PRISM Weekly Digest: Second Week of March 2026

Mar Week 2, 2026 | Hormuz Is Closed — What the War Changed, and What It Couldn't

The waterway that carried 20% of the world's oil just shut down.

Iran's IRGC declared a full blockade of the Strait of Hormuz. "Not a litre of oil will pass." Tanker traffic dropped 70%, then effectively hit zero. On March 11 alone, three ships were struck. Off the port of Basra, two oil tankers caught fire from drone boat attacks.

Week three of the war. The S&P 500 fell for a third straight week to its 2026 low. U.S. GDP was revised down to 0.7%. Iran pulled out of the World Cup. Meanwhile, OpenAI released an AI that operates your computer, and BTS announced their return at Gwanghwamun.

The Lock on Hormuz

Week three of Operation Epic Fury. The war isn't ending — it's escalating.

On March 11, the IRGC declared the Strait of Hormuz fully closed to vessels linked to the U.S., Israel, and their allies. Over 150 tankers sit anchored outside the strait, waiting. Maritime intelligence confirms Iranian oil is still flowing through — Tehran has weaponized the waterway itself.

Markets responded with fear. WTI crude hit $98.71 per barrel. Brent topped $103.14. Oil prices have surged over 40% since the war began. U.S. gas prices jumped 70 cents per gallon since March 1, reaching $3.59. The S&P 500 broke through the 6,764 support level and hit its 2026 low after three consecutive weekly declines. The Dow fell 1.99%. The Nasdaq lost 1.26%.

Then came the scarier number. Q4 GDP growth was revised sharply down from 1.4% to just 0.7%. Prices rising while growth stalls — the ghost of 1970s stagflation is becoming real. Asian central banks, including South Korea's, are trapped between two bad options: fight inflation or protect growth. Neither works.

Iran's sports minister Ahmad Donyamali made it official: "Under no circumstances can we participate in a World Cup hosted by a regime that assassinated our leader." Iran is boycotting the 2026 FIFA World Cup. All three of their group-stage matches were scheduled in American cities — Los Angeles and Seattle. No nation has withdrawn from a World Cup this close to kickoff in the modern era. FIFA has signaled potential fines of hundreds of thousands of dollars and possible bans from future competitions.

American opinion is split — and silent. An NPR/PBS/Marist poll shows 56 to 70 percent of Americans oppose the war. Support for ground troops sits at barely 20%. Yet there are no large-scale street protests. The Irish Times asked the obvious question: "The majority oppose the war. So why aren't they protesting?"

Trump hasn't ruled out ground forces. "If necessary." The Pentagon says no U.S. troops are currently inside Iran, but the door is wide open. Reports indicate the U.S. and Israel have discussed deploying special forces to secure Iran's stockpile of highly enriched uranium.

AI Learned to Use a Computer

While the war shook the world, AI quietly crossed a threshold.

OpenAI launched GPT-5.4 on March 5. A million-token context window. 33% fewer factual errors. But the headline feature is something else entirely — native computer use. The AI can see your screen, move a mouse, and operate applications like a human. Draft an email, edit a spreadsheet, schedule a meeting — all from a single natural-language command. API pricing: $2.50 per million input tokens.

The same week, Apple sent the opposite signal. Its Gemini-powered Siri overhaul, planned for iOS 26.4, has been delayed due to internal development challenges. The features will now be spread across iOS 26.5 (May) and iOS 27 (September). Apple promised on-screen awareness and 10-step sequential actions powered by Google's 1.2 trillion parameter Gemini model. The gap between promise and delivery widened again.

In the first week of March alone, OpenAI, Alibaba, Meta, ByteDance, and others released over 12 major AI models — the most concentrated burst of AI releases in history. The AI arms race is moving faster than the one in the Middle East.

Gwanghwamun's Return

Through the war and market chaos, Seoul was vibrating on a different frequency.

BTS officially announced their first full-group comeback in four years. Their fifth studio album "ARIRANG" drops March 20 with a 14-track tracklist. On March 21, a comeback concert takes over Gwanghwamun Square — from Gwanghwamun Gate to City Hall intersection. 22,000 seats. Netflix secured exclusive worldwide livestream rights. A documentary, "BTS: The Return," premieres on Netflix March 27, with a world tour launching in April.

In the drama scene, "Siren's Kiss" is making waves. The tvN romance thriller starring Wi Ha-joon and Park Min-young debuted at 5.6% ratings in just two episodes, ranking first across all channels in its time slot. An insurance fraud investigator and a mysterious woman at the center of serial deaths — Wi Ha-joon, fresh off "Squid Game," plays dangerous charm once again.
