The ongoing conflict between the United States and Iran could make it harder for three Gulf countries — Saudi Arabia, Qatar and the United Arab Emirates — to deliver on nearly $4 trillion in economic commitments to the US announced under President Donald Trump’s “America First” agenda, according to a new analysis from the Peterson Institute for International Economics (PIIE). The 15-page report released Monday says the Gulf states are facing growing economic pressure from the US and Israel’s war on Iran, including the need to spend more on defence, energy infrastructure and trade. It has also weakened their confidence in the US security umbrella in the Gulf,” the report said.
The war has hit the Gulf economies much harder than the global economy at large, according to the report. The International Monetary Fund (IMF) cut its 2026 global growth forecast by 0.3 percentage points, but the reductions were much larger for the Gulf states. The IMF cut Qatar’s growth forecast by 14.7 percentage points, to 8.6 percent.
Saudi Arabia’s forecast was cut from 4.5 percent to 1.7 percent, while the UAE’s was reduced from 5.6 percent to 1.7 percent, as well. Gulf governments have enough financial assets and borrowing capacity to avoid an immediate funding crisis, according to the report, but PIIE said the economic pressure could lead the countries to prioritise spending at home over investments in the US. Saudi Arabia’s Public Investment Fund has reduced the share of its portfolio allocated to international investments by 10 percent over the last six years to 20 percent, down from 30 percent in 2020.
The report also warns that delays in fulfilling the investment commitments could lead to additional pressure from the White House, which has previously used tariffs to push other countries to follow through on their commitments. In January 2026, Trump threatened to raise tariffs on South Korean goods, citing delays by the Korean legislature in enacting its US investment agreement,” the report said. That pressure has coincided with progress on US investment commitments from South Korea.
The Wall Street Journal reported last week that the South Korean government is close to a potential energy investment deal worth more than $100bn that would help support the expansion of artificial intelligence infrastructure in the United States. Qatar, meanwhile, continues to pursue investments in the US energy sector. QatarEnergy began producing liquefied natural gas (LNG) at a facility in Texas in March and began exports the following month.
QatarEnergy’s ties with US energy companies could expand further. It is negotiating with several US LNG producers on contracts through 2031 to help replace capacity lost after Iranian attacks damaged Qatar’s LNG facilities, according to the news agency. The PIIE report said the lack of clear definitions, timelines and ways to measure the investment commitments could make it difficult to determine whether the countries are actually following through.
