Malaysian Banking Law – Expansion of the Banker-Customer Relationship Under Common Law


Case Scenario
Global Trade Bank, a foreign non-clearing bank, regularly used Metro Clearing Bank, an English clearing bank, to collect cheques deposited by its customers. Although Global Trade Bank did not maintain ordinary retail banking transactions with Metro Clearing Bank, it continuously relied upon Metro Clearing Bank to clear cheques and process collections on its behalf.
One day, a dispute arose after a crossed cheque collected through Metro Clearing Bank was discovered to involve fraudulent transactions. Metro Clearing Bank attempted to deny liability by arguing that Global Trade Bank was merely another financial institution and not its “customer.”
At the same time, a separate issue arose involving Mr. Lim, a “walk-in” customer who visited a bank to purchase a bank draft. After completing the transaction, he accidentally left the draft on the bank counter where it was subsequently stolen. Mr. Lim argued that although he was not an account holder, the bank nevertheless owed him a duty of care while conducting the transaction.
The disputes closely resemble the principles established in Importers Co Ltd v Westminster Bank Ltd and Kehar Singh a/l Jasa Singh v The Standard Chartered Bank together with earlier banking authorities.
Applying these principles, the court would likely conclude that:
  • one bank may become a customer of another bank where regular banking services are performed between them; and
  • even a “walk-in” customer may be owed a duty of care in certain banking transactions despite not maintaining an account.
These situations demonstrate the expanding judicial understanding of customer relationships in modern banking law.


Meaning of “Customer” in Banking Law
The banker-customer relationship forms the legal foundation of banking law because it determines the obligations owed between financial institutions and individuals.
Generally, a customer refers to a person who maintains an account with a bank or engages the bank to perform banking services. However, neither Malaysian nor UK banking legislation provides a complete statutory definition of “customer.”
Consequently, courts have developed the legal meaning of customer through judicial interpretation.
Once customer status exists, banks owe important legal obligations, including:
  • the duty of confidentiality;
  • the duty to honour valid payment instructions;
  • the duty to exercise reasonable care and skill; and
  • compliance with banking and financial regulations.
Because these obligations are significant, courts carefully determine the exact moment when the banker-customer relationship arises.


Position Under Malaysian Law
Under Malaysian law, no comprehensive statutory definition of “customer” exists.
The Financial Services Act 2013 defines a “depositor” as a person entitled to repayment of a deposit, whether the deposit was made personally or by another person. However, the Act does not define “customer.”
Similarly, the Bills of Exchange Act 1949 regulates negotiable instruments such as cheques and bills of exchange but does not define customer status.
Malaysian courts therefore continue to rely heavily upon English common law principles together with local judicial authorities.


Position Under UK Law
The United Kingdom similarly provides no statutory definition of “customer.”
Neither the Bills of Exchange Act 1882 nor the Cheques Act 1957 defines the term.
English courts therefore developed judicial principles to determine:
  • who qualifies as a customer; and
  • when the banker-customer relationship arises.
The principal authorities include:
  • Great Western Railway Co v London and County Banking Co Ltd;
  • Robinson v Midland Bank Ltd;
  • Commissioners of Taxation v English, Scottish and Australian Bank Ltd;
  • Ladbroke & Co v Todd;
  • Barclays Bank Ltd v Okenarhe;
  • Tate v Wilts and Dorset Bank;
  • Woods v Martins Bank Ltd; and
  • Importers Co Ltd v Westminster Bank Ltd.


Traditional Judicial Principles on Customer Status
Earlier judicial authorities established several foundational principles regarding customer status.
Great Western Railway Principle
In Great Western Railway Co v London and County Banking Co Ltd, the court held that casual banking services alone are insufficient to establish customer status.
The House of Lords emphasised that some form of account or recognised banking relationship is necessary.


Robinson v Midland Bank Ltd Principle
In Robinson v Midland Bank Ltd, the court explained that the chief criterion for customer status is the existence of an account through which banking transactions are conducted.


Commissioners of Taxation Principle
In Commissioners of Taxation v English, Scottish and Australian Bank Ltd, the House of Lords clarified that duration of the relationship is not essential.
A person may become a customer immediately once:
  • an account is opened; and
  • money is accepted into that account.


Ladbroke & Co v Todd Principle
In Ladbroke & Co v Todd, the court held that customer status may arise even before a cheque has cleared.


Barclays Bank Ltd v Okenarhe Principle
In Barclays Bank Ltd v Okenarhe, the court held that a person is not a customer where the bank merely performs a casual service without any recognised account relationship.


Tate v Wilts and Dorset Bank Principle
In Tate v Wilts and Dorset Bank, the court clarified that mere intention to open an account is insufficient to establish customer status.


Woods v Martins Bank Ltd Principle
In Woods v Martins Bank Ltd, the court recognised that contractual arrangements and accepted banking instructions may establish customer status even before formal account opening.


Importers Co Ltd v Westminster Bank Ltd Principle
An important expansion of the banker-customer relationship occurred in Importers Co Ltd v Westminster Bank Ltd.
Facts
An English bank acted as agent for a foreign bank and regularly collected cheques drawn on other English banks. The proceeds of these cheques were credited to the foreign bank for transactions involving the foreign bank’s customers.
One legal issue before the court was whether the foreign bank qualified as a “customer” of the English bank for purposes of statutory protection under section 82 of the Bills of Exchange Act 1882.
Held
The Court of Appeal held that the English bank was collecting the crossed cheques for a customer within the meaning of the legislation.
Atkin LJ explained:
“… it seems to me that if a non-clearing bank regularly employs a clearing bank to clear its cheques, the non-clearing bank is the ‘customer’ of the clearing bank.”
Similarly, Bankes LJ stated that where cheque collection business is regularly conducted between two banks, the bank receiving the service may properly be regarded as the customer of the other bank.
The case therefore established that:
  • a bank itself may qualify as a customer of another bank; and
  • regular banking arrangements between banks may create a banker-customer relationship.


