US defense stocks failed to benefit from the Iran conflict, indicating that the current global market's approach to pricing geopolitical conflict has changed. In the past, wars typically benefited the defense sector directly, as investors would quickly map "increased military spending" and "growth in orders" to profit expectations. However, this time, the market is more concerned with high oil prices, fiscal uncertainty, and profit realization cycles, meaning that energy, rather than traditional defense sectors, truly benefits. The weakening of defense stocks essentially reflects a shift from "conflict trading" to "stagflation trading."
Why the Market Bought Oil First, Then Sold Defense Stocks
The reason is that the Iran conflict initially impacts energy and shipping rather than defense profits. Reuters reported on April 2 that Trump's tougher stance led to a Wall Street downturn, Brent oil prices climbed above $108, and the VIX rose, with energy stocks relatively stronger. This cross-asset performance shows the market is most concerned about high oil prices driving inflation and suppressing growth, rather than an immediate profit surge for defense companies. While the defense sector theoretically benefits from inventory and capacity expansion, these gains realize more slowly; the energy sector benefits immediately from commodity price increases. Therefore, when funds are limited and macro uncertainty is high, the market prioritizes buying the most direct beneficiaries.
Long-term Logic in Defense Stocks Remains, but Short-term Anchors Have Changed
Defense stocks do have a long-term logic. Trump's proposed $1.5 trillion defense budget for the 2027 fiscal year, the Pentagon's expansion agreements with contractors, and rising demand for missiles and air defense systems all indicate that the industry's medium-term prosperity has not disappeared. However, capital markets price based on marginal changes. If these factors were heavily traded by the market in January and February, by April, investors would no longer inflate prices based on the same logic. Instead, they would ask: Can the budget pass? When will profits be realized? Will expansion first consume cash flow? This is why Reuters interpreted the March sector pullback as position closing and valuation digestion, not demand contraction.
Cross-Asset Implications
This situation has three implications for cross-asset markets. First, it shows that war does not automatically lead to an increase in defense stocks; asset pricing relies more on the speed of transmission and starting valuations. Second, it reminds investors that high oil prices and geopolitical conflicts may primarily benefit energy, gold, and the US dollar, rather than all "war beneficiaries." Third, it reflects that in the context of fiscal deficits, high interest rates, and limited capital returns, even if defense spending trends upward in the long term, related stocks may still go through a phase where "orders look good, but stock prices don’t rise." This judgment is based on the sector performance, valuation data, and budget uncertainty summarized in Reuters' report.
A Longer-Term Market Narrative
In the longer term, the fact that US defense stocks didn't benefit from this war may indicate that the sector is transitioning from being "theme-driven" to "execution-driven." In recent years, geopolitical conflicts, ally military expansions, and shifts in US policy have helped the industry achieve valuation reappraisals. In the coming years, the market may place more emphasis on specific capacity building, budget implementation, order structure, and profit conversion efficiency. In other words, defense stocks have not lost strategic significance; the market is just no longer willing to increase valuations based solely on conflict headlines. If late-April budget details are strong and subsequent earnings are revised upward, the sector may still gain support; if the budget is blocked and capital expenditures continue to squeeze shareholder returns, high valuations themselves will become an obstacle.
