BRICS Faces Major Test as Iran Crisis Threatens Global Oil

BRICS oil markets are under serious pressure right now. The Iran crisis has pushed global oil prices to a 19.5-month high after the Strait of Hormuz — the passage that handles roughly a fifth of the world’s oil — closed following the US-Israeli military offensive against Iran. On March 5, April WTI crude closed up $6.35, or 8.51%, and gasoline also hit a 1.75-year high. BRICS oil trade runs through some of the most contested energy corridors on the planet, and at this point, the bloc’s energy security and its de-dollarization agenda are being tested at the same time.

Hormuz Closure Cuts Off BRICS Oil Flows

The strait closure left Gulf oil with basically nowhere to go. Iraq and Saudi Arabia started cutting production as storage at key terminals filled up faster than expected — Kayrros reported Wednesday that four of Saudi Arabia’s Ras Tanura refinery tanks were already full, and the Ju’aymah terminal on the country’s east coast is also running out of spare capacity. The Iran crisis is, right now, directly blocking BRICS oil flows out of some of the most critical export routes in the world.

Iran’s Islamic Revolutionary Guard Corps warned ships that vessels were

“could be at risk from missiles or rogue drones.”

Goldman Sachs put the real-time risk premium for crude at $18 per barrel — its estimate of what a six-week full halt to tanker traffic through the strait actually costs the market. An Iranian drone also caused a major fire at the UAE’s Fujairah oil hub on Tuesday, and separate drone attacks forced Saudi Arabia to shut down its Ras Tanura refinery, which processes 550,000 barrels per day.

China Moves as Global Oil Prices Keep Climbing

Beijing told its largest refiner on Thursday to suspend exports of diesel and gasoline, citing the Persian Gulf conflict. That move is pushing global oil prices even higher, and at the time of writing there is no signal from China that it is getting reversed. US Defense Secretary Pete Hegseth had this to say about the ongoing offensive:

“Death and destruction from the sky all day long.”

Israel has also indicated weeks more of conflict ahead. The Guardian reports that the US-Israeli offensive has killed over 1,000 civilians since it started, including scores of children. Iran is retaliating — hitting US military bases and civilian infrastructure across the region, including in Oman. The BRICS oil sector, which depends on stable Persian Gulf transit, has no immediate buffer for a conflict of this scale.

BRICS De-Dollarization Plans Hit a Wall

The Iran crisis has also landed directly on BRICS de-dollarization efforts, and the timing is bad. BRICS oil producers were already navigating US sanctions on Russian and Iranian crude, and this escalation adds another layer of risk. Wang Tao, former VP of ZTE and a regular voice on China’s strategic direction, had this to say in a recent Think BRICS interview:

“The BRICS countries possess the greatest economic development potential in the world. The future demand for energy is immense. It’s necessary to decouple all of these areas of infrastructure from those former hegemonic ones established by predatory nations.”

On the 2026 BRICS Pay rollout and cutting ties with SWIFT, Wang also stated:

“The BRICS payment system, or BRICS Pay, which originates from Russia, is a very important example of testing to such a crucial wealth-creating infrastructure. It is equally important to quickly decouple from the SWIFT system.”

OPEC+ said Sunday it will add 206,000 bpd in April — well above the 137,000 bpd analysts had expected. Even so, that extra supply is being absorbed by the disruption. Vortexa data shows around 290 million barrels of Russian and Iranian crude sitting in floating storage, over 50% more than a year ago. BRICS oil trade through these corridors has no clear path out right now, and the bloc’s wider BRICS de-dollarization push is also under strain as long as BRICS oil stays trapped in conflict zones and sanctioned shipping routes.
