Correspondent banking and nostro/vostro accounts

Correspondent banking gives one financial institution access to services through another. Nostro and vostro describe an account from different institutions’ perspectives.

General information only, not legal, compliance, or other professional advice. Does not confirm compliance.

One institution serves another

A correspondent financial institution provides banking services to a respondent financial institution in another country. The respondent can use these services for its customers.

Services can include payments, foreign exchange and trade finance. The relationship can exist between related institutions.

The same account, two perspectives

A vostro account is an account the correspondent provides to the respondent under the relationship.

Nostro describes an institution’s account in foreign currency at another institution. In a matching arrangement, the respondent’s nostro is the correspondent’s vostro.

The function matters. A different account label does not remove an applicable legal duty.

One account, two viewpoints
  • Bank A: nostro

    A holds its foreign-currency account at Bank B.

  • Bank B: vostro

    B provides and holds the account for A.

One account, two viewpoints

In the fictional arrangement, both labels refer to the same account. The label changes with the institution’s viewpoint.

Separate evidence questions. An answer to one does not settle the others.

Australian due diligence conditions

Where section 100 supplies the required geographical link, section 96 applies to relationships that involve a vostro account.

Before entry, the institution needs a due diligence assessment, its written record and senior-officer approval. Ongoing assessments and records are also required.

The shell-bank prohibition has a wider account scope. It is not limited to relationships with a vostro account.

Example: access to a foreign currency

In a fictional arrangement, Bank A holds a foreign-currency account at Bank B overseas. A uses the account for customer payments.

A describes the account as its nostro. B describes the account held for A as a vostro.

These labels describe the account relationship. They do not identify every underlying customer or replace the required risk assessment.
