How Banks Work (Malaysia)
The practical guide: deposits → loans, payments, Islamic vs conventional, how rates are set, safety rails (PIDM & BNM), and what it means for you.
What banks actually do
- Hold & move money: accounts, cards, IBG/Instant Transfer, FPX, DuitNow/QR.
- Lend / finance: mortgages, personal & auto financing, business credit, cards.
- Transform risk & time: many on-demand deposits → fewer, longer-term loans.
- Create money (system-wide): new loans usually create matching deposits somewhere.
- Services: FX, wealth, custody, trade finance, merchant acquiring.
How banks earn
- Net interest/profit margin: returns on loans & securities minus deposit/funding costs.
- Fees: payments, cards (interchange), FX, wealth, account fees.
- Treasury/trading: liquidity mgmt & hedging; more relevant at larger banks.
Islamic banking: Shariah-compliant contracts (profit rate). Outcomes often feel similar to interest-based products, but structures differ.
Safety rails (Malaysia)
- PIDM deposit insurance: eligible deposits protected up to RM250,000 per depositor, per member bank (principal + interest/profit). Automatic
- Takaful/Insurance (TIPS by PIDM): eligible benefits protected up to RM500,000 (limit varies by benefit type).
- Supervision: Bank Negara Malaysia (BNM) sets capital/liquidity rules & conducts supervision and consumer protection.
How rates are set
- Policy rate (OPR): influences loan/deposit rates economy-wide.
- SBR: retail floating-rate loans use the Standardised Base Rate, linked solely to OPR. Banks add a product/risk spread.
- Fixed vs floating: fixed = payment certainty; floating = SBR (OPR) + bank spread.
Payments you actually use
- DuitNow Transfer: instant, 24/7 — send to mobile, NRIC or BRN proxies, or account no.
- DuitNow QR: one QR across banks & e-wallets; scan & pay where the logo appears.
- DuitNow Request / AutoDebit: request-to-pay & automated collections.
- FPX / IBG / RENTAS: online payments, GIRO and high-value transfers.
What happens to your deposit
You deposit RM100. The bank holds some as cash/reserves & liquid assets; the rest goes into loans/securities.
- It lends RM90 to a business; the RM90 lands as a deposit (here or at another bank).
- System-wide, loans create deposits; repayments or write-offs shrink them.
Credit risk
Borrowers may default. Banks underwrite, take collateral/guarantees, and set provisions.
Liquidity risk
Too many withdrawals at once. Banks keep high-quality liquid assets and central-bank access.
Rate risk (ALM)
Rates move. ALM hedges/positions so earnings & capital stay resilient.
Common products (what to watch)
- Home financing: floating (SBR + spread) or fixed; check lock-in & early-settlement fees.
- Term deposits: rates move with OPR & competition; mind PIDM limits per bank.
- Cards: rewards vs fees/compounding; pay in full to avoid high annualised charges.
Quick tips
- Keep total deposits with any one bank ≤ RM250k for full PIDM coverage.
- For floating loans, track OPR/SBR announcements (repayments may change).
- Use instant rails (DuitNow) for speed & confirmation.
