Australia & New Zealand Banking Group Ltd. expects an increase in common equity Tier 1 capital of about A$3 billion by July 2027 after the Reserve Bank of New Zealand imposed higher capital requirements for banks in the country.

ANZ said the increase in common equity Tier 1 capital includes a management buffer of about A$1 billion. ANZ's common equity Tier 1 ratio at Sept. 30 was 11.4%, or around A$3.5 billion above the Australian Prudential Regulation Authority's stated unquestionably strong level of 10.5%.

The impact is net of about NZ$1.5 billion of profits that ANZ Bank New Zealand Ltd. has retained in 2019.

The Reserve Bank of New Zealand is requiring the country's four largest banks by assets, including ANZ Bank New Zealand, to have total capital equal to 18% of risk-weighted assets, while the remaining smaller banks will need to have total capital equal to 16% of risk-weighted assets.

As of Dec. 17, US$1 was equivalent to NZ$1.52.
