It typically takes 1 to 2 weeks to open a checking account in Singapore. The exact timeframe can vary depending on several factors, including the bank’s processing time, the completeness of the required documentation, and any additional checks or approvals required by the bank. Some banks may offer expedited account opening services for certain types of accounts or customers, which could potentially reduce the waiting time. Additionally, if you’re opening an account as a non-resident or a foreign company, the process may take longer due to additional compliance requirements.
