BitMEX co-founder Arthur Hayes said on Aug. 11 that a Federal Reserve facility increasingly discussed as part of Japan’s yen defense could eventually create a liquidity tailwind for Bitcoin, Ether and gold. 

In his latest essay, Hayes argued that Japan could pledge U.S. Treasuries through the Fed’s Foreign and International Monetary Authorities Repo Facility, receive dollars, then sell those dollars to buy yen.

Unlike earlier versions of Hayes’s Japan thesis, part of the policy setup is now confirmed. Japan’s Ministry of Finance said it bought yen in coordination with the U.S. Treasury on July 31 and plans to use FIMA in the future. Treasury Secretary Scott Bessent has also publicly encouraged the Fed to increase the facility’s size.

Bitcoin thesis rests on a bigger FIMA facility

FIMA allows approved foreign central banks and monetary authorities to temporarily exchange Treasuries held at the New York Fed for dollars rather than selling the securities outright. Current Fed rules limit outstanding transactions to $60 billion per counterparty. The Foreign Currency Subcommittee can alter the limit and eligible counterparties while keeping the wider committee informed.

Hayes argues that removing or sharply increasing that ceiling could allow Japan to mount larger yen interventions without dumping Treasuries into the market. He said “the more they print, the higher Bitcoin goes,” linking any resulting Fed balance sheet expansion to stronger prices for scarce monetary assets. That relationship is Hayes’s market thesis, not a guaranteed consequence of using FIMA.

The mechanism also differs from conventional quantitative easing. A FIMA transaction is a short term, collateralized repo that must be repaid, with the Fed accepting U.S. Treasury securities as collateral. The facility offers overnight or seven day funding and is designed as a dollar liquidity backstop rather than a permanent asset purchase program.

That distinction matters for the bullish case. A temporary increase in reserve liquidity does not automatically produce the same market effect as permanent Treasury purchases, and Bitcoin’s reaction would also depend on investor positioning, currency moves and the scale and persistence of any FIMA use.

Japan has already confirmed FIMA is part of its toolkit

Japan’s Aug. 3 official statement provides the strongest support for Hayes’s argument. Finance Minister Satsuki Katayama confirmed the July 31 coordinated yen purchase and said Japan “plans to utilize” the Fed facility in the future. The ministry also left the door open to additional joint intervention.

Bessent separately said Washington would be prepared to participate in further intervention and backed a larger Fed liquidity facility. Reuters reported that the Treasury secretary sees FIMA as a way for Japan to raise dollars without forcing Treasury sales into the open market.

The issue has already featured in earlier yen liquidity analysis, when Hayes argued in January that Fed support for Japanese markets could eventually lift crypto through easier dollar liquidity. More recent Japan carry trade coverage showed the opposite risk: higher Japanese yields can reduce cheap yen funding available for global risk trades.

The $1.37 trillion figure needs an important qualification

Hayes estimates roughly $1.37 trillion of potential Treasury collateral, combining Japanese government holdings with around $230 billion held by the Government Pension Investment Fund. Treasury data confirms Japan held $1.1431 trillion of Treasuries at the end of May. Reuters calculated GPIF held another $232.1 billion at the end of March.

However, all $1.37 trillion cannot be treated as immediately available FIMA collateral. Current Fed participation is limited to approved foreign official accounts, while Hayes himself says eligibility would need to expand to include entities such as GPIF.

GPIF’s latest official results still showed its foreign bond allocation near its 25% policy target at the end of June, not evidence that its Treasury portfolio has already been redirected into the facility.

Fed data has not yet confirmed Hayes’s liquidity surge

The latest Federal Reserve balance sheet does not yet show the large FIMA expansion envisioned by Hayes. The Fed’s Aug. 6 H.4.1 release showed just $1 million of total repurchase agreements outstanding as of Aug. 5. That does not identify every policy discussion underway, but it provides no evidence of a large FIMA draw at that point.

Bitcoin likewise has not shown an immediate rally tied to the essay. BTC was trading near $63,977 on Tuesday, while Ether was around $1,625. Those prices do not disprove Hayes’s argument because his thesis depends on a future expansion of FIMA rather than the existing facility alone.

The next measurable trigger is therefore a Federal Reserve change to FIMA’s $60 billion cap or counterparty rules, followed by evidence of actual Japanese usage in weekly Fed balance sheet data. Until then, the bullish Bitcoin, Ether and gold scenario remains a forward looking Hayes thesis built around a policy mechanism that Japan has confirmed it intends to use, but that the Fed has not yet expanded publicly.
