Ongoing US Iran War, Energy Surge

Ongoing tensions in the Middle East are expected to remain a key focus for global financial markets in the near future, as investors closely monitor developments in Iran and the broader impact of rising energy prices.

With the U.S.-Israel conflict involving Iran now entering its third week, oil prices have surged by more than 40%, raising concerns about increasing inflation and slowing economic growth worldwide.

These inflation worries have already influenced market expectations, with investors scaling back hopes for interest rate cuts this year that were previously seen as supportive for equities.

At the latest Federal Reserve meeting, Chair Jerome Powell acknowledged significant uncertainty about how the situation might affect the economy, making it more difficult for policymakers to predict future conditions.

Meanwhile, the benchmark S&P 500 index is on track for its fourth consecutive weekly loss. Geopolitical tensions intensified further this week after Iran launched attacks on energy infrastructure across the region in response to Israel targeting its gas facilities.

Market experts highlight the unpredictability of the situation. According to Chris Fasciano, chief market strategist at Commonwealth Financial Network, the conflict could either ease quickly or persist for an extended period, with longer durations likely increasing the risk of economic impact in the United States.

Fluctuations in oil prices have had a broad impact across financial markets. U.S. crude briefly touched $100 per barrel, while Brent crude hovered around $110.

The disruption has been worsened by reduced activity in the Strait of Hormuz, a critical route that typically handles about 20% of the world’s oil and liquefied natural gas shipments.

Data indicates a strong inverse relationship between oil prices and equities, with the S&P 500 and U.S. crude moving in opposite directions in recent weeks.

Investment professionals emphasize the importance of tracking oil prices as a leading signal for market sentiment. According to Eric Kuby, chief investment officer at North Star Investment Management, crude price movements often reflect how markets perceive the trajectory of the conflict.

While energy stocks within the S&P 500 have benefited from rising oil prices, the sector represents less than 4% of the overall index, limiting its ability to offset broader market declines.

As of now, the S&P 500 has fallen by just over 5% from its record high reached in late January.

Unlike previous sharp market drops—such as the sudden decline following tariff announcements last April—recent losses have been more gradual and controlled. Analysts suggest this may reflect strong underlying fundamentals within corporate America, which continue to provide some support to the market.

However, rising Treasury yields are emerging as another concern. Driven by higher energy prices and cautious signals from central banks, the benchmark 10-year U.S. Treasury yield recently climbed to 4.328%, its highest level since August, before easing slightly.

Keith Lerner, chief investment officer at Truist Advisory Services, noted that a sustained rise above 4.3% could place additional pressure on equities. Higher yields increase borrowing costs and may slow economic activity, while also making bonds more attractive relative to stocks.

From a technical perspective, the market is approaching critical levels. The S&P 500 recently closed below its 200-day moving average for the first time since May, a signal closely watched by analysts.

According to Adam Turnquist, chief technical strategist at LPL Financial, a further decline below key support levels could raise concerns about the durability of the current bull market.

Looking ahead, the upcoming week features a relatively light economic calendar, with reports on manufacturing, services, and consumer sentiment expected. However, a major energy conference in Houston involving top industry leaders may draw additional market attention.

Despite these events, developments in Iran are likely to remain the dominant driver of market sentiment. Analysts at UBS Global Wealth Management noted that recent developments are increasing the likelihood of prolonged conflict, greater infrastructure damage, and sustained high oil prices.

While there is still a possibility of a less severe outcome—particularly regarding disruptions in the Strait of Hormuz—the window for such a scenario appears to be narrowing, leaving markets vulnerable to continued volatility.
