As the conflict in Iran continues, US defence stocks have experienced a notable decline, suggesting that the initial enthusiasm for military expenditure has begun to wane. The NYSE Arca Defence Index, which tracks a diverse array of US defence firms, fell by nearly 8% in March, contrasting with the broader S&P 500’s dip of 5%. This downturn follows a strong performance earlier in the year, indicative of a recalibration among investors in response to evolving geopolitical tensions.
Decline Amidst Conflict
Historically, financial markets often react positively to conflicts, with defence stocks typically experiencing a surge in value. However, strategists note that the recent downturn signals a shift. In February, prior to the escalation of hostilities, defence shares had risen approximately 12%, driven in part by expectations of increased military spending. David Bianco, the Americas Chief Investment Officer at DWS, explained that the prior valuations had incorporated a significant “conflict premium,” which now appears to be unwinding.
Bianco had anticipated this shift and began reducing his holdings in defence stocks before the situation in the Middle East intensified. He commented, “A lot of conflict premium was in their valuations. We saw gold and oil and defence rally, part of the reason was messages from the administration when Trump was sending the armada to the Middle East. Nobody knew anything, but they saw chances of a conflict.”
Broader Market Implications
The downturn in US defence equities mirrors trends seen in the European market, which reported an 11% drop in defence stocks—the largest monthly decline since the pandemic. This is primarily attributed to fears of an energy crisis stemming from the ongoing war. European governments had previously announced significant rearmament initiatives in response to Russia’s actions in Ukraine, fuelling optimism in the sector.
Despite President Trump’s ambitious proposal for a US$1.5 trillion military budget by 2027, analysts remain sceptical about the passage of such a substantial increase through Congress. Bernstein analyst Douglas Harned noted that current developments do not suggest that the proposed budget could be exceeded, indicating a lack of immediate upside from the ongoing conflict.
Earnings Growth and Production Challenges
Investor expectations regarding earnings within the defence sector have also diminished. Analysts reported that, by the end of March, growth projections for major companies like General Dynamics and Lockheed Martin stood at around 12%, a decrease from 15% earlier in the year. Sameer Samana from Wells Fargo Investment Institute highlighted that for earnings estimates to rise significantly, the conflict would need to persist or expand substantially.
The Pentagon’s efforts to ramp up production to replenish depleted stockpiles have not yet translated into immediate revenue gains. Analysts emphasise that prolonged production cycles and existing capacity constraints will delay any potential financial benefits. Richard Safran, a senior analyst at Seaport Research Partners, added that during conflicts, funding for defence firms tends to be redirected towards immediate operational needs, rather than long-term modernisation or development projects.
Policy Pressure and Future Outlook
Additionally, the Trump administration is exerting pressure on defence contractors to prioritise production over shareholder returns, further complicating the financial landscape for these firms. As a result, the medium-term outlook for the defence sector hinges significantly on forthcoming US budget decisions, with vital spending details expected to be revealed on April 21.
Why it Matters
The shifting dynamics in the defence stock market reflect broader concerns about the sustainability of military spending amid fluctuating geopolitical tensions. As investors reassess valuations and corporate strategies in light of production limitations and potential budget constraints, the future of the defence sector remains uncertain. This situation underscores the intricate relationship between political decisions, market behaviour, and the implications for national security and economic stability.
