Arthur Hayes has identified the $60 billion ceiling set by the Federal Reserve as a potential trigger for a Bitcoin liquidity crisis, arguing it is a necessary precondition for a significant BTC price surge. He maintains that before increasing allocations to risk assets like Bitcoin, investors must first observe this liquidity gateway being opened.
This view directly relates to a structural bottleneck in global macro liquidity, where existing mechanisms cannot accommodate large-scale sovereign capital inflows, thus limiting the upside potential for risk assets. The underlying cause lies in the operational logic of the Foreign and International Monetary Authorities (FIMA) repo facility and its current regulatory restrictions.
The FIMA mechanism allows eligible foreign official accounts to temporarily obtain US dollars by using US Treasury bonds as collateral. Specifically, monetary authorities first deliver Treasuries to the Fed in exchange for dollars, which can then be used to purchase yen, providing funding for currency intervention without the need to sell Treasuries directly. Currently, the Federal Open Market Committee (FOMC) stipulates that the total FIMA repo operations for any single counterparty cannot exceed $60 billion at any time, with the Foreign Exchange Subcommittee having authority to adjust related interest rates, terms, eligible counterparty scopes, and counterparty limits.
Notably, Japan has demonstrated a willingness to spend nearly $100 billion within two days to support the yen, and Bessent has publicly stated that FIMA could serve as a backup support mechanism in the future. Data compiled by WoofunAI shows that the Fed only provides this service to approved FIMA account holders, which are primarily foreign central banks and other foreign monetary authorities with Fed accounts. An article published on August 11 mainly explored this existing mechanism, with Arthur Hayes anticipating the relaxation of these limits to create larger funding channels, a policy environment that aligns with his desired trading conditions.
From an expansion logic and scale comparison perspective, Arthur Hayes explicitly aims to broaden the scope of application to include institutions like Japan's Government Pension Investment Fund (GPIF) and eliminate the $60 billion cap. The GPIF has a scale of $1.37 trillion, roughly 22.9 times the current $60 billion limit. Therefore, to achieve the maximum scale Hayes envisions, a larger financing mechanism must first be established before the corresponding liquidity response measures can be triggered.
For the GPIF to participate, a decision on its eligibility would need to be made first, meaning the number Hayes proposed actually reflects the potential collateral capacity under a different framework. In his bullish logic, the Fed must first provide a larger financing mechanism, after which foreign official institutions can deploy these funds. Through the FIMA repo mechanism, relevant foreign monetary authorities can temporarily obtain dollars by using Treasuries as collateral, gaining dollar liquidity without selling Treasuries, with the transaction being reversed upon maturity.
The liquidity trigger mechanism set by Arthur Hayes includes two observable steps: first, the Fed increases counterparty limits or expands the scope of application, and then the H.4.1 data indicator shows non-zero foreign official repo activity. If only the rules are modified but the mechanism is not actually used, the liquidity trigger conditions Hayes envisions will not be activated. Under a bearish scenario, FIMA balances would remain near zero, forcing Japan to rely on existing intervention tools or stricter domestic monetary policy to support the yen.
The H.4.1 data released on August 5 still shows no foreign official repo activity, indicating that the market remains in a quiet period awaiting a policy breakthrough, with no substantial evidence of a liquidity spillover yet appearing.
