Iran Warns of 'Unimaginable' Response Amid Rising Tensions in Strait of Hormuz

What happened

Iran has warned the United States that any new act of militarism would lead to an 'unimaginable' response. Iranian parliament speaker Mohammad Baqer Qalibaf stated that Iran would not back down from military threats and would defend its territorial integrity. This declaration comes a day after US President Donald Trump suggested the possibility of striking Iran or reaching a 'big, beautiful' agreement. Tensions are exacerbated by the dispute over the future of the Strait of Hormuz, a crucial maritime route. On the same day, the Iranian army announced it had shot down a US LUCAS drone near the port city of Bandar Abbas, close to the strait.

Iranian Foreign Minister Abbas Araghchi stated that the security situation in the region has completely changed following the conflict with the US and Israel, and that the management of the Strait of Hormuz would not return to its previous state. He emphasized that new realities have emerged and that shipping routes through the strait will be managed differently. Araghchi also indicated that Tehran would welcome security arrangements developed by countries in the region rather than those imposed by outside powers. Although an interim deal was signed in June to resolve the conflict, diplomatic negotiations have since stalled amid renewed tensions.

Why it matters

The Strait of Hormuz is one of the most important maritime routes in the world, connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. Its security is vital for international energy shipments, as a significant portion of global oil passes through it. Iranian threats and US rhetoric raise the risk of disruptions to oil flow, which could have significant implications for commodity prices and the global economy. Iran's stance of not backing down and seeking new management for the strait signals a potential escalation in the region, with far-reaching geopolitical and economic repercussions. Uncertainty over navigation and security in the strait could impact investor confidence and market stability.

Market impact

• Interest rates and bonds: Escalating geopolitical tensions tend to increase demand for safe-haven assets, such as US Treasuries. This could lead to a decrease in yields on sovereign debt of developed economies as investors seek protection against uncertainty. However, if the conflict worsens and impacts global growth, there could be inflationary pressure via energy prices, which could, at a later stage, lead to an increase in long-term yields.
• Dollar and exchange rates: The US dollar tends to strengthen during periods of global risk aversion, acting as a safe haven. Emerging market currencies, such as the Brazilian real, may depreciate against the dollar due to capital flight to safer assets and the perception of increased global risk.
• Equities: Global stock markets tend to react negatively to geopolitical tensions, especially those that threaten energy supply or economic stability. Sectors most sensitive to global growth and oil prices may be particularly affected. The Ibovespa, for example, may suffer from risk aversion and the depreciation of the real, although commodity exporting companies might see some marginal benefit if commodity prices rise.
• Commodities: Oil is the most directly impacted commodity. The threat of disruption in the Strait of Hormuz, through which a large portion of the world's oil passes, tends to drive up crude prices. Other energy commodities may also be affected, and uncertainty can generate volatility in precious metals markets, which also function as safe-haven assets.
• Brazil: Brazil, as an oil importer and with an economy sensitive to external shocks, may face inflationary pressure due to rising oil prices and the depreciation of the real. This could complicate the Central Bank's monetary policy, potentially limiting room for Selic rate cuts or even requiring a more cautious stance.

What to watch

Investors should closely monitor diplomatic developments between the US and Iran, as well as any military movements in the Persian Gulf region. Statements from officials on both sides, reports on navigation security in the Strait of Hormuz, and data on global oil inventories will be crucial. Additionally, the reaction of other countries with interests in the region, such as Saudi Arabia and other OPEC members, could influence the scenario.

Scenarios

Base Scenario: Tensions remain elevated but without direct and sustained military escalation. Oil prices remain volatile but without a surge, and the dollar strengthens moderately. Diplomatic negotiations may resume, albeit intermittently. Risk Scenario: A significant military escalation in the region, with disruptions in the Strait of Hormuz. This would lead to an oil price shock, strong global risk aversion, sharp dollar appreciation, and a widespread decline in stock markets, with global inflationary and recessionary impacts.
