FSI Sydney: 2026: One Platform, Thousands of Agents: Mizuho's AI Strategy on AWS
Mizuho built an AWS Bedrock platform running thousands of agents, cutting proposal prep 50%.
“We have 70% faster agent development, 50% reduction in proposal prep and bankers freed up time to spend three times more with those customers.”
Mizuho Financial Group, one of Japan's three largest banks with $2T in assets, deployed a centralized AI agent platform on Amazon Bedrock and Agent Core to standardize agent development across 52,000 employees. The platform achieved 70% faster agent development and 50% reduction in proposal prep time, freeing bankers to spend 3x more time with clients. The case is notable as an enterprise-scale agentic deployment in a heavily regulated industry, with Mizuho explicitly planning a progression from 'human in the loop' toward 'human on the loop' autonomy.
