Westpac capital requirements increased after breaching regulatory obligations

Westpac New Zealand Limited (Westpac) has had its minimum regulatory capital requirements increased after it failed to comply with regulatory obligations relating to its status as an internal models bank.

Internal models banks are accredited by the Reserve Bank to use approved risk models to calculate how much regulatory capital they need to hold. Westpac used a number of models that had not been approved by the Reserve Bank, and materially failed to meet requirements around model governance, processes and documentation.

“This is very disappointing. Operating as an internal models bank is a privilege that requires high standards and comes with considerable responsibilities. Westpac has not met our expectations in this regard,” Reserve Bank Deputy Governor and Head of Financial Stability Geoff Bascand said.

The Reserve Bank required Westpac to commission an independent report into its compliance with internal models regulatory requirements. The report found that Westpac:

• currently operates 17 (out of 35) unapproved capital models;

• has used 21 (out of 32) additional unapproved capital models since it was accredited as an internal models bank in 2008; and

• failed to put in place the systems and controls an internal models bank is required to have under its conditions of registration.

The Reserve Bank has decided that Westpac’s conditions of registration should be amended to increase its minimum capital levels until the shortcomings and
non-compliance identified in the independent report have been remedied. Westpac’s minimum capital ratio requirements will be 6.5 percent for Common Equity Tier 1 capital, 8 percent for Tier 1 capital and 10 percent for Total capital, with the additional 2.5 percent capital conservation buffer applying. Currently, for all other locally incorporated banks capital ratios are set at, respectively, 4.5 percent, 6 percent and 8 percent, plus the 2.5 percent buffer.

In addition, the Reserve Bank has accepted an undertaking by Westpac to maintain its total capital ratio above 15.1 percent until all existing issues have been resolved. The Reserve Bank has given Westpac 18 months to satisfy the Reserve Bank that it has sufficiently addressed those issues or it risks losing accreditation to operate as an internal models bank.

“We believe the regulatory action is appropriate given the seriousness of Westpac’s non-compliance and the need to protect the integrity of the capital regime,” Mr Bascand said.

The Reserve Bank has taken into account that Westpac has not deliberately sought to reduce its regulatory capital. While there have been serious shortcomings and
non-compliance, it appears that Westpac has remained well above its required regulatory capital levels.

Westpac has confirmed that it does not dispute the findings of the independent report, that it is committed to remedying all the issues identified, and that it will maintain its total capital ratio above 15.1 percent.
