Executive Summary
The United States struck hardened Iranian missile sites near the Strait of Hormuz this week with 5,000-pound “bunker buster” munitions, a sharp escalation intended to reopen a waterway that has largely fallen silent for commercial shipping and helped propel Brent crude above $100 a barrel. Iran, reeling from the Israeli killing of its top security official, Ali Larijani, responded with missile and drone barrages that have reached Israeli cities and Gulf capitals, while attacks on energy facilities and vessels deepened a supply shock the International Energy Agency called the largest in oil-market history. The war’s widening geography has exposed diplomatic strain inside the Western alliance, with Germany refusing to contribute naval forces to a strait-protection effort and a senior Trump administration counterterrorism official resigning in dissent. Away from the battlefield, Nvidia said it had secured U.S. export licenses to resume sales of its H200 artificial intelligence chip in China, a reminder that economic interdependence is being renegotiated even as Washington and its partners confront a regional conflict with global costs.

Nvidia Says It Has Export Licenses to Resume H200 Sales in China
Nvidia’s chief executive, Jensen Huang, said Tuesday that the company would restart production and sales of its H200 artificial intelligence chips to customers in China after receiving purchase orders and the necessary export licenses from U.S. authorities. The decision reopens a market that once accounted for more than a fifth of Nvidia’s data center revenue, even as Washington’s technology restrictions have tightened around advanced semiconductors and the systems used to train frontier A.I. models.
The move represented a reversal from Nvidia’s recent public posture. Just weeks ago, the company’s chief financial officer, Colette Kress, told analysts it had “yet to generate any revenue” from the H200 in China and had not included any such revenue in its near-term forecast. Nvidia had previously warned that export controls imposed last year had forced it to take about $5.5 billion in charges, a measure of how abruptly U.S. policy can alter the company’s product plans and inventory.
Mr. Huang has argued that cutting off Chinese researchers from American chips could backfire by accelerating domestic alternatives. “It’s a mistake to not have those researchers build AI on American technology,” he said last year. He also praised a December trade-policy change under President Donald Trump that allowed shipments of the more advanced H200 to proceed on the condition that the U.S. government receives a 25 percent cut of sales, an arrangement that has drawn criticism from lawmakers and China hawks who say any flow of advanced computing power bolsters Beijing’s military and surveillance capabilities.
It is unclear how durable the reopening will be. Chinese authorities have at times signaled discomfort with local firms importing restricted U.S. chips, and Washington’s licensing decisions can be tightened or reversed with little notice. Even if the H200 returns, Nvidia faces increasingly capable domestic rivals in China and must juggle a product portfolio that already includes purpose-built, downgraded chips designed to comply with earlier rules. The company’s next earnings report will be watched closely for signs that the H200 channel is meaningful rather than symbolic.
Geopolitics & Security
U.S. Uses 5,000-Pound Bombs on Iranian Missile Sites by Hormuz
The U.S. military said it struck hardened Iranian missile sites near the Strait of Hormuz on Tuesday using 5,000-pound GBU-72 penetrator bombs, escalating a campaign that Washington has framed as necessary to restore shipping through one of the world’s most important oil chokepoints. U.S. Central Command announced the operation as Iran’s attacks on vessels and threats to commercial traffic have effectively choked off transit, leaving shipowners and insurers unwilling to risk passage even when naval forces are nearby.
Iran responded with missile and drone attacks that hit Israel and crossed the skies of Gulf states, as Tehran’s leaders vowed that pressure on the strait would not ease. The exchange came after Israel confirmed it had killed Ali Larijani, Iran’s secretary of the Supreme National Security Council and, according to Iranian accounts, a pivotal figure in directing the country’s war strategy following the earlier reported killing of Iran’s supreme leader, Ayatollah Ali Khamenei, in late February. The conflict, ignited by U.S. and Israeli attacks on Feb. 28, has since become a grinding contest in which both sides have sought to demonstrate escalation dominance without tumbling into a wider war they cannot control.
The strikes also exposed political stress within the Western alliance. Germany’s chancellor, Friedrich Merz, said Washington had not consulted Berlin and criticized the strategy as lacking a “convincing plan,” adding that Germany would not contribute naval forces to secure the strait while fighting continues. NATO’s secretary general, Mark Rutte, said allies were discussing “the best way” to reopen the passage, but public reluctance from a major European power underscored how difficult it may be to assemble a multinational force robust enough to change the risk calculus of shipping companies.
