Fintech’s $1.5 Trillion Outlook Puts Software Security and Costs in Focus

Custom financial software handles payment, deposit, lending and investment data, making security architecture a core business requirement rather than a feature added before launch. Identity controls, encryption, access management, audit trails and regulatory compliance can materially increase build and maintenance costs. Banks’ deeper use of artificial intelligence raises the stakes further, as institutions must integrate models with legacy systems while governing sensitive data, model risk and automated decisions.

The latest report frames the opportunity against a $1.5 trillion benchmark. In May 2023, Boston Consulting Group and QED Investors forecast annual global fintech revenue would climb more than sixfold, from $245 billion in 2021 to $1.5 trillion by 2030. They projected banking-related fintech penetration of banking revenue pools to rise from 4% to 13% over the same period, underscoring why development budgets increasingly hinge on secure core modules, integration capacity and durable compliance controls.
