Arthur Hayes says a $60 billion Federal Reserve limit is the next liquidity trigger he wants to see before adding more aggressively to risk assets, such as Bitcoin.
His Aug. 11 essay focuses on the standing Foreign and International Monetary Authorities Repo Facility, or FIMA. The facility allows approved foreign official accounts to raise dollars against US Treasury collateral temporarily.
Hayes has already positioned for a rebound in liquidity, saying he has kept more dollars on hand until the Fed revises FIMA’s rules.
A monetary authority pledges Treasuries to the Fed, receives dollars, then sells those dollars for yen. The structure can finance currency intervention without an outright Treasury sale.
Foreign-official repurchase agreements stood at zero for the week ended Aug. 5, so Hayes’s proposed Bitcoin liquidity channel remains dormant in the most recent H.4.1 release.

The $60 billion cap as a liquidity trigger
The current FOMC directive caps the total outstanding FIMA repo exposure at $60 billion per counterparty at any given time. The Foreign Currency Subcommittee can alter the rate, maturity, eligible counterparties, or counterparty limit, and Hayes is waiting for that authority to open a larger channel.
Bank of Japan data implied that Japan may have spent as much as $58.9 billion buying yen on July 30. A second operation may have reached $36.58 billion on July 31, when the United States joined the intervention.
Those estimates put the two-day Japanese outlay near $95.55 billion, already above one of the current FIMA counterparty limits.
The yen traded around 159.45 per dollar on Aug. 12, close to the 160 area that has repeatedly drawn intervention attention. Treasury Secretary Scott Bessent has urged the Fed to expand FIMA, framing the facility as a way for Japan to obtain dollars against Treasuries and avoid selling those securities in the market.
That sequence creates the policy setup Hayes wants to trade, as Japan has shown a willingness to deploy nearly $100 billion in two days to support the yen and Bessent has publicly pointed toward FIMA as a future backstop.
Hayes then assigns over $1.1 trillion of Treasuries to the Japanese government. He adds about $230 billion in US Treasuries held by Japan’s Government Pension Investment Fund (GPIF), which yields his $1.37 trillion theoretical total.
The Treasury International Capital (TIC) system reported $1.14 trillion of Japan-attributed Treasury holdings in May 2026. TIC data relies heavily on US-based custodians and broker-dealers, so the table does not provide a precise owner-by-owner accounting inside Japan.
The Fed offers the facility to approved FIMA account holders, a group centered on foreign central banks and other foreign monetary authorities with relevant Fed accounts. Hayes explicitly wants broader eligibility, including GPIF-like entities, and the removal of the $60 billion cap.
A $1.37 trillion pool equals roughly 22.9 times the current $60 billion ceiling, so reaching anything close to Hayes’s maximum would require a far wider facility before the liquidity trigger could activate.
GPIF participation would also require an eligibility decision, so Hayes’s headline number describes potential collateral capacity under a different framework.

Bitcoin gets a bull case
Hayes’s bull case requires a larger Fed facility, then foreign official institutions have to draw on it. A FIMA repo temporarily exchanges Treasury collateral for dollars, allowing the foreign authority to access dollar liquidity without selling the securities outright. The repo reverses at maturity.
Large FIMA balances would temporarily add repo assets to the Federal Reserve’s balance sheet. Reports noted that heavy usage would increase Fed holdings for the life of those transactions. Hayes treats that temporary expansion as a liquidity impulse for monetary assets, naming Bitcoin, physical gold, and gold miners as his preferred exposures.
Hayes’s liquidity trigger has two observable steps. The Fed first raises the counterparty limit or broadens eligibility, and H.4.1 then begins to show material foreign official repurchase agreements rather than zero.
A rule revision without usage would leave Hayes’s liquidity trigger inactive.

Strongest liquidity tailwind
The bear case keeps FIMA balances near zero, and Japan would rely on existing intervention resources or tighter domestic monetary policy to support the yen.
Market watchers argued that Japan already has other dollar channels, which could limit demand for an enlarged FIMA facility. That outcome would deprive Hayes’s Bitcoin thesis of the balance sheet expansion he expects.
A rapid rally can force investors to close yen-funded positions across global markets, and that liquidation channel can reach Bitcoin before any FIMA liquidity offsets it. Hayes points to the 2024 yen carry unwind as his model for that risk.
Nearly $95.55 billion of estimated Japanese intervention across July 30 and July 31 failed to keep the yen far from 160. Bessent wants a larger Fed backstop, and the directive still sets the counterparty ceiling at $60 billion.
The Aug. 5 H.4.1 release still shows zero foreign-official repos.
Hayes has reduced a trillion-dollar macro thesis to two observable data points. The first is the Fed rulebook governing FIMA limits and eligibility, and the second is the foreign-official repo line in H.4.1. His Bitcoin liquidity trigger activates only when a broader facility produces real usage.
