Arthur Hayes says he wants the Federal Reserve to raise or remove a $60 billion cap on its FIMA repo facility before he adds more aggressively to Bitcoin and other risk assets. The facility lets foreign central banks borrow dollars against Treasury collateral, and Hayes argues heavier use would temporarily expand the Fed's balance sheet in a way that could lift Bitcoin. For now, the Fed's latest weekly data show zero foreign-official usage, so his trigger has not fired.
Arthur Hayes is waiting on one number before he adds more aggressively to Bitcoin: a $60 billion Federal Reserve cap.
A repo facility built for Japan's yen defense
Hayes's Aug. 11 essay centers on the Foreign and International Monetary Authorities Repo Facility, or FIMA, which lets approved foreign official accounts raise dollars against US Treasury collateral on a temporary basis. A monetary authority pledges Treasuries to the Fed, receives dollars, then sells those dollars for yen — financing currency intervention without an outright Treasury sale. Hayes has already positioned for a rebound in liquidity, keeping more dollars on hand until the Fed revises the rules.
The current FOMC directive caps total outstanding FIMA repo exposure at $60 billion per counterparty, though the Fed's Foreign Currency Subcommittee can alter the rate, maturity, eligible counterparties, or the cap itself.
Bank of Japan data implied Japan may have spent as much as $58.9 billion buying yen on July 30, with a second operation reaching as much as $36.58 billion on July 31, when the United States joined the intervention. Those estimates put the two-day 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 level that has repeatedly drawn intervention. Treasury Secretary Scott Bessent has urged the Fed to expand FIMA, framing it as a way for Japan to obtain dollars against Treasuries rather than sell them outright.
A theoretical ceiling near $1.4 trillion
Hayes assigns over $1.1 trillion of Treasuries to the Japanese government and adds roughly $230 billion held by Japan's Government Pension Investment Fund, for a theoretical total near $1.37 trillion — though GPIF participation would need its own eligibility decision under FIMA's current rules. That figure equals roughly 22.9 times the current $60 billion ceiling, so reaching anything close to it would require a far wider facility before his trigger could activate.
Why Bitcoin sits inside the trade
Large FIMA balances would temporarily add repo assets to the Fed's balance sheet. Hayes treats that expansion as a liquidity impulse for monetary assets, naming Bitcoin, physical gold, and gold miners as his preferred exposures.
His trigger needs two steps: the Fed raising the counterparty limit or broadening eligibility, then the weekly H.4.1 release showing material foreign official repurchase agreements rather than zero. Neither has happened — the Aug. 5 H.4.1 release still shows zero foreign-official repos, leaving the facility dormant.
The risk on the other side
Hayes also flags a bear scenario: a rapid yen rally could force investors to close yen-funded positions across global markets before any FIMA liquidity offsets it, hitting Bitcoin first. He points to the 2024 yen carry unwind as his model for that risk. The estimated $95.55 billion of Japanese intervention across July 30 and 31 still failed to keep the yen far from 160.