Legal Analysis of Importers Co Ltd Case
The decision in Importers Co Ltd v Westminster Bank Ltd significantly expanded the traditional concept of customer status.
Earlier authorities focused mainly upon individual account holders. However, Importers recognised that banking relationships may also exist between financial institutions themselves.
The case demonstrates that:
  • customer status depends upon the functional banking relationship between parties; and
  • a bank performing regular banking services for another bank may owe duties similar to those owed to ordinary customers.
This reflects commercial realities because modern banking systems depend heavily upon:
  • interbank clearing arrangements;
  • correspondent banking relationships; and
  • international cheque collection services.


Kehar Singh Principle
An important Malaysian development occurred in Kehar Singh a/l Jasa Singh v The Standard Chartered Bank.
Facts
The plaintiff was a “walk-in” customer who did not maintain an account with the bank. He visited the bank to purchase a bank draft and subsequently left the draft unattended on the bank counter, where it was lost.
He later claimed compensation from the bank for the loss.
Held
The Supreme Court held that liability should be apportioned equally because both:
  • the bank; and
  • the plaintiff
had been negligent.
Importantly, although the plaintiff was merely a “walk-in” customer and not an account holder, the court nevertheless treated him as a customer for purposes of imposing a duty of care upon the bank.


Legal Analysis of Kehar Singh Case
The decision in Kehar Singh a/l Jasa Singh v The Standard Chartered Bank demonstrates a flexible judicial approach toward customer protection.
Unlike earlier authorities which strongly emphasised account relationships, the court recognised that:
  • certain banking transactions themselves may create sufficient proximity; and
  • banks may owe duties of care even toward temporary or walk-in customers.
The case therefore broadens the traditional understanding of customer relationships in Malaysian banking law.


Combined Judicial Principles
When all the authorities are read together, the following principles emerge:
  1. Casual banking services alone are generally insufficient.
  2. Some form of recognised banking relationship is normally necessary.
  3. Duration of the relationship is irrelevant.
  4. Customer status may arise immediately once:
    • an account is opened;
    • funds are accepted;
    • banking instructions are accepted; or
    • contractual banking arrangements arise.
  5. One bank may become the customer of another bank.
  6. In certain circumstances, even a walk-in customer may be owed duties of care by the bank.


Critical Analysis
The judicial development of customer status demonstrates increasing commercial flexibility.
Earlier authorities adopted a restrictive approach focused heavily upon account relationships. However, later cases such as:
  • Woods v Martins Bank Ltd;
  • Importers Co Ltd v Westminster Bank Ltd; and
  • Kehar Singh a/l Jasa Singh v The Standard Chartered Bank
expanded the concept of customer status to reflect modern banking realities.
These developments are commercially practical because modern financial systems involve:
  • interbank clearing systems;
  • correspondent banking;
  • fintech platforms;
  • electronic fund transfers; and
  • temporary banking transactions involving non-account holders.
Nevertheless, excessive expansion of customer status may expose banks to wider liabilities and increased operational risks.


Practical Importance
The banker-customer relationship remains highly important because banks owe significant duties once customer status arises.
Examples include:
  • a person opening an account for cheque collection immediately becomes a customer;
  • one bank may become a customer of another bank for cheque clearing purposes;
  • contractual banking instructions may create customer status even before formal account opening; and
  • a walk-in customer may still be owed duties of care during banking transactions.
Banks therefore require:
  • proper account-opening procedures;
  • strong verification systems; and
  • careful operational safeguards.


Solutions to the Case Scenario
Several measures may reduce disputes involving customer status.
1. Clear Interbank Agreements
Banks should clearly document interbank clearing relationships and corresponding duties.
2. Enhanced Customer Communication
Banks should clearly explain when customer status arises and the extent of banking obligations.
3. Strong Operational Safeguards
Banks should implement strict verification and monitoring systems during:
  • cheque collection;
  • bank draft issuance; and
  • interbank transactions.
4. Legislative Reform
Malaysia may consider introducing a statutory definition of “customer.”
5. Modern Digital Banking Regulation
Regulators should establish clearer legal frameworks governing fintech relationships and temporary banking transactions.
Had these measures been fully implemented, many disputes involving temporary, walk-in, or interbank customers could have been minimised.


Conclusion
The banker-customer relationship forms the legal foundation of banking law because it determines the obligations owed between banks and individuals.
Although Malaysian and UK legislation do not provide a complete statutory definition of “customer,” courts have developed extensive judicial principles through case law.
Cases such as Great Western Railway Co v London and County Banking Co Ltd, Robinson v Midland Bank Ltd, Commissioners of Taxation v English, Scottish and Australian Bank Ltd, Importers Co Ltd v Westminster Bank Ltd, and Kehar Singh a/l Jasa Singh v The Standard Chartered Bank collectively demonstrate that:
  • customer status depends upon the existence of a genuine banking relationship;
  • duration is irrelevant;
  • contractual and interbank arrangements may establish customer status; and
  • banks may owe duties even toward certain temporary or walk-in customers.
These principles continue to shape modern banking law despite continuing technological developments in digital finance and global banking systems.
