Economic Note: What to make of proposed bank capital requirements

  • The RBNZ has proposed increased capital requirements for NZ banks to bolster financial system resilience.  Other global regulators are raising (or are proposing to raise) capital requirements.
  • Higher capital ratios are expected to translate into a higher overall cost of NZ bank funding and higher customer borrowing rates. The range of estimates is wide, with our central estimates equating to about a 50bp impact by late 2023, with risks of a higher impact.  Interest rate impacts will be also be uneven across the economy. Bank retail deposit interest rates may also fall.
  • The full impact of higher bank capital requirements will take time to percolate through the economy, but its pending imposition is another reason why we have changed our forecast profile for the OCR, including 50bps of cuts over 2019 and the OCR then on hold at 1.25% until 2022.
