As the US refocuses and pushes allies to shoulder more of their own defence burden, Asia is emerging as an increasingly important part of the global defence buildout. What may once have looked like a series of geopolitical flashpoints is increasingly taking shape as a regional, multi-year industrial trend.

This is not only a story of increasing defence budgets. It is also a story of expanding domestic capability, firmer procurement plans and a broader listed opportunity set. Across the region, governments are responding to a tougher security backdrop with resilient defence spending growth, clear strategic priorities, and a strong push to build local industrial capacity.

Structural forces driving Asia defence

Persistent threat environment: Tensions around the Taiwan Strait, the Korean Peninsula and the India-Pakistan border continue to keep readiness high. That supports demand not only for new platforms, but also for munitions, maintenance, upgrades, training and sustainment. Once readiness requirements move up, these categories tend to become more recurring and less discretionary.

Strategic autonomy: As the US asks allies and partners in Asia to shoulder more of the burden, governments across the region are placing greater weight on self-reliance. That means more local production, more domestic qualification, more in-country maintenance and a larger role for national champions. In investment terms, it means a greater share of defence spending can remain within local industrial ecosystems rather than flowing abroad.

Policy and spending support: In several major Asian markets, stronger defence spending is now supported by formal strategy documents, updated doctrine, and longer funding horizons. That improves revenue visibility, supports capacity expansion and gives companies greater confidence to invest in production lines, inventories and supply chains. This is important because it turns a geopolitical concern into a more investable industrial theme.

Cross-sectoral synergies: Defence modernisation increasingly extends to drones, cyber, space, and other dual-use sectors. This is not just about shipbuilders or aircraft manufacturers. It is also about subsystem suppliers, enabling technologies and dual-use businesses that sit deeper in the value chain.

Country cases: different drivers, shared direction

The country cases help to show why the theme has momentum. The drivers vary by market, but the direction is consistent.

• Japan: Japan’s defence shift is increasingly policy-led, with a clearer commitment to stronger capabilities, higher spending and a more serious domestic industrial base.
• South Korea: South Korea combines industrial depth, advanced technology and export momentum, making it one of Asia’s most established defence ecosystems and an increasingly important supplier to global markets.
• India: India is accelerating defence localisation through procurement reform and Atmanirbhar Bharat, directing more spending towards local manufacturing and creating a broader domestic supply chain for future growth.

Taken together, they reinforce the same broader point. Asia defence is becoming more structural, more local and more investable.

How to capture Asia's defence investment cycle

WisdomTree Asia Defence UCITS ETF (WDAF) is designed to give investors targeted exposure to Asia Pacific ex-China companies with meaningful involvement in the defence industry. Following the successful launch of WisdomTree Europe Defence UCITS ETF (WDEF), the WisdomTree Asia Defence UCITS ETF extends that approach to another region where defence spending, strategic autonomy and industrial buildout are becoming increasingly important.

The exchange-traded fund (ETF) tracks the WisdomTree Asia Defence UCITS Index, which targets companies deriving at least 10% of their revenue from defence activities and tilts towards those with higher exposure. This creates a more focused, pure-play profile, screening out diversified conglomerates where defence is only marginal, while giving greater weight to companies more directly positioned to benefit from Asia’s military modernisation cycle.

To be eligible, companies must also meet minimum market capitalisation and liquidity requirements. The strategy further applies controversial weapons screening¹.

Each selected company is assigned an Exposure Score from 1 to 3 based on the revenue exposure to defence activities.

• Exposure Score 3: companies with > 50% revenue exposure to defence activities
• Exposure Score 2: companies with 25% to 50% revenue exposure to defence activities
• Exposure Score 1: companies with 10% to 25% revenue exposure to defence activities

The Index is weighted by market capitalisation adjusted by the Exposure Score, subject to the capping² and liquidity adjustment criteria. Companies with higher market capitalisation and Exposure Scores are assigned greater weights. The Index is rebalanced on a quarterly basis.

A closer look at the WisdomTree Asia Defence UCITS ETF portfolio

The portfolio is designed to reflect the breadth of Asia’s defence buildout while maintaining a clear focus on companies with meaningful exposure to the theme.

As shown in Figure 1, the Index includes companies across Japan, South Korea, India, Australia and Southeast Asia. It is reconstituted quarterly to reflect changes in the defence sector.

As shown in Figure 2, the strategy’s top holdings illustrate its design logic. As of late February 2026, the portfolio’s 10 largest positions, ranging from Hanwha Aerospace and Korea Aerospace Industries in South Korea to Hindustan Aeronautics, Mazagon Dock Shipbuilders and Bharat Electronics in India, represented about 66.5% of the total weight.

These companies are not just national champions. They are increasingly becoming exporters of security. Hanwha’s joint venture in Poland for missile production, India’s Cochin Shipyard expansion and Japan’s Kawasaki Heavy Industries’ global supply chain all point to Asia’s rise not only as a defence buyer, but also as a defence supplier.

Conclusion

Asia’s defence cycle is becoming more structural and more investable, driven by a tougher threat backdrop, rising strategic autonomy and deeper industrial capacity across the region. The WisdomTree Asia Defence UCITS ETF (WDAF) provides targeted, rules-based exposure to that opportunity, with a portfolio tilted towards companies with more direct defence revenue exposure.