At home, the Trump administration faced visible dissent. Joe Kent, the director of the National Counterterrorism Center, resigned and said Iran “posed no imminent threat” to the United States, a rare public rupture as Mr. Trump suggested on social media that the U.S. could “finish off” Iran’s regime while leaving other nations to secure the strait. Whether the latest bombing run translates into safer seas remains uncertain; Iran’s ability to harass ships with missiles, drones and mines has proven resilient, and a single successful strike on a tanker can be enough to freeze traffic for days.
Israel Claims Another Senior Kill as Iran Adapts Tactics With Cluster Munitions
Israel’s defense minister, Israel Katz, said this week that Israel had killed Iran’s intelligence minister, Esmail Khatib, in an airstrike, a claim that Iranian officials have not fully confirmed in public. Mr. Katz went further, describing a policy that would widen the target set: he said Prime Minister Benjamin Netanyahu and he had authorized the military to “eliminate any senior Iranian official for whom the intelligence and operational circle has been closed, without the need for additional approval.” Iran’s president, Masoud Pezeshkian, condemned what he called a “cowardly assassination,” while maintaining that the state’s structure remained intact.
The alleged killing, if verified, would follow the assassination of Mr. Larijani and the reported death of Gholamreza Soleimani, the commander of Iran’s Basij paramilitary force, in what appears to be an intensive Israeli effort to degrade Tehran’s security apparatus. The campaign has coincided with strikes on Iranian energy assets, including damage reported at the South Pars gas field, and with attacks on residential buildings in Tehran that Iranian relief organizations said killed civilians. Israeli officials have argued that decapitating leadership shortens wars; critics say such tactics can harden resolve, generate uncontrollable succession struggles or increase the likelihood of attacks on civilians.
Iran has shown signs of tactical adaptation as the exchange has intensified. On Wednesday, Iranian missiles using cluster munitions killed an elderly couple in Ramat Gan, near Tel Aviv, a rare breach that drew attention to the limits of even advanced air defenses under sustained assault. Lt. Col. Nadav Shoshani, an Israeli military spokesman, said Iran has increasingly turned to cluster weapons that are “very difficult to stop,” even when the missile carrying them is intercepted.
The steady pace of barrages has strained interceptors and exposed disputes about performance that are hard to resolve in real time. Israeli officials have touted high success rates, while some outside weapons experts have questioned whether interception claims match battlefield evidence, citing the visibility of warheads over major cities and the costs of replenishment. The truth may lie between propaganda and skepticism: layered defenses can reduce casualties without eliminating them, and Iran needs only occasional penetrations to achieve strategic effects. How Israel responds to the use of cluster munitions against population centers—especially as it widens strikes inside Iran—could determine whether the war accelerates or grinds on.
Hormuz Closure Deepens Shipping Crisis as Gulf States Seek Workarounds
Iran’s sustained attacks on merchant traffic in and around the Strait of Hormuz have pushed the global shipping system into a scramble reminiscent of earlier choke-point crises, but on a far larger energy base. The disruption has slowed or stopped the movement of nearly a fifth of the world’s oil and a substantial share of liquefied natural gas exports, while transport firms have raised prices sharply and airlines have rerouted flights around Gulf airspace restrictions that have pinched hubs like Dubai and Doha.
The United Arab Emirates, backed by Australia, won an emergency condemnation at the International Maritime Council, arguing that Iran’s actions have “triggered severe global energy shocks.” Dubai has moved to blunt the commercial damage by activating a “green corridor” logistics channel with Oman, shifting some flows toward sea-air routes that bypass the strait. Such measures may help keep high-value goods moving, but they cannot substitute for the scale of oil and gas that normally transits the narrow passage each day.
An International Energy Agency assessment described the situation as “the largest supply disruption in the history of the global oil market,” surpassing even the shocks of the 1970s. Yet markets have been slow to price a prolonged crisis at full severity, an apparent bet that naval power, diplomacy or sheer economic pressure will reopen the lane. A senior U.S. official, in a remark that drew attention for its bluntness, said that “the only thing prohibiting transit… is Iran shooting at shipping,” underscoring that the barrier is not navigational but coercive.
