Quantum Technologies and the Geostrategic Landscape: Implications for Finance and Central Banks

Special Report

March 24, 2026

Quantum technologies, and quantum computing in particular, could completely reshape the integrity of today’s financial markets. Both through risk and opportunity channels, quantum computing is changing the game and raising the stakes. Cracking today’s cryptographic standards would undermine global payment systems and digital assets, causing the potential collapse of all current encryption systems, while quantum-enabled advances in optimization and modelling may dramatically enhance economic forecasting, monetary policy and planning. “Quantum readiness” is the next necessary step for any nation wanting to both stay safe from these projected dangers and also to make the most of the potential benefits.

This special report aims to provide a situational analysis of quantum technologies useful for senior G7 (and beyond) decision makers in finance and central banking. By examining the current landscape, as well as several scenarios, the authors outline key implications for strategic planning and action for consideration by policy leaders around the world. They structure their suggested priority interventions across three tiers: national, international and public-private collaboration, with actionable recommendations across each level.
