Former BitMEX CEO Arthur Hayes has issued a stark warning: the U.S. Treasury’s growing dependence on debt markets is approaching its structural limits. In a July 3 Substack post, Hayes argued that stablecoins could soon become a crucial new source of liquidity, helping to finance U.S. government debt while indirectly boosting Bitcoin.
Hayes outlined a major challenge facing Treasury Secretary Scott Bessent — the need to sell over $5 trillion in bonds this year to fund deficits and refinance maturing debt, all without driving 10-year yields above 5%. With the Federal Reserve sidelined due to its inflation-fighting stance, the traditional backstop of bond purchases is no longer readily available. This forces the Treasury to seek alternative buyers — and Hayes believes the answer may lie in the stablecoin ecosystem.
His proposal centers on transforming traditional bank deposits into tokenized dollars. Highlighting JPMorgan’s JPMD token, which will operate on Coinbase’s Base network, Hayes sees this as a turning point. By converting deposits into blockchain-based stablecoins, banks could streamline compliance and operations, potentially saving $20 billion annually. These efficiencies would then allow banks to funnel those stablecoin-denominated funds into U.S. Treasury bills.
T-bills, with their low risk and yields close to the Fed Funds rate, offer an attractive return. Hayes estimates this tokenized transition could unlock up to $6.8 trillion in new demand for T-bills. Additionally, a Republican-backed proposal to end interest payments on reserves could push banks to reallocate another $3.3 trillion of idle capital into Treasuries.
Hayes views this mechanism as a modern, private-sector version of quantitative easing. Instead of central banks printing money, liquidity would now be created as banks issue stablecoins and recycle them into government bonds — supporting the dollar, suppressing yields, and indirectly benefiting Bitcoin and other risk assets.
While he cautions that there may be a short-term liquidity squeeze if the Treasury aggressively refills its cash reserves following a debt ceiling resolution, Hayes remains optimistic. To him, stablecoins are evolving beyond payment tools — they’re becoming instruments of macroeconomic policy, intertwining traditional finance with the crypto ecosystem in unprecedented ways.
