Iran’s New Leader Vows Strikes on US, Closure of Hormuz Strait | Oil Prices Surge

The newly appointed Supreme Leader of Iran, Mujtaba Khamenei, has vowed to maintain attacks on US military bases in the region and to keep the Strait of Hormuz closed, escalating tensions following the recent assassination of his father, Ali Khamenei. This declaration, delivered in his first public message since assuming office, signals a continuation of Iran’s assertive foreign policy and raises concerns about further disruption to global energy markets and regional stability.

A Succession Forged in Conflict

Mujtaba Khamenei’s ascent to the highest office in Iran occurred after his father, Ali Khamenei, was killed in US and Israeli strikes on Tehran on February 28th. The appointment, ratified by the Assembly of Experts, was announced simultaneously to the public and to the new leader himself, a detail Khamenei noted in his televised address. This unusual circumstance underscores the urgency and internal dynamics surrounding the succession. The timing of the strikes and the subsequent rapid appointment of his son have fueled speculation about a pre-planned transition, though this remains unconfirmed. Khamenei’s initial statement, broadcast on Iranian state television without a visual appearance, focused heavily on retribution and the defense of Iranian interests.

Targets and Threats: US Bases and the Strait of Hormuz

Khamenei’s message contained explicit threats against US military installations in the region. He called for the “disruption” of these bases, alleging they are used to harm Iranians. He specifically stated that attacks would continue as long as the “American-Israeli war” against Iran persists, though he left open the possibility of a policy shift based on evolving “interests.” Perhaps more immediately impactful is his commitment to maintaining the closure of the Strait of Hormuz, a critical waterway for global oil supplies. The Strait, which handled 20 million barrels per day of crude and products last year, has seen flows collapse by over 90% since the conflict began, according to reports. This closure has already sent shockwaves through the energy market, pushing Brent crude above $100 per barrel. The International Energy Agency (IEA) has described the situation as the “largest disruption in history” to the global oil market, estimating a reduction of 8 million barrels per day in global supplies this month.

Regional Alliances and Accusations

Whereas advocating for strong relations with neighboring countries, Khamenei accused “the enemy” of establishing military and financial bases within those nations to exert regional dominance. He claimed these bases were used in the recent aggression against Iran and urged those countries to close them “as soon as possible,” dismissing US security assurances as “lies.” He specifically thanked Lebanon’s Hezbollah and the “resistance front in Iraq” for their support, labeling them “our best friends” and suggesting they would accelerate the effort to eliminate what he termed the “Zionist entity.” This rhetoric highlights Iran’s reliance on non-state actors to project power and influence in the region. Khamenei also vowed to seek compensation for war damages, threatening to seize or destroy equivalent assets if the “enemy” refuses to pay.

The Economic Fallout and International Response

The conflict’s impact extends far beyond the immediate region. The IEA reports that the war has affected approximately 7.5% of global oil supplies. To mitigate the market impact, IEA member states have agreed to release an unprecedented 400 million barrels from emergency reserves. Yet, high prices, flight cancellations, and economic uncertainty have also slowed global consumption growth to its lowest level since April of last year, at 640,000 barrels per day. Saudi Arabia and the United Arab Emirates have attempted to utilize alternative export routes, but the effective closure of the Strait of Hormuz has forced regional producers to curtail a combined 10 million barrels per day of production. The situation underscores the vulnerability of global energy supply chains to geopolitical instability.

What’s Confirmed and What Remains Unclear

Confirmed: Mujtaba Khamenei has succeeded his father as Supreme Leader of Iran following Ali Khamenei’s assassination. He has publicly vowed to continue attacks on US bases and maintain the closure of the Strait of Hormuz. The conflict has caused significant disruption to global oil markets, prompting an emergency release of reserves. Iran has launched missile and drone attacks across the Gulf region. Unclear: The extent to which Khamenei’s threats will be carried out, the long-term impact of the Strait of Hormuz closure, and the potential for escalation involving other regional actors. The precise details of Ali Khamenei’s assassination, including the level of US and Israeli involvement, remain contested. The internal dynamics within the Iranian leadership following the succession are also largely opaque.

The Assembly of Experts and Iran’s Political Structure

The Assembly of Experts, the body responsible for selecting the Supreme Leader, is comprised of 88 clerics elected to eight-year terms. While theoretically accountable to the public, the vetting process ensures that only candidates deemed loyal to the Islamic Republic are permitted to run. The Assembly’s decision to swiftly appoint Mujtaba Khamenei, despite his relatively limited public profile prior to his father’s death, suggests a desire for continuity and stability within the regime. The choice of Khamenei, as noted by the Los Angeles Times, reflects Iran’s defiance and makes a regime change unlikely in the near term. This structure, designed to ensure the continuation of the Islamic Republic’s ideology, presents a significant challenge to any external efforts to influence Iran’s policies.

Looking Ahead: Diplomatic Pathways and Potential Escalation

The immediate future hinges on several factors. The response of the United States and Israel to Khamenei’s threats will be crucial. Further military strikes could trigger a wider regional conflict. Diplomatic efforts, potentially mediated by countries like Oman or Qatar, may be necessary to de-escalate tensions and reopen communication channels. However, given the deep-seated mistrust and conflicting interests, the prospects for a swift resolution appear limited. The ongoing negotiations surrounding Iran’s nuclear program, already stalled, are likely to be further complicated by the current crisis. The international community faces a delicate balancing act: maintaining pressure on Iran to curb its destabilizing activities while avoiding actions that could escalate the conflict and further disrupt global energy markets. The situation demands careful calibration and a sustained commitment to diplomatic engagement, however challenging that may be.

The coming weeks will likely notice continued monitoring of the Strait of Hormuz for any signs of easing or further tightening of the blockade. Regional actors will be closely watched for any shifts in their positions or increased military activity. The IEA will continue to assess the impact of the conflict on global oil supplies and coordinate potential responses with member states. The path forward will depend on the choices made by the key players involved and their willingness to prioritize de-escalation and dialogue.
