The ongoing escalation of conflict between the US and Iran, coupled with disruptions to shipping through the Strait of Hormuz, has driven international oil prices to around $97 per barrel. Against this backdrop of heightened geopolitical risk, the energy sector has become a central focus for the market, with investors actively searching for opportunities that offer both a margin of safety and long-term value.

Supply Landscape Reshaped by Strait Closure

Since US and Israeli strikes on Iran in late February, the Strait of Hormuz has been effectively closed. The timeline for reopening this critical maritime chokepoint, which handles about 20% of global oil supply, remains highly uncertain. Although a ceasefire agreement was reached in April, repeated violations by both sides have led Iran to formally suspend ceasefire talks. This signals that the global energy market is facing its largest supply disruption in decades.

The US Energy Information Administration forecasts that global oil inventories will shrink by an average of 8.5 million barrels per day in the second quarter, potentially falling to critically low levels ahead of the peak demand season. Market concerns over tight supply have intensified following warnings from the International Energy Agency.

Contrasting Profiles Among Major Oil Giants

In the face of this structural supply shock, the three major US oil supermajors, with their secure production profiles and robust cash flows, have become a preferred destination for safe-haven capital.

Chevron delivered a better-than-expected first quarter, with earnings per share of $1.41 significantly surpassing the market consensus of $0.97. Its dividend yield of 3.78% leads among the three giants. Management's reaffirmation of a production growth target of 7% to 10% by 2026 makes it a top pick in the current environment.

ExxonMobil, leveraging its scale, generated $2.7 billion in free cash flow in Q1 and leads the industry in shareholder returns. However, its dividend yield has compressed to 2.7%, the lowest level since 2014, reflecting that the stock price has already priced in some of the geopolitical premium.

ConocoPhillips stands out for its capital discipline, generating $2.4 billion in free cash flow last quarter. Its 2.74% dividend yield is mid-range, but the company lacks near-term catalysts for production growth.

Petrobras: A Mix of Opportunity and Risk

Petroleo Brasileiro SA Petrobras (PBR) also benefits from rising oil prices. As a net oil exporter, its share price has surged following the geopolitical conflict. Analysts note that if the Strait of Hormuz remains closed long-term, Asian refineries will seek alternative supplies, potentially allowing Brazilian crude to command a premium.

However, the pressure on domestic fuel price transmission in Brazil cannot be ignored. The country relies on imports for about a quarter of its diesel supply. Disruptions to Middle Eastern supplies could push up import costs, exacerbating inflationary pressures and creating a pricing dilemma for the company.

Overall, in an environment of persistent geopolitical risk and structurally tightening supply, energy giants with secure production, strong cash flows, and sustainable dividends hold investment value. Investors should focus on underlying fundamentals rather than the short-term volatility driven by news flow.
