Hey there, it is not tied to any bank. From their FAQ,

Singlife Account is an insurance savings plan that credits interest and offers flexibility to make top ups and withdrawals (using FAST with a bank account) with no lock in and charges.

The Singlife account provides insurance coverage to policyholders in the event of death and terminal illness. It is neither a bank savings account nor a fixed deposit.

They are, however, a direct life insurer licensed by the Monetary Authority of Singapore (MAS) and all Singlife policies, including the Singlife Account are covered under the Policy Owners’ Protection (PPF) Scheme administered by Singapore Deposit Insurance Corporation (SDIC)​​​
