Multiple recent news reports (Source 1 and Source 12) directly state that former Barclays CEO Bob Diamond has urged or warned traditional banks to embrace blockchain technology, with one source quoting him as saying they risk being 'left behind'. This is highly credible as other sources confirm his deep involvement in the blockchain sector, including chairing a decentralized trading platform and leading a SPAC that merged with a cryptocurrency firm (Sources 5 and 6).
