A fifth of global oil flows through there. If that chokes off, prices spike.
On the twenty-seventh day of open conflict between Iran and Israel, global financial markets absorbed the weight of a war that has moved beyond two nations and into the arteries of the world economy. Crude oil surged, bond yields climbed to multi-year highs across three continents, and equity indices fell as investors recalibrated not merely for present disruption but for a prolonged era of elevated energy costs and tighter monetary policy. What unsettles markets most is not the missile fire itself, but the growing conviction that this conflict will outlast any near-term diplomatic gesture — and that its consequences, measured in barrels and basis points, may prove more durable than the fighting.
- Iran struck Gulf neighbors for the twenty-seventh consecutive day, with ballistic missiles intercepted over Riyadh and drones damaging Kuwaiti port infrastructure — signaling the war is spreading geographically, not contracting.
- The Strait of Hormuz, through which a fifth of the world's oil and gas flows, is increasingly choked by Iranian shipping restrictions, pushing Goldman Sachs to warn that crude could breach the 2008 record of $150 a barrel.
- Bond markets from Frankfurt to Tokyo flashed alarm — Germany's 10-year bund hit a 15-year high and Japan's a 27-year peak — as investors priced in the possibility that central banks will be forced to raise rates rather than cut them.
- Technology and cybersecurity stocks led equity declines, while energy names surged, drawing a sharp dividing line between sectors that suffer from inflation and those that profit from it.
- A brief diplomatic reprieve — Trump extending Iran's negotiating deadline by ten days — dissolved within hours as Friday's military escalation made clear that optimism had outpaced reality.
Global stock markets fell sharply on Friday as the Iran-Israel conflict entered its twenty-seventh day with no sign of abatement. The S&P 500, Dow Jones, and Nasdaq all declined between 0.74 and 0.94 percent, with futures pointing toward further losses. The immediate catalyst was a fresh round of missile exchanges, with Iranian strikes reaching into Saudi Arabia and Kuwait — Riyadh intercepted two ballistic missiles, and drones damaged the port of Shuwaikh. The Pentagon is reportedly weighing the deployment of up to 10,000 additional troops to the region.
The deeper wound to markets was economic. Crude oil jumped more than 2 percent, and bond yields surged across the globe — the U.S. 10-year Treasury reached 4.48 percent, its highest in over eight months, while Germany's equivalent hit a 15-year peak and Japan's a 27-year high. The International Energy Agency estimated the conflict is already cutting 7.5 percent of global oil supply, with losses potentially reaching 8 million barrels per day this month. Goldman Sachs warned that sustained disruption to the Strait of Hormuz — through which roughly one-fifth of global oil and gas flows — could push crude past the 2008 record of nearly $150 a barrel. More than 40 energy sites across nine Middle Eastern countries have already been severely damaged, threatening supply chain disruptions that could outlast the fighting itself.
The inflation implications rattled central banks. An ECB Governing Council member floated the possibility of an April rate hike, and market swaps now price a 65 percent chance of a European Central Bank increase at its April 30 meeting — a striking reversal from the easing cycle many had anticipated.
In equities, the split was stark. Most of the Magnificent Seven fell more than 1 percent, and cybersecurity stocks were hit hard after reports of AI security vulnerabilities, with CrowdStrike dropping more than 6 percent. Energy stocks moved in the opposite direction, with APA Corp, Chevron, Exxon, and others all gaining. A few isolated bright spots — Entergy on a major data center power deal, Argan on a blowout earnings report, Unity Software on strong AI-driven results — offered little comfort to the broader mood.
Compounding the anxiety, China launched two trade investigations targeting U.S. restrictions on Chinese goods, export controls, and barriers to green energy products — a retaliatory escalation that added geopolitical friction to an already volatile session. President Trump's extension of Iran's negotiating deadline by ten days had briefly lifted sentiment Thursday evening, but Friday's military developments made that optimism feel premature. Markets are now positioned for a prolonged conflict — one that keeps energy prices high, inflation persistent, and central banks in no position to offer relief.
The stock market opened lower on Friday as the escalating conflict between Iran and Israel sent crude oil prices climbing and bond yields to levels not seen in years. The S&P 500 fell 0.74 percent, the Dow Jones dropped 0.87 percent, and the Nasdaq 100 slid 0.94 percent—with futures suggesting the selling could deepen. The immediate trigger was straightforward: after 27 days of fighting, Iran and Israel exchanged missile fire again, with Iranian strikes reaching into several neighboring countries. Saudi Arabia reported intercepting two ballistic missiles headed for Riyadh. Kuwait said drones damaged the port of Shuwaikh, and another port facility took hits as well. The Pentagon, according to reporting from the Wall Street Journal, is weighing whether to send as many as 10,000 additional troops to the region.
