Challenging Dollar Supremacy: Is the UAE Rethinking the Dollar Order?

For more than five decades, the petrodollar system has served as one of the central structural pillars of American financial supremacy. Since its establishment in the 1970s, the system has anchored the United States’ monetary power by ensuring that Gulf oil exports remain overwhelmingly denominated in United States dollars. Under this arrangement, Gulf producing nations receive American security guarantees in exchange for recycling their oil revenues into US Treasury securities and dollar-denominated financial markets—a self-reinforcing cycle that has entrenched the dollar’s status as the world’s foremost reserve currency and systematically reduced American sovereign borrowing costs for decades.

The United Arab Emirates has, historically, been among the most faithful participants in this arrangement. Its national currency, the dirham, remains pegged to the USD, and its extensive sovereign wealth funds are invested predominantly in dollar-denominated assets. Nevertheless, a convergence of recent developments—an armed conflict in Iran, severe disruptions to Gulf oil exports, and an acute domestic dollar liquidity constraint—has placed the UAE at an unprecedented geopolitical and financial crossroads.

The catalyst for the UAE’s monetary anxieties has been the ongoing US-Israel-Iran War. The Iranian retaliatory campaign inflicted material damage upon Gulf energy infrastructure and severely disrupted tanker movements through the Strait of Hormuz. Given that the Strait facilitates the transit of approximately one-fifth of all globally traded petroleum, even a temporary interruption carries profound consequences for export revenues, foreign currency reserves, and domestic dollar liquidity.

The UAE, which produces approximately 3.4 million barrels of crude oil per day, has experienced a significant compression of its dollar-denominated revenue streams as a consequence of reduced export throughput. A reduction of even 20% to 30% in export volumes would represent a multi-billion-dollar monthly shortfall for Abu Dhabi’s sovereign accounts. While the UAE retains approximately USD 270 billion in foreign-exchange reserves and commands trillions of additional dollars across its sovereign wealth funds—thereby precluding any immediate liquidity crisis—the wartime disruption has nonetheless exposed a critical structural vulnerability: the country’s dollar inflows, ordinarily robust and self-sustaining, have been materially curtailed by a regional conflict in which the UAE played no initiating role.

A March 2026 assessment by S&P Global acknowledged the UAE’s considerable fiscal buffers while simultaneously warning that “prolonged disruption to oil exports and infrastructure damage” posed clear risk to its sovereign outlook—a characterisation that underscores the gravity of the present juncture.

Antecedent to the Iranian crisis, the UAE had been engaged in the methodical expansion of its network of local-currency financial arrangements—a strategy that warrants examination in the present context. The most recent and consequential such development is the landmark bilateral currency swap agreement concluded with the Kingdom of Bahrain.

The Central Banks of the UAE and Bahrain formalised a Dh20 billion (BHD 2 billion, equivalent to approximately USD 5.5 billion) currency swap agreement, executed on a five-year renewable basis, with the stated objectives of strengthening financial cooperation, facilitating cross-border trade settlement in local currencies, and enhancing regional monetary stability. The agreement was signed by Khaled Mohamed Balama, Governor of the Central Bank of the UAE, and Khalid Humaidan, Governor of the Central Bank of Bahrain.

In practical operational terms, the arrangement enables Bahraini financial institutions requiring UAE dirhams to access them directly from the Central Bank of the UAE, thereby circumventing reliance upon volatile international market funding mechanisms. Governor Balama characterised the agreement as reflective of a “shared commitment to expanding monetary cooperation and strengthening bilateral trade and investment ties,” whilst Governor Humaidan described the swap line as a milestone in the longstanding relationship between the two nations, underscoring its contribution to regional financial integration.

This agreement does not exist in isolation. In October 2025, the Central Bank of the UAE and the Central Bank of Turkey concluded a USD 4.9 billion bilateral currency swap arrangement—a further indication that Abu Dhabi has been systematically constructing a portfolio of non-dollar monetary instruments. Analysts have observed that bilateral currency swap lines are increasingly deployed as strategic instruments of central bank policy, particularly as sovereign institutions seek to reduce exposure to exchange-rate volatility and to enhance resilience against systemic global financial shocks. At the commercial level, such arrangements progressively reduce transaction costs for businesses by diminishing dependence upon the US dollar as an intermediary settlement currency.

Against the backdrop of this quiet but deliberate de-dollarisation at the margins, the UAE has simultaneously advanced a firmly dollar-centric request to Washington. During high-level meetings convened in the United States capital, Central Bank Governor Balama formally raised the prospect of establishing a currency swap line between the UAE and the United States with Treasury Secretary Scott Bessent and senior Federal Reserve officials.

The American response was broadly accommodating. National Economic Council Director Kevin Hassett publicly affirmed that “the UAE has been an incredibly valuable ally throughout this effort,” and stated that the administration would make every effort to provide assistance should it prove necessary. President Trump subsequently confirmed that the establishment of a currency swap line with the UAE is under active consideration. Secretary Bessent further noted that numerous Gulf and Asian allied governments have similarly requested access to dollar swap facilities, suggesting that the UAE’s approach reflects a broader pattern of concern among Washington’s partners regarding dollar liquidity in the context of the Iran conflict.

