Gulf States Redirect Trillions Into Domestic Projects, Reshaping Global Capital Flows

Ben Powell, BlackRock’s Investment Institute strategist, told Bloomberg on September 2 that sovereign wealth funds across the Gulf Cooperation Council are redirecting capital inward at a scale that could reshape global financial markets. Rather than recycling surplus wealth into international equities, Treasury securities, and overseas real estate, Gulf states are committing that money to domestic projects.

The numbers are large. Powell put the region’s expected strategic capital expenditures at upwards of $2 trillion over the next several years, with a defining condition: the marginal dollar of new Gulf investment stays within the region. That is a sharp departure from decades of outward capital flows, and it accelerates a diversification drive that was already underway, particularly at Saudi Arabia’s Public Investment Fund. Geopolitical pressure, Powell argued, has sharpened the urgency.

The underlying logic is not complicated. If the world continues building energy independence, Gulf oil exports face structural headwinds over the long term. That reality has made domestic industrial development a priority. Powell was careful to frame the shift as acceleration, not reversal: “Oil and gas is still very important. That’s not gonna change. It’s a significant generator of cash, and that’s great. But at the margin, the urgency of deploying that cash into societal and economic diversification, which was already there, I think the urgency is even greater.”

A second dimension of Powell’s thesis ties energy, artificial intelligence, and defense into a single investment framework. Data centers demand enormous power and physical security. The Pentagon is simultaneously expanding spending on AI, microelectronics, and advanced energy systems, with its fiscal year 2027 science and technology budget request running nearly 26 percent above the prior year. The Government Accountability Office estimates that data centers could consume up to 12 percent of U.S. electricity demand by 2028. Powell’s point was that these sectors resist clean separation: “Data centers need defense. They need energy. So clearly there are distinctions, but there is an overlap. And I think it’s hard in this very complicated world to neatly parse security from the economy, from AI. They all kind of overlap.”

Geopolitical vulnerability is doing real work in this thesis. Maritime chokepoints, including the Strait of Hormuz, have long concentrated global energy flows through narrow, contestable passages. Powell described a regional turn toward self-reliance: “We can rely less, sadly, on these strategic chokepoints. We can rely less on global trading partners, so we’re gonna have to do more here at home in the region. The good news is we’ve got the funding. We’ve got the talent. We’ve got the energy to do that.” On the same day Powell spoke, Treasury Secretary Scott Bessent told the G20 that the Strait of Hormuz will become “a worthless piece of water” within two years as oil moves to land-based pipelines. Reuters has separately documented a wave of Gulf pipeline and port investments driven by regional security concerns.

Powell’s broader argument centers on a convergence of capital and state objectives. Government-led development goals, whether for traditional infrastructure like hospitals and roads or for emerging sectors like artificial intelligence, increasingly depend on capital markets for funding. As Powell put it, “We’re gonna see more partnership between government driving societal goals and capital markets, because simply put, capital markets is where the money is.”

The implications extend well beyond the Gulf. Capital that historically flowed into global markets and supported Treasury demand, equity valuations, and infrastructure financing worldwide would, under this scenario, stay home. Whether global markets can absorb a sustained reduction in Gulf inflows while Gulf economies simultaneously execute a complex diversification agenda across energy, defense, and artificial intelligence is the question Powell’s thesis leaves open.
