Fragile Gaza Ceasefire Puts Defense ETFs in the Spotlight

Read MoreHide Full Article

The fragile ceasefire in Gaza, which took effect on Oct. 10, 2025, faced its most serious test over the past weekend, as a resurgence of violence put the conflict back in the global spotlight. This has naturally intensified investor focus on defense stocks and related exchange-traded funds (ETFs).

This is because geopolitical instability, like the conflict in Gaza, which poses a threat to regional peace, tends to enhance the business prospects of defense contractors as governments increase military spending. The recent escalation serves as a stark reminder of this dynamic, casting a direct spotlight on companies involved in producing the weapons and technologies that power modern warfare.

More Than Just a Conflict: Broader Tailwinds for Defense

Companies that supply military hardware to Israel, particularly U.S.-based firms, see their order books and stock prices potentially boosted by sustained conflict or a perceived need to replenish stockpiles. Major defense contractors, including Lockheed Martin ((LMT - Free Report) ), the supplier of F-35 fighter jets; Boeing ((BA - Free Report) ), which provides F-15 fighter jets; and RTX Corp. ((RTX - Free Report) ), a key participant in the Iron Dome system, have been cited as playing a significant role in supplying arms and components to Israel.

This direct involvement makes them particularly sensitive to the conflict’s duration and intensity. No doubt, the 1.8%, 2.2% and 1.8% hike observed in the share price of RTX, LMT and BA, respectively, in the last trading session was largely driven by the latest ceasefire violation by Israel.

While the situation in Gaza is a significant driver, the defense ETFs are also being fueled by a confluence of powerful, longer-term factors like resilient demand, technological innovation and surging defense budgets.

Defense spending is mostly considered non-cyclical. Governments maintain defense budgets regardless of the economic climate, providing defense contractors with predictable revenue streams. This offers a degree of stability that is attractive to investors, especially during times of broader market volatility.

The defense sector is experiencing a revolution driven by artificial intelligence (AI), autonomous drones, and cyber warfare. These technologies are transforming modern warfare and driving defense department spending, creating significant growth opportunities for companies at the forefront of innovation.

Governments worldwide are significantly increasing military spending. In the United States, the recently enacted "One Big Beautiful Bill Act" (OBBB) injected an additional $150 billion in new funding for national security and defense priorities on top of the already substantial annual defense budget.

On the other hand, in June 2025, the North Atlantic Treaty Organization (“NATO”) members agreed to a new target to spend 5% of their GDP on defense and security by 2035, marking a significant increase from the previous benchmark of 2%, which was set in 2014. With America being the largest weapon supplier in the world, this enhanced NATO spending should fuel U.S.-based defense manufacturers manifold.

This powerful combination of persistent geopolitical tensions, expanding government budgets, and transformative innovation has positioned the defense sector for sustained growth, making defense ETFs a strategic consideration for portfolios. The Gaza narrative has only intensified this growth prospect.
