An invested loan is money you borrow and then put into the market hoping the return beats the interest you pay. People reach for it when rates look cheap and a fund or stock looks hot. The trap is simple: an unsecured personal loan in Singapore charges an effective interest rate (EIR) of roughly 3.2% to over 17% p.a. in 2026, and your investment has to clear that hurdle every single year, before tax and before any loss, just to break even. This guide runs the actual maths on invested loans, splits the unsecured route from the secured portfolio-financing route the private banks use, shows where the margin-call risk hides, and sets out the narrow cases where borrowing to invest is defensible rather than reckless.
There are two completely different products hiding under the same phrase, and confusing them is how people lose money. The first is an ordinary unsecured personal loan that you happen to pour into investments. The bank does not know or care what you do with the cash; it prices you on income and credit record, hands over a lump sum, and you decide to buy a fund instead of fixing the kitchen. The second is a secured investment loan, also called portfolio financing or Lombard lending, where you pledge assets you already own and borrow against them at a far lower rate.
The distinction matters because the cost and the risk are not even close. An unsecured loan is expensive but the lender cannot touch your portfolio if it drops. A secured loan is cheap but a falling market can trigger a forced sale of your own assets at the worst possible moment. Read the section on secured loans and unsecured loans if those terms are fuzzy, because the whole decision turns on them.
Personal loan rates in Singapore look seductive on the billboard and sober on the contract. The advertised figure is a flat rate; the number that actually leaves your account is the EIR, which roughly doubles the flat rate because you repay principal monthly while interest is still charged on the original sum. DBS, for example, advertises from 1.48% p.a. but states the matching EIR as 3.22% p.a., and a thinner credit profile pushes that far higher (as of June 2026, per the DBS Personal Loan page).
Here is the figure that kills most invested-loan plans. For a borrower whose annual income sits below S$30,000, a five-year personal loan can run around 11% p.a. flat, which works out to an EIR near 20% p.a. To break even on borrowed money costing 20% a year, your investment must return more than 20% a year, every year, with zero drawdown. Almost nothing safe does that. A global equity index has historically returned roughly 7% to 10% a year over long stretches, and even that comes with years where it falls 20% or more.
| Lender / type | Advertised flat rate | Typical EIR | Processing fee | Notes |
|---|---|---|---|---|
| DBS Personal Loan | from 1.48% p.a. | from 3.22% p.a. | 1% | EIR rises sharply for lower income / thinner credit |
| GXS FlexiLoan (digital) | from 1.08% p.a. | from 2.02% p.a. | None | No processing fee; rate is profile-based |
| CIMB CashLite | varies | varies | None | Marketed as zero processing fee |
| Lower-income / 5-yr loan | ~11% p.a. | ~20% p.a. | 1% | The realistic rate many applicants actually get |
| Licensed moneylender | up to 4% per month | from ~22.56% p.a. | up to 10% | MAS-capped; far too expensive to invest with |
If you already hold a portfolio, the cheaper and more honest version of an invested loan is to borrow against it. HSBC Wealth Lending and CIMB Portfolio Financing both let you pledge assets and draw a credit line at rates tied to the loan currency rather than your credit score. Because the bank holds collateral it can sell, the rate is a fraction of an unsecured loan, and there are often no processing or annual fees on the CIMB facility (as of June 2026).
The lever here is the advance ratio, the share of an asset's value the bank will lend against. HSBC quotes up to 95% on investment-grade bonds and SGD or foreign time deposits, up to 90% on unit trusts, and up to 70% on equities, with at least a 10% reduction on cross-currency positions (HSBC Wealth Lending, June 2026). HSBC's Lombard lending lets qualifying clients leverage up to three times their effective credit limit. That power cuts both ways, which the next section explains.
When the assets you pledged fall in value, the advance ratio falls with them, and your outstanding loan can suddenly exceed your credit limit. The bank then issues a margin call. CIMB's own terms are blunt: if the market moves against you, you may lose your initial margin and still incur further liability, the bank can call on you to top up by substantial amounts at short notice, and it can sell your collateral without notice and change the margin requirement at any time.
That is the structural danger of leverage. A 70% advance ratio means a roughly 30% market drop can wipe out your equity entirely, and a forced sale locks in the loss right at the bottom. Understanding loan-to-value and how it shifts with price is the difference between using portfolio financing and being used by it.
Borrowing to invest only makes sense if the expected after-tax return clears the loan's EIR by a margin wide enough to pay you for the risk. Singapore has no capital gains tax, which helps, but the loan interest is paid in certain dollars while the investment return is a hope, not a promise. The honest comparison is the loan EIR against a realistic, not optimistic, return.
Run two cases. On an unsecured loan at a 3.22% EIR, an index fund returning 7% a year leaves a positive spread, but a single bad year can swing it negative and you still owe the fixed instalment. On the same loan at a 20% EIR, no mainstream investment reliably clears the bar, so the plan loses money in expectation. Model your own numbers with the compound interest calculator and compare leaving cash in a fixed deposit using the FD vs investing calculator before you commit a cent.
There is a narrow band where invested loans are rational rather than a gamble. It needs a genuinely low EIR, an investment whose expected return clears that EIR with room to spare, an emergency fund that covers the instalments even if your income stops, and a temperament that will not panic-sell in a 30% drawdown. Most people fail at least two of those tests.
The cleaner alternative for nearly everyone is to skip the loan and invest spare cash on a schedule. Dollar-cost averaging into a low-cost fund removes the interest hurdle entirely, and the difference compounds. Our guide on how to start investing in Singapore walks through the no-leverage path, and the piece on REIT investing for working adults shows an income-focused route that does not require borrowing.
For most people, no. An unsecured personal loan's EIR runs from about 3.2% to over 17% p.a., and your investment must beat that every year just to break even. Borrowing to invest only makes sense at a genuinely low secured rate, with a return that clears the EIR comfortably and a cash buffer to cover the instalments.
An unsecured personal loan needs no collateral, costs more, and the bank cannot seize your portfolio if it falls. Portfolio financing (or Lombard lending) is secured against assets you already own, costs far less, but a market drop can trigger a margin call that forces a sale of your own holdings at the worst time.
When the assets you pledged for a secured loan fall in value, your loan can exceed your credit limit. The bank issues a margin call, requiring you to top up cash or assets at short notice. If you cannot, the bank can sell your collateral without notice, locking in your loss right at the bottom of the market.
It depends on the advance ratio for each asset. As of June 2026, HSBC Wealth Lending quotes up to 95% against investment-grade bonds and time deposits, up to 90% against unit trusts, and up to 70% against equities, with a reduction for cross-currency positions. Higher leverage means a smaller market drop can wipe out your equity.
