Iran's oil exports have collapsed over 80% under the US naval blockade. Pre-war baseline: ~1.5 mb/d. Current estimate: ~300 kb/d. The carrier battle group accomplished what decades of sanctions could not — physical interdiction of Iran's primary revenue source.

Iran Oil Exports Collapse >80% Under US Blockade
Iran's crude oil exports fall over 80% as US naval blockade cuts the country's primary revenue source.

What Happened
Sanctions failed for years. Iran ran a shadow fleet. Ships can dodge paperwork. They cannot dodge a carrier battle group. This is qualitatively different.
Oil accounts for ~60-70% of Iran's government revenue. An 80% export cut means roughly half the government's income is gone. Economically unsustainable beyond 3-6 months without alternative financing. The residual ~300 kb/d likely flows overland — pipeline to Turkey, possibly Pakistan — but the maritime channel is functionally closed.

Iran's oil exports have collapsed by more than 80% as US naval blockade cuts the country's primary revenue source. Economic siege in effect.

@TankerTrackers
Iranian crude loadings near record lows. Shadow fleet activity minimal. Naval interdiction proving far more effective than sanctions ever were.

BRICS News: Iran oil exports collapse >80%
Words vs Actions
Words
- US: 'Maximum pressure campaign to end Iran's nuclear program'
- Iran: 'Oil exports continue despite sanctions' (pre-war claim)
- China: continued Iran oil purchases (pre-war)
Actions
- Iran exports down >80% — blockade is physically effective
- US became net crude exporter same week — replacement supply flowing
- Chinese imports from Iran presumably collapsed with exports
- One LNG tanker crossed Hormuz — blockade porous but devastating
The blockade's effectiveness is now quantifiable. Iran's pre-war sanctions evasion (shadow fleet, Chinese imports) has been physically broken by naval interdiction. This is qualitatively different from sanctions — ships can avoid sanctions, they cannot avoid a carrier battle group. The 80% figure suggests a small residual flow (pipeline to Turkey? overland to Pakistan?) but the maritime channel is functionally closed.
Model Impact
Iran Export Collapse → L0 Energy Monopoly in Action
Iran's >80% export collapse quantifies the blockade's effectiveness. Pre-war, Iran exported approximately 1.3-1.8 mb/d, primarily to China. The collapse means ~1-1.4 mb/d removed from the market. Combined with the US achieving net crude exporter status (Event 6), this is the L0-global-plan thesis made observable: supply removal via military action, supply replacement via US production.
The Skeptic and Adversary perspectives challenge the L0 interpretation. The Skeptic notes US net exporter status may be import-reduction (Hormuz cutting Middle East supply to US) rather than export-increase. The Adversary notes China's alternative supply architecture may absorb Iranian crude via non-maritime channels. Final synthesis: the directional reading is correct (Iran supply destroyed, US supply growing), but the monopoly interpretation requires distinguishing between market restructuring and market control.
