Monday opens as the most consequential market day since the COVID crash of March 2020.

On Saturday February 28, the United States and Israel launched joint strikes on Iran under Operation Epic Fury, killing Supreme Leader Ali Khamenei along with dozens of senior Iranian officials.

Iran responded with roughly 300 ballistic missiles targeting US military bases across the Gulf, civilian airports in Kuwait and the UAE, and Israeli territory.

The Houthis declared resumption of Red Sea attacks. Maersk suspended all Strait of Hormuz transits until further notice. About 240 ships are clustered near the strait with shipping activity down 40 to 50 percent.

This is not a geopolitical risk premium being priced in. This is a live military conflict with direct consequences for 20 percent of global oil supply.

Oil is the immediate shock Brent crude surged as much as 13 percent to above $82 per barrel in early Asian trading before pulling back toward $79. WTI jumped 8.6 percent to $72.61. The Iranian Revolutionary Guard is transmitting through maritime radio channels that the Strait of Hormuz is now closed, though no formal official declaration has been made. ​

Goldman Sachs placed an $18 per barrel real-time risk premium on crude Sunday. Wood Mackenzie warned oil could surpass $100 per barrel if tanker operations are not promptly reinstated. Citi projects Brent between $80 and $90 in the primary scenario over the next week. ​

The Strait of Hormuz handles approximately 20 percent of the world’s oil supply. A ship that enters the strait takes time to exit. Laden vessels are idling away and rerouting to Fujairah to wait for alternative arrangements. Even if the strait reopens within days, the disruption to tanker scheduling, insurance pricing, and cargo routing will take weeks to clear.

The first oil tanker was attacked in the Strait of Hormuz Sunday according to Oman authorities. That transforms theoretical closure risk into confirmed hostile action against commercial shipping. Insurers will now price war risk into every Gulf transit, raising effective shipping costs even if the physical waterway stays passable. ​

The consequence for inflation is severe. The Cleveland Fed already projected core PCE at 3.25 percent for Q1 2026 before this weekend. Trump’s 15 percent tariffs. Now add an oil shock on top of that. Core PCE pushing toward 3.5 percent or higher by Q2 is not a tail risk. It is the base case.

Bond buyers are in an impossible position Ten-year US Treasury yields fell to approximately 3.95 percent as capital flooded into US bonds as a safe haven. That is the standard geopolitical flight to safety trade. When the world gets dangerous, money buys US Treasuries. ​

But this particular safe haven trade contains a contradiction. Buying bonds while an oil shock, tariffs, and military conflict simultaneously push inflation higher means purchasing an asset whose fundamental value is being eroded in real time. If inflation hits 3.5 percent and the Fed cannot cut because the economy is being hit by inflationary shocks from multiple directions, bond holders at 3.95 percent yields are locked into negative real returns.

The 1973 Arab oil embargo created exactly this dynamic. Oil quadrupled. Inflation surged. The Fed was slow to respond. Bond holders suffered years of negative real returns as the central bank tried to balance growth support against inflation fighting. The current setup has more inflationary inputs than 1973. Tariffs, military conflict, and oil disruption are all hitting simultaneously.

Equity positioning faces the worst possible combination Dow futures fell 622 points on top of Friday’s 570 point cash close decline, meaning the Dow enters Monday already down over 1,100 combined points from Thursday’s close. American Express fell 8.16 percent and Goldman Sachs dropped 7.64 percent leading Friday’s losses before the Iran news even landed. ​

S&P 500 futures dropped roughly 1.5 to 2 percent in overnight trade. That is the immediate mechanical repricing. The more important question is what happens to earnings forecasts. ​

Airline stocks face fuel cost explosions and Gulf route disruptions. Shipping companies face war risk insurance premiums that may make some routes economically unviable. Auto manufacturers dependent on Gulf petrochemical supply chains face input cost spikes. Consumer companies already struggling with flat retail sales now face energy-driven cost inflation.

Defense stocks will gap higher at Monday’s open. Lockheed Martin, Raytheon, General Dynamics, BAE Systems, Rheinmetall, and Israeli defense companies across the board will benefit from the largest US military operation since the 2003 Iraq invasion. That is real revenue for these companies. Multi-year defense procurement cycles just got accelerated. ​

What Khamenei’s death means geopolitically Ali Khamenei ruled Iran since 1989, shaping its anti-Western policies, nuclear ambitions, and support for proxy militias across the Middle East. His death removes the central authority figure who coordinated Iran’s regional strategy. The Islamic Revolutionary Guard Corps, Hezbollah, Hamas, and the Houthis all operated under his direction. ​

Trump declared Operation Epic Fury aims to destroy Iran’s missile and military capabilities, prevent Iran from obtaining nuclear weapons, and topple the Iranian regime, projecting the operation will take one month or less. Analysts broadly contest whether those objectives can be achieved in that timeframe.

Iran’s UN ambassador condemned the strikes at a Security Council meeting, calling the attack a sovereignty violation. Iran launched roughly 300 ballistic missiles in retaliation against US bases in Jordan, Kuwait, Bahrain, Qatar, Iraq, Saudi Arabia, and the UAE. Hezbollah declared war against Israel. The Houthis resumed Red Sea attacks.

The consequence is that this is not a surgical strike with a defined endpoint. It is an open-ended military conflict involving Iran, Israel, the US, Hezbollah, and the Houthis simultaneously. Each of those actors has the capacity to escalate further, and none of them has an obvious off-ramp.

Indian markets and global contagion Indian equity markets opened sharply lower Monday with the Nifty 50 falling below 24,900 and the BSE Sensex dropping over 1,000 points. Foreign portfolio investors had already sold Rs 7,536 crore of Indian equities on Friday before the Iran news. India imports approximately 85 percent of its oil needs, a significant portion of which transits the Strait of Hormuz or originates from Gulf producers. ​

An oil price at $80 to $100 per barrel severely damages India’s current account balance, weakens the rupee, and imports inflation into an economy that the Reserve Bank of India had been carefully managing. The Modi government’s trade deal with Trump reducing tariffs from 25 to 18 percent looks less significant against an oil shock that will cost India far more in import bills.

Gold at $5,350 per ounce and approaching its January all-time high of $5,608 is the clearest market signal. The January rally was driven by currency debasement fear and Fed independence concerns. That pushed gold to $5,608 before the Warsh nomination crashed it to $4,700. It has now recovered most of those losses and added a genuine war premium on top. ​

The market enters Monday navigating a live military conflict, an oil supply disruption affecting 20 percent of global supply, 25 percent tariffs taking effect Tuesday, core inflation already at 3.25 percent, and equity valuations that were already being questioned before any of this happened. Those are not conditions that resolve quickly. The regime has changed again, and this time the catalyst is not a Fed Chair nomination. It is a war.
