Saudi Arabia, the world's largest oil exporter, has begun reducing its overall petroleum output, including crude oil, following similar moves by the United Arab Emirates, Kuwait, and Iraq. This decision comes as the strategically vital Strait of Hormuz is effectively blocked by Iranian military forces, and Middle Eastern oil producers are nearing maximum storage capacity.

The new Middle Eastern conflict has effectively shut down the Strait of Hormuz, a narrow channel connecting the Persian Gulf to the open sea, following threats from the Iranian military to global shipping. This blockage has obstructed energy exports from key global producers, causing a sharp rise in the international oil benchmark, Brent crude futures. The resulting surge in oil and gas prices is expected to trigger a new wave of inflation, potentially delivering a significant macroeconomic shock reminiscent of "stagflation" to the global economy. Saudi Aramco, the state-owned energy giant, has declined to comment.

According to the latest statistics, Saudi Arabia produces approximately 10 million barrels of oil per day and exports about 7 million barrels, far exceeding other major producers like Russia and the United States. While the U.S. is the largest producer, its net exports remain lower than Saudi Arabia's due to high domestic consumption. Russia, the second-largest exporter, faces constraints on export stability due to geopolitical factors and sanctions.

Saudi Aramco has diverted some of its shipments from the usual routes through the Strait of Hormuz to the Yanbu export terminal on the Red Sea. However, the pipelines handling these exports lack the capacity to fully replace the massive energy export system reliant on the Strait.

According to Antoine Halff, Co-founder and Chief Analyst at geospatial analytics firm Kayrros, producers around the Persian Gulf, including Saudi Arabia, the UAE, Kuwait, and Iraq, collectively have just over 100 million barrels of storage capacity remaining, about one-third of their total. Halff noted that actual usable levels are even lower, as storage tanks are rarely operated above 80% of practical capacity.

The disruption in Middle Eastern energy transport has halted both production and the movement of large tankers. The Strait of Hormuz is critical for the transit of approximately 20-30% of the world's crude oil and natural gas.

At the time of writing, Brent crude futures had surged over 13%, remaining above the key $100 per barrel mark after earlier gains of up to 30%. The primary driver is the complete halt of energy transit through the Strait of Hormuz, leading to output cuts by major Middle Eastern producers. The early session price increase marked the largest single-day gain since April 2020 and the highest price level since June 2022, extending a 27% rally from the previous week.

Oil prices briefly soared to around $120 per barrel on Monday, a nearly 80% increase since the outbreak of the Iran conflict. The market is interpreting this as a stagflationary shock, combining higher inflation with a more pessimistic economic outlook.

A recent report from Wall Street giant JPMorgan indicates that supply disruptions among Persian Gulf producers have accelerated beyond expectations just seven days into the Middle East conflict. The report states that while current production cuts are around 2 million barrels per day, driven by saturated storage and a severe tanker shortage, regional cuts are expected to exceed 4 million barrels per day by Friday, March 13th. This figure implies that global oil supply will lose the equivalent of more than twice Iraq's total exports in just two weeks.

Pessimistic expectations for the global economy heading towards stagflation accelerated further following the U.S. President's recent statement that parts of Iran have not been targeted by U.S. and Israeli airstrikes, and his comment that $100 oil is a "very small price to pay for safety and peace." This has severely damaged prior market optimism that the conflict would remain relatively contained.

Whereas investors were tentatively trading on stagflation fears just days ago, the sentiment has now shifted to a more defined trend: investors are pricing in a deeper, more prolonged oil supply shock. This shock could squeeze global economic growth while re-igniting inflation metrics. Government bond yields have surged in response, fueling the so-called "stagflation trade." In equity markets, the sell-off since the escalation of Middle East tensions has wiped out approximately $6 trillion in global market capitalization.
