Most of the largest banks in Asia-Pacific reported a quarter-over-quarter increase in their fully loaded common equity Tier 1 ratios in the third quarter, according to a survey by S&P Global Market Intelligence.

Of the 25 banks compiled in the report, 23 reported quarter-over-quarter growth in CET1 ratios, with Chinese lenders posting the highest increments.

Ping An Bank Co. Ltd. posted the biggest improvement of 86 basis points with a ratio of 9.75%, while Mizuho Financial Group Inc. saw the biggest decline as it lost 19 basis points between the two quarters.

The survey uses a metric based on a bank's CET1 capital as a percentage of risk-weighted assets. It included Asia-Pacific banks with fully loaded CET1 ratios of at least 7% from 2019 onward under Basel III regulations, comprising a minimum 4.5% CET1 ratio and a 2.5% capital conservation buffer. Some banks may also have local capital buffer obligations.
