Hayes: Fed’s $60B FIMA Cap Is Bitcoin’s Next Trigger

Arthur Hayes wrote in an Aug. 11 essay that the Federal Reserve’s $60 billion per‑counterparty limit on the Foreign and International Monetary Authorities repo facility, or FIMA, is the next liquidity trigger for Bitcoin. He said he will increase exposure to risk assets only if the Fed raises or removes that cap and the facility is actually used.

FIMA allows approved foreign official accounts to exchange U.S. Treasury collateral for dollars through repurchase agreements. The operation supplies dollars temporarily without requiring the foreign authority to sell Treasuries in the open market. The FOMC directive currently caps outstanding FIMA exposure at $60 billion per counterparty. Hayes urged the Fed’s Foreign Currency Subcommittee to broaden eligible counterparties and to lift or raise the per‑counterparty limit.

Hayes cited recent activity around the yen as the likely catalyst. Bank of Japan data and market estimates put Japan’s intervention at as much as $58.9 billion on July 30 and about $36.6 billion on July 31, the second day including U.S. participation. Those two days total roughly $95.6 billion, a sum larger than the current $60 billion cap. Treasury Secretary Scott Bessent has publicly called for expanding FIMA so Japan can obtain dollars against Treasuries rather than selling those securities into markets.

Hayes also provided a theoretical size for the collateral pool he wants eligible. He attributed about $1.14 trillion of Treasuries to the Japanese government in May 2026 and added roughly $230 billion held by Japan’s Government Pension Investment Fund, for a combined $1.37 trillion. That total is about 22.9 times the current $60 billion counterparty limit, so eligibility changes and higher limits would be needed before large official institutions could tap the facility at scale.

Hayes set two observable conditions for his liquidity trigger. First, the Fed must revise FIMA rules to change the counterparty limit or broaden who can use the facility. Second, the Fed’s H.4.1 release must show material foreign‑official repurchase agreements rather than the zero balances reported for the week ended Aug. 5. As of that H.4.1 release, foreign‑official repo balances remained at zero.

Hayes described several outcome paths: no rule change and no usage; a rule change without drawdowns; a raise in the cap followed by material usage; and a scenario in which a rapid yen rally forces carry trades to unwind before any FIMA liquidity appears. He said he has held more dollars on hand and will increase risk exposure only if both a rule change and actual drawdowns occur. The next clear signals would be official action by the Fed’s Foreign Currency Subcommittee and subsequent H.4.1 entries showing material FIMA repo activity.
