The AI buildout needs more than chips. Data centers also require power, grid connections and telecommunications infrastructure, putting technology companies and governments in competition for financing. Central bankers at the October 2026 IMF–World Bank meetings in Bangkok said that investment demand could add to borrowing costs and make a period of higher interest rates more likely—even before AI’s productivity gains are fully realized. 17
That is a risk to watch, not a prediction that rates must rise or that the AI boom will collapse. Policymakers are confronting a demand shock while financial markets remain exposed to high debt, rising yields and the possibility that AI-related earnings disappoint. 6

Why AI investment can make capital more expensive
Building AI infrastructure requires large, overlapping investments in computing, data centers, electricity and networks. When companies and governments seek funding at the same time, they compete for investors’ money. The result can be higher borrowing costs and less room in government budgets for other priorities. 17
The timing matters. Spending and demand for financing can rise before new infrastructure is operating and generating productivity gains. That creates a potential period in which investment adds economic momentum and inflationary pressure, while the eventual boost to supply remains uncertain. 17

This is a different emphasis from the post-2008 concern that weak demand and abundant savings could hold back growth and inflation: the current worry is that competing investment needs may make capital scarce. The neutral interest rate, or R-star—the rate consistent with an economy in balance—could rise if demand for capital stays strong. But estimates remain uncertain; the available reporting does not establish how far R-star might move or for how long. 17

Higher financing demand does not mean automatic rate hikes
A distinction matters: central bankers can see the possibility of persistently higher financing costs without committing to an immediate increase in their policy rates.
At the meetings, Federal Reserve Chair Kevin Warsh called AI an economic shock and reaffirmed his commitment to price stability, but did not signal urgency for an October rate increase. 2 Bank of England Chief Economist Huw Pill, meanwhile, questioned market expectations for four rate increases over the following year.
28 Those comments point to uncertainty about the pace of policy, not a settled path of hikes.
Christine Lagarde has also argued for a measured response to inflation, saying that dangerous second-round effects had not yet emerged. 18 Later, she said higher bond yields were already tightening financing conditions, restraining growth and ultimately reducing inflationary pressure.
20 In other words, markets can tighten financial conditions even when central banks do not immediately raise policy rates.
AI borrowing adds pressure to an already strained bond market
The IMF has warned that markets’ resilience should not be mistaken for safety, pointing to risks including an AI-related selloff and rising government bond yields. 4
6 The concern is that companies funding infrastructure and governments issuing debt may compete for many of the same investors.
One reported measure of the shift: hyperscalers’ share of global investment-grade bond issuance rose from less than 1% in 2024 to 10%. 13 That figure signals a larger financing presence, but it does not by itself show that corporate borrowing is displacing government debt or that a disorderly market move is inevitable. The IMF’s reported warning is about the potential for overlapping pressures—including public debt, inflation and AI borrowing—to make bond markets more vulnerable.

France illustrates the pressure from higher yields. Its 10-year bond yield was reported near 5% in early October, its highest level since 2002. 19 Lagarde said the subsequent global bond selloff had raised financing costs, with debt-laden France among the hardest hit.
20 Higher refinancing costs can narrow governments’ fiscal room, particularly when public debt is already a concern.

Infrastructure and earnings are the test of the boom
The financial risk depends in part on whether expected profits justify the scale of investment. The IMF has warned that weaker or less durable AI investment and profits could trigger a correction in AI-related stocks and debt. 8 That is a potential chain of events, not evidence that a crisis is underway.
Physical constraints offer another test. Reuters reported that Oracle issued a force-majeure notice over possible power-supply delays for an AI data center in New Mexico, which could postpone the project by up to a year. 46 Separately, AI-related debt issuance fell to $23 billion in September, nearly half the previous month’s level, according to data attributed to Morgan Stanley. That single-month decline is a sign of changing financing conditions, but does not establish that the broader investment boom has ended.
48
The central takeaway is that AI’s capital needs may keep borrowing costs and bond-market risks in focus while productivity gains remain uncertain. Whether that produces persistently higher rates or a deeper market correction is still an open question—not a foregone conclusion. 17
