Addressing Europe’s Defence Financing Challenges
Defence financing in Europe has become a critical issue as the continent faces unprecedented geopolitical pressures and budgetary constraints. The demand for increased military spending, driven by ongoing conflicts and evolving security threats, has exposed significant challenges in the traditional methods of funding defence initiatives.
Historically, defence has been treated as a public good, with costs shouldered predominantly by national governments. However, the current scale of required investment is pushing the limits of what national budgets can realistically absorb, especially in regions grappling with aging populations and growing welfare obligations. The need for a new approach to defence financing in Europe is now urgent and unavoidable.
Growing Pressures and Political Realities
The war in Ukraine has highlighted Europe’s military vulnerabilities and forced leaders to confront the realities of collective security. Additionally, pressure from the United States—particularly under President Donald Trump—has intensified the urgency for European nations to meet and even exceed NATO defence spending commitments. With some stakeholders recommending defence expenditures as high as 5% of gross domestic product, Europe faces not just a single challenge but a complex structural shift in security requirements.
Energy security further complicates this landscape, intertwining with defence concerns and reinforcing the need for comprehensive solutions. These factors have culminated in a widespread consensus: traditional, government-led funding models are insufficient for Europe’s evolving defence needs.
Capital Markets and Private Investment
Given the constraints of national budgets—even with relaxed fiscal rules—Europe must look beyond government borrowing to bridge the defence investment gap. This is where capital markets and private investment become essential. At a recent OMFIF Defence Funding Forum, experts from finance, defence, and policy sectors explored innovative strategies to attract private capital into the defence sector.
The case for private investment extends beyond fiscal necessity. Defence spending often yields significant economic spillovers, particularly through dual-use technologies in artificial intelligence, communications, and advanced materials. Despite the potential, European start-ups and small-to-medium enterprises (SMEs) in the defence supply chain are frequently financed by American venture capital, due to a lack of scalable European alternatives. By developing the right frameworks, Europe can harness private capital to boost investment in digital technologies and research and development within the defence sector.
Overcoming Fragmentation in Procurement
One of the largest inefficiencies identified at the forum is the fragmentation of European defence procurement systems. Each country maintains its own approach, causing delays and complicating collaboration across borders. Addressing this fragmentation will require both political will and innovative financial instruments specifically designed for defence financing in Europe.
The Emergence of Defence Bonds
A promising development in defence financing in Europe is the introduction of defence bonds, similar in structure to green bonds. For example, French institutions like Bpifrance and BPCE have pioneered these bonds to channel funds to SMEs and supply chain firms active in defence. These bonds feature accountability mechanisms to ensure proceeds are used as intended and have already attracted significant investor interest, with early issues being oversubscribed.
However, defence bonds face unique challenges. Unlike green bonds, which benefited from years of framework development and growing investor confidence, defence bonds are still in their nascent stage. Liquidity concerns persist, as the investor base is not yet broad enough to support a dynamic secondary market. Additionally, ethical considerations about the nature of defence investment remain unresolved for some institutional investors.
Innovative Institutional Solutions
The OMFIF Forum showcased several new initiatives designed to tackle Europe’s defence funding gaps. The Security Action for Europe programme, for instance, utilizes EU-level loans to accelerate member state investments in line with NATO goals, focusing on strategic joint procurement. Running through 2030 with financing horizons up to 45 years, this programme complements national budgets by providing long-term structural support.
Another key effort is the Multilateral Defence Mechanism, led by the UK, Netherlands, and Finland, which aims to pool resources for joint long-term projects, standardize procurement tools, and support SMEs that struggle to access traditional financing channels. Most ambitiously, a proposal for a dedicated Defence, Security and Resilience Bank has gained traction. This institution would specialize in commercial bank lending to defence supply chains, operating outside the restrictive frameworks that hinder current defence financing in Europe while maintaining robust governance standards.
Looking Ahead: A Call for Reform
Despite these innovative approaches, no single instrument can solve the complexities of defence financing in Europe. To avoid fragmented efforts and suboptimal outcomes, European governments must commit to building purpose-built financial architectures that make joint procurement a standard practice. By viewing defence spending as a productive investment with significant economic multipliers, rather than a fiscal burden, Europe can realign how governments, investors, and credit agencies assess and support sovereign borrowing for defence initiatives.
Only with decisive action and comprehensive strategies can Europe ensure its security and generate the economic growth necessary to sustain it in the long term.
