Background on Key Players and Relevance

Donald Trump, the President of the United States, announced on Monday afternoon that Iran and Israel had reached an agreement to cease their mutual attacks, effectively ending a 12-day conflict. This development led to significant repercussions in the global oil market.

Immediate Market Reactions

At the start of Asian trading on Monday, oil prices dropped following Trump’s announcement about an impending ceasefire between Iran and Israel. The decline was substantial, with international crude oil prices falling more than $5.

Specific Price Movements

  • Brent crude futures dropped $5.53, or 7.18%, to $71.48 per barrel – marking its worst fall since August 1, 2022, when it declined by 9.07%.
  • West Texas Intermediate (WTI) crude fell $5.53, or 7.22%, to $68.51 per barrel, recording its largest decline since July 12, 2022, when it dropped by 7.93%.
  • Mexico’s export crude mix closed at $65.37, a 7.16% or $5 decrease.

In early Asian trading, both WTI and Brent continued to fall, with WTI down 2.6% and Brent dropping 3.7%, accumulating a 9.8% decline for WTI and a 10.8% drop for Brent.

Geopolitical Context and Implications

China’s rejection of Iran’s intention to block the Strait of Ormuz played a crucial role in the oil price decline. The strait is vital for oil transportation, with 20 million barrels passing through daily. It connects the Persian Gulf to other destinations, carrying 20% of the world’s oil trade. Any disruption would severely impact global oil commerce, posing a significant risk.

Ole Hansen from Saxo Bank stated, “All eyes are on the Strait of Ormuz and whether Iran will attempt to disrupt shipping.” Even a threat of interference could delay shipments through the strait, causing prices to rise.

According to the International Energy Agency, 20% of global oil production passes through this region. A sustained closure would economically harm Iran, making any blockade a double-edged sword, as noted by Sugandha Sachdeva from SS WealthStreet.

Felipe Mendoza, an analyst at ATFX LATAM, commented on the current market environment: “The current market mood is shaped by a volatile mix of geopolitical tensions, uncertain monetary policy decisions, and mixed economic cycle signs.” He added that if tensions in the Middle East remain at their current level by mid-year, there could be a favorable environment for risk assets. However, uncertainty still looms, and “the movements of the S&P 500 and Brent crude will serve as key indicators of the balance between growth narrative and geostrategic risk.”

Impact on Oil Company Stocks

Following the attacks on a US military base, shares of oil companies listed on stock exchanges fell. ConocoPhillips, a US-based oil exploration and production company, experienced the largest drop of 3.15% to $91.71 per share.

  • Petrobras, a Brazilian energy company, saw a 2.85% decline to 34.90 Brazilian real.
  • Exxon Mobil, another US-based company, fell 2.58% to $111.74 per share.
  • Chevron and Enterprise Products Partners L.P., both US oil companies, also reported stock declines of 1.8% and 1%, respectively.