That gap between physical reality and financial expectations may not last. Each day that tankers remain stranded, insurers raise premiums, and governments confront the prospect of fuel rationing, emergency stockpile releases and renewed inflation. The I.E.A. has forecast a gradual resumption of traffic by late March, but that projection assumes a political decision in Tehran to tolerate passage—or a military effort able to secure it at a scale that changes commercial behavior. Neither outcome appears imminent, and the longer ships idle, the more pressure builds for risky convoys or for strikes that could broaden the war.
Israel Hits Central Beirut as Ground Forces Meet Hezbollah Resistance
Israel expanded its military campaign in Lebanon on Wednesday, striking central Beirut and destroying two bridges over the Litani River, according to Lebanese authorities and the Israeli military. Lebanese officials said at least 12 people were killed in the capital. Israel said it demolished a 15-story building it claimed was used to store cash for Hezbollah and targeted the river crossings to disrupt the group’s use of state infrastructure.
The operations marked a widening of a campaign that had been concentrated in Hezbollah’s southern strongholds, and challenged a core idea of the U.N.-brokered 2006 cease-fire, Resolution 1701, which sought to keep armed groups north of the Litani. Israel has long argued that Hezbollah violates the arrangement; the bridge strikes suggested Israel is now willing to treat state infrastructure as an extension of Hezbollah’s military network, a logic that Lebanese officials and humanitarian groups have said places civilians at heightened risk.
On the ground, Israeli troops pushing deeper into southern Lebanon met stiff resistance in areas including Khiam and Aita al-Chaab, as Hezbollah acknowledged “heightened clashes.” Israel described its push as a “limited ground operation,” but the scale of forces amassed along the border—four brigades and tank columns, according to accounts from the region—has raised fears of a larger invasion.
The human toll is rising quickly. Lebanese authorities say the fighting has killed at least 968 people in Lebanon, including 111 children, and forced more than a million from their homes. The U.N. human rights office has suggested some Israeli attacks may amount to war crimes, accusations Israel has rejected in past conflicts as politically motivated and detached from the realities of fighting an embedded militia. Whether the war in Lebanon becomes a primary front or remains an extension of the Israel-Iran conflict may depend on how long Hezbollah can sustain defenses and whether Israel’s leadership believes its aims are achievable without committing to a prolonged occupation.
Ukraine Sends 200 Drone Specialists to Gulf States as Defense Links Tighten
President Volodymyr Zelensky of Ukraine said more than 200 Ukrainian military experts have deployed to Gulf countries, including the Emirates, Qatar, Saudi Arabia and Kuwait, to help defend against Iranian-designed Shahed drones. He framed the move as a direct response to the Tehran-Moscow relationship, arguing that Iranian drones now “contain Russian components” and that Russia upgraded the technology it received.
The deployment highlights how the war in the Gulf is pulling in actors far beyond the region, and how Ukraine—once primarily a recipient of Western weapons—has become an exporter of hard-won operational expertise. Gulf governments have invested heavily in air defenses but have struggled with the cost curve of drone warfare, where inexpensive attackers can force defenders to fire expensive interceptors. Ukrainian teams, after years of adapting to mass drone attacks, bring tactics for layered defense, electronic warfare and rapid repair that some regional militaries lack.
The shift is also political. Gulf states have tried to keep channels open to multiple powers, including Russia, while relying on U.S. security guarantees; Ukraine’s presence suggests a more pragmatic alignment built around specific capabilities rather than formal alliances. It could also complicate diplomacy: Tehran is likely to see foreign specialists aiding Gulf defenses as part of a broader coalition, even if Kyiv’s primary motives are tied to its own war.
At the same time, the region’s defense integration is becoming more visible. Israel and the United Arab Emirates have quietly shared early-warning data for years, and discussions have circulated about expanding coordination with Bahrain and Saudi Arabia. The sustainability of such networks, however, depends on inventories and political will; U.S. officials have privately worried about interceptor depletion in extended conflicts, and critics dispute how effective defenses are against certain classes of ballistic missiles. If the war endures, Gulf states may face a choice between deeper integration with Israel and the United States or renewed efforts to hedge with Iran to reduce the volume of incoming fire.
Economy & Markets
Oil Exports From the Middle East Plunge, and Forecasts Turn Dire
Oil exports from the Middle East have collapsed by as much as two-thirds since February, removing an estimated 7 to 10 million barrels per day from global supply and prompting some analysts to warn that prices could spike to $150 to $200 a barrel if the disruption persists. Shipping trackers including Kpler and Vortexa have shown daily shipments falling from more than 25 million barrels a day in February to as low as 7.5 million barrels by mid-March, a decline driven by the effective closure of the Strait of Hormuz and by production cuts as storage fills in producing states.
