Coinbase CEO Brian Armstrong: High Interest Rates Drive Up Deficits and Money Printing
Brian Armstrong stated that higher interest rates lead to increased government deficits and more money printing, which causes inflation; lower interest rates help balance the budget. The goal is massive growth, with inflation not exceeding growth; some inflation can be tolerated with high growth. What needs to be curbed is money printing that exceeds economic growth, while maximizing economic growth is essential.
This statement comes in the same week that the Federal Reserve raised interest rates to 3.75%–4.00% on September 16, amid a debate between Ackman and Circle on whether "rate hikes have turned into cost-push". U.S. national debt has reached approximately $39.7 trillion this year, with net interest expenses exceeding $1 trillion, surpassing the defense budget, and the deficit during prosperous times remains around 6% of GDP. Armstrong wrote in July that the Constitution lacks spending caps and hard currency constraints, suggesting the use of hard assets like Bitcoin as a benchmark, and hoping for contributions to growth from AI and robotics.
His transmission chain is fiscally driven: policy rate hikes increase the interest on existing debt, which feeds into the deficit, and the deficit is financed through bond issuance or balance sheet expansion, which he equates to money printing. Unlike Ackman’s view that "AI spending is insensitive to interest rates", Armstrong interprets the same rate hike as a cost shock for the government as the largest borrower. If growth is fast enough, nominal debt can be reduced; if growth is not fast enough, rate hikes are a precursor to accelerated money printing.
Coinbase's business thrives on volatility and trading volume, and also benefits from the narrative of "dilution of the dollar". Stablecoins and Bitcoin are seen as hard currency options in his framework, rather than neutral settlement tools. Writing budget balance as a function of rate cuts equates to rewriting the Fed's tools from inflation management to debt management.
In market mechanisms, what is sold is growth prioritized over tightening, and what is bought is pricing for interest expenses entering the deficit. The bond market absorbs about $2 trillion in net issuance annually, with front-end rate hikes raising refinancing costs. The beneficiaries are crypto platforms that frame fiscal dominance as a reason for Bitcoin, while the pressured party is the Treasury, which must roll over maturing bonds at higher coupon rates. Funds flow from taxes and new debt to interest holders, and then from the "money printing hedge" narrative to Bitcoin and exchanges.

Armstrong replaces the Taylor rule with fiscal arithmetic. The government is the largest floating-rate debtor, where rate hikes first impact interest lines, then deficits, then bond issuance, and are ultimately described as money printing. This contrasts with the textbook notion that "rate hikes suppress demand" but aligns with the reality that net interest has already surpassed defense spending. His hard currency proposal from July is a product of the same logic: using Bitcoin to limit money printing and leveraging AI to raise growth ceilings.
The capital path is to frame the national debt interest crisis as a demand for crypto assets. Coinbase does not hold Treasury securities but has access to the flow of "dollar dilution". If rate cuts are accepted as a budget tool, lower short-term rates benefit risk assets and trading volumes; if rate hikes are viewed as a precursor to money printing, they similarly benefit the Bitcoin hedge narrative. Both paths are not detrimental to exchanges.
Similar arguments can be seen in the mirror of modern monetary theory and emergent fiscal dominance literature: when debt/GDP is sufficiently high, monetary policy loses its independent objective. The industry is at a stage where Fed meetings are interpreted as fiscal events. Whoever first allows the market to focus on interest expenses rather than core PCE readings will redefine the meaning of rate hikes.
Structural judgments belong to the transfer of pricing power. The pricing power of interest rates shifts from demand management to debt servicing. The mechanism is that once existing debt becomes sensitive to policy rates, rate hikes increase interest rather than unemployment; interest is capitalized into the deficit, which is then used as a justification for the next round of monetary expansion.
