Oil Tanker Attack in Strait of Hormuz Impacts Global Oil Supply

What happened

Four oil tankers, including a 'supertanker' carrying more than two million barrels of oil, have hit mines and caught fire while travelling through the Strait of Hormuz. The incident occurs in a context where Tehran has asserted control over much of the waterway since the US and Israel launched the war on February 28.

Why it matters

The Strait of Hormuz is a crucial maritime route for global oil transportation, through which a significant portion of the world's supply passes. An attack on oil tankers in this region, especially a supertanker with such a voluminous cargo, represents a direct disruption to oil supply. The loss of two million barrels of oil is substantial and can unbalance the market, which is already operating under the influence of geopolitical tensions. Tehran's assertion of control over the waterway adds a layer of geopolitical risk, suggesting that such incidents may not be isolated and could escalate, affecting the security of oil transport in the long term.

Market impact

• Interest rates and bonds: In a scenario of increased geopolitical uncertainty and potential oil-driven inflation, investors tend to seek out assets considered safer. This could lead to a drop in short-term Treasury yields as demand for safety increases. However, the prospect of higher inflation could push long-term yields upwards, reflecting the expectation that central banks may need to maintain a more restrictive stance.
• Dollar and exchange rates: The dollar tends to strengthen in times of global risk aversion, acting as a safe haven. Emerging market currencies, such as the real, tend to depreciate against the dollar due to capital flight and the perception of higher risk. Higher oil prices can also be a negative factor for oil-importing countries, impacting their trade balances and currencies.
• Equities: Global equity markets tend to react negatively to oil supply shocks and escalating geopolitical tensions. Energy-dependent sectors, such as aviation and transportation, may be particularly affected by rising fuel costs. Energy companies, on the other hand, may see their shares appreciate due to higher oil prices, but overall market sentiment tends to be cautious and bearish.
• Commodities: Oil is the most directly impacted commodity. Oil prices (Brent and WTI) tend to rise sharply due to reduced supply and the geopolitical risk premium. Other commodities may have mixed reactions, but energy inflation can have a ripple effect on production and transportation costs.
• Brazil: Brazil, as an oil producer and exporter, may see an initial benefit to its trade balance and for companies in the sector. However, higher oil prices also pressure domestic inflation, which could lead the Central Bank (Copom) to maintain the Selic at higher levels for longer or even consider monetary tightening, negatively impacting economic growth and the local interest rate market.

What to watch

Tehran's next steps and the international response to the incident will be crucial. Any military escalation or more aggressive rhetoric could intensify the perception of risk. Furthermore, assessing the extent of the damage and the time needed to restore transport capacity in the region will be important for calibrating the impact on oil supply. Statements from major oil producers regarding their ability to offset the supply loss should also be monitored.

Scenarios

Base Case: Oil prices remain elevated in the short term, with a persistent geopolitical risk premium. Global inflation is impacted, leading central banks to maintain more cautious monetary policies. Global equity markets operate under pressure. Risk Scenario: A military escalation in the region leads to more severe disruptions in the Strait of Hormuz, causing an even larger oil supply shock and a global energy-driven recession. Risk aversion reaches extreme levels, with a strong flight to safe-haven assets.
