Best High-Yield Savings Accounts in Singapore
The 'best' account depends entirely on which bonus requirements you can realistically meet each month — not the headline rate.
Why the headline rate is misleading
Singapore banks advertise a maximum effective interest rate (EIR) — often an eye-catching figure — that only applies if you meet every bonus condition simultaneously, on your full eligible balance. Salary crediting, a minimum card spend, GIRO bill payments, and an investment or insurance purchase are common conditions. Meet only one or two, and your blended rate can be a fraction of the advertised maximum.
What actually drives your effective rate
Requirements you can sustain
The right account is the one whose bonus conditions match habits you'll keep up every month without straining your spending — chasing a marginally higher rate that requires an unsustainable card spend usually isn't worth it.
The balance cap
Every account caps how much balance earns bonus interest — commonly $50,000–$100,000. Any amount above that cap typically earns only the base rate, sometimes under 1%. Large balances split across two accounts can sometimes out-earn concentrating everything in one, once you account for each account's cap.
How often rates change
Banks revise bonus tiers and base rates every few months in response to prevailing interest rate conditions and competitive pressure. An account that was best a year ago may no longer be — it's worth rechecking your effective rate periodically rather than assuming it's static.
How to compare accounts properly
Rather than comparing headline rates, plug your actual balance and which requirements you can realistically meet into the High-Yield Savings calculator. It computes your true effective rate across major Singapore banks (OCBC 360, UOB One, DBS Multiplier, and more) given your specific inputs — which is the only fair way to compare, since the "best" account is genuinely different for different people.
Interest rates and bonus conditions change frequently — this guide describes how these accounts work structurally, not current specific rates. Always verify current rates and terms directly with the bank before making a decision.

Frequently Asked Questions
Why is the advertised interest rate not what I actually earn?+
Singapore high-yield accounts advertise a maximum effective interest rate (EIR) that only applies if you meet every bonus condition — salary crediting, card spend, GIRO payments, and more — on your full balance up to the cap. Meeting fewer conditions earns a lower blended rate.
Does a higher balance always mean more bonus interest?+
No — each account caps the balance eligible for bonus interest, typically $50,000-$100,000. Any amount above that cap earns only the base rate (often under 1%), so spreading large balances across accounts can sometimes beat concentrating it in one.
How often do these accounts change their rates and requirements?+
Frequently — banks revise bonus tiers and base rates every few months in response to interest rate conditions and competition. It's worth rechecking your effective rate periodically rather than assuming it stays constant.