The real damage to markets came not from the military exchanges themselves but from what they portend for energy supplies and inflation. Crude oil jumped more than 2 percent on the day. The 10-year Treasury yield climbed to 4.48 percent, its highest point in more than eight months. Germany's 10-year bund yield hit 3.13 percent—a level not reached in nearly 15 years. Japan's 10-year government bond yield rose to 2.39 percent, a 27-year peak. These moves reflected a growing conviction among investors that the war will persist, keeping energy prices elevated and forcing central banks to maintain higher interest rates for longer than previously expected.
The energy disruption is real and substantial. The International Energy Agency reported in mid-March that the conflict is already cutting off 7.5 percent of global oil supply, with projections that this month's losses could reach 8 million barrels per day. More critically, the Strait of Hormuz—the waterway through which roughly one-fifth of the world's oil and natural gas flows—has become increasingly choked. Iran's attacks on shipping in the strait, combined with its new demands that vessels provide crew lists, cargo details, and other documentation before passage, have forced Gulf producers to cut their output because they cannot export from the region. Goldman Sachs issued a stark warning: if the strait remains disrupted through March, crude prices could exceed the 2008 record high of nearly $150 a barrel.
The International Energy Agency also documented the physical toll. More than 40 energy sites across nine countries in the Middle East have been severely or very severely damaged, a destruction that could extend supply chain disruptions well beyond whenever the fighting ends. This prospect of prolonged inflation pressure is what truly unsettled the bond market. An ECB Governing Council member suggested that a rate hike in April is possible if evidence emerges that the war will be lasting and inflationary. Market swaps are now pricing in a 65 percent probability of a European Central Bank rate increase at its April 30 meeting.
Technology stocks bore the brunt of the selling. Most of the Magnificent Seven—Amazon, Tesla, Meta, Alphabet, and Microsoft—fell more than 1 percent. Cybersecurity names were hit particularly hard after a Fortune report suggested that Anthropic is testing an AI model with significant security vulnerabilities. Crowdstrike Holdings led the declines, dropping more than 6 percent, with Palo Alto Networks, Zscaler, and Okta all falling by similar amounts. Cryptocurrency-exposed stocks also slumped, with Bitcoin down more than 3 percent to a 2.5-week low, dragging down Coinbase Global and Riot Platforms.
Energy stocks, by contrast, surged. APA Corp climbed more than 3 percent, while Diamondback Energy, Chevron, Devon Energy, Exxon Mobil, Occidental Petroleum, and ConocoPhillips all gained more than 1 percent. A few bright spots emerged elsewhere: Entergy rose more than 5 percent after announcing a deal with Meta to supply 5.2 gigawatts of electricity to one of its data centers. Argan Inc. soared more than 35 percent on earnings that significantly beat expectations. Unity Software jumped more than 9 percent after reporting strong preliminary first-quarter results driven by its AI-powered advertising platform.
The market's anxiety was compounded by fresh trade tensions. China launched two investigations into U.S. trade practices, retaliating against similar probes initiated by the Trump administration earlier in the month. China's Ministry of Commerce said the investigations target U.S. restrictions on Chinese goods, export controls on advanced technology, and limits on bilateral investment in critical sectors, as well as barriers to trade in green products and renewable energy goods. The move added another layer of uncertainty to an already volatile session.
President Trump had briefly lifted sentiment late Thursday by extending his deadline for Iran to strike a deal with the United States by 10 days, to April 6, saying negotiations were progressing "very well." That optimism proved short-lived once Friday's military escalation became clear. The market is now bracing for a prolonged conflict that could keep energy prices elevated, inflation persistent, and central banks in tightening mode—a combination that historically pressures both stocks and bonds.

Why did the bond market move so sharply today? Usually that takes something really significant.
The fear is that this war doesn't end quickly. If energy stays disrupted for months, inflation stays high, and central banks can't cut rates. That's the nightmare scenario—stagflation.
But the Pentagon is sending more troops. Doesn't that suggest the U.S. is trying to contain it?
Containment and resolution are different things. More troops might prevent it from spreading, but they don't necessarily end the core conflict. And every day the Strait of Hormuz is partially closed, another day of lost oil supply.
The Goldman Sachs warning about $150 oil—is that realistic?
It depends entirely on whether the strait stays disrupted. If it does, yes. A fifth of global oil flows through there. If that chokes off for weeks, prices spike. If it clears, prices fall.
So the market is essentially betting the war lasts longer than the administration's April 6 deadline suggests.
Exactly. Traders are pricing in skepticism. The deadline extension was meant to calm things, but the actual military escalation today—missiles into Saudi Arabia, drone strikes on ports—that's what moved the needle.
Why did tech stocks get hit so hard if the real problem is energy and inflation?
Tech is the most rate-sensitive. Higher rates for longer means lower valuations for companies with earnings years away. Energy stocks benefit from the price spike, but growth stocks suffer from the rate environment.
