📊 Top Signal

The U.S. is maintaining a naval blockade of the Strait of Hormuz despite oil hitting $121, and Trump just said publicly the blockade stays until Iran makes a deal. Iran's CII jumped 9 points in 24 hours — the biggest single-day move we've tracked this month — driven by market exposure (score: 20/25) and governance strain (14/25). Bellingcat published two investigations in the last 48 hours documenting satellite blackouts over Iranian strike sites and UAE censorship of damage assessments, suggesting the information war is as active as the naval one.

Here's why it matters: 20% of global oil moves through Hormuz. A sustained closure doesn't just spike prices — it rewrites supply chains. Every day this drags on, Asian refiners are locking in alternative (more expensive) crude sources, and that gets sticky. If this goes past 30 days, we're looking at structural repricing, not a crisis premium.

🌍 CII Movers

Iran 62 (▲+9) — Blockade holding, governance score climbing as sanctions bite harder. Canada 11 (▲+8) — Unexpected jump; monitoring for trade disruption or policy shift spillover. Sudan 60 (→) — Holding near crisis threshold; RSF-SAF clashes continue in El Fasher. Russia 59 (→) — Stable at elevated risk; conflict and governance scores locked in. Indonesia 14 (▲+3) — M5.3 quake 166 km west of Abepura; watching for aftershock escalation. Thailand 16 (▼-6) — Cooling after prior-week volatility.

Iran's 7-day trajectory is all over the map: 31 → 53 → 53 → 51 → 31 → 62. That's not a trend — that's reactive pricing to fast-moving events. When a CII swings 30 points in a week, trust the direction, not the precision.

⚠️ Crisis Watch

Hormuz standoff — Trump confirmed blockade continues until a deal. Oil up 4.5% today; energy majors up only 0.09%, meaning the market thinks this resolves or producers hedge it away. Crisis Group filed four Iran/Gulf updates in 48 hours — unusual velocity for them.

Sudan (CII: 60) — Approaching crisis threshold. RSF-SAF fighting ongoing in Darfur; 7-day average holding at 57-60 range. Displacement accelerating but not yet at mass-exodus levels.

Seismic: Japan cluster — 8 earthquakes M4.0+ in 24 hours, concentrated 146 km east of Miyako. Elevated aftershock risk. M5.4 was the largest; monitoring for infrastructure disruption.

📈 Markets & Exposure

Oil is $121 (+4.55%) on Hormuz, but here's the tell: energy sector equities are up only 0.09%. That's a hedge, not a bet. Traders are pricing in either a fast resolution or enough spare capacity to weather this. The reversal trigger is any signal of U.S.-Iran talks or a tanker making it through the strait with naval escort.

Gold down 0.86% — risk-off isn't dominating yet. Treasuries flat. USD Index down slightly. This is a targeted energy shock, not a broad flight to safety.

If Hormuz stays closed past 10 days, watch Malaysian and Singaporean refiners — they'll be first to lock in costlier long-term contracts, and that shows up in Asia-Pacific diesel spreads before it hits headline crude prices.

🔮 Scenario Spotlight

What if the Hormuz blockade lasts 30 days?

At 30 days, this stops being a geopolitical crisis and starts being a supply chain rewire. Asian buyers (Japan, South Korea, India) shift to West African and U.S. shale. Shipping costs spike as tankers reroute via Cape of Good Hope — adding 15 days and $2M/voyage. Iran's economy, already under strain (governance score: 14/25), faces hard-currency collapse, pushing CII toward 75+.

Historical comp: 2019 tanker attacks in the Gulf spiked oil 15% in 48 hours, but Hormuz never actually closed. A full closure has no modern precedent — the closest is the 1984-1988 Tanker War, when partial disruptions kept oil above $25/bbl (inflation-adjusted: ~$70) for years.

Cascades to watch: Lebanon (CII: 47), Jordan (CII: 38), and Egypt (CII: 40) all import refined products through Gulf routes. Fuel shortages there trigger governance crises within 60 days.

💬 One More Thing

Bellingcat's new "When Satellite Imagery Goes Dark" tool tracks deliberate blackouts over conflict zones. They caught commercial providers switching off feeds over Iranian strike sites in the Gulf. If you're doing damage assessment on infrastructure strikes, you now need to cross-reference multiple providers and flag gaps — the data itself is becoming a battlefield.
