Headline arguments
The challenge
The post-Cold War economic order assumed that efficiency, integration and the separation of economics from security would deliver prosperity and stability. That assumption no longer holds. Strategic competition, economic coercion, technological rivalry, climate disruption and the weaponisation of trade, finance, data and supply chains have collapsed the distinction between economic policy and national security.
Across allied economies governments are responding with higher defence expenditure and renewed industrial policies. Rising spending has not translated into equivalent capability. Defence inflation, supply-chain bottlenecks, workforce shortages and persistent financing gaps all point to the same conclusion: security is no longer a question of how much governments spend, but of whether their economies can convert resources into resilience, preparedness and strategic advantage.
The defining question of the coming decades is whether democratic economies can build the institutions to transform economic strength into strategic power. The constraint is not defence finance, military expenditure or fiscal capacity. It is capability formation. It is the Productive Security gap.
Productive Security is the capacity of an economy, society or alliance to generate, sustain, adapt and mobilise the productive capabilities required to achieve long-term security objectives. It shifts security away from being understood solely through military capability or defence expenditure, and recognises that capability emerges from the interaction between innovation systems, financial systems, industrial ecosystems, supply chains, human capital, data infrastructure and Critical Social Infrastructure.
The paper introduces Open Source Economic Intelligence (OSEINT) as a framework for identifying emerging vulnerabilities, strategic dependencies and systemic risks across interconnected economic, technological, environmental and social systems. It proposes seven Bretton Woods principles, and a complementary institutional ecosystem - the Allied Defence Market, the Multilateral Defence Mechanism, and the Defence, Security and Resilience Bank - designed to convert economic strength into sustainable strategic advantage.
