A joint military strike by the United States and Israel over the weekend, described as the largest and most forceful to date, directly resulted in the death of Iran's long-ruling Supreme Leader, Ayatollah Ali Khamenei. This action has pushed the Middle East to the brink of a wider conflict. Iran subsequently launched retaliatory airstrikes targeting multiple countries across the region, drawing significant international attention. Financial markets swiftly entered a state of high alert following the event, with investors closely monitoring developments and preparing for potential sharp volatility. Current information indicates the conflict poses a major threat to energy supplies, the geopolitical landscape, and global economic stability.
The death of Supreme Leader Khamenei marks a seismic event for the Middle East. Iranian state media officially announced on Sunday that Khamenei was killed in the joint U.S.-Israel strike. The news spread rapidly worldwide, seen as one of the most disruptive events for Iran since the 1979 Islamic Revolution. Khamenei, who had led Iran since 1989 and held ultimate decision-making power, leaves behind a power vacuum that could trigger internal power struggles and instability.
The U.S. President characterized the operation as the boldest foreign policy move of his tenure, particularly with mid-term elections approaching in November. He publicly stated the strike offered "the single greatest opportunity for the people of Iran to take back control of their country." In a post on Truth Social, the President issued a stern warning, emphasizing that "heavy and precise bombing will continue, non-stop all week, or longer as needed, until the goal of lasting peace throughout the Middle East and indeed the world is achieved." He had stated on Saturday that the core objective of the military action was to completely eliminate the long-standing threat posed by Iran to the region and the U.S., specifically to prevent it from developing nuclear capabilities.
In response to the strike, Iran swiftly launched an unprecedented retaliatory campaign, with missile and drone attacks targeting U.S. military bases in neighboring countries and Israel itself. Air raid sirens and emergency mobile alerts were activated across Israel, sending large numbers of citizens rushing to shelters. While Israeli defense systems, including the Iron Dome, successfully intercepted most of the volleys of missiles launched by Iran, the attacks still caused localized panic and casualties.
The scope of the attacks widened further, with explosions reported in the United Arab Emirates, Jordan, Qatar, Bahrain, and Saudi Arabia. Video footage showed smoke billowing inside concourses of Dubai International Airport as people fled in panic. Drone strikes directly caused damage to infrastructure and casualties at both Dubai International Airport and Abu Dhabi's Zayed International Airport. Iran's Foreign Ministry had stated on Saturday that it would not "hesitate in the face of U.S.-led aggression." A spokesperson for Iran's armed forces issued a严厉警告, stating that Israel and the U.S. would "receive a painful lesson unlike any in their history." The U.S. President responded on Truth Social on Sunday, warning that if Iran continued its retaliation, the U.S. would respond with "unprecedented force."
As the conflict escalated, global investors shifted decisively into risk-off mode, anticipating pronounced safe-haven trading when markets reopen. Traditional safe-haven assets like the U.S. dollar and gold are expected to strengthen significantly, while stock markets face downward pressure. On the 24-hour trading crypto platform Hyperliquid, oil-related perpetual swap futures had already risen nearly 5% to $71.7 per barrel; gold futures also climbed about 1.2% to $5,334 per troy ounce. These pre-market movements provide an early indication of potential market reactions at the official open.
In early Asian trading on Monday, the U.S. dollar index edged up about 0.3%, while non-U.S. currencies generally weakened. The Australian dollar fell over 1% to a one-week low. USD/CHF opened down 0.34%, hitting a two-week low of 0.7667. NZD/USD opened down about 0.8% to a one-week low of 0.5945. EUR/USD opened down nearly 0.4% to a one-week low of 1.1764. GBP/USD opened lower by about 0.56%, falling to a more than one-month low of 1.3399. USD/JPY showed little movement, trading near flat around 156.14, up about 0.04%.
The oil market has become a central focus of the conflict. As the world's energy heartland, any supply disruption in the Middle East could trigger sharp price swings. A former White House energy adviser predicted that if there are no signs of de-escalation, oil futures could rise by $5 to $7 per barrel at the open. Iran, OPEC's fourth-largest oil producer, has hinted it might blockade the Strait of Hormuz, a critical narrow chokepoint connecting the Persian Gulf and the Arabian Sea. Should traffic through the strait be obstructed, oil prices could surpass the $100 per barrel mark.
Data shows that over 14 million barrels of oil per day transit the Strait of Hormuz, accounting for one-third of global seaborne crude oil exports. About three-quarters of this volume is destined for China, India, Japan, and South Korea. China, the world's second-largest economy, relies on this passageway for half of its crude oil imports. Any supply shock would rapidly transmit to global energy prices and deal a heavy blow to the economies of Asian oil-importing nations.
The future trajectory of the conflict is the market's primary concern. The Global Head of Research at Standard Chartered noted that investors had generally underestimated geopolitical risks. Although the U.S. dollar has weakened only slightly this year, commodity-linked currencies have performed strongly, reflecting the market's willingness to pay a higher premium for access to scarce resources and countries with improving terms of trade.
An analyst at FedWatch Advisors stated that the precision strike on Tehran's leadership significantly raises the tail risk of regime change, with the outcome highly uncertain. A rapid collapse of the Iranian regime could remove the threats of an oil blockade and nuclear escalation, potentially triggering a rebound in risk appetite. Conversely, if the conflict prolongs and exacerbates supply disruptions, risk-off sentiment is likely to persist. Energy prices have become the most immediate pressure point; sustained rises in crude oil would quickly push up inflation expectations, with a particularly severe impact on Asian economies. Following the market reopen, oil price movements and the exchange rates of the U.S. dollar against Asian currencies will be key indicators for assessing the severity of the impact.
Military actions have directly led to the closure of large swathes of Middle Eastern airspace, severely disrupting the aviation industry. Numerous airlines canceled hundreds of flights, with dozens of aircraft forced to divert, and some route services suspended at least until the end of next week. The disruption extended far beyond the Middle East, affecting international flights from places like Brazil and Australia that typically transit the region.
According to aviation data firm Cirium, over 1,800 flights into and out of Middle Eastern countries were canceled on Saturday, with another 1,400 flights in the region affected on Sunday. Qatar Airways announced a full, temporary suspension of operations, while Emirates confirmed that services at Dubai International Airport, one of the world's busiest airports, were completely halted. The global travel supply chain has suffered a significant rupture, highlighting the profound impact of the conflict on civilian infrastructure.
In summary, the large-scale strike by the U.S. and Israel against Iran has pushed the Middle East to the edge of a new cycle of high-risk confrontation. The death of Supreme Leader Khamenei further amplifies uncertainty. Financial markets, geopolitics, and energy supplies are facing unprecedented tests, requiring global attention to assess potential long-term consequences as the situation evolves.
