The bank's latest plans include cutting its cost base to below 15.5 billion francs in the medium term versus an annualized 16.8 billion this year based on first-half numbers.
It said it will give more details on how to do this with third-quarter results.
The bank has previously said it aimed to bring cost savings forward, speeding up measures introduced as part of its reorganization in November targeting 1.0 billion to 1.5 billion francs in annual structural cost savings by 2024.
It has also said an IT overhaul could generate some 800 million francs in cost savings in the medium term, including 200 million francs in each of the years 2022 and 2023.
CFO Mathers on Wednesday said cost-cutting would cover the entire group, not just IT. He gave no details on job cuts.
The bank's key capital ratio is now 13.5% of risk-weighted assets, matching its near-term target, versus market expectations of 13.6%. It is below its 2024 goal of more than 14% and first-quarter 13.8%.
"I have been CFO for 12 years and I had much, much, much lower capital ratios than this in the course of my time so this does represent still one of the highest capital ratios," said Mathers, noting a second-half CET1 capital ratio aim of 13% to 14% in an uncertain environment.
