Staley predicted with global vaccine coverage improving, much of that "spare" cash would be spent in a huge boost to the economy, unlike anything since the post-World War II boom. 

Along with the much-needed recovery for the economy at large, Staley noted the saving trend has also improved the bank's fortunes. 

"Credit losses are much, much lower and revenues are much higher… in the investment bank," he said.
