure-poor borrowers
Pledging exists for a specific, legitimate profile: the borrower whose balance sheet is strong but whose assessed income — compressed by age-capped tenure, the variable-income haircut, or a recent career change — undersells their real capacity. For that profile, $48,000 per $1,000 of monthly shortfall is a fair, mechanical price, and the pledge simply parks money that was idle anyway. For the borrower whose shortfall reflects a loan genuinely too large for their cash flow, the same mechanism is a way to get approved for a mortgage that will hurt — and the bank's reassessment right means the assets are not truly liquid for four years. Run the shortfall in the calculator, then decide which profile you are.
Frequently asked questions
What does pledging assets mean?
Placing eligible financial assets — most commonly a fixed deposit — with the lending bank for at least 48 months. The bank then counts the pledged amount ÷ 48 as monthly income in the TDSR assessment, with no haircut for SGD deposits.
Pledged vs unpledged — what's the difference?
Pledged assets are committed for 4 years and recognised at full value (SGD deposits) or 70% (other assets). Unpledged show funds stay in your control but only 30% counts — the same gap takes roughly 3.3× more money to close.
How much do I need to pledge?
Monthly shortfall × 48. Short $1,000 a month: pledge $48,000, or show about $160,000. Short $4,447, as in this guide's worked example: pledge $213,461, or show $711,536.
Which assets are eligible?
Under MAS Notice 645: SGD notes and deposits, stocks, unit trusts, business trusts, debentures and bonds, gold, foreign-currency deposits and structured deposits. Each bank chooses which it actually accepts.
What if I withdraw pledged assets early?
The bank reassesses the TDSR without them and can require an asset top-up or partial loan repayment if the ratio fails — pledge only money you will not need for four years.
When are show funds checked?
Typically at application and again before disbursement. They are not locked, but the balances must still be there at both checkpoints.
Does pledging change my repayment?
No. It changes the assessment only — the instalment is identical to what an income-qualified borrower pays. That is exactly why a large shortfall deserves an honest affordability check first.

Methodology & sources. Recognition mechanics per MAS Notice 645 (eligible financial assets, 48-month amortisation, haircut tiers); assessment framework per the MAS TDSR rules (55% threshold, 4% medium-term stress rate, 30% variable-income haircut). The worked example mirrors the default case in our pledge/unpledge calculator so the two can be cross-checked line by line.
Disclaimer. All figures are illustrative estimates for education — not financial advice and not a promise of loan approval. Individual banks decide which assets they accept, apply their own valuations and internal policy, and may decline asset recognition entirely. Pledged assets are committed for 48 months and early withdrawal can trigger loan reassessment. Speak with your bank or a licensed mortgage adviser for a personalised computation.
