How crypto lending pools work, and why MAS is cautious
Last updated: September 2026
DeFi lending refers to decentralised finance protocols that let users supply cryptocurrency to a shared liquidity pool to earn interest, while borrowers post over-collateralised crypto to draw a loan from that pool, with interest rates set algorithmically rather than by a bank.

Key Takeaways
- DeFi lending replaces a bank intermediary with smart contracts on a blockchain, matching lenders and borrowers through pooled liquidity rather than individual loan agreements.
- Borrowers must post collateral worth more than the loan itself, because DeFi protocols have no way to check creditworthiness or pursue legal recourse.
- Interest rates float algorithmically based on how much of the pool is currently borrowed, rising as more of the pool is lent out.
- MAS has repeatedly warned that DeFi lending carries smart contract risk, no deposit insurance, and no recourse if a protocol is hacked or a stablecoin de-pegs.
- Singapore-licensed Digital Payment Token service providers face restrictions on offering retail customers access to lending or staking-like yield products without clear risk disclosures.

What Is DeFi Lending?
DeFi lending runs on smart-contract-based protocols deployed on a blockchain such as Ethereum, with no bank, no credit check, and no human loan officer involved. Everything, from accepting deposits to issuing loans to liquidating collateral, is governed entirely by code that anyone can inspect.
The core mechanism is a shared liquidity pool. Lenders, often called suppliers, deposit crypto into the pool and receive interest-bearing tokens representing their share of it. Borrowers post collateral and draw a loan directly from that same pool, paying interest that flows back proportionally to the suppliers.
In Singapore, MAS has taken a cautious, consumer-protection-first stance on DeFi more broadly, drawing a clear line between institutional or wholesale DeFi experimentation, such as its own Project Guardian initiative, and retail access to DeFi products, which is subject to much stricter warnings and, in some cases, restrictions on how licensed platforms can market these products.
How Does It Work in Singapore?
Over-collateralisation is central to how DeFi lending manages risk. Because there is no way to run a credit check on a blockchain address, borrowers typically must post 120% to 150% or more of the loan value in collateral. If that collateral’s value falls, because the underlying crypto price drops, the position can be automatically liquidated by the smart contract to protect the pool’s lenders.
Interest rates in a DeFi lending pool are not fixed by a bank; they adjust automatically based on the pool’s utilisation rate, the percentage of supplied funds that are currently borrowed out. When utilisation is high, rates rise for both borrowers, discouraging further borrowing, and lenders, rewarding them for tying up their liquidity.
For Singapore-based users specifically, there are additional layers to consider. MAS’s Digital Payment Token guidelines restrict how licensed DPT service providers can market lending or staking-like products to retail customers, requiring explicit risk disclosures. However, many DeFi protocols are accessed directly by users from offshore platforms with no Singapore licence at all, meaning they sit entirely outside MAS’s regulatory perimeter and offer no local recourse if something goes wrong.
A further nuance worth understanding is flash loan risk, a DeFi-specific mechanism where a loan is borrowed and repaid within a single blockchain transaction with no collateral at all. While this doesn’t directly expose an ordinary depositor to losing their own funds through borrowing, flash loans have been used to manipulate pool prices and drain liquidity from poorly designed protocols, which is part of why protocol due diligence matters just as much as understanding the basic lending mechanics.
DeFi Lending Example
An investor deposits the equivalent of S$10,000 in a stablecoin into a DeFi lending pool and earns a variable annual yield that might range anywhere from 2% to 8%, depending on the pool’s utilisation at any given time. Separately, a borrower who wants S$5,000 in cash without selling his existing crypto holdings posts S$8,000 worth of Ethereum as collateral, a 160% collateralisation ratio, and borrows S$5,000 in stablecoins from the same pool, paying a floating interest rate. If the value of his Ethereum collateral then drops sharply and his collateralisation ratio falls below the protocol’s liquidation threshold, the smart contract automatically sells enough of his collateral to repay the loan, with no grace period or human intervention.
Advantages of DeFi Lending
- Lets crypto holders earn yield on otherwise idle holdings, or borrow against them, without selling and triggering a taxable disposal or giving up potential future upside.
- Operates continuously with instant settlement, unlike traditional bank lending, which involves credit checks, paperwork, and multi-day processing.
- Is fully transparent by design, since anyone can inspect the smart contract code and see the pool’s total liquidity, utilisation rate, and interest rate formula directly on-chain.
- Is globally accessible in principle, allowing anyone with a compatible crypto wallet to participate without needing a bank account or credit history.
Risks and Limitations
- Smart contract bugs or exploits have led to significant fund losses across the DeFi sector historically, and there is no deposit insurance or central bank backstop for a failed or hacked protocol.
- Automatic liquidation during a sharp crypto price drop can wipe out a borrower’s collateral quickly, often faster than the borrower can react to top it up.
- Stablecoins used in many lending pools have occasionally lost their peg to their intended value, disrupting pool valuations and potentially triggering cascading liquidations.
- MAS does not directly regulate most DeFi protocols, especially offshore ones, so Singapore users generally have no formal recourse if a platform is hacked, exit-scams, or freezes withdrawals.
- Tax treatment of DeFi lending income in Singapore is not always straightforward — interest-like returns may be treated differently depending on whether the activity is viewed as investment income or as a trade, and users should keep detailed records of their transactions in case IRAS requires clarification.
DeFi Lending vs a Bank Fixed Deposit
The yield on offer in DeFi lending comes with a fundamentally different risk and protection profile compared to a familiar bank product.
| Feature | DeFi Lending Pool | Bank Fixed Deposit |
|---|---|---|
| Yield | Variable, driven by pool utilisation, can range widely | Fixed rate, set upfront for the deposit tenure |
| Protection | No deposit insurance; exposed to smart contract and de-peg risk | Covered by the Singapore Deposit Insurance Corporation, up to the insured limit |
| Access | Available 24/7, permissionless, via a compatible crypto wallet | Bank operating hours or online banking, requires a bank account |
| Regulatory oversight | Largely outside MAS’s regulatory perimeter, especially offshore protocols | Fully regulated bank product under MAS supervision |

The Bottom Line
DeFi lending offers real yield and borrowing flexibility for crypto holders, but it swaps a bank’s credit checks and deposit insurance for smart contract code and over-collateralisation. Anyone using it in Singapore should treat it as a fundamentally uninsured, unregulated activity, not a higher-yielding substitute for a savings account.