Brent crude has already surged more than 40 percent since the war began on Feb. 28, trading above $100 a barrel and, in some reports, reaching about $112 after Iranian strikes hit key energy facilities. The shock has rippled quickly through refining. China’s Sinopec has cut processing rates by about 10 percent, while Japanese refiners have run at roughly 69 percent capacity, a sign that importers are bracing for a prolonged shortage rather than a brief price spike.
The White House has moved to soften domestic constraints, including suspending the Jones Act to allow foreign vessels to ship fuel between U.S. ports. Vice President JD Vance called the measure a response to a “temporary blip,” but analysts have said it does little to address a global supply gap of the current magnitude. Strategic petroleum reserve releases can buy time, but even large drawdowns cannot replace a sustained loss of Hormuz transit, especially if Gulf producers cannot export what they pump.
The greatest uncertainty remains political rather than technical. Markets appear to be pricing some chance of quick relief, either through a negotiated corridor or an effective escort and clearance effort that convinces insurers and owners to reenter the strait. But the longer tankers sit idle and energy infrastructure remains under threat, the more the crisis begins to resemble a structural shock: higher freight costs feed inflation, governments face public anger over fuel prices, and companies begin planning around scarcity rather than volatility. In that environment, even small attacks can carry outsized economic weight.
Regional Developments
Iraq Restarts Limited Exports Through Turkey as Basra Flows Falter
Iraq said it would resume limited oil exports through the Kurdistan Region pipeline to Turkey’s port of Ceyhan, offering one of the few partial workarounds to the Hormuz crisis. Iraq’s state-owned North Oil Company said it would pump about 250,000 barrels a day, a fraction of the 3.5 million barrels a day the country typically ships from Basra through the strait. The decision followed an agreement between Baghdad and the Kurdistan Regional Government after years of dispute that had kept the pipeline largely shut.
The restart comes as Iraq’s oil production has slumped to around 1.5 million barrels a day because of the war and the bottlenecks around storage and transport. Even if the northern route holds, it cannot replace the scale of southern exports, and it carries its own vulnerabilities: the pipeline runs through contested political terrain and depends on Turkey’s willingness to keep the outlet open amid regional pressure.
Security risks in Iraq are also rising. The U.S. Embassy in Baghdad has been hit by projectiles for the second time in less than 24 hours, and Iraqi militias have claimed responsibility for earlier attacks. Separately, reports have said more than 200 American defense contractors are stranded at an air base near Baghdad amid warnings of possible attacks by Iran-aligned groups after Ramadan ends, a situation that could force Washington into retaliatory action even if it seeks to limit escalation.
NATO Adds Patriot Coverage in Turkey as Gulf Capitals Brace for More Strikes
NATO confirmed that an additional U.S.-made Patriot missile defense system would be deployed to Turkey’s Incirlik Air Base after Turkish authorities intercepted three Iranian ballistic missiles in Turkish airspace. Turkey has sought clarification from Iran and warned of its right to respond, while avoiding the kind of public confrontation that could lock it into a broader war. The Patriot deployment, though defensive, is a reminder that the conflict’s airspace is expanding beyond Israel and the Gulf, placing pressure on states that have tried to stay on the margins.
Across the Gulf, governments have issued recurring civil defense warnings as Iranian missiles and drones have targeted or traversed the region. The United Arab Emirates has reported responding to “incoming missile and drone threats,” with explosions heard in Dubai, while Bahrain has activated national sirens and urged residents to seek shelter during barrages. Al Jazeera has reported that Iran has fired more than 3,000 projectiles at Gulf Cooperation Council countries in three weeks, with more than half aimed at the UAE, a pace that strains interceptors and tests public tolerance.
For now, Gulf states are trying to protect their energy assets while avoiding being pulled fully into the war. Yet the targeting of Qatar’s Ras Laffan LNG complex and precautionary shutdowns in the UAE and Saudi Arabia have shown how quickly economic targets become strategic ones. Whether the region moves toward a formalized, integrated air defense posture—or instead pursues separate deals with Tehran to reduce exposure—may hinge on how long the Hormuz blockade endures and whether Washington can articulate a strategy that allies view as credible rather than improvised.
