344. Can Stablecoins Save the Dollar

— Stablecoins offer genuine benefits (financial inclusion, inflation protection for citizens in weak-currency countries) but do not materially solve US fiscal problems despite Treasury Secretary claims.

— Academic models and Federal Reserve analysis estimate stablecoins could lower US borrowing costs by only 20–40 basis points even under extremely optimistic adoption scenarios—insufficient to change the debt trajectory.

— Stablecoin growth displaces existing dollar and treasury demand rather than creating entirely new demand; physical cash replacement actually worsens fiscal outcomes because it converts 0% liabilities into 4% interest-bearing obligations.

— The shift from long-term to short-term treasury issuance creates severe rollover risk and vulnerability to interest-rate spikes, particularly if stablecoin redemptions accelerate during market stress.

— Ammous argues Washington is promoting stablecoins less for fiscal benefit and more as political cover for massive crypto profits by Trump administration officials; the arrangement benefits Bitcoin more than the dollar long-term.

— Congressional Budget Office estimates show 10 basis points of yield reduction yields ~$379 billion in cumulative deficit savings through 2036.

— Even under deliberately exaggerated best-case scenarios (stablecoins reaching $20 trillion, investing $16 trillion in treasuries), debt would be only 4–5% lower by 2036—negligible relative to total trajectory.

— BIS research shows stablecoin effects on treasury yields can be up to 3× larger during redemption episodes than issuance, signaling fire-sale risk as stablecoin holdings grow.

— Ammous notes Tether has been converting profits into Bitcoin rather than treasuries, benefiting Bitcoin market more than dollar market due to Bitcoin's smaller cap and greater price sensitivity.

— For Bitcoin holders: Stablecoin adoption accelerates Bitcoin adoption by teaching users digital money practices and private-key handling; every stablecoin failure is bullish for Bitcoin, and stablecoin issuer treasury purchases increasingly flow into Bitcoin, creating tailwinds for adoption and price appreciation.

— For macro investors: Short-term treasury demand concentration via stablecoins increases rollover risk and long-end yield pressure; watch for redemption stress events in crypto markets that could cascade into US funding market dysfunction.

— For USD reserve managers: Stablecoin displacement of physical dollars and long-duration treasuries erodes seigniorage and increases funding fragility; diversification into non-correlated assets (including Bitcoin) hedges concentration risk in runnable stablecoin-backed short-term funding.
