2026's rate trajectory is a fiscal dominance story. The Fed's primary inflation-fighting tool now conflicts with the cost of servicing $36 trillion in outstanding debt. That conflict predates the Iran war by years.

Markets started 2026 pricing four Fed rate cuts. They now price zero, with futures pricing a hike by January 2027. Three months of data explain why.

Iran drove Brent above $115 per barrel at its peak. With the ceasefire fragile, Brent holds around $95 and European gas storage remains depleted.

The five largest hyperscalers are on track to spend over $675 billion on AI infrastructure in 2026, up more than 60% on last year. The IEA reported data centre electricity demand surged 17% in 2025, outpacing global electricity demand growth of 3%. Torsten Slok, Chief Economist at Apollo Global Management, told Bloomberg Surveillance on Monday that the AI build-out will be inflationary in its early phase, preventing Warsh from cutting rates as quickly as he has indicated.

The One Big Beautiful Bill added 0.9% of US GDP to the 2026 federal deficit. The CBO projects that deficit at $1.9 trillion this year, growing to $3.1 trillion by 2036.

This is what separates 2026 from 2022. Former Treasury Secretary Janet Yellen defined the mechanism at Brookings on January 4: fiscal dominance, the condition where debt has grown so large that the central bank cannot raise rates as high as inflation warrants without compounding the fiscal burden. Today, every sustained 100 basis points of higher rates adds materially to annual debt service costs. Gita Gopinath, Harvard economist and former IMF First Deputy Managing Director, told Bloomberg's Odd Lots on May 29 that the same structural forces are driving rates higher across Japan, Korea, and the UK. Kevin Warsh, confirmed as Federal Reserve Chair in May 2026 and known for favouring lower rates, inherits that constraint.

The Fed's March 2026 projections revised PCE and core PCE inflation to 2.7% each for this year. Core inflation has run above the 2% target for five consecutive years. The ECB's May 2026 Financial Stability Review stated that downside risks related to geopolitical, fiscal and macro-financial developments appear underestimated.

This is macro blindness: markets have absorbed the 4-to-0 cuts repricing as a geopolitical response, without pricing the structural constraint that persists once the conflict passes.

The near-term picture is clear. Ceasefire negotiations remain fragile, AI infrastructure spend is accelerating, and fiscal stimulus is front-loaded into this year.

The structural question is harder and more consequential. If the neutral rate has reset above what a decade of models assumed, the repricing is not behind us.

For investors, bankers, and corporates still operating on the January rate path: at what point does planning for normalisation become the riskier assumption?
