Day 205 of the Middle East situation: Multiline conflict escalates, the contest over the Strait of Hormuz heats up

The Middle East situation is undergoing the most intense geopolitical upheaval since the outbreak of the conflict. Simultaneous upgrades on multiple fronts have placed the region’s security architecture under systemic risk. After Yemen’s Houthi forces launched ballistic missile strikes on Riyadh, Saudi Arabia’s capital, and Israel continued to expand military operations in southern Lebanon and the West Bank, what had previously been relatively isolated bilateral conflicts are evolving into a regional war. At the same time, the standoff between Iran and the United States over control of the Strait of Hormuz and the lifting of sanctions has entered a heated phase, with diplomacy and military deterrence proceeding in parallel—dealing severe blows to global energy supply chains and geopolitical stability.

At the factual level, the Yemen situation has become the core spark for this round of escalation. The Houthis claim that “sensitive” sites in Riyadh were attacked, and Saudi Arabia’s-led coalition later confirmed that its air-defense forces intercepted the ballistic missiles launched toward Riyadh. In response, Saudi Arabia is seeking U.S. support in striking targets rather than simply increasing arms supplies. Nawaaf Obaid, a senior researcher at King’s College London, said Saudi Arabia’s response to the Houthis would be “phased” and “large-scale,” coordinated with coalition partners. Turkey, while expressing support for Saudi Arabia, emphasized that its position is likely to remain “defensive,” noting that its allies are unlikely to directly participate in military action. Yemen’s military also said that in Marib it stopped a Houthi offensive, causing 12 deaths, highlighting the complex worsening of the internal situation in Yemen.

On the Iranian side, despite facing U.S. maritime blockades, its oil sales still hit a two-year high, showing the resilience of its energy export channels. Iran’s security minister laid out conditions for ending the war, including lifting the U.S. maritime blockade and ending warfare on all fronts, conveying these conditions to the United States through two mediators—Qatar and Pakistan. Iran’s military also raised objections to the U.S. Central Command’s claim that it escorted tankers carrying more than 100 million barrels of oil through the Strait of Hormuz, and warned U.S. allies not to launch attacks again. The chairman of the Iranian Parliament’s National Security Committee, Ebrahim Azizi, dismissed U.S. Treasury Secretary Scott Bessent’s claim that Iranians were standing in line for hours to buy gasoline, calling it “purely baseless lies.” In addition, Iran’s special committee approved regulating data-cable wiring that transits through the Strait of Hormuz, indicating that Iran is trying to expand its influence in the digital infrastructure sector.

The humanitarian crisis in Lebanon and the Palestinian territories continues to worsen. Israeli airstrikes destroyed a house between Haddat and Harris in southern Lebanon and hit medical personnel. Lebanon’s National News Agency reported that Israeli airstrikes hit multiple locations in southern Lebanon, including the Sarbin suburbs, Nabatieh al-Fawqa, and Kfar Tebnit. In the West Bank, Israeli forces detained several Palestinians; settlers attacked residents and tried to steal livestock, and they also cut the main water-supply pipeline of the town of Dkaqah, leaving about 700 Palestinians without water. Gaza health officials mourned the son who died in an Israeli airstrike, and the Gaza Ministry of Health said the death toll from Israel’s attacks in Gaza has risen to at least 73,910. The Israeli military said that in a shooting incident in the occupied West Bank, a driver was suspected of dying after allegedly ramming Israeli soldiers with a vehicle, and another attacker was arrested after firing from an assault rifle at settlers.

The U.S. response reflects its strategic dilemma in the Middle East. U.S. President Donald Trump shortened his weekend schedule at Mar-a-Lago, returning to the White House earlier than expected, and claimed he would either “eliminate Iran” or reach an agreement. The United States urged citizens to remain vigilant in the Middle East, saying the conflict between Saudi Arabia and the Houthis could “escalate quickly.” Egypt urged further action when meeting with the director of the CIA to address the situation in Gaza. Italy’s foreign minister said that Italy is “not in a state of war” in the Red Sea region, reflecting a cautious stance by European countries in getting involved in Middle East conflicts.

The impact of this escalation on global markets cannot be ignored. A new high in Iranian oil sales suggests that despite sanctions, its energy exports still show resilience, which could affect the global balance of crude oil supply and demand. The Strait of Hormuz, one of the world’s most important oil transport routes, means its security situation directly affects global energy security. Iran’s regulation of data-cable wiring could influence the stability of global internet infrastructure. In addition, instability in the Middle East could drive a rise in global risk-avoidance sentiment, pushing up prices of safe-haven assets such as gold and the U.S. dollar.

In the coming weeks, how the Middle East situation develops will depend on several key factors: the intensity of Saudi Arabia’s response to the Houthis; progress in negotiations between Iran and the United States on sanctions relief and control of the Strait of Hormuz; and the scope of Israel’s military actions in Lebanon and the West Bank. If Saudi Arabia launches a “large-scale” response, it could lead to further deterioration in Yemen’s situation and even trigger broader regional conflict. If Iran and the United States fail to reach a compromise, security risks in the Strait of Hormuz will remain, continuing to hit global energy markets. Moreover, Israel’s military operations in Lebanon and the West Bank could trigger more humanitarian crises and worsen regional instability.

For investors, the escalation in the Middle East implies that the geopolitical risk premium will persist. Energy sectors may benefit from rising oil prices, but they also face the risk of supply disruptions. Aviation and shipping may come under pressure due to higher fuel costs and risks to route safety. Safe-haven assets such as gold, the Swiss franc, and the Japanese yen may continue to strengthen. Investors should closely monitor policy changes by key actors such as Saudi Arabia, Iran, and Israel, as well as the progress of mediation efforts by international organizations such as the United Nations and the Gulf Cooperation Council.

Overall, the Middle East situation is at a dangerous tipping point, where even minor misjudgments or provocative actions could trigger uncontrollable chain reactions. The ability of all sides to balance military deterrence and diplomatic mediation will determine whether the situation moves toward easing or further deterioration. The global community needs to work together to bring all parties back to the negotiating table, resolve differences through dialogue, and prevent the Middle East from plunging into the abyss of full-scale war.
