The foundational pact of the modern Middle East — US military protection in exchange for exclusive, USD-denominated oil pricing — is facing its most serious test since inception. With Iran’s retaliatory drones and missiles inflicting damage on GCC infrastructure, the physical disruption to supply is proving that the US security umbrella can no longer ensure the region’s safety.

Why it matters: The petrodollar is the bedrock of the USD’s status as the world’s reserve currency. GCC economies sit on roughly USD 800 bn to support their USD currency pegs, alongside sovereign wealth funds managing over USD 6 tn heavily weighted in US assets. If GCC capitals decide the US can no longer ensure their physical security, the financial architecture that relies on USD recycling channels can be jeopardized, Reuters’ Mike Dolan writes.

“The huge strategic importance of the Middle East to the USD’s role as the world’s reserve currency should not be underestimated. The current conflict may be the perfect storm for the petrodollar,” Mallika Sachdeva, strategist at Deutsche Bank Research Institute, wrote in a note (pdf).

What comes next: We are watching the acceleration of a permanent shift in global trade invoicing. If GCC wealth funds are forced to liquidate USD assets to fund domestic reconstruction, or if consumer nations rapidly transition away from globally traded maritime fossil fuels to domestic alternatives, the geopolitical premium of Middle East oil — and the USD grip on it — will permanently shrink.

The history

The decades-old arrangement was formalized in February 1945 aboard the USS Quincy, where US President Franklin D. Roosevelt and King Abdulaziz bin Saud agreed to price oil in USD and invest surpluses in USD assets, in exchange for security assurances from Washington. That agreement survived the Cold War, the 1991 Gulf War, and decades of regional instability.

BUT- The cracks have been showing for years. An Iranian drone attack in 2019 temporarily knocked out half of Saudi Aramco’s production — 5% of global crude — and the Trump administration responded with no military action.

Today’s conflict took that localized anxiety and turned it into a widespread reality. “If this war has shown anything so far, it is that allying yourself with the US no longer [ensures] security,” Jim O’Neill, former Goldman Sachs economist, said earlier this month.

The eastward shift

While the war may be a catalyst, the structural realities of the global oil trade had already shifted eastward long before the first missile was fired. The customer base for Gulf crude has changed as the US is now effectively energy independent following rapid advances in shale oil production.

Where things stand: Saudi sells four times as much oil to China as it does to the US, and a massive 85% of crude oil from the Middle East is now exported to Asia. The Kingdom has already begun a push to localize its defense industry, and is quietly experimenting with non-USD payment architecture. Add a failure of military protection to the mix, and the rationale for exclusive USD pricing is thrown into doubt.

The war could accelerate this shift

The conflict might accelerate the fragmentation of trade routes, as well as currency pricing. The inability to ensure maritime security is forcing a chaotic, bilateral approach to keeping the oil flowing. Iran is reportedly negotiating with several countries to allow tankers to safely pass through the chokepoint — but only if the oil is paid for in Chinese CNY.

ALSO- Massive capital pools are now at risk of reallocation. The GCC’s sovereign wealth funds currently manage more than USD 6 tn, largely invested in US bonds, private equity, and equities. However, the physical damage to local infrastructure, combined with the economic scarring to regional tourism, aviation, and finance, may require significant capital to repair — and the costs will keep increasing the longer the conflict continues. The GCC might need to repatriate portions of these USD savings to fund domestic recovery efforts, introducing fresh selling pressure on US Treasuries.

What’s next?

While the 1970s oil shocks drove the West to build the Strategic Petroleum Reserve and explore the North Sea, this time is entirely different. Traditional US allies — think Europe, Japan, and South Korea, the ones highly exposed to the Strait of Hormuz closure — are realizing that maritime energy supply chains are a critical vulnerability.

It’s not far-fetched to expect an accelerated policy pivot away from globally traded fossil fuels. Consumer nations can double down on subsidized renewable energy infrastructure and revive nuclear power generation programs. Heavy industry and military logistics will still require hydrocarbons for decades, but the marginal demand growth will be structurally impaired.

The gist? A world that relies on domestic renewables and nuclear power is a world with reduced energy deficits in Asia and Europe, and reduced energy surpluses in the Middle East. That is a world where the USD has less cross-border trade to intermediate.
