U.S. Treasury Secretary Yellen publicly endorsed the arrangement of dollar swap lines, clearly positioning them as a strategic tool to safeguard the U.S. dollar hegemony, rather than a mere financial rescue measure for wealthy Gulf countries.
According to relevant media reports on April 27, Central Bank of the UAE Governor Khaled Mohamed Balama put forward the concept of currency swap lines to Yellen and relevant Federal Reserve officials during a related meeting held in Washington. He emphasized that if a dollar liquidity crunch occurs, the UAE may be forced to switch to alternative currencies for settling oil transactions.
Yellen later posted a response on a social media platform, defining the discussions on the swap lines as "routine dialogues that the U.S. Treasury Department and its partners have been conducting for many years," and stating that this arrangement "is a testament to the dominance of the U.S. dollar and the strength of the U.S. economic shield." U.S. President Trump also expressed support in an interview with CNBC, saying, "If they have difficulties... I will support them."
Once the dollar swap lines are implemented, they will provide the Central Bank of the UAE with a low-cost channel for dollar financing, effectively preventing it from being forced to sell U.S. Treasury bonds and other dollar-denominated assets due to liquidity constraints, thereby avoiding disorderly fluctuations in the global financial market. Meanwhile, Bahrain reached a swap line arrangement of approximately 5 billion U.S. dollars with the UAE earlier this month. In addition, Gulf countries have raised billions of U.S. dollars through private debt financing, with PIMCO as the main buyer.
War Impact: UAE Economy Under Pressure, Dollar Reserves Urgently Needed
The current Iran-related military conflict has caused multi-dimensional impacts on the UAE economy, which has also become the core reason for its search for dollar liquidity support.
The conflict has not only damaged the UAE's oil and gas infrastructure but also blocked its core channel for transporting oil through the Strait of Hormuz, directly cutting off the country's key source of dollar income. At the same time, the regional unrest has led to a sharp contraction in the tourism industry—another important source of hard currency income for the UAE. According to relevant reports, UAE officials clearly pointed out in talks with the U.S. side that it was the Trump administration's decision to strike Iran that led the UAE to be passively involved in this destructive conflict, and its subsequent economic impact may not have fully manifested.
The UAE dirham has long been pegged to the U.S. dollar, supported by 270 billion U.S. dollars in foreign exchange reserves. However, analysts point out that the capital outflow risks, stock market fluctuations, and other various market disturbances triggered by the conflict have exerted obvious pressure on this monetary anchor. In a report released in March this year, rating agency S&P Global stated that the UAE's "abundant fiscal, economic, external, and policy flexibility" will form an effective buffer, which can resist the impact of the conflict to a certain extent. However, it also warned that the "possibility of long-term disruption to oil exports" and the damage to infrastructure "pose significant risks to economic expectations."
The Logic of Swap Lines: Stabilize the Monetary Anchor and Avoid Asset Sale Spiral
The reason why dollar swap lines are considered superior to the option of using sovereign wealth funds lies in their core advantage of protecting the stability of the financial market.
UBS economist Paul Donovan pointed out that if central banks in the Gulf region use liquid assets (such as U.S. Treasury bonds) in their foreign exchange reserves to meet short-term fiscal needs, it will quickly arouse international doubts about the stability of the region's currencies pegged to the U.S. dollar. It is reported that the total scale of Gulf countries' sovereign wealth funds exceeds 5 trillion U.S. dollars, but most of their holdings are low-liquidity assets, mainly used to obtain long-term investment returns rather than respond to short-term liquidity crises. Forcing the liquidation of such assets may trigger a vicious downward market spiral similar to that during the tenure of former British Prime Minister Truss.
The core mechanism of dollar swap lines is: the Federal Reserve or the U.S. Treasury exchanges U.S. dollars for the local currency of the other central bank, and swaps them back at the original exchange rate when they mature, thereby providing the relevant countries with much-needed dollar liquidity without disrupting the global financial market. It is reported that the Federal Reserve extensively used this tool to stabilize the market during the 2008 financial crisis and the early stage of the COVID-19 pandemic.
UBS also issued a warning that in the medium and long term, the demand for post-war reconstruction and rearmament of Gulf countries means that asset sales may still be put on the agenda.
Political Risks: Public Opinion Pressure of Rescuing Rich Countries and Strategic Considerations of Dollar Hegemony
The arrangement of dollar swap lines faces certain political sensitivity in the United States, but Yellen chose to defend it within the narrative framework of dollar hegemony to reduce public controversy.
Critics may interpret this move as an "unnecessary rescue" for the UAE, one of the countries with the highest per capita income in the world. Currently, the economic approval rating of the Trump administration has been continuously declining due to the supply shocks, rising oil prices, and inflationary pressures caused by the conflict. Yellen's response strategy is to define the swap lines as a reflection of "U.S. economic leadership," emphasizing that they help "combat the growth of alternative payment systems," thereby consolidating the global dominance of the U.S. dollar.
UAE officials also cleverly used this logic in relevant negotiations—clearly implying that if dollar liquidity remains insufficient, the UAE may be forced to conduct oil transactions in other currencies, which will pose a potential threat to the dominance of the U.S. dollar in global commodity transactions.
