Forward 2026 scenario · modelled, not forecast
What is fiscal dominance, and why should a tech holder care?
It is the regime where a government’s debt load is so large that monetary policy stops being free to fight inflation. The central bank wants to hold rates high; the cost of servicing the debt says it cannot. Price stability becomes the variable that gets sacrificed.
For you this is not abstract. Your concentrated equity is a long-duration asset — its value is mostly future cash flows discounted back. The discount rate is the one input fiscal dominance pushes the wrong way. It is one node in a wider failure map: read it alongside the sovereign read on the United States and the scenario where a Treasury auction strains the banking system.
The cost to a concentrated book
What does it cost when rates stay higher for longer?
It costs duration first, and your book is nearly all duration. US federal debt is near 128% of GDP in 2026, with net interest already at roughly $1.0 trillion for the fiscal year (CBO Budget Outlook, January 2026). With CPI back to 4.2% in May 2026 and the 10-year Treasury at ~4.49% as of 17 June (CNBC; Federal Reserve H.15), the Fed is signalling hikes, not cuts. Every basis point of “higher-for-longer” compresses long-duration tech valuations the most — exactly the position holding 60–90% of your net worth. The structural defence is convexity that pays into the same shock; the tail-risk hedging logic sets out how a small, persistent cost buys a large payout when the regime arrives.
What does engineered resilience look like here?
A known repricing surface. You stop guessing how a 100bp shift in real yields hits your single ticker and start reading it — the duration drag, the regime where it triggers, the hedge carried before the auction wobbles.
How it works
The Sandbox Engine
Compiles 50,000 macro paths against your allocation — including a fiscal-dominance regime: rising long yields, sticky inflation, a Fed that holds. You edit the inputs and watch your distribution move.
diffusion sampling · fat-tailed real-yield shocks · published 4.2% false-comfort rate
The engine samples tails nonparametrically rather than assuming Gaussian thinness, and it prints the share of runs that understate realized loss. Cleon Peterson’s Blood & Soil paints the mechanism in one image: anonymous power overriding restraint — the state’s debt need overriding price stability, which is what reprices your book.
The objection
“Isn’t an inflation scenario just guessing the macro?”
No — it is the opposite of a forecast. This is a modelled stress path, not a prediction that rates rise. You run the regime to see your exposure under it, audit the equations, and export the paths. The point is the failure surface, whether or not the auction ever fails. The quantitative method behind the sampling is open to inspection, not asserted.

Frequently asked questions
What is the fiscal-dominance scenario for 2026?
It is a modelled — not forecast — 2026 path in which US federal debt near 128% of GDP forces the Fed to hold rates higher for longer, repricing long-duration assets downward. Concentrated tech equity, being almost entirely future cash flows, takes the largest hit. It is one regime in a stress test, not a prediction that it occurs.
How does fiscal dominance actually compress my portfolio?
Fiscal dominance is the mechanism where debt-service cost overrides the central bank’s freedom to fight inflation, so policy keeps real yields elevated. A higher discount rate falls hardest on long-duration cash flows, which is what a single tech ticker is. The repricing arrives through the discount rate, not through earnings.
How likely is this scenario to play out?
It is plausible but unquantified — net interest already runs near $1.0 trillion for the fiscal year, with CPI back at 4.2% and the 10-year near 4.49%, so the pressure is structural rather than hypothetical. The point of the exercise is not a probability estimate but a measured exposure: what a 100bp real-yield shift does to your specific book.
What would trigger fiscal dominance in practice?
The trigger is a Treasury auction that strains demand while inflation stays sticky, forcing yields up and leaving the Fed unable to ease without monetizing the debt. A wobble in bank balance sheets absorbing that supply can accelerate it. The diagnostic flags the real-yield regime at which your position begins to break, before any auction fails.
How do I hedge rate, inflation, and USD exposure here?
You buy convexity that pays into the same shock that compresses your equity, sized as a small persistent cost against a large contingent payout — the tail-risk hedging logic covers the structure. The first step is a known repricing surface: how a defined rate-and-inflation shift hits your single position, exported and auditable rather than assumed.
