AI Is Moving From Productivity Story to Cost-of-capital Story

Three central banks, one AI shock, three different outcomes — the next monetary regime hinges on where AI enters the economy and what it becomes once inside.

Multi-decadehighs in long-term yields (ECB)

“Same technology. Different entry channels. Different rates.”

The evidence is converging. The ECB reports that long-term yields rose to multi-decade highs while corporate debt issuance to finance AI investment surged, particularly in the U.S. The Bank of England says the policy risk begins when external energy and technology shocks feed into wages, pricing and inflation expectations. The SNB kept rates at 0%, with inflation still contained because domestic second-round effects remain limited.

The key question is now: where does the AI shock enter the economy — and what does it become once inside?

The Great Split: Three Monetary Channels

Same technology, different outcomes

U.S. — Capital Formation

AI enters through capital formation and financing demand. Result: greater exposure to higher market rates.

UK — Imported Costs

AI-energy pressure enters through imported costs and stronger second-round effects. Result: inflation persistence and tightening risk.

Switzerland — Weak Pass-Through

The same external shock generates weaker domestic effects. Result: contained inflation and policy hold.

The Investor Action Hierarchy

Positioning through the split

  1. Stay shorter while AI financing demand, sovereign issuance and term premia remain elevated. signal: Duration is the first line of exposure.

  2. Favor power, grids, compute and infrastructure where AI CapEx is already creating demand. signal: Own where the spending lands first.

  3. Prefer companies turning AI into productivity, margins and cash flow — not simply spending more. signal: Cash flow over CapEx.

  4. Be selective in data centres, power projects, private credit and leveraged suppliers exposed to refinancing. signal: Refinancing risk is the hidden fault line.

  5. Extend duration and broaden into downstream AI adopters when measurable productivity begins lowering unit costs. signal: Productivity is the signal to rotate.

Key takeaways

The Velocity Insight

  • The central-bank question is no longer "Is AI inflationary or deflationary?" but where does AI enter the economy — and what does it become?
  • In the U.S., it becomes financing demand; in the UK, second-round inflation; in Switzerland, contained imported pressure.
  • That is the Great Split — same technology, different entry channels, different rates.
  • The next monetary regime depends on how quickly AI investment becomes productivity — and how much financing and inflation pressure accumulates before it does.
