Ultimate beneficial owner (UBO)

The real person who ultimately owns or controls a customer, or on whose behalf a transaction is carried out.

In plain English

Companies, trusts and other structures can hide who really benefits from them. The ultimate beneficial owner (UBO) is the natural person at the end of the ownership and control chain, including anyone who exercises ultimate effective control even without a large shareholding.

Law usually sets a threshold above which an owner must be identified, often expressed as a percentage of ownership. Where no one meets the threshold, institutions normally have to look at who exercises control, and, as a last resort, identify a senior managing official.

Why it matters to a board

Beneficial ownership gaps weaken sanctions screening, PEP identification and every other control that depends on knowing who is behind a customer.

Common mistakes

  • Stopping at a corporate shareholder instead of looking through to the person.
  • Relying on a single register or customer statement without checking it.
  • Ignoring control that does not come from shareholding, such as agreements or board rights.
