BlackRock's fiscal case for Bitcoin is arithmetically sound and 49% underwater

The average carry implied by Mitchnick's own two figures is about 2.5% ^[15], and that is the part of his argument that holds regardless of what anyone thinks about Bitcoin. Paper issued at that average has to be refinanced at whatever the market charges when it matures, so the interest line grows even if Congress never borrows another dollar. The same pair of numbers implies total federal outlays of roughly $7 trillion, since the interest bill is described as more than 14% of spending ^[16][3]. The mechanism is real and it is not controversial.

What the mechanism does not do is set a price. Mitchnick identified US fiscal deterioration as the most important fundamental driver ahead on June 22, citing rising borrowing and reliance on money printing ^[5]; the source dates that remark by month and day only. Across the window the article covers, the peak-to-mid-June move works out to a 48.8% decline ^[17]. Debt and debt service went the way he said they would. The asset meant to answer them lost nearly half.

The article also asks one number to do two jobs. It reports a drawdown of roughly 49% ^[8] and separately presents the mid-June level as a rebound off the lows that Mitchnick read as selling pressure exhausting itself ^[11]. But 49% off the October peak lands on that same mid-June level ^[17]. Either the trough is below any figure printed here, or the rebound is the drawdown. No low is given, so the stabilization read cannot be checked.

Calling the stalled CLARITY Act less critical for Bitcoin than for the rest of the industry ^[13] is defensible on the merits, given approved spot ETFs and the commodity consensus ^[14]. It also removes the one catalyst that is not macro. If legislation cannot move Bitcoin, and the fiscal argument is a multi-year erosion story, there is no date on which the thesis can be scored.

That leaves the holders. Spot ETFs put traditional asset managers, sovereign wealth funds and pension allocators on the register from early 2024 ^[12], and BlackRock sells IBIT into those accounts as a portfolio diversifier ^[6]. A diversifier that halved while its stated driver worsened, and while the money went into AI instead ^[10], gets discussed at investment committees as a correlation failure rather than as macro foresight. The fiscal case is what remains when the price case is unavailable, and it is also the only one of the two that can currently be put in front of a pension board.