At first analytical consideration, the UAE’s appeal to Washington appears to constitute an unambiguous reaffirmation of its profound dependence upon the dollar system. In a narrow technical sense, this interpretation is accurate: the UAE is, in essence, requesting deeper integration into the Federal Reserve’s dollar liquidity infrastructure. However, a comprehensive analysis of the full diplomatic context reveals a considerably more complex strategic posture.

The UAE’s request for a dollar swap facility was not advanced in isolation. It was accompanied by what informed observers have characterised as a calibrated diplomatic warning. According to officials present during the Washington meetings, Governor Balama cautioned that sustained dollar liquidity constraints could ultimately compel Abu Dhabi to pursue alternative currency arrangements for oil transaction settlement, explicitly identifying the Chinese renminbi as a prospective substitute if the availability of dollars were to deteriorate further.

This warning carries considerably greater strategic weight than Gulf posturing in prior years, for several reasons. First, the blockade of the Strait of Hormuz has materially constrained UAE crude export revenues, creating a genuine, rather than merely theoretical, dollar shortfall. Second, the requisite financial infrastructure for yuan-denominated oil settlement already exists. The UAE participates in Project mBridge, a cross-border central bank digital currency settlement platform, Chinese state financial institutions maintain an established presence in Abu Dhabi, and the China International Payments System (CIPS) provides the transactional rails for yuan settlement. A decision to price oil in renminbi would therefore require a political determination rather than the construction of new financial infrastructure. Third, China is currently the UAE’s largest crude oil customer by volume, with approximately 35% of UAE crude exports directed to Chinese buyers in 2025. Were those shipments to be denominated in renminbi, the consequences would constitute a structural realignment of petrodollar flows with implications for global financial markets.

Strategists at Deutsche Bank have cautioned that the US-Israel-Iran War risks exacerbating pre-existing fractures in the petrodollar regime, noting that “damage to Gulf economies could encourage an unwind in their foreign asset savings,” and that “the conflict could be remembered as a key catalyst for erosion in petrodollar dominance, and the beginnings of the petroyuan.” The Bank further highlighted reports that passage through the Strait of Hormuz may be conditionally available to vessels transporting oil priced in renminbi—a development it assessed as warranting close observation.

UAE officials also advanced a pointed political argument in the course of their Washington discussions: that the United States, having initiated the armed campaign against Iran, bears responsibility for the economic consequences inflicted upon allied states that were neither party to the decision nor insulated from its financial repercussions.

What renders the UAE’s current position of particular analytical interest is that its request for a United States dollar swap line and its implicit threat of a renminbi pivot are not contradictory in strategic terms. Rather, they constitute two complementary instruments of the same sophisticated diplomatic negotiation. The swap line request functions, in essence, as a transaction proposal: in exchange for access to US dollar liquidity infrastructure, the UAE will have no operational necessity to price oil in alternative currencies. The American response to this proposal will determine the subsequent trajectory of events. Extending a swap line imposes relatively modest costs upon the United States whilst securing continued UAE adherence to the petrodollar framework; declining to do so creates the precise conditions under which a partial renminbi transition becomes operationally rational.

The UAE is, therefore, not confronted with a binary choice between the dollar and the yuan. Rather, it is deploying the credible prospect of a renminbi pivot as leverage to extract dollar support from Washington—a demonstration of financial statecraft that simultaneously reveals both the depth of the UAE’s structural embeddedness in the dollar system and the increasing operational credibility of the alternative.

This episode additionally illuminates a broader structural truth regarding the petrodollar’s foundations. The system’s durability has never rested upon economic logic alone. It has been sustained, in equal measure, by the confidence of Gulf producing nations that the United States constitutes a reliable guarantor of regional security and economic stability. If Gulf partners arrive at the assessment that American engagement generates instability rather than security, the consequent erosion of confidence may prove more damaging to dollar hegemony than any bilateral currency arrangement. As one analysis noted, whether or not Abu Dhabi ultimately secures a swap line, “other Gulf governments will closely study how Washington responds during this test,” and their conclusions may shape oil pricing, reserve allocation, and strategic alignment across the Middle East for years to come.

The recent convergence of the UAE–Bahrain currency swap agreement, the formal request for a United States dollar swap line, and the explicit warning regarding potential renminbi-denominated oil sales constitutes, in aggregate, a coherent and strategically sophisticated statement of intent. The UAE has not abandoned the dollar system, nor is it seeking to do so in the near term. However, it has made unambiguously clear that its continued adherence to the petrodollar framework is neither unconditional nor irrevocable.

The UAE’s position reflects a broader transformation occurring across the Gulf region: producing nations are increasingly treating their alignment with the dollar system as a negotiated relationship subject to reciprocal obligations, rather than an immutable structural fact. The petrodollar arrangement, established through the Kissinger-Faisal framework of the 1970s, was predicated upon an implicit exchange: dollar denomination of oil exports in return for American security guarantees. The current crisis has placed that exchange under direct examination.

Whether Washington responds with a willingness to preserve Gulf confidence in the reliability of that exchange will determine not only the immediate trajectory of UAE-US financial relations, but may well shape the long-term architecture of the global monetary order.
