Iran War Shatters Global Reserve Order

The virtuous cycle that has defined global finance for half a century—where the United States ensured Middle Eastern stability in exchange for oil revenues being recycled into Washington’s debt—has officially fractured. This arrangement, famously brokered in 1974, allowed the US dollar to reign supreme as the world’s reserve currency while subsidising American borrowing costs. However, the current conflict between the US, Israel, and Iran has broken the loop at both ends, fundamentally altering the calculus for central banks and private investors across the globe.

The Great Treasury Sell-Off
Since the initiation of military strikes on 28 February, a historic shift has occurred in the bond markets. Foreign central banks have transitioned into aggressive net sellers of US Treasuries for five consecutive weeks. Data from the Federal Reserve Bank of New York indicates that holdings have plummeted by approximately 82 billion US dollars, reaching their lowest levels since 2012.

In a departure from traditional crisis behaviour, where capital typically flees to the safety of US government debt, the 10-year Treasury yield has climbed from 3.9 per cent to above 4.4 per cent. The reason is rooted in a "belligerent" shift: the "flight-to-quality" trade historically relied on the premise that the United States acted as a bystander or stabiliser in global conflicts. With the US now a direct combatant, investors are treating Treasuries as a source of risk rather than a refuge. This has forced major oil-importing nations, including India and Thailand, to liquidate their bond holdings to defend their own currencies against the surge of oil prices exceeding 100 US dollars per barrel.

The GCC Model and the Hormuz Chokepoint
On the exporting side, the petrodollar mechanism has effectively seized up. In a standard oil shock, rising prices usually result in windfall profits for Gulf producers, which are then reinvested into US assets. This time, the effective closure of the Strait of Hormuz has stranded those very barrels. Total production across Kuwait, Saudi Arabia, the UAE, and Iraq was slashed by at least 10 million barrels a day in March.

While alternative pipelines exist, they handle only a fraction of the normal throughput and remain under active threat from drone strikes. Qatar’s declaration of force majeure on liquefied natural gas (LNG) exports further complicates the regional outlook. Consequently, Gulf sovereign wealth funds are no longer parking surpluses in Washington; instead, they are reviewing existing investment pledges and spending heavily on domestic air defence. The circular flow of dollars has stopped, leaving the US Treasury market without its most reliable buyers.

A Historic Pivot to Gold
The long-term structural implications of this break are staggering. The share of US Treasuries held by foreign investors has dwindled to roughly 32 per cent, down from nearly half in the early 2010s. Most significantly, for the first time since 1996, global central banks now hold more gold in aggregate than US government bonds. This is no longer market "noise"; it is a clear signal that the world is moving toward a post-dollar reality.

For those of us in the ASEAN region, this "de-dollarisation" accelerates the need for radical diversification. While there is still no single market that offers the same depth as US debt, the distinction between "no realistic alternative" and an "unquestioned safe haven" has never been clearer. Kissinger’s 1974 deal survived the Cold War and a global pandemic, but it has not survived the tactical shifts of 2026. As the political foundation of the petrodollar crumbles, the financial structures that rested upon it are following suit, ushering in a new era of commodity-backed reserves and regional autonomy.
