Original research snapshot · 28 October 2026, 11:32 HKT · before that day’s Fed decision. Retained analysis, not refreshed market data.
Rates and the inflation constraint
The financing backdrop has become less forgiving. The Fed raised its target range to 3.75–4.00% on September 16. September CPI then rose 0.6% on the month and 3.7% over the year, with gasoline accounting for more than half the monthly increase. The October 28 Fed decision is still ahead at this note’s research cut-off. I would not build an infrastructure thesis around imminent rate relief when the inflation data leave that assumption open to challenge. [7][8][9]
Iran and the oil channel
Iran and the wider regional conflict matter through that inflation channel, not just through the price of diesel for generators. On October 6, the EIA raised its fourth-quarter Brent forecast to $105 a barrel, $14 above its previous forecast. On October 28, Reuters reported Brent around $115 after the Houthis claimed an attack on a Saudi refinery; Saudi confirmation was still absent from that report. The forecast and the intraday price are different observations, but both make an easy-energy assumption harder to defend. [10][11]
It would be too crude to translate higher oil directly into higher costs for every American data centre. Petroleum supplied less than 1% of US electricity in 2025. The broader risk is pressure on household spending, transport costs and inflation expectations, potentially keeping financing expensive. An AI project can face a higher required return even if its own electricity contract has not changed. [12]
The same pressure reaches Asia
Growth and renewed financial pressure can coexist. Writing from Sri Lanka, that distinction is worth keeping in view: the IMF’s September assessment put second-quarter growth at 4.2%, while reporting August inflation of 8% following the global oil shock. Hong Kong offers another reminder. The HKMA raised its Base Rate to 4.25% after the Fed’s September move, although its HIBOR-based calculation was materially lower. Neither a strong growth story nor the currency peg makes local funding conditions uniform. [13][14]
The midterms and who pays for the grid
The US midterms are also becoming a debate about who pays for the buildout. On September 30, a Senate procedural vote on the Ratepayer Protection Act fell short at 57–43. The proposal concerned recovery of the incremental grid-upgrade costs serving large users. Ahead of the November 3 election, the investment issue is not simply which party likes AI. It is whether power tariffs, permits and cost allocation change the economics or timing of a particular site. [15][16]
Making developers cover more infrastructure costs could reduce project returns and still improve the chances of getting projects approved. A smaller return on a project that gets built may be preferable to a larger projected return on one that stays blocked. The cost and the approval benefit need to be assessed together.
A friendlier Fed would not automatically solve a borrower’s funding problem. Treasury yields and credit spreads are different parts of the bill. A rate cut offers limited relief if lenders simultaneously demand a much bigger premium to finance the company. The customer can be right about demand and still struggle with the cost of reaching it.
