Increased Ship Attacks in Hormuz Strait Elevate Geopolitical Risk for Oil

What happened

Iran has intensified attacks on ships in the Strait of Hormuz, one of the world's most critical maritime routes for oil transport. This escalation occurs at a time when oil flows through the region are high, increasing the vulnerability of the global supply chain.

Why it matters

The Strait of Hormuz is a strategic chokepoint through which a significant portion of the world's oil passes. Any disruption or threat to navigation in this area has the potential to directly impact global oil supply, generating uncertainty and volatility in energy markets. The intensification of attacks raises geopolitical risk in the Middle East region, which could have broader repercussions for the global economy, given concerns about inflation and economic growth.

Market impact

• Interest rates and bonds: Increased geopolitical risk and potential higher oil prices could fuel inflationary pressures. This tends to lead central banks, such as the Fed, to price in higher interest rates to curb inflation. Consequently, yields on Treasuries and other sovereign bonds may rise, reflecting expectations of tighter monetary policies and increased risk aversion.
• Dollar and exchange rates: In times of heightened global uncertainty and risk aversion, the US dollar tends to strengthen, acting as a safe haven. Emerging market currencies, including the Brazilian real, may depreciate against the dollar, especially if rising oil prices negatively impact trade balances or generate domestic inflationary pressures.
• Equities: Elevated geopolitical risk and the possibility of higher energy prices tend to be negative for global stock markets. Companies with high energy costs or exposure to global supply chains may suffer, while increased uncertainty can lead investors to reduce exposure to risk assets. Energy sectors, however, may benefit from higher oil prices.
• Commodities: Oil is the most directly affected commodity. Expectations of supply disruptions or an increase in the geopolitical risk premium tend to push oil prices (Brent and WTI) higher. Other commodities, especially those linked to energy or sensitive to global growth, may also be impacted.
• Brazil: Brazil, as an oil producer, may see an initial benefit in export revenue from higher oil prices. However, the appreciation of the dollar and increased domestic inflation (due to fuel and other product imports) could pressure the Copom's monetary policy, potentially leading to a higher Selic rate for longer. The Ibovespa may feel the negative impact of the global risk-off scenario, although listed oil companies might perform relatively better.

What to watch

Next steps to monitor include the frequency and intensity of attacks in the Strait of Hormuz, the reactions of global and regional powers, and any official communication regarding navigation safety. Furthermore, the evolution of oil inventories and global demand will be crucial for assessing the lasting impact on prices.

Scenarios

Base scenario: Attacks continue sporadically, maintaining a risk premium on oil but without significant disruptions to flows. Markets remain cautious, with oil at elevated levels. Risk scenario: A major escalation of attacks or a severe incident resulting in prolonged disruption of oil transport through the Strait of Hormuz. This would lead to a supply shock, a surge in oil prices, strong global risk aversion, and sharp inflationary pressure.
