The market impact from the expected, but unrealized, loss of 3 million barrels/day from Russia was immense. The current Strait of Hormuz disruption is four to five times larger at 14 million barrels/day. This scale of shortage is historically unprecedented, meaning past events are poor guides for predicting market outcomes.

The UAE is leaving OPEC not just over oil policy, but as part of a larger strategic divergence from Saudi Arabia. Accelerated by the Iran war, the UAE is aligning with the US/Israel and betting on a post-carbon, tech-focused economy, while Saudi Arabia doubles down on being the last major oil producer, aligning more with China.

Major historical oil price movements were triggered by supply-demand imbalances of just 2-3 million barrels per day. A disruption at the Strait of Hormuz would impact 20 million barrels daily, a scale that dwarfs previous crises and renders standard analytical models inadequate.

Forecasters often miss that OPEC+ increases production based on demand for its own oil, not just overall global demand. Sanctions on rivals like Russia and Iran can boost demand for OPEC+ crude, prompting them to unwind cuts even when global demand growth seems weak.

The UAE's departure from the OPEC cartel could introduce real competition, potentially driving down global oil prices. This move signifies a shift in the global order, where Middle Eastern nations are asserting economic independence beyond oil production.

The UAE's decision to leave OPEC is a paradigm shift, effectively ending the era of significant global spare production capacity. While a post-crisis production race could temporarily lower prices, the lack of a buffer makes the entire system far more vulnerable to future supply disruptions.

The staggering rise of U.S. shale production disrupted the global oil market, fundamentally altering its power structure. This disruption directly pushed rivals Russia and Saudi Arabia to form the OPEC+ alliance in 2016 to collectively manage supply and counter American influence.

A prolonged blockade of the Strait of Hormuz would remove up to 16 million barrels of oil per day. This scale is so massive that government strategic reserves are inadequate to fill the gap. The only mechanism to rebalance the market would be catastrophic demand destruction.

While global spare oil capacity exists as a buffer, it is heavily concentrated in Saudi Arabia, the UAE, and Kuwait. During a conflict, if the Strait of Hormuz is effectively closed, this capacity becomes physically trapped and cannot be deployed to global markets, nullifying its role as a price stabilizer.
