Arthur Hayes sees the latest developments in the U.S. Department of the Treasury as something far bigger than just a technical bond-market policy. In his view, Treasury Secretary Scott Bessent is using a mechanism reminiscent of Janet Yellen’s 2023 liquidity strategy—and if dollar liquidity flows back into the financial system, Bitcoin could become one of the biggest beneficiaries.

The trigger for that analysis was the Treasury’s decision to double the size of long-term Treasury buybacks from US$2 billion to at least US$4 billion per operation, starting September 9. The policy came after 30-year Treasury yields hit their highest level since 2007 and U.S. public debt surpassed US$40 trillion.

Why does Hayes see it as bullish for Bitcoin?

The key is liquidity, not just interest rates.

Hayes argues that when the Treasury uses its balance sheet to manage the bond market, and at the same time potentially uses funds from the Treasury General Account (TGA), the money that was previously sitting in the government’s account can flow back into the financial system. The TGA itself is around US$940 billion.

Within Hayes’ framework, the larger the available dollar liquidity, the greater the chances that capital will flow into assets with limited supply—including Bitcoin.

However, there is an important difference: buybacks are not the same as “new money being printed.”

Bessent emphasizes that the Treasury is still following its normal debt issuance schedule and hasn’t bought a single bond under this new structure. So for now, the narrative of “huge liquidity flowing into the market” is still a thesis about the impact of policy, not a fact that US$1 trillion has been injected.

Bitcoin has started to respond already

Interestingly, the crypto market has moved first. Bitcoin is back near US$80,000, while U.S. spot Bitcoin ETFs are recording strong inflows; IBIT even received about US$1 billion over a week, including around US$503 million in a single day.

But a Bitcoin rally shouldn’t be taken immediately as proof that Hayes’ thesis has already been confirmed.

Treasury yields are still high and have risen again after an initial dip. This means the bond market is still facing pressure from fiscal deficits, inflation, government funding needs, and the scale of private-sector investment—including AI infrastructure.

Conclusion

This is the most interesting part of Hayes’ thesis:

If the Treasury starts prioritizing stability in the bond market by using its balance sheet and government liquidity, Bitcoin could be one of the first assets to respond to expectations of increased dollar liquidity.

But investors need to distinguish between liquidity expectations and liquidity that actually enters the system.

For Bitcoin, three indicators are now especially important: TGA balances, the 10Y/30Y Treasury yield, and inflows to spot BTC ETFs.

If all three move in a way that supports each other at the same time, Hayes’ thesis will have much stronger fuel.
