Justin Welby revealed he had spoken to City high flyers who refused to accept any blame for the banking meltdown.
He told BBC Radio 4’s Today programme: “I came across some people recently - senior members of the City, from foreign organisations - who were absolutely in denial about what happened in 2008.”
Archbishop Welby declined to give names and said British banks had begun to clean up their act.
Mr Welby, a former oil executive, has used his high profile role to slam various business sectors.
They include rip-off payday lenders, with the outspoken Archbishop vowing to drive industry heavyweight Wonga out of business by setting-up church credit unions.
But his attack backfired when it emerged in July last year that the Church of England indirectly owned a stake on Wonga.
Archbishop Welby said he was “embarrassed” about the stake, and ordered a review.
But, nearly six months on, he admitted Church Commissioners who oversee the investment hadn’t got shot of them yet.
He said: “They are working out how they can dispose of those shares”, adding it was crucial not to make a loss for pensioners.
Archbishop Welby has previously slammed Barclays, claiming the bank had “repeatedly let down society with its conduct”.
