After signing a US$142 billion (£107 billion) arms deal with Saudi Arabia, Donald Trump mentioned the US bond with that nation was “more powerful than ever”. He was additionally reportedly fairly happy with the gift of a private jet from Qatar.
However these preparations are simply the newest developments in a protracted historical past of the Gulf monarchies supporting the structure of American international energy. And whereas the six Gulf states (Saudi Arabia, United Arab Emirates, Kuwait, Qatar, Bahrain and Oman) have lately began redirecting their vitality and commerce ties eastward, particularly in direction of China, they continue to be deeply embedded within the US-led monetary order.
As I discover in my current e-book, Crude Capitalism, the Gulf states had been instrumental within the rise of American international financial dominance.
With oil rising because the dominant fossil gas by way of the second half of the twentieth century, the Gulf’s nationalised petroleum industries generated huge quantities of earnings. A lot of this was invested again into the US monetary markets, significantly treasury bonds (basically a long-term mortgage to the US authorities). This gave the US entry to low-cost international capital and strengthened the worldwide dominance of the greenback.
Put merely, the Gulf states weren’t peripheral to the US’s rising monetary energy – they had been an important contributor.

This association additionally concerned a political discount: US army safety for the Gulf monarchies in alternate for funding flows and vitality stability. The end result was an online of US army bases throughout the area and a deep alignment between authoritarian Gulf regimes and western strategic pursuits.
However a lot has modified previously 20 years. China’s rise as a worldwide manufacturing hub has pushed an enormous enhance in oil consumption, shifting the path of the Gulf’s oil exports away from the US and western Europe in direction of China and east Asia.
These vitality ties have been accompanied by a lot deeper commerce interdependence and an enormous enhance in Chinese language investments within the Gulf. In 2005, China was responsible for simply 9% of the Gulf’s imports. At this time, that determine is over 20%, whereas the US and EU’s share has fallen from 45% to 16%. China has additionally recently overtaken the US as the most important international investor in Saudi Arabia.
From Beijing’s perspective, the Gulf is a vital vitality lifeline. From the Gulf’s aspect, China’s persevering with demand for oil, gasoline and petrochemicals is a crucial a part of its financial future.
For the second, that financial scenario seems fairly sturdy. In 2024, Gulf nations held round US$800 billion in international reserves (foreign exchange and different property), which is greater than India or Switzerland. Their sovereign wealth funds (a state owned funding fund) manage one other US$4.9 trillion of property.
Personal wealth, together with that held by ruling households, stood at US$2.8 trillion in 2022, and is predicted to achieve US$3.5 trillion by 2027.
A lot of this cash is invested domestically, in sectors together with infrastructure, actual property and renewable vitality. However an astonishing quantity flows straight into US markets.
Oil be again
In accordance with US Treasury data, complete Gulf holdings of American securities (bonds, shares and company debt) rose from US$611 billion in 2017 to over US$1 trillion in 2024. Outdoors of Canada and monetary hubs like London and Eire, the Gulf is now the most important international investor within the US inventory market.
One other route by way of which Gulf wealth flows again into the US is through army procurement. In accordance with the Stockholm International Peace Research Institute, the Gulf states accounted for 22% of all international arms imports between 2019 and 2023 – greater than some other area on this planet.

The US provides the overwhelming majority of those weapons. On this manner, Gulf spending helps the American army trade, and in return, these states change into extra intently tied to the US army’s umbrella.
These deep army, monetary and strategic ties assist clarify the actual focus of Trump’s go to to the Gulf. A lot of the dialogue could have centred on large funding pledges made by Gulf states to the US – together with Saudi Arabia’s promise to take a position as much as US$600 billion, and the UAE’s commitment to a US$1.4 trillion funding over ten years.
And such pledges replicate a broader agenda which includes increasing offers in synthetic intelligence, critical minerals, vitality infrastructure and superior manufacturing.
So Trump travelling to the area is not only about personal jets and spectacle. It’s concerning the persevering with relevance of a structural relationship important to American energy, and a deepening monetary integration between the Gulf and the US.
For even because the Gulf reorients its vitality flows eastward, it stays deeply tied to US finance, the US army trade and US property. In an period of weakening US international energy – and the doable spectre of a deeper conflict with China – that is what is going to outline Trump’s go to.
