Iran Conflict Roils Markets, Forcing a 30% Rotation to Energy

The US-Iran conflict that began on February 28 has upended investment strategies, with fund managers now scrambling to re-price risk as Brent crude hovers near $107 a barrel.

Escating geopolitical tensions in the Middle East following the US-Iran conflict have triggered a significant rotation in equity markets, forcing investors to abandon growth-oriented technology names and seek refuge in energy and materials stocks to hedge against sustained high oil prices and persistent inflation.

"The first quarter of 2026 was defined by a meaningful shift in market leadership and risk perception, driven primarily by escalating geopolitical tensions in the Middle East," Nathan Fredrick, a portfolio manager at Riverwater Partners, wrote in a recent client note. "The outbreak of conflict involving Iran introduced a significant exogenous shock, most visibly through higher energy prices and increased volatility across global markets."

The shift was stark. Brent crude prices surged, hovering near $107 a barrel and driving the energy holdings of some small-cap funds up nearly 30 percent in the first quarter. In contrast, technology and financial stocks faced headwinds, with some fintech-exposed names like Coastal Financial (CCB) falling over 6 percent as investors questioned the durability of their business models amid tightening credit.

The conflict is forcing a broader strategic reassessment beyond immediate market moves, exposing the fragility of global supply chains and energy-dependent economies. For an economy like Taiwan, which imports 97 percent of its energy, the crisis serves as a real-time stress test, while for China, it offers an invaluable playbook on exploiting such vulnerabilities, according to analysis from Brahma Chellaney at the Center for Policy Research.

From Growth Narratives to Commodity Hedges

The market's rotation in the first quarter was swift and decisive. Sectors that previously led the market, particularly software and AI-linked businesses, saw valuations compress as concerns emerged around their long-term growth prospects in a high-inflation environment. In their place, long-neglected sectors like energy, materials, and industrials have taken leadership. Riverwater Partners, a small-cap investment firm, noted its energy holdings returned nearly 30 percent on average during the quarter.

The firm's top individual performer was Modine Manufacturing (MOD), a thermal management company benefiting from data center demand, which saw its stock appreciate over 60 percent. Conversely, the firm's largest detractors included financial company Coastal Financial (CCB) and medical device maker AtriCure (ATRC), which suffered from a shift in investor sentiment despite strong underlying business performance. "We have begun repositioning the portfolio toward areas that are better aligned with the current environment," Riverwater's commentary stated. "We see increasing opportunity in energy and materials, which we believe stand to benefit from supply disruptions and sustained higher commodity prices."

A Geopolitical Stress Test With Global Reach

The conflict's impact extends far beyond a simple sector rotation, acting as a stress test for the global economy. The standoff has kept crude prices elevated, with instability around the Strait of Hormuz—a chokepoint for 21 percent of global oil trade—reinforcing inflation concerns. "For India, this remains the single most critical macro variable, as elevated oil prices not only pressure inflation and the rupee but also weigh on corporate profitability across sectors," said Hariprasad K, founder of Livelong Wealth.

The crisis has also laid bare the vulnerabilities of energy-dependent economies. Taiwan, which imports 97 percent of its energy and maintains only 11 days of liquefied natural gas reserves, faces existential questions about its economic model. According to Brahma Chellaney, a professor of strategic studies, the conflict serves as a "live laboratory" for Beijing, providing invaluable data on how to exploit Taiwan's economic and energy fragilities in a future crisis. The diversion of US military and political attention to the Middle East further complicates the strategic calculus for allies in the Indo-Pacific.
