Hormuz Strait Shipping Monitor#

Sources to check#

Tier 1 - Primary data sources#

• Web fetch: https://www.ukmto.org/partner-products/jmic-products (JMIC updates)
• Web fetch: https://windward.ai/blog/ (Daily maritime intelligence)

Tier 2 - Iranian sources#

• Web fetch: https://www.tasnimnews.ir/en/ (search for "Hormuz" or "strait")
• Web fetch: https://www.farsnews.ir/en (search for "Hormuz")

Tier 3 - News & market data#

• Web search: "تنگه هرمز کشتی" (Farsi search for Hormuz shipping)
• Web search: "Brent crude oil gold price today"
• Web search: "VLCC tanker rate Hormuz insurance today"

Workflow#

Step 1-3: Data Collection#

1. Fetch Tier 1 URLs and extract latest updates
2. Fetch Tier 2 Iranian sources for new articles
3. Run Tier 3 web searches for breaking developments and prices

Step 4: Log Results#

Read current MONITOR_LOG.md. Append a new timestamped entry at the bottom.

CRITICAL FORMAT RULES — the website parser depends on exact formatting:

• Price values: plain numbers, NO markdown bold **, NO tilde ~. Example: $115.27/bbl not **~$115.27/bbl**
• VLCC rate: use K suffix. Example: $423K/day not $423,000/day
• All summary fields (新事件, 伊朗立场, 西方动态, 外交动态, 保险, Flash触发) MUST be written in Chinese
• Keep each summary field to ONE concise sentence (≤80 characters). Put detailed analysis in a sub-bullet if needed.
• Do NOT use markdown bold ** anywhere in field values

  - Vessels: 11/day vs prior 4-7/day = 57-175% increase
  - No ceasefire/breakthrough

Step 5: Trim Old Entries#

If MONITOR_LOG.md has entries older than 7 days, remove them.

Step 6: Flash Alert Check#

• Oil moved >5% since last entry? → FLASH
• Vessel count changed >50%? → FLASH
• Ceasefire/breakthrough/major attack detected? → FLASH
• Brent crossed $100 or $75? → FLASH

If FLASH: send immediate alert. If no FLASH: send brief summary.

Step 7: Update Website Data#

After writing MONITOR_LOG.md, run this command to update the website:

exec command: bash ~/hormuz-website/scripts/update_and_deploy.sh

This parses MONITOR_LOG.md into data.json and pushes to GitHub. Vercel auto-deploys on push. If the script fails, log the error but do not retry — the website will show the previous data until next cycle.
