Citadel: High Treasury Yields Driven by Strong Economy and AI Capital Competition
nashnova research
Citadel Securities argues that U.S. Treasury yields at multi-decade highs are driven not by worsening inflation fears but by persistent economic strength and competition for capital from AI investment and fiscal deficits — a fundamental shift in what anchors rates.
Why are yields rising? Not inflation — growth is too strong
In September, nearly all of the rise in U.S. 10-year Treasury yields came from real yields, while inflation expectations stayed stable.
This means → investors are not pricing in runaway prices; they are reassessing how strong and how durable U.S. growth really is, and demanding higher inflation-adjusted returns.
In plain terms = the market isn't scared of money losing value — it thinks the economy is so hot that too many borrowers are competing for the same pool of capital.
Who is competing for capital? Three forces at once
Fiscal spending: the U.S. government runs persistent high deficits, borrowing heavily.
AI investment: tech firms see higher potential returns and keep expanding AI infrastructure spending.
Loose financial conditions: further fuel private-sector demand for funds.
This means → the public and private sectors are bidding for capital simultaneously. The market either needs more savings flowing in, or must offer higher real yields to attract them.
Have yields peaked? Citadel says don't rush to call it
Citadel's head of EMEA fixed-income sales, Nohshad Shah, says he is unwilling to call a yield peak just because inflation is cooling.
His logic: the yield driver has shifted from inflation to growth and capital competition — inflation is down, but growth persists, deficits persist, and AI keeps burning cash.
For yields to rise materially further, there would need to be fresh repricing in growth expectations, the policy outlook, or term premium (the extra return investors demand for holding long-dated bonds).
Are rate-hike expectations reasonable? Four cuts may not be enough
Markets currently price in about four Fed rate hikes over the next 12 months; Shah calls this "reasonable."
This reflects sticky inflation and resilient U.S. demand.
Shah's deeper concern: fiscal support and AI investment may make parts of demand insensitive to interest rates — no matter how expensive money gets, strategic spending continues.
In plain terms = high rates are supposed to brake the economy, but fiscal policy and AI act like two accelerator pedals, offsetting the brake.
Could high rates undermine the AI boom itself?
Shah estimates that roughly one-third of big cloud companies' capex this year is debt-financed.
This means → the higher real rates go, the heavier AI projects' financing costs become, and the more future cash flows must deliver.
Shah therefore favors Microsoft and Alphabet (Google's parent) — broader businesses and more monetization channels give them a stronger cushion as borrowing costs rise.
His core judgment: the AI boom can support a higher cost of capital, but "it cannot make that cost irrelevant" — companies must ultimately prove their spending generates adequate returns.
