Key takeaways

  • Europe has entered an era of rearmament after rising uncertainty over US security guarantees and the erosion of the post-war security settlement.
  • European countries, notably Germany and France, are significantly increasing domestic military spending in response to NATO commitments and perceived threats.
  • With EU policy driving strategic autonomy and unlocking transformative investment in the sector, European defence stocks now present a generational opportunity for investors seeking long-term structural growth exposure.1

Defence stocks in Europe have shot into the spotlight as the post-war security order has been shaken, prompting European countries to boost military spending in a bid to respond to NATO commitments and achieve self-reliance amid mounting threats.

With US security guarantees increasingly uncertain, Europe is scrambling to repair decades of chronic underinvestment through a raft of massive spending measures designed to bolster neglected defensive capabilities in the face of rising geopolitical instability.

Today, most European countries are significantly increasing military spending and channelling it towards domestic defence industries, strengthening the region’s technological and industrial base.

Germany and France: Leading the rearmament push

Notably, Germany and also France are at the forefront of this rearmament drive. Germany, Europe’s biggest economy, has overhauled its fiscal rules to enable a significant increase in military expenditure, while also establishing a €500 billion special fund for infrastructure projects over the next 12 years.2 Meanwhile, France’s President Emmanuel Macron is considering leveraging the country’s Public Investment Bank to finance the defence industry, alongside plans to raise defence spending from 2.1% of GDP to 3%.3

Rearmament requires major investment

Comparing the investment levels and defence capabilities of the major global powers reveals the scale of the security disparities European countries are seeking to address. While the US currently spends 3.4% of GDP on defence and Russia 6.7%, the EU and UK spend a combined 2%. China spends less in GDP terms (1.7%), but its economic scale and sustained investment underscore the challenges facing European countries.4

While Europe has a short-term urgency to support Ukraine, it has recognised the need to spend more to boost its own security and defence, whatever the outcome of the Russia/Ukraine war.

A powerful EU response

In parallel with national initiatives, the European Union is stepping up its efforts to support the region’s rearmament drive.

A key pillar of this effort is the European Defence Fund (EDF),5 which supports companies across EU Member States in developing competitive and collaborative defence projects. The EDF has helped lay the foundation for a more integrated and strategically autonomous defence industrial base—creating powerful tailwinds for the sector and generating long-term opportunities for investors.

Building on this foundation, in March 2025 the European Commission unveiled an ambitious new defence package aimed at driving a surge in investment across the sector. Launched under the ReArm Europe Plan / Readiness 2030,6 the plan enables national defence spending of over €800 billion and empowers the Commission to raise up to €150 billion to allow member states to massively scale up their defence investments through common procurement from the European defence industry, focusing on priority capabilities.

Announcing the plan, European Commission President Ursula von der Leyen declared:

We are taking decisive action…with increased defence spending, important investments in European defence industrial capabilities. We must buy more European.

Who will be the winners?

There is no shortage of potential beneficiaries of the surge in defence spending, with Europe home to dozens of world-class companies operating in and around the sector. Previously under-the-radar national champions like France’s Thales, Germany’s Rheinmetall and Italy’s Leonardo have risen to prominence as the market has recognised their potential to benefit from higher defence spending. 

Meanwhile companies like Rolls-Royce, Airbus and BAE Systems are longtime leading lights of the global defence sector, demonstrating the breadth and quality of options in Europe for those seeking to benefit from structurally elevated security spending. 

Investors are already showing appetite for European defence exposure. Industrial ETF strategies collected €1.1bn in March, with the popularity of defence stocks largely driving this growth.7

The wider equities outlook

While investors have been scaling back their exposure to US equities this year and rotating into Europe, valuations remain attractive relative to the US stock market. 

Moreover, European equities generally offer higher dividend payout ratios compared to US stocks. For instance, the Stoxx Europe 600 offers an estimated dividend yield of 3.5%, significantly higher than the 1.5% yield of the S&P 500.8

Conclusion: A sector with the growth potential to outweigh short-term volatility9

Volatility has risen across global equity markets since trade tariffs were announced by the Trump administration, and risks of sharp moves remain with lingering uncertainty demanding vigilance from market participants.10

However, as Europe embraces a more coherent security policy, with broad support for vast additional defence spending and fiscal stimulus, European defence stocks offer investors a generational opportunity to gain exposure to a segment of the market with long-term growth potential.11

KNOWING YOUR RISK
It is important for potential investors to evaluate the risks described below and in the fund’s Key Information Document (“KID”) and prospectus available on our websites www.amundietf.com.
CAPITAL AT RISK - ETFs are tracking instruments. Their risk profile is similar to a direct investment in the underlying index. Investors’ capital is fully at risk and investors may not get back the amount originally invested.
UNDERLYING RISK - The underlying index of an ETF may be complex and volatile. For example, ETFs exposed to Emerging Markets carry a greater risk of potential loss than investment in Developed Markets as they are exposed to a wide range of unpredictable Emerging Market risks.
REPLICATION RISK - The fund’s objectives might not be reached due to unexpected events on the underlying markets which will impact the index calculation and the efficient fund replication.
COUNTERPARTY RISK - Investors are exposed to risks resulting from the use of an OTC swap (over-the-counter) or securities lending with the respective counterparty(-ies). Counterparty(-ies) are credit institution(s) whose name(s) can be found on the fund’s website amundietf.com. In line with the UCITS guidelines, the exposure to the counterparty cannot exceed 10% of the total assets of the fund. 
CURRENCY RISK – An ETF may be exposed to currency risk if the ETF is denominated in a currency different to that of the underlying index securities it is tracking. This means that exchange rate fluctuations could have a negative or positive effect on returns.
LIQUIDITY RISK – There is a risk associated with the markets to which the ETF is exposed. The price and the value of investments are linked to the liquidity risk of the underlying index components. Investments can go up or down. In addition, on the secondary market liquidity is provided by registered market makers on the respective stock exchange where the ETF is listed. On exchange, liquidity may be limited as a result of a suspension in the underlying market represented by the underlying index tracked by the ETF; a failure in the systems of one of the relevant stock exchanges, or other market-maker systems; or an abnormal trading situation or event.
VOLATILITY RISK – The ETF is exposed to changes in the volatility patterns of the underlying index relevant markets. The ETF value can change rapidly and unpredictably, and potentially move in a large magnitude, up or down.
CONCENTRATION RISK – Thematic ETFs select stocks or bonds for their portfolio from the original benchmark index. Where selection rules are extensive, it can lead to a more concentrated portfolio where risk is spread over fewer stocks than the original benchmark.
