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.
